Abstract： Maternal sensitivity plays a pivotal role in the child's development. A large number of studies have proved the influence of attachment on maternal sensitivity. However, these studies ignored the relationship between attachment styles and cognitive processes of maternal sensitivity, and therefore cannot answer how attachment styles can affect maternal sensitivity The social information processing model of maternal sensitivity integrates crucial cognitive structures and cognitive processes related to maternal sensitivity and divides the cognitive processes of maternal sensitivity into four stages. Based on this model, we reviewed individual differences and mechanisms related to attachment styles at all four stages of maternal sensitivity: emotional perception, maternal attribution, motivational response, and response selection. Future research should further investigate the influence of attachment styles on the cognitive processes of maternal sensitivity from a temporal perspective. Additionally, research should explore the joint influence of multiple cognitive structures on cognitive processes related to maternal sensitivity. Furthermore, attention should be paid to the role of environmental factors in attachment styles and the cognitive processes of maternal sensitivity. Finally, future research should explore the dual influence of attachment style on the cognitive and emotional processes of maternal sensitivity.

Abstract： Effect of hydrostatic pressure on the electrochemical corrosion of X100 pipeline steel in 0.5 mol/L NaHCO3+0.03 mol/L NaCl solution was investigated by means of methodspotentindynamic polarization, electrochemical impedance spectroscopy and Mott-Schottky. The results show that with the increasing hydrostatic pressure the number and the size of corrosion pits increase, while the activity of ions in the solution also increases, which in turn promotes the adsorpting of Cl- in the passive film. As a result, the corrosion rate and the corrosion current density are increased. The component of the passive film transforms from oxide or hydroxide formed by low pressures to carbonate by high pressures, which may result in the decrease of corrosion-resistance and increase of probability of pitting corrosion nucleation. The passivation film formed on the X100 steel exhibits characteristics of n-type semiconductor. The increase amount of Cl- in the passivation film promotes the increase of lattice imperfections and facilitates the cracking of the oxide film.

Abstract： The corrosion behavior of X70 pipeline steel in a near-neutral pH solution NS4 with and without sulfate-reducing bacteria (SRB) respectively was studied by means of electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and microscopic observation. The results showed that the corrosion rate of X70 steel increased with time in NS4 solution without SRB; The growth process of the SRB in the solution NS4 can be divided into three phases: logarithmic phase (1~3 d), stable growth phase (4~7 d) and death phase (7~14 d). The influence of SRB on the corrosion rate of X70 pipeline steel in the solution NS4 with SRB was related to the growth process of SRB. A compact biological film could form on the steel surface in the stage of logarithmic phase and stable growth phase, which was conducive to enhancing the protectiveness of corrosion products on the steel and therewith the corrosion rate of X70 steel in the NS4 with SRB was lower than that without SRB. While the corrosion of X70 steel in the NS4 with SRB in the death phase was more serious than that without SRB, while the scale of corrosion products became thicker gradually, then the biological film broken and therewith the corrosion rate increased.

Abstract： The electrochemical corrosion behavior of hydrogen- charged base metal and welded joint of X80 pipeline steel in a near-neutral solution was studied by means of potentiodynamic polarization and electrochemical impedance spectroscopy. The morphologies of the base metal and the welded joint of X80 pipeline steel were observed by optical microscopy and the content of released-hydrogen were measured, respectively. It was found that charged-hydrogen had little effect on the microstructure of X80 pipeline steel. The hydrogen content of the welded joint is higher than that of the base metal under the same hydrogen charging condition. The base metal demonstrated higher corrosion resistance than the welded joint when they were not hydrogen charged. However, the charged hydrogen facilitated the anodic dissolution of the base metal and the welded joint of X80 pipeline steel, and the corrosion were accelerated in the near-neutral solution with the increase of charging time. Due to pinning effect on the hydrogen induced by the higher concentration of dislocations defects, the welded joint showed better corrosion resistance than that of the base metal.

Abstract： The stress corrosion cracking (SCC) of X80 steel in a simulated soil solution of Yingtan area at Southeast China under cathodic polarization was studied by means of electrochemical impedance spectroscopy, slow strain rate test and scanning electron microscope. The results show that the charge transfer resistance at the steel/solution interface first rises then falls. The cracking mechanism of X80 steel is anodic dissolution under the open circle potential with the potential moving negatively. The SCC reaches a minimum at -1000 mV (vs SCE), which is the optimum protection potential. As the level of cathodic polarization continuously raises, the SCC sensitivity increases. The cracking mechanism of X80 steel is hydrogen induced cracking under the synergistic effect of stress and hydrogen when the applied potential lower than -1100 mV (vs SCE).

Abstract： Effect of temperature on corrosion behavior of X70 pipeline steel in high pH solution (0.5 mol/L Na2CO3+0.5 mol/L NaHCO3) was studied by means of potentiodynamic polarization, electrochemical impedance spectroscopy and Mott- Schottky measurements. Results showed that the pitting potential, passive current density and the polarization resistance of X70 pipeline steel all decreased with the increase of temperature. In the experimental temperature range, the formed passive film consisted mainly of Fe2O3 and Fe3O4 with features of n-type semiconductor. With the rising temperature, the thickness and donor density of the passive film increased, correspondingly, corrosion tendency of the steel increased. Therefore, the stability of the passive film decreased with the increasing temperature, which weakened the corrosion resistance of the X70 steel.

Abstract： Lakes in the Yangtze River Economic Belt are mainly distributed in the Hengduan Mountain area in Southwest China and the flood plain area of the Yangtze-Huaihe River Basin in East China. The high spatial variability of natural environment and economic development have rendered the ecological and environmental problems of these lakes. Comprehensive improvement of the lake environment and their ecological states are important for regional development. In the absence of long-term monitoring data, past environmental changes based on lake sediments, also termed as paleolimnological studies, can provide historical information for the protection and restoration of these lakes. This study revealed better water quality in alpine lakes than low-altitude ones in southwest China, while the worst water quality in the shallow lakes in the Jianghuai region. Furthermore, based on paleolimnological analysis, this study provided a long-term perspective to reveal the evolution characteristics and the mechanisms responding to the changes in climate, hydrology and nutrition in different lakes of the two areas in the past century. Such research also elucidated the reasons of the lake degradation in recent years, and exhibited the advantage of paleolimnological studies in defining reference conditions for ecosystem restoration, management evaluation, community structure optimization during aquatic vegetation restoration, early warning signals of ecosystem critical transition, and ecological safety assessment. Aiming at above environmental problems faced by lakes in different regions, the study put forward several targeted measures for their protection and restoration.

Abstract： Autobiographical Memory is the memory of personal experiences. Attachment theory provides an important framework for understanding autobiographical memory. Based on the differences in individual attachment styles and the Self-Memory System of Conway and Pearce’s, this article concludes that attachment system plays the role of target director, defensive exclusion and emotion regulation in autobiographical memory retrieval. Studies have found that secure individuals have advantages over insecure ones in the quantity, specificity, accuracy, accessibility, emotional intensity and arousal of memory retrieval. Future research can be carried out on the effects of attachment activation, the differences in specific components of memory retrieval between anxious and avoidant attachment styles, the relationship between attachment and retrieval of involuntary autobiographical memory.

Abstract： Previous studies based on attachment theory have proved the influence of attachment on emotion regulation. These influences can be manifested in many aspects, such as the choice of emotion regulation strategies, the effect of emotion regulation, and some cognitive processing related to emotion regulation. However, these studies ignore the complexity and diversity of emotion regulation as a process, and therefore cannot answer how attachment can affect emotion regulation. The extended process model divides emotion regulation into three stages, and clearly describes the process of emotion regulation and the relationship between various factors in the process. Combining the extended process model and the attachment theory to look back to previous studies is helpful to find out the relationship among these studies and expand new research directions. From the perspective of the extended process model, it can be found that there are individual differences related to attachment in all the three stages of emotional regulation. Specifically, in the recognition stage, the influence of attachment on emotion regulation is mainly reflected in the cognitive processing related to emotions. Both higher attachment anxiety and attachment avoidance are related to lower emotion recognition ability. At the same time, higher attachment avoidance is related to lower emotion recognition ability, and higher attachment anxiety is related to lower emotion regulation self-efficacy. In the selection stage, individuals with different attachment styles have different preferences for the choice of emotion regulation strategies. Most studies have found that individuals with secure attachment prefer to use highly adaptable and efficient strategies (such as cognitive reappraisal), and individuals with insecure attachment styles prefer to use strategies which are less adaptable and efficient(such as hypo-regulation or hyper-regulation). In the implementation stage, most studies have found that both attachment anxiety and attachment avoidance are significantly positively correlated with emotion regulation difficulties or disorders, but in some studies, high attachment avoidance individuals may not have problem with emotion regulation. In general, many factors are influenced by attachment in the process of emotion regulation, and the extended process model provides a theoretical framework for describing the sequence and causal relationship between these factors. However, there are still many key issues that have not yet been resolved. Future research can be expanded from the following aspects: The influence of attachment on emotional regulation should be explored while paying attention to the impact of environmental factors; New experimental paradigms need to be designed to confirm the continuity of the three stages and explore the reasons why attachment could affect emotional regulation. It is necessary to explore the influence of attachment on the emotion regulation flexibility. In addition, future intervention studies should design more targeted interventions to improve the emotion regulation of insecurely attached individuals.

Abstract： Relationship maintenance helps individuals deal with threats, improve the probability of survival and reproduction, enhance individual happiness and promote social harmony, which is a series of strategies, including threat mitigation strategies (e.g., positive reframing), relationship enhancement strategies (e.g., social support), and maladaptive relationship maintenance strategies (e.g., compromise), used by individuals to establish, maintain, repair and enhance interpersonal relationships. Although relationship maintenance strategies play a role in forming good relationships with others and enhancing personal well-being, they also increase the risk and pain that accompanies rejection. Interpersonal gratitude, generated from high-quality interpersonal interaction, is a positive emotion pointing to praising others when individuals receive benefits or kindness from another person’s actions and their own needs are met which helps to inhibit self-protection motivation and activate relationship maintenance motivation. Previous studies have found that interpersonal gratitude has a positive impact on relationship maintenance, but, to our knowledge, there is still a lack of systematic combing of the manifestations of interpersonal gratitude in relationship maintenance and the underlying mechanisms of the effect of interpersonal gratitude on relationship maintenance. Therefore, the goal of the current study is to review the relationship maintenance function of interpersonal gratitude. The main functions of interpersonal gratitude in the interpersonal relationship are three aspects: threat mitigation, relationship enhancement, and maladaptive relationship maintenance. Specifically, when interpersonal relationships are threatened, interpersonal gratitude helps individuals to repair interpersonal relationships through threat mitigation strategies at the intrapersonal and interpersonal levels; When the threat is removed, interpersonal gratitude promotes the development of relationships by enhancing the willingness of individuals to maintain relationships, affirming the importance of partners and encouraging partners to further maintain interpersonal relationships. However, it is also worth noting that interpersonal gratitude may make individuals adopt maladaptive relationship maintenance strategies to maintain contact with others as well which is against their own will and social norms. In addition, based on the risk management theory of relationship maintenance, the current study proposes a risk management model to explore how interpersonal gratitude influences relationship maintenance. The model suggests that interpersonal gratitude makes individuals more willing to adopt relationship maintenance strategies to repair and promote interpersonal relationships through the improvement of self-evaluation and others-evaluation. Interpersonal gratitude, on the one hand, will broaden personal resources and improve self-evaluations; on the other hand, it also contributes to finding high-quality partners and binds individuals by building close interpersonal relationships to improve others-evaluation. Although previous studies have examined the relationship between interpersonal relationships and relationship maintenance, there are still some questions that need to be deeply discussed to better improve interpersonal relationships by enhancing interpersonal gratitude. First of all, given that interpersonal gratitude derives from interpersonal interaction between the benefactor and the recipient, future research thus should focus on the positive effects of interpersonal gratitude on relationship maintenance from a dyadic perspective to explore whether and how the expression of gratitude from the recipient enhances the benefactor’s motivation of relationship maintenance by the mediating effects of self-evaluations and others-evaluations; Second, exploring the role of self-evaluation and others-evaluation in the impact of interpersonal gratitude on relationship maintenance from the perspective of multi-evaluation; for example, the role of self-evaluation and others-evaluation could be taken into account at the same time and compare the different effects between implicit and explicit evaluations. In the end, the study of the relationship maintenance function of interpersonal gratitude could be further tested using various methods. it is necessary to explore whether there are cultural differences in the effect of interpersonal gratitude on relationship maintenance. A longitudinal study design should be used to test the impact of social change. Meanwhile, verifying the risk regulation theory of interpersonal gratitude influencing relationship maintenance is an effective way to reveal the underlying mechanisms of the effect of interpersonal gratitude on relationship maintenance from the perspective of multimodal neuroimaging.

Abstract： Anxiety detection and extinction of anxiety-susceptible groups have long been a hot topic of anxiety research. However, the current studies on anxiety detection and extinction lack objective and direct techniques, and are also unclear in terms of the it's functional mechanism. To generate new insight, using a multi-methods approach involving questionnaire, behavior, hormone, and fMRI, the present project aims to explore the mechanism of oxytocin in the detection and extinction of anxiety in individuals with high attachment anxiety. To this end, anxiety detection and extinction are creatively integrated into the framework of oxytocin research with the hope of conducting this project from three aspects. This project aims to provide a new approach to anxiety detection and extinction from the perspective of physiological measurement and pharmacological intervention. Specifically, the details of the research program are as below: Firstly, is there a direct relationship between endogenous oxytocin and anxiety response? To answer this question, Study 1 intends to investigate whether endogenous oxytocin can accurately identify anxiety responses induced by dynamic angry faces, and to clarify the validity of endogenous oxytocin in anxiety detection. We predicted that dynamic angry facial expressions will evoke lower endogenous oxytocin levels than those in static angry and neutral facial expressions during the task period. Secondly, how does oxytocin act on anxiety detection and extinction in individuals with high attachment anxiety? And what is the corresponding brain mechanism? For this purpose, Study 2 design two experiments to explore the neural mechanism of oxytocin in anxiety detection and extinction in individuals with high attachment anxiety from both endogenous and exogenous sources. Experiment 1 mainly focuses on the role of endogenous oxytocin on anxiety detection in individuals with high attachment anxiety, hypothesizing that individuals with high attachment anxiety would exhibit greater amygdala activity and lower endogenous oxytocin levels during the viewing of dynamic angry facial expressions. Experiment 2 mainly focused on the anxiolytic effect of exogenous oxytocin, hypothesizing that intranasal oxytocin will significantly attenuate the amygdala activity during the viewing of dynamic angry facial expressions. Thirdly, whether the effect of oxytocin on anxiety detection in individuals with high attachment anxiety from an intervention perspective could be verified? To further validate the relationship between oxytocin and anxiety response, Study 3 aims to conduct an attachment security intervention for individuals with high attachment anxiety by adopting attachment security priming. During this intervention, the change of endogenous oxytocin and amygdala activation in anxiety response of individuals with high attachment anxiety under intervention training is investigated. Attachment security priming was predicted to significantly attenuate amygdala activity and increase endogenous oxytocin levels during the viewing of dynamic angry facial expressions in individuals with high attachment anxiety. The above three studies were designed to construct a closed-loop of endogenous—exogenous—endogenous to systematically investigate the mechanism of oxytocin in anxiety detection and extinction in individuals with high attachment anxiety. The findings of the project attempt to provide a possible explanation for the mechanism of anxiolytic effects of oxytocin, which is of great scientific implications for understanding the neurohormonal mechanism in the anxiety response. Moreover, the project provides a new approach to anxiety assessment and intervention for high attachment anxiety groups, which is of great value in maintaining and improving the mental health of individuals.

Abstract： People differ in adult attachment style perceive and regulate their social relationships and emotions in the different ways. Previous researches have investigated the efficiency and preference of emotion regulation strategies among different attachment styles and found that the secure attachment individuals tend to reappraise the context and reinterpret events in a mildly way while the avoidant individuals prefer to deactivate the distressed experience and suppress emotional expression. However, empirical evidences were still lacked when exploring the temporal dynamics of the neural processes. The current study tends to fill this research gap by using event-related potentials (ERP) to investigate how avoidant and secure attachment individuals differ in their two emotion regulation strategies: cognitive reappraisal and expression suppression, in lovers intimate scenarios. Forty-three participants (twenty-two avoidant and twenty-one secure attachment individuals), ages of 18–25 years, participated in the study. The experiment consisted of two sessions. In the first session, participants were instructed to freely view (VIEW) and to respond naturally to the content without trying to alter the upcoming emotions. In the second session, participants were instructed to regulate their emotions either in a reappraisal way or in a suppression way. Results showed that: (1)secure attachment individuals reported significantly higher level of pleasure than the avoidant individuals in response to the intimate pictures; (2) secure individuals reported significantly higher level of valence and arousal scores than the avoidant individuals in the emotion regulation condition. ERP analysis further indicated that the mean amplitude of the LPP in response to the intimate pictures in the secure individuals when adopting the cognitive reappraisal strategy was significantly lower thanwhen they in the free-viewing condition in five time windows. However, when using expression suppression strategy, secure individuals showed a significantly reduced LPP amplitude in 300–500, 500–700 ms time windows, compared with the free watching conditions, and showed increased LPP amplitude in 900–1100 ms and 1100–1300 ms time windows. For avoidant individuals, which they used expression suppression strategy, the pictures evoked a significant lower LPP amplitude compared to free-viewing condition in the five time windows. However, there was no significant differences when they used reappraisal strategy compared to spontaneous watching. In sum, there were significant differences both in the subjective emotional measures and electrophysiological responses in response to the lover’s intimacy pictures between the avoidant and secure attachment individuals which they used either the cognitive reappraisal or the expression suppression to regulate their positive emotions. At an early phase of positive emotion regulation, secure individuals applied cognitive reappraisal strategy to regulate emotions efficiently or sustainably, while the avoidant individuals used expression suppression strategy. This study enriched the theoretical relationship between the different emotion regulation strategies and attachment styles, and broadens the research width of emotion regulation and attachment, which can further provided theoretical basis for future researches focusing on the emotion regulation.

Abstract： Oxytocin is known as the "hormone of love" and is closely associated with attachment.Previous studies have proved that oxytocin from different sources has different effects on the interpersonal adaptability of individuals with insecure attachment, mainly shown in the following ways that the lower levels of endogenous oxytocin, the worse the interpersonal adaptibility among insecurely attached individuals; Exogenous oxytocin enhanced the interpersonal adaptability among avoidantly attached individuals, but reduced the interpersonal adaptability among individuals with high anxious attachment scores; A and G Alleles were associated with interpersonal adaptibility among insecurely attached individuals. In addition, attachment theory and the social salience hypothesis are also used to explain the above effects. Defensive exclusion, external contextual factors and individual differences are also play a regulatory role that cannot be ignored. We should compare the differences between the oxytocin receptor gene and the interpersonal adaptability among insecurely attached individuals in the future. Moreover, the effects of oxytocin may have gender differences on interpersonal adaptability among individuals with insecure attachment. However, till now there are few related study focused the above question, thus it deserved to be discussed more in the future. In order to enhance the ecological validity of oxytocin related researches, future researches focused on the effects of oxytocin on the interpersonal adaptability of insecurely attached individuals should be continued studying in the process of interpersonal interaction.

Abstract： " Aiming at the cognition processing defects of individuals with insecure attachment, present study aims to explore the plasticity of insecure attachment and it’s neural mechanism by virtue of attachment security priming. The plasticity of insecure attachment is achieved through the cognitive priming techniques which put insecure individuals in a sensitive and supportive environment. Attachment security priming awakens people’s positive attachment experiences, builds new cognitive schema about attachment relationships, finally, realizes the reconstruction of the internal working model of insecure individuals. Using the behavior-physiology-neural techniques, present study systematically investigates the occurrence mechanism and neural basis of the plasticity of insecure attachment through three aspects. First, examining the effect of conscious and unconscious attachment security priming on cognition processing defects of insecure individuals. Second, exploring the effect of repeated attachment security priming on cognition processing defects of insecure individuals. Third, conducting a longitudinal study to track the effect of the repeated attachment security priming. Present study provides a new perspective for the research of insecure attachment. The attachment schema reconstruction theory developed by present study is the verification and development of the secure-base schema theory. In addition, the examination of repeated attachment security priming effect attempts to build an evaluation standard for the plasticity study of insecure attachment. The present study contributes to the intervention training, the promotion of attachment safety, and the maintenance of mental health for insecure attachment.

Abstract： Abstract: Fuzziness widely exists in many spatio-temporal applications. The existing spatio-temporal data models lack the ability to describe and represent the internal mechanisms or semantic relation of fuzzy spatio-temporal objects. After investigating the semantics of fuzzy spatio-temporal data, a formal definition about fuzzy spatio-temporal data model is proposed. On this basis, the UML data model is extended to express fuzzy temporal and spatial data. Finally, the potential usefulness of our proposed method is demonstrated with an example.)
