Abstract：
Most previous studies agree that career shocks can be either positively (receiving an unexpected award) or negatively (unexpectedly losing one’s job) valenced. However, due to individual differences in the cognition of events or time factors, this categorization may have some shortcomings. Based on the transactional model of stress and coping, the present study proposes a new classification of career shocks, namely, challenging and hindering career shocks, and further explores the mechanism underlying the impacts of career shocks on individual behaviour based on the transactional model of stress and coping, the job demands-resources model, affective event theory, and event system theory; finally, the paper clarifies when and why career shocks have positive or negative impacts on employees.

Abstract： The innovation process can be conceptualized as encompassing two stages: idea generation and idea implementation. However, to date, more early research has been focused on the idea generation stage, and these two subfields still remain stubbornly disconnected from one another. To integrate these two disparate subfields and advance our comprehensive understanding of the innovation process, the current study relied on self-determination theory and Yale attitude change approach to examine the effect of intrinsic motivational orientation of idea generators on idea quality, and further tested the effect of idea quality, rewards of the idea generators, and their interaction on idea implementation. To test the hypotheses in the proposed model, we collected data from 251 idea generators, 7 idea evaluators and the manager of an innovative proposal project at 3 different time points in a large financial company. In the first wave, 440 ideas proposed by 440 idea generators were recorded. In the second wave, all of the idea generators were invited to complete a questionnaire, including demographic information and intrinsic motivational orientation, and the number of valid questionnaires was 251; moreover, 7 in-house experts assessed the idea generators and the quality of each idea. Approximately six months later, the manager of this project reported the implementation degree of all of the ideas. Our hypotheses were examined using SPSS 22.0. By analyzing the multi-time and multi-source data, it was found in this study that: (1) intrinsic motivational orientation of the idea generators has a significantly positive effect on idea quality; (2) idea quality further facilitates idea implementation; (3) rewards of the idea generators positively influence idea implementation; and (4) idea quality and rewards of the idea generators interact to predict idea implementation.The findings presented here contribute to innovation literature in the following ways. First, this study tracks the innovation process from idea generation to idea implementation, bridging the theoretical divide between creativity research and idea implementation research. Second, this study clarifies the positive effect of intrinsic motivational orientation on idea quality, which is a beneficial supplement to, and promotion of the existing research on the relationship between intrinsic motivation and creativity. Third, Yale attitude change theory is introduced into idea implementation research, which not only expands the application scope of this theory, but also enriches theoretical perspectives of idea implementation research.

Abstract：通过实海暴露实验，研究了N6纯镍和Monel400镍合金在中国南海海域800米和1200米深海环境下的长周期（3年）腐蚀行为。采用SEM，EDS和XRD技术，分别进行了腐蚀形貌观察，腐蚀产物成分和相组成分析。结果表明：在深海环境下，Monel400镍合金的耐局部腐蚀能力要优于N6纯镍。N6纯镍在绿色腐蚀产物膜（由NiCl2?6H2O组成，还覆盖有少量的CaCO3、MgCO3等无机盐类）下面发生了很严重的隧道腐蚀，甚至出现了局部穿孔现象。Monel400镍合金表面生成了宽浅型的点蚀坑，点蚀坑上覆盖有由(CuNi)2Cl(OH)3组成的腐蚀产物。将本文中的实验结果与文献中同种合金的实验结果对比作图，表明N6纯镍和Monel400镍合金的最大点蚀坑深度均随水深的增加而降低。

Abstract：通过不同热机械处理工艺，分别获得片层珠光体、球化珠光体、超细化（α+θ）复相组织以及细晶（α+θ）复相组织等4种不同组织的共析钢；利用室温单轴拉伸实验、SEM和TEM等手段研究了上述组织对共析钢室温加工硬化行为的影响。结果表明：片层珠光体组织具有抗拉强度高、屈强比小且均匀延伸率低的特点，这与其初始加工硬化率高、加工硬化率随应变量增加而下降的程度有直接关系。其它3种铁素体/渗碳体粒子复相组织的初始加工硬化率较低，但下降趋势较缓，表现出较好的塑性变形能力。与球化珠光体相比，组织细化使超细化（α+θ）复相组织和细晶（α+θ）复相组织具有更好的强度与塑性配合。

Abstract：利用Gleeble-1500热模拟实验机对10Cr12Ni3Mo2VN钢进行压缩实验，研究了变形温度为850~1200 ℃，应变速率为0.01~10 s-1条件下的热变形行为。结果表明，随变形温度升高、应变速率降低，再结晶晶粒尺寸增加。变形温度1200 ℃，经60%压缩变形后，应变速率较高时再结晶晶粒呈等轴状，应变速率较低时出现混晶。通过传统直线拟合方法和Levenberg-Marquardt算法分别建立了热变形双曲正弦本构方程，采用Levenberg-Marquardt算法可以一次性求解所有材料参数，求解步骤简单，结果可信，Levenberg-Marquardt算法所得本构方程预测精度较传统方法更高。利用加工硬化率-应力（θ-σ）曲线，通过二次求导，准确测得临界应变，并建立了临界应变、峰值应变与Zener-Hollomon因子（Z因子）之间的关系方程。
