Abstract： Elderly patients with type 2 diabetes mellitus often face the problems of multimorbidity and multiple medications，and these conditions often lead to irrational or inappropriate medication use，significantly affecting patient outcomes and quality of life，making early and effective medication decisions particularly important. As an important supplement to medication support information，decision support tools，including electronic health record-based systems，mobile applications，online health platforms，etc.，provide personalized，evidence-based medical information to help patients understand medication regimens，assist patients and healthcare professionals in making more rational medication decisions，enhance the appropriateness and safety of medication，and reduce the risk of drug interactions，thereby improving the overall treatment of patients and reducing the risk of drug interactions. The application of medication management in elderly patients with type 2 diabetes mellitus has made significant progress，thus improving the overall outcome and quality of life of patients. This article summarizes the current situation of medication use in elderly patients with type 2 diabetes mellitus，the influencing factors，types，application methods and their roles of decision aids，aiming to provide reference for the development of medication decision aids for this population in China.

Abstract： [Purpose/significance] Today, great changes have taken place in the library information service environment, this paper aims at providing the design and implementation methods for constructing the workflow-driven and context-sensitive resource discovery system. [Method/process] By analyzing the characteristics and the changes of information services environment and demands in current information service institutions, investigating the current application status of domestic academic resource discovery system, we summarized the shortcomings of the resource discovery system introduced by domestic information service institutions, and these shortcomings appear in the user authority control function and the service workflow design. Then, we put forward the idea of constructing a workflow-driven and context-sensitive resource discovery system, and the specific implementation methods are also introduced. [Result/conclusion] The design and implementation methods introduced in this paper have been successfully applied in the integrated services environment of Guangdong Science and Technology Library. It can be a reference for building a practical academic resource discovery and delivery system with similar application environment and requirements in China.

Abstract： As phase change heat storage material (PCM), composites of paraffin/expanded graphite of different particle sizes (DPS-EG) were prepared by melt blending method, which were then characterized by means of XRD, FT- IR, SEM, DSC and LFA. The effect of mass fraction of DPS-EG on performance of the composite PCM was studied. Results show that the thermal diffusivity of the composite PCM increased first and then decreased with the increasing mass fraction of small particle sized EG. When the ratio of mass fraction for large sized ones to the small ones of the DPS-EG was 9:1, paraffin may be allowed to fill fully into the free space of the mosaic structure of DPS-EG. The thermal diffusivity of the composite PCM was up to 1.964�10-6 m2/s, 22 times higher than that of pure paraffin, while its latent heat was 144.2 J/g.

Abstract：为选择抗旱优良的唐古特白刺家系，本实验于2015、2016年和2018年分别对来自兰州和武威试验点的31个唐古特白刺家系进行可溶性糖（SS）、可溶性蛋白（SP）、游离脯氨酸（Pro）、过氧化氢酶（CAT）、过氧化物酶（POD）、超氧化物歧化酶（SOD）以及叶绿素（Chl）含量测定，运用主成分分析法和隶属函数法对家系抗旱性进行综合评价选择出抗旱优良家系并进行对比分析。结果表明：运用2种综合评价方法结果重合率在80%以上，以20%入选率选择抗旱优良家系，2试验点的j3-9、jc-8、w3-15、w3-12等4个家系在2015年、2016年均入选，在2018年抗旱性明显优于其他家系，入选家系在不同年份不同试验点的抗旱性表现一致，说明唐古特白刺抗旱优良家系在不同生理阶段不同环境下抗旱性表现稳定，对其进行早期选择具有可靠性。
