高密度聚乙烯/双醛淀粉复合材料的制备及性能的研究

采用单螺杆挤出机制备了高密度聚乙烯/双醛淀粉复合材料,并利用悬臂梁冲击试验机、熔融指数仪、多功能塑料球压痕硬度仪等仪器分析了该复合材料的冲击强度、硬度、熔融指数以及疏水性等性能.实验数据表明,随着体系中双醛淀粉含量的增加,HDPE/双醛淀粉复合材料的疏水性及流动性能有较大的提高,而冲击强度及硬度有所下降,当添加10﹪¹5﹪双醛淀粉时其综合性能最好.     

一种预测磁光盘可靠寿命的方法

提出了利用威布尔分布参数的图分析法预测磁光盘可靠寿命的方法，克服了以往仅针对单一或特定结构的分析，将磁光盘作为一个系统来综合考察，以误码率作为磁光盘的失效判据，通过对磁光盘两个温度点的高温恒定应力加速寿命试验结果的分析，计算出了磁光盘在 ２５℃正常大气条件下的可靠寿命。

Total restrained domination in claw-free graphs

A set S of vertices in a graph G=(V,E) is a total restrained dominating set (TRDS) of G if every vertex of G is adjacent to a vertex in S and every vertex of V−S is adjacent to a vertex in V−S. The total restrained domination number of G, denoted by γ _tr (G), is the minimum cardinality of a TRDS of G. In this paper we characterize the claw-free graphs G of order n with γ _tr (G)=n. Also, we show that γ _tr (G)≤n−Δ+1 if G is a connected claw-free graph of order n≥4 with maximum degree Δ≤n−2 and minimum degree at least 2 and characterize those graphs which achieve this bound.

马克思主义指导研究中国哲学的经验与启示——任继愈的中国哲学史研究成就

任继愈是二十世纪五、六十年代我国大陆中国哲学史研究领域的唯一指导原则"对子论"的主要代表之一,八十年代实现了研究指导思想的自我突破,以"对子论"与"圆圈论"结合,主编了巨著<中国哲学发展史>,他的学术成果,为后人继续研究提供了基础,其学术研究道路对后继者具有多方面的启示.     

从知本经营的角度探求高校债务偿付的新途径

当前我国高校债务化解的具体做法主要有两种：一是土地置换,二是争取财政专项支持。从知本运营的角度看,高校债务化解应探索知本与资本对接,以知本运营的成果偿付高校债务,尝试高校自主运营和委托外部运营的知本运营偿付债务模式。     

群众利益诉求表达机制的构建与探索——以安徽省群众利益诉求基本数据调查与分析为例

从安徽省群众诉求有关数据调查的基本情况看,广大群众对我们党和政府充满了期待和信任;在社会转型期各种矛盾和各种诉求增多是一种必然趋势;当前群众最关心、最有可能提出诉求的主要问题大多数都集中在经济领域;加快收入分配改革以缩小收入差距显得更加紧迫和必要;为此提出了群众利益诉求表达机制构建的对策和思考。     

A model of work–life conflict and quality of employee–organization relationships (EORs): Transformational leadership,procedural justice,and family-supportive workplace initiatives

This paper tested a new model of employee–organization relationships (EORs) by introducing types of work–life conflict as variables leading to EOR outcomes, and by investigating the possible effects of transformational leadership, procedural justice, and family-supportive workplace initiatives upon employees’ perceptions of work–life conflict and relationships with their employers. Data were collected from a survey of 396 U.S. employees. Hierarchical Linear Modeling (HLM) was adopted to address the multilevel structure of collected data. Time-based work–life conflict, individualized consideration, and procedural justice were found to be associated with quality of EORs significantly. Fair work–life policy-making procedures also significantly predicted perceived levels of work–life conflict.
