追求现实社会主义人的全面发展的必然性

21世纪之初,江泽民提出了实现现实社会主义人的全面发展的目标。人的全面发展不仅是马克思主义关于建设新社会的本质要求,而且是当代社会发展理论的新概括;现实社会主义人的全面发展,则是在上述理论指导下研究中国特色社会主义建设实际得出的新结论。     

均匀电场对池沸腾换热的影响分析

对均匀高压电场作用下平板池沸腾换热的强化效果进行了试验研究,发现在较低过热度的范围内电场对换热有明显的强化效果.场强越高,相同过热度对应的换热系数越高.在相同的场强下,强化系数随着热流密度的增加而减少.结合试验结果对电场强化沸腾换热的机制进行了分析.在热流密度较小的范围内,对流换热占主导地位,电场强化对流换热使壁面过热度大大下降,导致相应过热度下汽泡的平衡半径提高,因此,抑制了核态沸腾.随着热流密度的提高,汽泡的产生和运动成为影响换热的主要因素,此时过热度的变化不是很大,在相同的过热度下,电场可以减小汽泡的临界半径,使汽泡增多.在汽泡准备区,电场会影响汽泡的核化;在汽泡成长区,电场会影响汽泡的长大、变形和脱离;在非沸腾区,电场会影响单相流体的自然对流换热.     

传播领域的第三人效应及其影响因素

第三人效应（The third—person effect TPE）最早由美国哥伦比亚大学戴维森（W．P．Davison）教授1983年提出，它是指个体倾向认为大众媒介信息对他人比对自己有更强的影响效果。第三人效应的假设得到验证之后，其影响因素如信息类型、社会距离、个性特点等越来越成为研究的热点。     

水平新型微肋管内流动冷凝换热及流阻特性

为研究微肋管结构尺寸及工况等对管内流动冷凝性能的影响，采用R22为工质对4种结构的微肋管和1根Ф9．52mm光管进行了实验．根据实验结果分析了质量流速、微肋结构尺寸和管径等对冷凝换热性能的影响．实验结果表明，两根Ф9．52mm微肋管的换热系数分别比光管提高了90％和120％，而其内表面积只比光管增加了40％和70％．

Value creation through collaborative supply chain: holistic performance enhancement road map

This paper proposes an integrated novel framework between B2B-SCM using data mining techniques such as K-Means based on particle swarm intelligence (particle swarm optimisation) and association rule. It constructs relationship rules of holistic performance enhancement road map. The data-set of relationships between enterprise and its direct customers of the case study organisations in France was used for demonstration. The experiment results show how domain managers powerfully utilise the graphical analysis results to provide the holistic performance improvement and weakness resolution relationship rules. In the long run, organisations are able to use this framework to design and adjust their units to conform the exact customer needs. This paper introduces and explains a new idea of measuring value added along the supply chain from a collaborative perspective. The extended model is adapted from our previous model and from balanced scorecard model. It provides a tool to measure tangible and intangible value between partners.     

The Association Between Partner Enhancement and Self‐Enhancement and Relationship Quality Outcomes

The purpose of this research was to understand in greater detail, using 2 samples (Study 1 N = 4,881 heterosexual couples; Study 2 N = 335 heterosexual couples who completed the Relationship Evaluation Questionnaire), how partner or self‐enhancement patterns differentially influence relationship outcomes. A multivariate analysis of covariance was conducted comparing 4 outcome measures for different couple types in which individuals rated the partner higher, the same, or lower than they rated themselves on affability. Couples in which both individuals perceived themselves as more affable than the partner experienced poorer results on the relationship outcome measures, whereas couples in which both individuals perceived the partner's personality as more affable than their own experienced more positive relationship outcomes. Additional analyses with structural equation models demonstrated the consistent influence of enhancement measures on relationship outcomes for cross‐sectional and longitudinal samples.

过度掺杂的La1-xAgxMnO3室温磁电阻研究

对采用溶胶凝胶法制备的不同Ag含量的La1-xAgxMnO3样品进行了研究.观察到Ag的名义含量x为0.3和0.65的样品表现出显著的室温磁电阻,在1.8 T的外场下磁电阻(外加磁场后的电阻和未加磁场的电阻差值比上未加磁场的电阻值)分别达到-23.0%和-22.7%,接近实际应用要求.对其成因进一步分析后发现,在两种不同Ag含量的样品中出现的显著室温磁电阻效应,其形成原因并不相同.
