乙醇三维内微肋热管的传热性能

采用实验研究的方法对三维内微肋热管的强化传热特性进行研究，首次报道了以乙醇为工质的三维内微肋热管的传热性能。在实验范围内，与光管相比，竖直放置时，沸腾换热系数可以提高98％—190％，凝结换热系数可以提高76％—178％。三维内微肋结构能够同时明显地强化热管的沸腾换热与凝结换热，可以有效地减小热管的内热阻。

Emergent Property in Macromolecular Motion

In this paper, the model of inverse cascade fractal super-blocks along one direction (in the positive or negative) in the 3-dimensional space is developed to describe the self-similar motion in macromolecular system. Microscopically the cohesive and dispersed states of the motion blocks are co- existent states with vastly different probability of occurrence. Experimental results and theoretical analysis show that the microscopic cohesive state energy and dispersed state energy of each motion block are respectively equal to the macroscopic glassy state energy kTg and molten state energy kTm of the system. This singularity unveils topologically the non-integrability, mathematically the anholonomy, and macroscopically the emergent property. This singularity also reveals that the glass, viscoelastic and melt states are three distinct emergent properties of macromolecular motion from a macroscopic viewpoint. The fractal concept of excluded volume is introduced to depict the random motion at various scales in     

Impact of the Small Town Construction on Original Inhabitants in the Three Gorges Reservoir Area--A Case Study in Lishu Village, Changling Town, Chongqing Municipality, China

Based on the five-year long dynamic tracking and investigation of the peasant households of the Lishu village, the influences by small town construction on the economy and employment of the original peasant households are discussed. On the one hand, small town construction plays a positive role in adjustment of the industrial structure of the original peasant households and in the transfer of their employment towards non-agricultural industries. On the other hand the economic growth of the original peasant households is not so well sustainable, and is so fluctuating. Moreover,the unbalance of income distribution of the said households has been furthered, and small town construction has made the existing labor surplus of the original peasant households more serious, particularly the women labor surplus.     

三峡库区开县坡地稳定性综合评价

将开县自然条件与社会经济发展程度近似的乡镇划成5个片区，再将各参评因子的调查数据通过数理分析统计处理。得出各片区坡地稳定性综合评价指数，并进行评价。其成果对三峡库区及长江上游的生态环境建设和农业结构调整均有积极指导意义。     

试论孙中山三民主义的社会作用

在三民主义的指导下，中国人民终于推翻了清朝反动政府，结束了中国两千多年的封建专制，建立了资产阶级民主共和国——中华民国；新三民主义极大鼓舞了全国人民革命热情，在国共两党领导下，沉重打击了北洋军阎反动统治；新三民主义为中国共产党人、中国各族党派所坚持、所发展、所实现，终于推翻了帝国主义、封建主义、官僚资本主义反动统治，建立中华人民共和国。     

关于非平稳过程处理的几个注解

研究了非平稳的含义、非平稳随机过程的等效和幂律过程处理等几个问题．首先，阐述了非平稳存在两种理解，一种是针对确定性过程，另一种针对随机过程，二分别适用于信号处理和随机动力学计算两种情形．其次，证明任何一个非平稳过程都可以用可数个调制非平稳过程来模拟或等效．然后，指出幂律过程为平稳过程，而非献中所声明的非平稳过程．最后，论述了通过理想滤波器概念可以将幂律过程转变为各态历经过程．     

平面四杆机构极位夹角的取值范围

对平面四杆机构极位夹角的定义作了较确切的表述，并推导出了曲柄摇杆机构、曲柄滑块机构和摆动导杆机构极位夹角的取值范围。     

胶体晶体及三维有序多孔材料的制备

以粒径为80～320nm的单分散苯乙烯／苯乙烯磺酸钠共聚微球为原料，采用一种全新而简单的制备高度有序胶体晶体模板的方法，利用静电相互作用、表面张力以及蒸发过程中的离子扩散等作用在液面形成了不合溶剂的高度有序的胶体晶体．将溶胶-凝胶前驱液在毛细效应作用下渗入胶体晶体间隙，待前驱液固化后，经煅烧去除苯乙烯微球，制备出了具有三维有序结构的多孔材料——倒置蛋白石．
