透湿过程中织物的润湿和散湿作用

采用蒸发和吸湿法测量多种织物的透湿速率，并且仔细研究用蒸发法时，织物润湿程度在透湿过程中的变化，发现织物在透湿过程中的润湿和放湿，以及织物的表面性状是影响其放湿速率的非常重要的因素。     

非对称度量空间上不动点定理

提出建立在非对称度量空间之间的上收缩映射和下收缩映射的概念.考虑到非对称度量的不对称性,进一步定义了非对称度量空间到自身映射的左不动点和右不动点.最后,给出了非对称度量空间上的两个不动点定理.     

Functional magnetic resonance imaging of amphetamine craving

The aim of this study is to identify the brain activity associated with amphetamine craving for understanding the neurobiology of addiction by watching pictures of happy, sad or amphetamine. Brain activity was measured in 12 amphetamine addicts and 12 healthy subjects by fMRI while the subjects watched pictures designed to elicit happy feelings, sad feelings, or the desire to use amphetamine. The result demonstrated that amphetamine cues led to abnormally high cingulate and low frontal lobe activation in amphetamine addicts, who showed abnormalities in affect-related brain activation.     

基于可拓-集对的经济策略生成方法

提出经济策略的概念，经济策略不是最优策略，经济策略也不等同于满意策略。经济策略的生成是决策科学研究的一个重要内容。以可拓方法和集对分析为基础，提出一种适合于生成经济策略的新方法——基于可拓一集对的经济策略生成方法，并以赈灾物资的管理为例．介绍该方法的应用步骤。     

Development of Full Automatic External Welding Machine for Annular Welds of Pipeline

To meet the demands of rapid development of pipeline constructions in China, a complete set of full automatic external welding machine for annular welds of pipeline and welding procedure have been developed thereof. The system has been applied in the “West-East Pipeline Project” and its performance is proven. With this welding machine the welding parameters can be either preset before or adjusted in real time during the welding process, which avoids the blemishes of same type domestic and international products. Thus it is best propitious to in-situ construction conditions and workers‘ technical level in China. In this article the development of mechanical and control systems of this product is introduced and typical welding procedure parameters are provided.

APPLICATION OF BORON MODIFIED SILICA SOL ON RETENTION AND DRAINAGE

INTRODUCTIONRecently with the high speed, large-scale develop-ment of papermaking, in the manufacture of paper and paperboard conventional single and dual reten-tion and drainage systems cannot obtain satisfying re-tention and drainage. So in 1980 microparticulate systems appeared. Because of its superiority such as good retention effectiveness on fine and chemicals, improving drainage and paper formation, reducing waste water and enhancing the concentration of white water for good recover…     

籽瓜植株(地上部)的生长发育规律

对内蒙古地区有代表性的四个籽瓜品种植株(地上部)的生长发育进行了研究．结果表明：内蒙古籽瓜的全生育期为92-101d，籽瓜植株的生长发育可分为发芽期、幼苗期、伸蔓期和结果期，结果期分为前期(开花座果期)、中期(果实膨大期)、后期(种子成熟期)．发芽期、幼苗期以叶为生长中心，伸蔓期、结果前期以茎为生长中心，进入结果中期以果实为生长中心不同生育分期长短的差异主要表现在结果中期的差异上．     

广义不确定原理对一般静态黑洞熵的影响

把广义不确定原理引入黑洞熵的计算,采用薄膜brick-wall模型,对一般静态黑洞外部标量场的熵进行了计算,得到了熵计算公式.应用该公式结果表明,可以得到已知所有静态黑洞的Bekenstein-Hawking熵.作为比较和进一步研究,对视界面上的二维膜的熵进行计算,可以更方便和一般性地得到熵与视界面积成正比的结论,该讨论可直接表明黑洞熵就是其视界面上的量子态的熵.与原始brick-wall模型不同的是,这一结论是有限的,计算中无需引入截断,且小质量近似也可以避免.
