水－仲丁醇－碳4三元体系8MPa时的液液平衡

在国内首次建立的一套温度高达３５０℃，压力直至２０ＭＰａ的高压液液相平衡测定装置上，测定了水－仲丁醇－碳４三元体系在８ＭＰａ和４０３．１５，４２３．１５，４４３．１５Ｋ时液液相平衡数据。采用修改的Ｒ－Ｋ方程对此数据进行了理论关联。关联结果与实验数据一致。     

A ROBUST DECOMPOSITION OF LINEAR PROGRAMMING USING A GOAL-PARTITIONING METHOD

The Dantzig/Wolfe linear programming decomposition algorithm has had important economicinterpretations as well as a widespread impact on solving large scale linear programming problem.Inthis paper we consider a similar underlying structure,where however there is only one couplinginequality or equation.With this simplification,we demonstrate how to achieve an equitable partitionof the overall coupling resource to individual subproblem constraints through a simple iterationprocedure which appears to be very efficient.     

The behavior of the homozygous and heterozygous sub-types of rats which are genetically-selected for diabetes insipidus: A comparison with Long Evans and Wistar stocks

Several aspects of spontaneous and conditioned behavior (food and water intake, locomotion and emotionality, passive and active avoidance acquisition and retention) of standard (albino and pigmented) rats, and rats heterozygous (HEDI) and homozygous (HODI) for diabetes insipidus, are reviewed. As would be expected, HODI rats have been repeatedly found to consume far more fluid than either HEDI or control rats. Pigmented rats appear to be more active than albinos. HODI rats exhibit less marked emotional responses than do control rats, among which the pigmented ones exhibit the highest emotionality. Light aversion is more evident in albino than in pigmented rats. No differences are found among HEDI, HODI and normal Long Evans rats. It is quite difficult to provide a clear-cut statement concerning inter-strain differences in passive avoidance behavior, possibly because of the variety of techniques employed. In any case, HODI rats do not perform worse than normal controls do. In one-way active avoidance paradigms, pigmented rats perform better than albinos, and the performance of HODI rats does not differ from that of controls. In two-way avoidance paradigms, albinos appear to outperform pigmented rats. Once again, there are no obvious differences between HODI and control animals.In addition to indicating that HODI rats may actually be less emotional than the other groups of rats reviewed here, the studies described once again fail to confirm the previously alleged functions of vasopressin in memory consolidation.     

水蒸汽在调湿剂中有效扩散系数的测定

采用“单粒柱”新技术，测定了水蒸汽在粒状调湿剂中的有效扩散系数。以不同粒度、不同种类载气、不同吹扫气速进行测定，结果一致。表明：水蒸汽在粒状调湿剂中的扩散为粒子内扩散控制。以本法测定和对比了不同调湿剂中水蒸汽的有效扩散系数。     

水泥处理的沉积淤泥膨胀试验及其矿物机理分析

为研究经过水泥掺合处理的河道沉积淤泥作为路基填料的膨胀性能，对不同初始含水量（质量分数分别为90％，130％和170％）的淤泥经不同掺合比（按湿质量计分别为9％，11％和13％）的水泥处理后形成的多种不同的水泥土试样进行了为期一个月的初次膨胀试验及试样干燥三个月后重新浸水的二次膨胀试验。试验结果表明试样的初次膨胀值很不显著，但二次浸水膨胀试验表明试样的总膨胀量有增大的趋势。试样的X射线衍射分析从矿物形成方面解释了水泥土膨胀性能的内在机理。     

吊舱式推进装置水动力性能试验研究

对吊舱式推进装置进行了多方案的模型试验研究，考察了串列式吊舱推进装置前后桨的负荷匹配及初始相位角的影响。空泡水筒敞水试验结果表明，无论双桨串列式或单桨拖、推式吊舱推进装置，由于吊舱影响使螺旋桨效率均比常规桨有所提高；但若计及吊舱阻力则吊舱推进装置的系统效率有所下降。可以预见，吊舱式推进装置因其众多的优越性而具有广阔的发展前景。     

人性假设与企业人力资源管理

人性假设是许多社会科学领域研究的出发点 ,企业也常常从自己的人性假设出发形成企业人力资源管理的理念。基于不同的人性假设 ,中国古代哲学、近现代西方经济学和管理学分别提出了对社会治理和企业治理的看法。在总结与分析的基础上 ,我们提出一种“混沌人”的假设。
