中国数学史断代研究的一项新成果：—《明清数学史论文集》简介

本文简介梅荣照主编的《明清数学史论文集》一书，对中国数学史开展断代专题研究，是我国数学史界继承并发展李俨、钱宝琮、严郭杰先生研究成果的宏大计划，持续近三十年，历来为国际科学史界所重视，文集收入论文15篇、附录2篇，其中严敦杰先生遗作7篇，本文对15篇论文逐一作了简介。     

女性命运的不同阐释--比较《玉米》和《麦穗》

毕飞宇的《玉米》和迟子建的《麦穗》都以书写女性人生为主要内容,但由于作家自身经历、人生观念的差异,两篇题材相似的作品对女性命运的阐释有很大不同,前者描述的是一个权欲的悲剧,后者则用美好的人性温暖了女主角原本走向黯淡的人生。

The Challenging Topics and Future Directions of the Research in Limnology and Watershed Sciences

Based on reviewing the problems in limnology and watershed sciences in meeting the national demands and the development of theories and methodology, this paper proposed some challenging topics to the sciences, covering the process of lake evolution and the quantitative analysis of human impacts, in -lake nutrient cycling an biogeo-chemical process, the process and mechanisms of material flow in lake-watershed system, digital watershed and the modeling of the surface process of lake -watershed, and ecosystem health and scientific management of lake-watershed.     

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.     

基于Elmore模型的Steiner树问题的求解

建立了一种求解基于Elmore延迟模型的Steiner树问题的遗传算法。针对Steiner树问题的特点,在引入一种新的具有自适应性的杂交概率和变异概率的基础上,提出了面向Steinet树问题的遺传算法和一种构造染色体的新方法。提供了遗传算法的结构并讨论了遗传算子。分析了基于时间和空间的算法复杂性。     

从《红楼梦评论》到《红楼梦辨》--王国维、俞平伯评红的贡献与不足

在红学史上,王国维和俞平伯都有杰出的贡献,王国维的《红楼梦评论》和俞平伯的《红楼梦辨》都具有里程碑的意义。《红楼梦评论》和《红楼梦辨》二者的承继关系尤为明显,前者对后者具有很大的启发作用,而后者不仅对前者有所继承,也有重要发展,因此可以说,新红学的产生与王国维的影响是分不开的。
