乙醇透析发酵耦合过程研究（Ⅰ）

设计了乙醇发酵与膜透析耦合系统并进行了试验研究．结果表明，该过程可减少产物乙醇对发酵的抑制作用，膜透析系统的乙醇总量比对照组提高２０％～８０％，基质转化率提高３０％～８０％．

针对非统计专业统计学教育目前存在的问题,阐述了提高对统计学重要性的认识是保证统计教学效果的前提;统计学教学环节的改革是提高教学效果的重要保证;统计教师的业务素质是提高统计教学效果的关键。     

中国与俄罗斯经济转轨比较

经济转轨的基础决定了中国与俄罗斯的经济转轨方向的不同，产权改革的效率决定两国经济转轨的成效。通过两国经济转轨的比较，文章认为有三个方面的深刻经验教训特别值得我们重视，即经济转轨必须高度重视政府的作用、产权私有化并非提高效率的充分必要条件、产权制度的变迁具有演进性和不可复制性。     

西方歌剧Leitmotif(主题)技巧的起源与发展

Leitmotif被广泛地运用在西方歌剧中并起着非常重要的作用。本文论述了leitmotif的起源与发展。早期Leitmotif它的特征是反复出现但是变化不多。后来韦伯发展了这一技巧。他不仅在leitmotif再现时增加了和声和节奏上的变化,而且还用leitmotif将歌剧各幕之间联系起来,起到了贯穿的作用。德国作曲家瓦格纳将leitmotif技巧的运用提到了最高的水平。瓦格纳创造性地将多个leitmotif交织在一起运用,形成一个大的音乐网。并用此网从始至终与剧情紧密配合,使其成为作品必不可少的主体。从而打破了歌剧原有的固定型式,为歌剧的发展写下了重要的一页。     

Small Town in Mass Society Revisited1

Abstract The case study of a small New York town that dramatized the thesis that the secular expansion of macro forces—urbanization, industrialization, bureaucratization—has permanently reduced the autonomy of all small communities is an example of a special type of discovery/persuasion strategy in the social sciences: the “opposition case study.” In contrast to the more rigorous “competitive test” or the atheoretical “negative case,” opposition case studies confront the dominant perspective with a qualitative illustration of a new theory in the context of a zero-sum game. When they are successful, opposition cases meet four criteria: the dominant view is immediately rendered obsolete; the origin of the new idea supports its plausibility; the new perspective is shown to be testable; and the new perspective quickly generates new lines of research. Small Town in Mass Society meets the first criterion, and may have been heuristic, but its probable origin in populist ideology undermines its testability.     

当代印度南部婆罗门状况的个案分析——以奈保尔《印度:百万叛变的今天》为例

当代印度社会正发生着极大的变动,社会各阶层都在极力维护固有地位和宗教传统的稳定,并极力在这种变动中争取着自身社会利益的最大化。其中,南印度婆罗门种姓在逐步丧失传统的各项特权和优势地位的同时,也在努力适应、应对当代社会的新变化和新挑战。英国作家V.S.奈保尔的《印度:百万叛变的今天》一书提供了较为翔实、客观的口述史资料。以书中生活在孟买、班加罗尔、马德拉斯、加尔各达等南印度城市中的当代婆罗门阶层作为个案,可探究出其面对传统社会生活中的各个层面发生变动时的态度与应对及个体内在的深层原因,并在一定程度上考察社会变动与文化传统之间的互动关系。     

WEIGHTED SUMS OF NEGATIVELY ASSOCIATED RANDOM VARIABLES

In this paper, we establish strong laws for weighted sums of negatively associated (NA) random variables which have a higher‐order moment condition. Some results of Bai Z.D. & Cheng P.E. (2000) [Marcinkiewicz strong laws for linear statistics. Statist. and Probab. Lett. 43, 105–112,] and Sung S.K. (2001) [Strong laws for weighted sums of i.i.d. random variables, Statist. and Probab. Lett. 52, 413–419] are sharpened and extended from the independent identically distributed case to the NA setting. Also, one of the results of Li D.L. et al. (1995) [Complete convergence and almost sure convergence of weighted sums of random variables. J. Theoret. Probab. 8, 49–76,] is complemented and extended.
