Analysis of the Variations of Body Build of Middle-and Old-aged and Research on the Prototype

The characteristics of body build of middle - and old -aged women and its rule of variations as well as the basic sizes of various parts are discussed. All these are based on the body measurements of this age group, and also on the statistical studies of the measurement data. By setting the regression equation, the calculating formulae of various control parts are obtained, thus establishing the prototype of this age group for women.

翠馨苑小区地基处理

通过对几种地基处理方案约分析比较，翠馨苑小区最终采纳了以石粉田填为主的地基处理方案。石粉成分以长石和石英为主，是一种化学稳定性好、抗风化能力强、无腐蚀、易夯实的材料。用石粉做垫层进行地基处理，加大了上覆非液化土层厚度，使处理后的地基可不考虑液化影响，强度高、压缩性低、消耗上部附加能力强，就地取材、造价低、施工方便，既满足了设计要求，又经济合理。

为了扩大 ２００ ＭＷ核供热堆（ＮＨＲ－２００）的应用范围并改善其经济性，初步探讨了在ＮＨＲ－２００的技术基础上，发展热电联供小型反应堆的可能性。提出了核反应堆实现热电联供的几种可能方案，并用编制的计算机程序对其效益进行了分析；提出了小型热电联供沸水堆ＣＲ－２００的一回路方案设计，用最佳热工水力估算程序ＲＥＴＲＡＮ－０２和编制的蒸发器设计程序对ＣＲ－２００作了初步的一回路稳态热工设计和稳定性分析。结果表明，以ＮＨＲ－２００为基础并作一些改进，有可能发展成为小型热电联供沸水堆ＣＲ－２００，该堆具有比低温供热堆ＨＲ－２００更好的经济性。     

Simulation Modeling by Fuzzy Nets

Fuzzy technology is a newly developed discipline based on fuzzy mathematics. In the recent years, it has been successfully applied into many areas, such as process control, diagnosis,evaluation, decision making and scheduling, especially in simulation where accurate mathematical models can not or very hard be established. In this paper, to meet the demands of fuzzy simulation, two fuzzy nets will first be presented, which are quite suitable for modeling the parallel or concurrent systems with fuzzy behavior. Then, a concept of active simulation will be introduced, in which the simulation model not only can show its fuzzy behavior, but also has a certain ability which can actively perform many very useful actions, such as automatic warning, realtime monitoring, simulation re-sult checking, simulation model self-adapting, error recovery, simulating path tracing, system states inspecting and exception handling, by a unified approach while some specified events occur. The simulation model described by this

中瑞西北科学考查团组建中的争议

1927—1935年间的中瑞西北科学考查团在组建过程中一波三折,充满争议与矛盾,地质调查所从最初的主角,变成局外人,其中的过程、原因颇有耐人寻味之处。文章考察了争议的过程和结果,分析了争议产生的原因,认为:此次争议及科考活动,使更多的人对中外科学合作有了更客观、积极的认识;由于中国学术界未能充分相互信任与合作,使学术成果受到一定局限和不必要的损失。虽然此次中瑞西北科学考查团组建中的争议,是近代中国科学发展史中一个特殊时期内发生的特殊案例,但它所反映出的问题却具有一定的普遍性,甚至超出了时间的局限而值得一再地反思和解读其中的内在含义。     

Pilot Study on Drinking Water Advanced Treatment by GAC-MF System

The pilot pedomance of the combined GAC-MF membrane process for drinking water advanced treatment was described. In the process of GAC adsorption, under the conditions of 20min HRT and 6 m/h filtration rate, the removal efficiencies of UV254 and trichloromethane could reach 40% and 50% respectively and the UV254 and trichloromethane in system effluent was less than 0.015cm^-1 and 5 μg/L respectively. Inthe post MF membrane process, MF membrane effectively retained the particles and bacteria in raw water. The effluentturbidity was less than 0.2 NTU and no bacteria were detectedat all in permeate. A computer-controlled system was employedto control this system. The mcmlrane operating parameters of backwash interval, dtration and flux were studied. The backwash interval of 10-min, 20-min and 60-min wasresearched respectively, and the variation of trans-membrane pressure was also analyzed. Comequently short backwash interval was recommended under the same water consume.
