液态金属实验回路(LMEL)的总体设计和运行

液态金属实验回路（ＬＭＥＬ）是国内唯一用于聚变堆磁流体动力学（ＭＨＤ）效应和材料相容性研究的大型实验装置。与国外同类先进的装置相比，回路流程和运行方式均有重大改进，使其更先进、安全并具有多功能。回路运行分为两个阶段：第一阶段以钠－钾低共熔合金（２２Ｎａ７８Ｋ）为工质，研究ＭＨＤ效应，ＬＭＥＬ的最大哈特曼（Ｈａｒｔｍａｎｎ）数Ｍ和相互作用参数Ｎ分别为０．７５×１０４和２．５×１０４；第二阶段以液态锂为工质，研究结构材料与锂的相容性，最高温度和流速分别为５２０℃和１．３８ｍ／ｓ。

An improved outer pipe method for expansive pressure measurement of static cracking agentsOA

Static cracking agent(SCA) is actively investigated as an alternative to explosive blasting for rock breakage due to its immense expansion property. SCA can eliminate the negative effects of shock, noise and harmful gases encountered in explosive blasting processes. Accurate measurement and deep understanding of the expansive properties of SCAs are important in their industrial application. An improved outer pipe method(OPM), termed the upper end surface method(UESM), is proposed in this paper t...     

循环流化床风室的压力脉动特性分析

针对直径为0.205m,高度为7m的冷态高密度循环流化床(CFB)试验台,在表观气速为6.3m/s的条件下,借助小波理论对不同循环流率、不同出口结构的压力脉动特性进行了分析。结果表明:不管是高密度条件下还是低密度条件下的压力脉动,均属于低频脉动,脉动幅度为0~12.5Hz;在相同的出口结构和同一表观气速下,随着循环流率的增加,风室的压力增加,压力脉动的幅度也增加;在同一表观气速和相同循环流率下,Г型突变出口结构的风室压力和压力脉动幅度的增长速率均比C型光滑出口结构的大。     

Yielding, authoritarianism, and authoritarian ideology regarding groups.

This investigation was prompted by Asch's (1952) discussion of the personal and social significance of yielding to group pressure. For the person, yielding requires the inhibition of overt and perhaps implicit responses to objective situational requirements. For the group, malignant processes may arise and develop, unchecked by those members in whom goals of personal security predominate over group goals. In the present study, the view was taken that both meanings of yielding are assigned positive value in two separate ideologies concerning the group-individual relation. One of these is termed "conformity" and the other is "rugged individualism." In the study, group pressure was simulated by announcing bogus group judgments to small groups of Ss whose apparent task was to match one of three lines of variable length with a standard line. Questionnaires were used to measure variables, which were: the ideology of conformity (IC), the ideology of rugged individualism (RI), ethnocentrism (E), and authoritarianism (F). The questionnaires were administered to 91 college students, both day school and evening. It was found that the correlation with the F scale was .48 (P
