Shaking Table Test on Out-of-Plane Stability of Infill Masonry Wall

The behaviors of infill wall in earthquakes show that infill masonry walls,which are used as nonstructural elements of concrete frames,are vulnerable when they are subjected to earthquake.In order to achieve an optimal antiseismic behavior,or even stability,two methods of connection are investigated.The shaking table tests,with 1:3 scale walls of two-storey model subjected to horizontal earthquake loads,were carried out to investigate the out-of-plane behaviors with different connections between walls and beams.The test results show that the connection methods employed between walls and beams have a significant effect on the out-of-plane stability of infill walls.The walls bound by bars with the beams perform better than those with inclined bricks without gaps.     

狭义相对论中各变换式的重新推导及合理性分析

鉴于狭义相对论的不自恰性,对整个理论体系存在的两处失误进行了修正,使之在符合现有实验的基础上,与经典理论达到融合。首先指出导出洛仑兹时空变换式的原始数学模型存在缺陷,对其修正后,重新推导出了新的洛仑兹时空变换式。其次对力的定义进行了严格分析,据此导出两惯性系间的力变换式,简洁明了。对比新旧变换式(推论),阐述了旧变换式存在的不合理之处和新变换式的合理性。     

加速度传感器测量自行车运动能耗的效度研究

用加速度传感器测量自行车运动能耗,结果显示：佩戴在脚踝处的加速度传感器记录的各个方向的counts平均值明显大于佩戴在腰部的counts平均值（P〈O．05）;运用FreedsonVM3计算模型计算的腰部预测MET平均值显著低于标准MET平均值（P〈0．05）,而脚踝部预测MET平均值则显著大于标准MET平均值（P〈0．05）;本研究推导的模型计算的预测MET平均值与标准MET平均值基本一致,没有显著性差异。

Schooling in times of acceleration

Abstract

Modern societies are characterised by forms of acceleration, which influence social processes. Sociologist Hartmut Rosa has systematised temporal structures by focusing on three categories of social acceleration: technical acceleration, acceleration of social change, and acceleration of the pace of life. All three processes of acceleration are closely linked to processes of internationalisation and globalisation. Given this background, developments in the context of school education are analysed in this article, paying special attention to the question of which areas of academic learning the categories of social acceleration affect and whether internationalisation and globalisation speed up these processes. The analyses show that effects of globalisation in the fields of management, market, and performance on education are closely linked to social acceleration.     

加强审计监督,促进廉政建设

经济越发展，越需要审计。审计在改革开放中发挥着越来越重要的作用。只要坚持依法审计，为严肃执法提供有力证据，就会更加有利于规范经济行为，促进党风廉政建设。     

城市汽车道路排放特性试验与分析

通过对20万、30万、40万公里行驶里程的同型号的汽油小轿车进行车载尾气排放测试,数据表明,CO,NOx,HC的平均排放因子随汽车行驶里程的增加而升高,分析了在低、中、高匀速状态下,汽车排放随速度和行驶里程变化的规律,以及汽车加速度对汽车排放的影响.     

用自制圆锥摆与Spss标定重力加速度

用直流电源驱动自制圆锥摆实验系统,使小钢球做较为稳定的圆锥摆运动,可显著减弱小钢球的滞后现象,从而可忽略空气阻尼等因素的影响,使得对圆锥摆周期的测量更为准确。由测量原理及不确定分析,结合测量数据,用Spss分析得出长度综合量（A）与圆锥摆运动周期的平方（T2）呈线性关系,由此标定出重力加速度,并用置信概率为95%的不确定度对实验结果进行了分析与评价。
