Based on cylindrical shell theory, the calculating formulas of circumferential pressures, circumferential stresses and pressure influence height on chimney tube generated by radial pressure are obtained.
用圆柱壳理论导出了径向压力在筒壁中产生的环向压力、环向压应力、压力影响高度的计算公式,环向压应力呈曲线分布。
Scene measurement of strengthening process shows the maximum of circumferential compression stress produced by chimney wall s concrete can reach the value of 1.
在钢筋混凝土烟囱裂缝加固工程中采用了无粘结钢绞线预应力环箍,对加固过程进行了现场测试,经预应力环箍加固后的烟囱筒壁中建立的环向压应力在环箍处最大,其值约-1。
Adopting the questionnaire method (developed by researcher), the present study focused on the source and characteristics of school stress of middle school students.
本研究在自编问卷的基础上,探讨初中生校园压力来源,及压力感的特点。
since 1978 , that philips firstly studied the school stress systematically , It has became a heated topic of the acadamic study and caused wildly attention of the world to analyze the reasons of problem behaviors, like study-detestation、ragging、indulgement in internet,etc.
校园是一种特殊的社会环境,校园生活是儿童社会心理压力的重要来源,自1978 年Phillips 首开校园压力系统研究之先河以后,从校园压力的角度分析学生厌学、欺负、网络迷恋等问题行为产生的原因,探讨有效预防和教育干预的途径和方法,成为日益受到学术界广泛关注的热点问题。
