简介:摘要:日常设计和制造中,经常发生一些设计人员或制造人员对标准规范提及的压力容器方面的热处理相关情况模糊不清、以及理解错误的事情。给设备核价、图纸提要求、制造中的热处理方案处理等造成极大的困惑。本文从压力容器所要求的热处理原理方面进行谈诉,结合GB标准,给相关设计、技术人员提供一盏明灯。并将目前的热处理方法进行对比。避免实际制造中走弯路。
简介:摘要 : 班主任工作很 繁琐,特别是突如其来的偶发事件,可能搞得班主任措手不及,十分恼火。但是咄咄逼人的训斥,尖酸刻薄的嘲讽,横暴野蛮的体罚,并不能显示出教育的威力,反而会暴露出班主任心理素质脆弱、情感素质浅薄。很多有经验的班主任能将问题消灭于萌芽状态,防患于未然,即使遇到突发事件,也能泰然处之、临阵不乱,在一颦一笑或娓娓而谈中使问题得到妥善解决。
