简介：要满足轴承性能要求，以淬火硬化为目的的热处理是不可少的工序。热处理工序中所消耗的能源占轴承制造工序总能耗的25％左右。在当今世界，迫切需要应对地球变暖为首的环保问题，轴承的热处理工序也不例外，对降低环境负担的要求非常严格。对环境做出贡献，也就是节能，要求采取的对策是：热处理工序的高效化；从整个工程角度，以降低能耗为目的防止热处理变形的对策。本文围绕轴承典型的热处理方法及节能这一关键问题，简要说明热处理的高效化与低变形热处理技术。1轴承的热处理方法

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。

简介：宝宝4个月后，就要开始考虑添加蛋黄。这时候宝宝从妈妈那里得到的铁已经被消耗得差不多了，必须通过吃富含铁质的食物进行补充。蛋黄含有丰富的铁质、蛋白质、脂类，又容易消化，经常被妈妈们选择作为最早添加的蛋白质类辅食。
