Normally, coefficient of convective heat transfer is gotten through experiments which is heating testing tube by electricity and computed through Newton coolinglaw.
通常，对流换热系数是在实验中以电加热试验管壁面后根据牛顿冷却定律计算得来的。

The influence law of cooling effectiveness by flow rate of seal oil at a fixed temperature was got.
通过计算得到了一定温度下封油流量对密封冲洗冷却效果的影响规律。
3
A concept about critical cooling thickness of mirrors has been suggested, and a scaling law of multi-pulse accumulative effects has been obtained.
