A new model has been developed to analyze boiling explosion due to homogeneous nucleation. Boiling explosion caused by three different types of rapid heating such as(1) linearly temperature rise higher than 10^8 K/ s,(2) contact of liquid with high temperature surface(3) pulse heating of high heat flux of 100 MW/ m^2 level, can be explained and understood correctly by applying the new model.A temperature sensor with high response time of 10^<-6> second is newly developed. Its sensor makes it possible that a cooling curve obtained by quenching high temperature surface with liquid is much improved together with inverse solution developed by us.

开发了一种新模型来分析均匀成核引起的沸腾爆炸。 (1)线性温升高于10^8K/s、(2)液体与高温表面接触(3)100MW/次高热流脉冲加热三种不同类型的快速加热引起的沸腾爆炸m^2级别，应用新模型可以正确解释和理解。新开发了10^<-6>秒高响应时间的温度传感器。其传感器与我们开发的逆解一起使得通过液体淬火高温表面获得的冷却曲线得到很大改善。
