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.

本文提出了一种新的均质核化沸腾爆炸模型。应用该模型可以正确解释和理解（1）线性升温超过10^8 K/ s，（2）液体与高温表面接触，（3）100 MW/ m^2量级高热流密度脉冲加热等3种不同快速加热方式引起的沸腾爆炸<-6>。它的传感器使高温表面液淬冷却曲线与我们提出的反解有了很大的改进。
