It was shown that the dynamic effect of the temperature and thermal stress of piston must be considered during thermal shock.
计算结果表明：活塞在热冲击期间表现的温度及热应力的动力学效应是必须加以考虑的。

The high energy pulse laser was used to radiate lead zirconate titanate (PZT) piezoelectric films. The effect of the laser thermalshock on the properties of the films was investigated.
The R-curve and thermalshock resistance properties are improved and the transformation effect are strengthened by the surface compressive stress effect.
