The results indicates that doping and temperature of heat treatment greatly affectes the structure of thin film and its size of crystalline grain, thereby, influences its conduction and sensibility.
In polycrystalline samples, the intermediate-frequency mechanism is interpreted as the grain-boundary conduction mechanism.
而矿物多晶中间频率段的导电机制由颗粒边界所引起。

Analyzing the sintering theory of nano material and the heat conduction theory of laser machining, the mathematic model of grain size growth of nano material in laser irradiation was built.
