As metastable atoms deexcite, the vapor velocity and temperature increase, the peak value of the velocity distribution function shifts rightward, and the half width increases.

亚稳态原子消激发，使蒸气宏观速度增加，温度增加，所以使速度分布函数峰值右移，半宽度增加。

The results show that the temperature of the smaller char particle is close to the bed temperature, and there also exists a peak value for the burn-out time of char particles versus their diameters.

结果表明：粒径越小，其温度越接近于床内环境温度，而且燃尽时间随粒径变化的曲线将出现峰值。

With preheating temperature enhancing, the peak value also increase, but cooling velocity decreases, resulting from the decrease of heat conductivity of sample lower surface.

随着预热温度的提高，电阻峰值也相应增大，但是样品下表面的热导出率下降，冷却速度下降；
