The invention can increase the production rate because of fast heating rate and cooling rate obviously.
本发明由于升温速率和降温速率很快，可以明显提高生产速率。
The results show that the temperature reduces fast at first stage, because of the larger difference between blade and air. Then, the temperature reduction rate decreases slowerly, in cooling process.
结果表明：初始时刻叶片表面和环境温差较大，温降较快，随着冷却过程进行，温降速度变缓；
