If the valve body material can be welded, but very different thermal expansion coefficient, or changes in operating temperature range of a larger thread junction closure weld must be honey.

如果阀体的材料是可以焊接的，但膨胀系数差异很大，或者工作温度的变化幅度范围较大，螺纹连接部必须进行蜜封焊。

Transistor thermal spectrum, as a new method, different from the commonly infrared thermogram, is introduced to characterize the non-uniform property of the junction temperature distribution.

晶体管热谱是表示晶体管结温不均匀性的一种与热像图不同的新方法。
