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。

To make accurate temperature measurements with thermocouples, the reference junction temperature must remain constant. If it varies, suitable compensation for these variations must be provided.

要用热电偶实现精确的温度测量，参考端温度必须保持恒定；如果会变化，必须提供这些变化的适当补偿。
