Water has a variable coefficient of expansion.

水的膨胀系数是可变的.

After jointing, coefficient of expansion leads to remain force.

接合后存在残余应力起因于材料的热膨胀系数。

The soldering glass has a rather low coefficient of expansion as well as low sealing temperature.

然而，通常热膨服系数高的封接玻璃软化温度低，而热膨胀系数低的软化温度偏高。

If there is a large difference in the coefficient of expansion, there will be cracks in the ceramic layer or the phenomenon of exploding porcelain in the alternating heat and cold.

如果膨胀系数相差较大，在冷热交替的时候就会出现瓷层裂纹或爆瓷现象。
