Thermal shock is a variation in temperature which causes tension in a material. It frequently causes breakage in the material, and is most common in brittle materials such as ceramics.
This is a process that takes place abruptly when there is a sudden variation of temperature, either from hot to cold or vice versa. It is most common in materials that are structurally weak as well as those which offer a poor heat conductivity.

热冲击是温度的变化引起材料的张力。它经常导致材料的断裂，在脆性材料如陶瓷中最常见。

这是一个突然发生的过程，当有一个突然的温度变化，从热到冷或反之。这在结构脆弱的材料以及导热性差的材料中最常见。
