Therefore the object is to produce the phenomenon of thermal expansion and contraction of the premise of thermal stress.

因此，物体热胀冷缩现象是产生热应力的前提。

youdao

At least one flexure joint is provided in the grating mount which permits thermal expansion and contraction of the substrate.

在光栅固定件中至少设置一个挠曲连接部，它允许基片热膨胀和收缩。

youdao

As the spray coating line is in the non-linear distribution, the stress of a spray coating material due to thermal expansion and contraction can not deform the filling structure.

由于喷涂线呈非直线分布，喷涂材料热胀冷缩产生的应力不会导致填充结构变形。

youdao

The probe was repeatedly turned towards and away from the sun, in the hope that thermal expansion and contraction would free the antenna, but to no avail.
