1·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。

2·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。

3·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。

4·The effects of thermal circling on the curve of heat expansion and cold contraction are investigated.

研究了热循环对铝基复合材料热膨胀和冷却收缩曲线的影响。

5·It can be effectively separate the noise and vibration as its have some space at the end of the tube, the pipeline is not affected when thermal expansion or contraction.

因管末端有间隙可有效地隔断噪音及振动地传播，热胀冷缩时管路亦不受影响；
