然后，分别进行了热循环实验与射线辐照实验。

Then thermal cycling stability and radiation exposure experiments are performed to simulate the space environment.

使用该装置可以对接触网短路热循环实验各个测温点进行循环测量。

Using this device can control the test point of contact line in shortcircuit and heat cycle experiment of catenary, as a result, the temperature of contact line can be measured.

实验表明，焊缝几何尺寸和焊接热循环的计算值和实测值吻合良好，这一方法可用于焊缝几何尺寸的预测和控制。

The experiments show that the predicted weld dimensions are in agreement with the measured ones, and the geometry sizes of the weld can be predicted and controlled by this way.
