| 摘 要： | 用电子剪切散斑测试系统，对等厚圆析在沿半径方向线性温度场作用下引起的挠度问题进行了实验研究。测试结果与理论计算吻合。由此确认该测试系统可用于物体在温度场作用下的位移导数的测量，进而求得物体表面全场位移。

| Abstract: | The experimantal study of deflection induced by a radial linear temperatural field applied tothe equally thick circular plate was done by the electronic shear speckle test system. The test result is consistent with the theoretical solution. So the test system can be used in the measurement of displacement gradient of body under the temperatural field, and then all the field displacement of body's surface can be obtained. |
