摘要
在光弹性试验中，由于各种不利因素的影响，往往不能精确测得等差线级数。本文介绍了用应力梯度曲线的方法，较精确地得到所测条纹级数，从而使试验和计算结果更准确。
In photoelasticity experiment,it is usually difficult to measure the series of equidifferent line precisely due to various factors.The paper introduces a method of stress gradient curve,with which we can get the figure measured more precisely and make the results of the rexperiment and calculations more accurate.
