| 摘 要： | 本文给出了从光弹性数据中决定平面应力分布的最小二乘求解方法。与传统的剪应力差法比较,可同时获得应力模型的全部解,不出现积累误差,从而获得较大的精度;不需单独测定材料条纹值,简化了实验步骤。

| Abstract: | The methol of least squares is used to determine planestress distributions from Phgtoelastic data. Compared with the traditional shear-difference method, all solutions can be obtained simultaneously. This method is more accurate because the accumulative error is not present and the process is simpler as it is not necessary to determine the material fringe value separately. |
