一般晶体中，都不同程度的存在着残余应力，通常称为静态内应力。若光学介质中存在这些内应力会对实验造成一定影响，因此对晶体进行应力测量具有重要意义。本文用退偏度来描述静态内应力产生的双折射效应对偏振光束的影响，即用消光比参数来衡量静态内应力。

Crystal, are usually exist different degrees of residual stress, often referred to as static internal stress. If the optical medium ex-ists in the internal stress will cause certain influence to the experiment, so the crystal stress measurement is of great significance. In this pa-per, degree of depolarization is used to describe the static stress of the birefringence effect of polarized beams, ie.use the extinction ratio pa-rameter to measure the static stress.
