摘　　要：本文介绍了一种简便的测量微波延迟线所用晶棒两端面间楔角大小的方法。扼要地概述了测量的基本原理和实验装置,并对测量结果进行了误差分析。实验结果表明:这种测量方法具有结构简单,图形直观,操作方便和不受环境影响的优点。其测量精度优于1.5%。This Paper Presented a simple method for measuring wedge angle between end-faces of crystal bar used in microwave delay lipe. The rrirciplc of measw-ing. method and the experimental installation were described briefly^ and an analysis on the errors in measurement was perfoimed. The results irdicatcd that the method has the advantages of simple construction, visual picture , daisy oreration and without effects of environment, it's' measurement accuracy is<1.5%
