摘要

文章对微波布拉格衍射实验中入射角较大时的异常峰值，进行了理论分析，计算出了异常峰值出现的临界入射角和理论角度值。在求解临界入射角时，改进了已有方法，考虑了接收喇叭张角的影响，使得临界入射角的计算值更加准确，成功解释了实验中出现的所有异常峰值，验证了对其成因的分析。

Abstract:

In order to analyze the cause of abnormal peaks in Microwave Bragg Diffraction Experiment withlarge incident angle,theoretical analysis is carried out,the threshold incident angle and theoretical angles otabnormal peaks are calculated.When solving the threshold incident angle,the existing method is improved,theinfluence of the horn angle of the receiving horn is considered, which makes the calculated value of thethreshold incident angle more accurate , successfully explains all the abnormal peaks in the experiment andverifies the analysis of the cause of the abnormal peaks.

Key words: Bragg diffraction abnormal peaks threshold incident angle horn angle
