摘　　要：依据波动光学关于光的干涉原理,分析和介绍了一种能产生等倾干涉现象的大顶角等腰劈干涉装置,推导并讨论了该干涉结构发生等倾干涉的条件及干涉条纹的分布规律;同时指明等腰劈的等倾干涉原理对于薄膜干涉的相似性或等价性,并讨论了其在光学领域可能的应用领域;强调了其对光学干涉的教学研究的辅助作用及内容扩充。According to the optical wave theory about optical interference, the equal inclina- tion interference in an isosceles triangular wedge with a big vertex angle has been concretely introduced and analyzed in detail the interference conditions and the distribution taws of interference rings are deduced and discussed, which are in accordance with the observed phenomena in a verification experiment. On the other hand, the application possibilities of this intercro-displacement sensor, are a/so discussed and its subsidiarity to the pedagogical practices acontents about the equal inclination interference are extended
