摘　　要：辐射捕获是影响激光陀螺性能的重要色散效应。针对以往研究方法的缺陷,提出新的修正方案。基于对辐射捕获物理过程的严格考察,提出了二频陀螺的修正公式,解决了Aronowitz理论公式的缺陷;基于对四模激光器模耦合作用的严格考察,提出了四频陀螺的修正公式,符合物理本质。这对激光陀螺的理论研究有参考价值。The radiation trapping is an important dispersion effect which can greatly affect the performance of laser gyro. Focusing on the defects of previous methods, new correction methods are presented. Based on the strict analysis of the radiation trapping physical process, the correction formula of two frequency laser gyro is presented, which can solve the defects in the Aronowitz＇s method. Based on the strict analysis of mode coupling effects in four mode lasers, the correction formula of four frequency laser gyro is presented, which is in accordance with the physics essence well. It is helpful to the theoretical research on laser gyro.
