摘　　要：四频差动激光陀螺的磁效应是制约其精度提高的重要误差源之一。从四频陀螺工作原理出发,分析其物理机制,提出一种减小磁效应的新方法。基于光强差稳频思想,通过改变稳频判定标准,选择最佳稳频点;同时采取针对性措施,确保陀螺相关参量特别是总光强的稳定性。实验结果验证了此方法的有效性,对研究者有一定参考意义。The magnetic effect is one of the important error sources that limits the precision of four frequency differentia/laser gyro. Physical mechanism is analyzed from the operational principle of differential laser gyro, then a novel method of decreasing the magnetic effect is presented. Based on the concept of light intensity difference frequency stabilization, the most suitable frequency stabilization point can be chosen by changing the judging standard of frequency stabilization. At the same time, some pertinent measures are adopted to ensure the stability of the gyro parameters especially the total light intensity. The validity of this method is verified by the experiment results
