摘　　要：文章说明了陀螺仪的功用,分析了陀螺仪期间核查的目的及陀螺仪期间核查周期的确定,阐述了现阶段各大检测中心进行仪器设备期间核查的方法。根据陀螺仪期间核查的时效性、便捷性,主要研究了核查标准法和设备比对法。核查标准法通过高精度陀螺仪RT3002作为标准来测量被核查的陀螺仪的加速度和横摆角速度的示值误差,确定陀螺仪是否合格。设备比对法通过同时测量3台同型号陀螺仪的加速度和横摆角速度数据,计算陀螺仪的测量不确定度,以确定陀螺仪是否合格。This paper explains the functions of gyroscopes and analyzes the purpose of periodic verification of gyroscopes,describes the determination of periodic verification of gyroscopes,and expounds the methods of periodic verification of instruments and equipment in major testing centers at this stage.According to the timeliness and convenience of gyroscope during verification,the verification standard method and equipment comparison method are mainly studied.The verification standard method uses the high-precision gyroscope RT3002 as a standard to measure the indication errors of the acceleration and yaw rate of the verified gyroscope and determine whether the gyroscope is qualified or not.By measuring the acceleration and yaw rate data of three gyroscopes of the same model at the same time,the equipment comparison'method calculates the measurement uncertainty of the gyroscopes and determines whether the gyroscopes are qualified.
