摘　　要：实际生产过程中加速度计标度因数重复测试结果总有10-5m A/g量级误差,为查找原因,对加速度计进行重力场静态翻滚四点法试验,利用加速度计测试系统的原理,对标度因数进行测试和计算,通过研究标度因数的测量不确定度,找到了影响加速度计标度因数的测量误差来源,证明了重复性测试误差在合理范围内。In the production process,the repeatability test result have a 10^-5 m A/g error of the accelerometer scale factor,accelerometer＇s static rolling four-point test is performed. Based on accelerometer test system testing principle,the accelerometer scale factor is tested and calculated,and the measurement uncertainty of scale factor is studied. The measurement error source that affects the accelerometer scale factor is found,and proved that the repeatability error is within a reasponable range.
