摘　　要：研究因落体旋转而造成落体位移测量的两种类型的误差:反射器折射率误差和反射器绕落体质心发生旋转造成的误差,并对两种类型的误差与反射器尺寸、落体旋转角速度的关系进行了研究阐述。Two types of errors in the measured distance of the test masses are studied, when the masses of abso- lute gravimeters has been rotate in the freefall. The one is caused by refractive indices of the retro reflector, the other is due to the retro reflector rotate by the center of mass. The relationship between both errors and the size of the re- flector and the rotation of the test mass are researched.
