对气垫转盘无外力矩自转现象的原因进行了探讨，理论分析和实验数据均表明：地球自转而产生的科里奥利力是气垫转盘无外力矩自转的最可能原因．这将为气垫转盘实验的改进提供重要的参考和依据．

Compared with traditional rigid - body rotating apparatus, the air - cushion turntable has many advantages, such as stable data, intuitionistic phenomena, high accuracy, etc. However, the external - moment - free rotation of its movable turnplate will slightly decrease the measurement accuracy. This paper investigates the possible causations that result in such a phenomenon. The theoretical analysis and experimental data indicate that the external - moment - free rotation is likely caused by Coriolis force resulting from earth rotation. This result will contribute to the improvement for experimental apparatus.
