This paper studied the relationship between impulsive moment of radial tidal current and Alai phenomena, and concluded that: M acting on the earth's axis inspires Chandler wobble; the change of M depends on the interaction of the water, tidal force and the effects of the earth's rotation; under certain conditions, M changes dramatically during eclipse, which makes the amplitude of Chandler wobble change in the form of pulse.

本文研究了径向潮流冲量矩M与阿莱现象的关系，得出的结论是：M作用于地轴激发了Chandler摆动；M的变化取决于海水、引潮力和地球自转效应的相互作用；日食或月食期间，在一定的条件下，M变化的非常剧烈，引起Chandler摆动振幅脉冲式的变化，进而引起地球纬度的变化，最终导致地球表面重力加速度的变化；这种变化可以通过傅科摆摆动平面角速度的变化或重力计的示数变化反映出来。
