The cause of the earth tide force is its elliptic orbit movement. There is the tide caused by the earth on the moon because the earth is the focus of the moon moving orbit, but there is not the tide caused by the moon on the earth because the moon is not the focus of the moving orbit of the seawater on the earth.

地球的潮汐力是由椭圆轨道运动产生的，由于月球的轨道运动是以地球为焦点，所以在月球上可以产生受地球影响的潮汐，而不可以产生相反的潮汐，因为海水或岩浆没有以月球为焦点的轨道运动。

The WGS 84 Datum is generally accepted as the best simple mathematical model for the overall shape of the earth, and is an ellipsoid with an equatorial radius of 6378.1370 km and a polar radius of 6356.7523 km, and is centred on the earth's centre and orientated to the spin axis.

WGS 84基准﹙ WGS 84 Datum ﹚被普遍接受为地球整体形状之最简单数学模型，是一个赤道半径﹙ equatorial radius ﹚ 6378.1370公里和北极半径﹙ polar radius ﹚ 6356.7523公里之椭球﹙ ellipsoid ﹚，以地球的中心为中心点，并定位於﹙ orientated to ﹚自转轴﹙ spin axis ﹚。

Thus the data of the earth spheroidal and toroidal free oscillation can be used to explore the 3-dimensional structure(density structure ,velocity structure) or anisotropy of the earth and help to disclose the convection mode in the whole mantle or in the upper mantle.

因此地球自由振荡信息可用于揭示地球的三维不均匀结构信息或各向异性信息，并可能对区分地幔对流模式有所帮助。
