Permission rice Lu surpasses in the sphere of action carries on the on-the-spot guidance to the player, when the necessity may go on stage the direction, but must not put on the gym suit, in order to avoid confuses.

允许米卢超出活动范围内对球员进行现场指导，必要时可上场指挥，但不得穿运动服，以免混淆。

To study the effect of gravity eccentricity on the ranges,the expression of gravity was educed using spherical harmonic function when the earth is considered as an normal ellipsoid or sphere.

为了研究地球的重力偏心对射程的影响，用球谐函数展开法推导了地球为正常椭球体和圆球体时的重力表达式，对地球的重力偏心进行了计算分析，求出了偏心值。

In sphere approximate, GPS/Gravity-BVP is Neumann problem over exterior spherical domains. Then the natural boundary reduction, suggested by Feng and Yu, is applied to deal with the three dimensional problems. By expansion in spherical harmonics, the natural integral equations of harmonic problems over exterior spherical domains are obtained. Meanwhile, a numerical method for solving geodetic BVP is developed.

With the idea of finite approximation, we study a new solution method for the satellite altimetry problem. Our result shows that if the continental part of the earth is sphere cap, then the solution of satellite altimetry problem can be transformed into a linear system of equations with variants of the coefficients of spherical harmonic series. We prove that the linear system of equations is separated about the orders of spherical harmonic series.
