摘　　要：如子午线曲率半径M等的地球椭球要素是纬度的函数。根据函数与反函数的定义,论证了反解的存在并导出了初等函数的反解公式,给出了CASIOfx-4800P计算器反解超越方程的计算程序。所有反解程序的正确性已为实例计算证明。The elements of earth-ellipsoid such as radius M of curvature in meridian are the function of latitude. According to the definition of function and anti-function, the authors demonstrate the existence of anti-solution and deduce the anti-solution formula of elementary function. They give the anti-solution computing program of transcendental equation for CASIO fx-4800p calculator. The correctness of all anti-solution program have been proofed by example computation。
