平面坐标（自然坐标）到大地坐标的高斯反算，VISUAL LISP开发环境-Gauss inverse of the plane coordinates (natural coordinates) to geodetic coordinates

UTM投影采用6度分带,从东经180度(或西经180度)开始,自西向东算起,UTM反算(UTM projection uses 6 degrees belt, from 180 degrees east longitude (or west longitude 180 degrees) start, from west to East count, UTM counter)
