At present, there is certain localization in some formulae of transformation from geocentriccoordinates to geodetic coordinates, such as rate of calculation, stability, or precision.
目前的一些地心坐标向大地坐标的转换模型在计算速度，稳定性或精度方面存在一定的局限性。

We derived an approximate algorithm from geocentric to geodetic coordinates. The algorithm is very simple, but its accuracy can satisfied general geo-science research.
