摘　　要：参照待定系数法,利用计算机代数系统Mathematica对高斯投影正反算作了进一步的推导,得到了比以往精度更高的数学表达式.在此基础上进行精度分析,提出了比较完善的高斯正反算的推导思路,为满足实际工作中对公式精度的要求提供了一个更加完善的解决方法.Referring to the method of undetermined coefficients,the paper makes a further derive of solution of Gauss Projection with the help of computer algebra system Mathematica and these formulas are more concise than the previous ones.On the basis of the formulas,the paper carries out accuracy analysis,and proposes a more advantegeous approach to derive solution of Gauss Projection to meet high accuracy requirements in the work.
