中文摘要：
研究了一种利用Jacobi多项式计算倾角函数的方法，该方法表达式非常简单，不存在k和l是否同奇偶和计算非整数阶乘的问题，也不存在k〈0和k≥0的转换问题，递推公式可使用标准的Jacobi多项式的递推公式．而且，计算精度和适应阶数可与Gooding方法相当，计算时间比Gooding方法省9％．
英文摘要：
In this paper, a method to calculate the inclination function with Jacobi polynomials is introduced. Its expressions are very simple. With this method, it is unnecessary to distinguish whether k and l have the same parity, to calculate the non-integral factorial, and to convert from k 〈 0 to k ≥ 0. We can use the standard Jacobi polynomial program to compute inclination function. Its accuracy is the same as Gooding＇s method, and the computing time is 9% less than Gooding＇s.
