中文摘要：

给出了求解代数曲面上两点之间测地线的一种算法.在算法中,把决定代数曲面测地线的微分方程组离散为一个非线性方程组,然后采用迭代数值方法求解.为此,给出了一种基于细分的初值生成方法.最后给出了一些数值算例用来验证算法的有效性.

英文摘要：

An algorithm for computing the geodesic line between the two points of an algebraic surface was presented. The system of differential equations for a geodesic line on an algebraic surface was discredited into a nonlinear system. Then it was solved numerically based on iterative methods. In order to get a better convergence, a method based on subdivision was designed to specify initial values for the iterations. Examples show the efficiency of our method.
