摘　　要：利用《航海天文历》查表的方法求取高度差法两要素,过程比较复杂。基于C++ Builder语言编程,根据求取高度差法两要素的原理,提出一种新型天文舰位线算法。实验数据表明该方法改进传统的计算机算法,提高计算效率和计算精度,具有一定的可行性。It is complex to get the two factors in altitude difference method by consulting the "nautical almanac". Based on C++ Builder, this paper introduces a new arithmetic of getting celestial ship positioning line based on the principle of getting the two factors in altitude difference method. The experiment data shows that this method improves the traditional computer arithmetic, enhances the computing efficiency and computing precision and it has certain feasibility.
