Based on this Sailing Program and MATLAB ,we compared rhumb line with great circle line , and discussed the relationship between voyage and other parameters .Finally , we drew the conclusion.

最后借助于航线设计程序和MATLAB，我们对两种航线进行了比较，讨论了两种航线航程之差和航线的其他参数之间关系，并得出了结论。

Firstly, the thesis introduced some methods on spherical problems and restudied the analytical methods for calculating rhumb line, great circle line and composite navigation line.

该论文总结了一些和球面问题有关的实用公式，并对等角航线、大圆航线、混合航线设计的算法进行了深入的研究。

Then, a Visual C++ program named Sailing Program is written to do following works: to calculate the parameters of rhumb line and great circle line ; to design the great circle line when it is necessary ; to design the composite line when it is necessary; to print tracks of rhumb line and great circle line on Mercator chart.

我们用Visual C++设计的航线设计程序，可以计算出两点之间大圆航线和等角航线的相关参数；如果有必要进行大圆航行的话，程序将计算出大圆航线的航路点；如果需要混合航行的话，程序将进行混合航线设计。

The great circle sailing is composed of segments of rhumb line sailing in theory and practice. The waypoints along the great circle track are determined under the given initial conditions by the navigators.

大圈航法在实务上系为分段的恒向线航法，而各分段之转向点位置的决定则有赖於航海人员所给定的初始条件。

Ship always select rhumb line when the voyage is short while great circle line is the shortest route , so it is always used during the oceangoing voyage for the purpose of voiding the terrible environments in the high latitude sections , sometimes we have to turn to composite navigation line .

等角航线是最简单，短程航行中最常用的航行方式；而大圆航线是跨洋长距离航行时经常采用的，地理航程最短的航线；在大圆航行的过程中，有时为了避开高纬度地区的恶劣环境，我们还要选择混合航线。
