| 摘要: |
| 由于领海基线一般由折线组成且地球表面为球面，基于领海基线外推领海、毗连区和专属经济区的实际计算存在困难。文章基于交圆法设计最短距离法和椭圆法2种算法并对其优劣性进行比较，研究表明：外推12 n mile领海和24 n mile毗连区的界线基本与外推的领海基线平行，外推200 n mile专属经济区的界线形状变化较大；最短距离法精度高但计算量较大，椭圆法所需计算时间短但精度较低且没有消除误差。 |

| Abstract: |
| Since the baselines of the territorial sea are generally composed of lines and the surface of the earth is spherical,the actual calculation based on the baseline of territorial sea for the extrapolation of the territorial sea,the contiguous zone and the exclusive economic zone is difficult.Based on the intersection method,this paper designed and compared two algorithms: the shortest distance method and the ellipse method.Research showed that the boundary of the extrapolated 12 n mile territorial sea and the 24 n mile contiguous zone is basically parallel to the extrapolated territorial sea base line.The boundary of 200 n mile extrapolation exclusive economic zone changes a lot.The shortest distance method has high precision but a large amount of calculation.The ellipse method needs shorter calculation time but lower precision and does not eliminate the error. |
