摘　　要：提出一种在船舶工程计算中具有广泛用途的用任意闭曲线裁剪任意闭曲线的裁剪方法。将这种改进的裁剪算法与环形积分法相结合编制计算模块,可将原来工程计算中繁琐的运算过程大大简化,可用来处理船舶工程中经常遇到的图形面积和形心的计算等问题。阐述其在船舶工程性能计算中的应用,并通过实例计算验证其精度。An improved and ocean engineering to calcul figure ate th the improved figure clipping method Some examples are given to illustrate clipping method is presented, which can be widely used in ship design e area and center of the figures. With the calculation module based on , these complicated operations can be simplified and realized easily. it.

关 键 词：任意闭曲线 图形裁剪 船舶性能计算
