摘　　要：从内河引航的实践出发，通过对船舶作曲线运动的特征及规律的分析研究，拟建立一套合理的坐标体系，根据船舶曲线运动特征，确定求取其相关要素的方法．以弯曲河段为例，推导出船舶作曲线运动时求取重心坐标的数学模型，供内河引航技术理论的量化研究和运用计算机拟定内河引航中的计划航线作参考．On the basis of the practice of pilot on inland rivers, through analysing the features and rules which ships make curved motion, the paper establishes a set of reasonable system of coordinates. According to ships curvilinear motion feature, it determines a method of solving for its relative elements. Taking the curved areas of rivers as an example, it derives a mathematical model of solving for the centre of gravity coordinates when ships make curved motion. And this model can be taken as a reference for quantitative study of inland river pilot technicality theory and working out planning routes of pilot on inland rivers by using computers.
