摘要：通过引入一组“帐篷”函数来近似船体函数，将波浪阻力的米歇尔积分简化为船舶偏移量的标准二次形式。具有类型 0 小于或等于 H(x,z) 小于或等于 B 的线性不等式约束； C 小于或等于 Hx(x,z) 小于或等于 D，（H(x,z) 为船体函数；B、C、D 为常数），应用二次规划技术可以找到最小波浪阻力的各种最优船型。根据船模拖曳水池试验的大量计算结果，选择了三种最佳形式。 （作者）
Abstract : By introducing a set of 'tent' functions to approximate the ship hull function, the Michell integral for wave resistance is reduced to a standard quadratic form in terms of ship offsets. With linear-inequality constraints of the type 0 less than or equal to H(x,z) less than or equal to B; C less than or equal to Hx(x,z) less than or equal to D, (H(x,z) is hull function; B, C, D are constants), it is possible to find various optimal ship forms of minimum wave resistance by applying quadratic programming techniques to the problem. Three optimal forms have been chosen among a number of computed results for tests in the ship-model towing tank. (Author)
