摘　　要：本文对大方形系数(C_B=O.90)船型的经济性首次进行了论证与探讨。文中简述了大方形系数船型经济论证程序的设计思想,给出了数学模型,并作了大方形系数船型与G型2万吨级散货船、秦申线3.5万吨级浅吃水运煤船的经济性对比及敏感性分析。初步论证表明,大方形系数船型具有良好的经济性,是一种值得进一步开发的经济船型。An economy analysis of a ship form with its block coefficient equal to 0.9 is presented. The design ideas of the economy analysis program for a ship with high block coefficient and some mathematical models such as that for estimating the light weight of a ship and the shipbuilding cost, for the type depth as well as for predicting the ship speed are given. With the main dimensions and main engine power of the ship unchanged, economy comparisons between a ship with high block coefficient and a 20 000 dwt bulk carrier, a 35000 dwt shallow-draft coal carrier have been carried out and sensitivity analysis made. Calculation results show that the economy of ships with high block coefficient is fairly good.
