中文摘要：
针对传统船型优化存在耗费时间长、优化效率低的缺点,文章提出一种基于偏相关性的船型优化设计方法。该方法利用偏相关性分析,对船体外形与兴波阻力的相关规律和经验进行总结,并将这种设计经验引入到优化设计中,可以缩小相关设计变量的取值范围,显著提高优化效率。利用该方法对哈特曼函数（Hartman function）以及KCS集装箱船的兴波阻力进行优化计算,通过对比分析,证明了该方法的可行性。
英文摘要：
Aiming at the problem of time-wasting of the traditional optimization design method, the paper proposes a new hull form optimization method based on the analysis of partial correlation. By using the method of the analysis of partial correlation, the correction between hull form geometric parameters and wave-making resistance is summarized. The correction is applied to the hull form optimization, which can reduce the scope of related design variables and improve the efficiency of optimization. Using the method to do optimizing calculation of Hartman function and the wave-making resistance of container ship KCS. The comparing analysis verifies the feasibility of the method.
