新细长船理论是近几十年来发展起来的，在波浪阻力计算过程中得到了广泛应用。本文以三体船为例，基于修正Noblessis细长船理论，通过展开指数函数分离变量，建立了三体船的波浪阻力kochin公式。用这些公式可以快速计算波浪阻力。数值计算结果与模型试验结果吻合较好。从而证明了细长船波浪阻力理论的可行性，可以应用于高速多体船的波浪阻力计算。
New slender-ship theory is widely used in the calculation process of wave resistance, which has been developed in the past decades. In this paper, taken trimaran as example, based on modified Noblessis slender ship theory, where the variables are separated by expanding exponential function, the trimaran's wave resistance kochin formulae is established. The wave resistance can be calculated rapidly with these formulae. The numerical results coincide well with that of the model test. So the feasibility of the new slender ship wave resistance theory is proved and can be applied to calculate the high-speed multi-hull's wave resistance.
