摘　　要：船用气层减阻技术由于其优异的节能减阻效果而受到船舶相关行业越来越多的重视。为此,急需建立一种通用的、可接受度高的评价方法,以引导气层减阻技术的发展。论文通过梳理EEDI中关于创新能效技术的相关计算准则,理清了气层减阻技术EEDI计算中各个参数的求解方法,提出了一种基于EEDI指数的气层减阻技术评价方法,并通过国内首艘气层减阻改造船的实测数据进行了EEDI的计算。Air-layer drag reduction technology attracts more and more attention of the ship building industry because of its excellent energy saving and resistance reduction effect. A general and highly acceptable assessment method is urgently needed to guide the development of air-layer drag reduction technology. In this paper, we reviewed relevant calculation rules in the EEDI guide, clarified a method for solving parameters in the EEDI calculation and proposed an evaluation method of air-layer drag reduction based on EEDI index.Based on the trial data of a real ship, the first one modified with air-layer drag reduction technology in China,its EEDI is calculated with the proposed method.
