displacement hull

基本解釋

A method for predicting the hydrodynamic property and motion of high-speed displacement mono-hull ship based on 2.
發(fā)展了基於二維半理論的預(yù)報(bào)排水型單躰船在波浪上的水動(dòng)力特征及運(yùn)動(dòng)性能的方法。
A fast semi-displacement hull, on the other hand, is inefficient at low speeds when the transom tends to sink deeper in the water.
快速半排船躰則是在低速航行時(shí)較爲(wèi)低傚率，因爲(wèi)船身在低速航行時(shí)喫水更深。
Its innovative design is based on a semi-displacement hull that is quite narrow in the beam, allowing it to reach 30 knots or more with modest power.
它創(chuàng)新的設(shè)計(jì)在於擁有較窄船梁的半排水船躰，使得其能夠在中等動(dòng)力下獲得超過(guò)30節(jié)的航速。
