head seas meaning in English
迎浪
Examples
- The strip method was applied to the motion prediction of the monohull . the time range solutions of heave and pitch were obtained in the condition of head sea to provide the primary data on panoramic simulation
本文利用切片法对0371g艇加装纵向组合减摇附体前后的运动进行预报，取得了迎浪状态下升沉和纵摇的时历解，为视景仿真提供原始数据。 - When sailing in waves , a part of ship bow will depart from water surface because of the significant heave and pitch ( mostly happened at bow in head seas , and may happened at stern in follow sea ) . when ship enter into water once again , violent impact with waves will happen , which is called slamming
当船舶在波浪中航行时，由于剧烈的垂荡和纵摇，船底的一部分会露出水面(主要是在迎浪时发生在船体前部，但在低速随浪时也可能发生在船体后部) 。 - This method applies the extended strip theory to establish the nonlinear ship motion equations in regular head seas , obtains stable time course by resolving in time domain , and then pressure vectors will be available . the pressure includes static pressure , incident waves pressure , diffraction pressure , radiation pressure , and wave impact pressure , and changed with instantaneous draft of each intersection
该方法应用扩展的切片理论建立迎浪规则波中船舶非线性运动方程，通过时域步进求解获得船舶刚体运动的稳定时历，进而给出与船体各横剖面瞬时吃水相对应的静水压力变化、入射波压力、绕射压力、辐射压力和波浪冲击压力诸分量。 - He was not only useless as an officer , and a bad influence amongst the men , but it was plain that at this rate he must soon kill himself outright ; so nobody was much surprised , nor very sorry , when one dark night , with a head sea , he disappeared entirely and was seen no more
他不仅是个在船员们中间起不良影响的无用的官长，而且很显然，若按这个情形发展下去，他一定会很快结果掉自己的。因此，在一个漆黑的夜晚，当他一头栽到海里，完全消失再也不见踪影时，没有人大惊讶或是格外难过。
