roll period中文什么意思
例句與用法
- The experiment is carried out on a rolling platform whose rolling period can be adjusted continuously
在最大搖擺角度為30 ，搖擺周期連續(xù)可調(diào)的搖擺臺(tái)上進(jìn)行了實(shí)驗(yàn)研究。 - The available maximum rolling angle of the platform is 30 and in the experiment the maximum rolling angle 10 , 15 , 20 was chosen . the rolling period of the platform is selected with 5 second , 7 . 5 second and 10 second
實(shí)驗(yàn)中選定最大搖擺角度為10 、 15和20 ，搖擺周期為5秒、 7 . 5秒以及10秒，以及一些分離周期值。 - But the influence trend of the maximum rolling angle and the rolling period was not so simple , it was because the influence of which embodied in the phase relationship of mass flow and the pressure drop across the tube . the d - partition method was developed to separate the test tube into four regions and the drift flow model was imported into the two phase region , based on which the solution of the response of the pressure drop of tested tube to the inlet mass flow perturbation can be obtained
在不搖擺和搖擺工況下，采用d分區(qū)法對(duì)實(shí)驗(yàn)段進(jìn)行分區(qū)，在兩相區(qū)采用漂移流模型對(duì)實(shí)驗(yàn)段的壓降對(duì)入口流速擾動(dòng)的響應(yīng)進(jìn)行了求解，給出了各區(qū)壓降響應(yīng)的表達(dá)式，進(jìn)而得到了在不搖擺和搖擺工況下，壓降與入口流速擾動(dòng)之間的傳遞函數(shù)。 - The anti - rolling tanks have three types including passive anti - rolling , controlled passively anti - rolling tank and active anti - rolling tank . the controlled passively anti - rolling tank has high performance , and it can adjust the water oscillation period through the valves in the upper of side tank in order to adapt the roll period . thus the controlled passively anti - rolling has favorable effect in the any states
其中，可控被動(dòng)式減搖水艙是一種高效能的減搖水艙，它可以通過(guò)自動(dòng)控制系統(tǒng)調(diào)節(jié)邊艙頂部的氣閥開(kāi)關(guān)來(lái)調(diào)節(jié)水艙內(nèi)水流振蕩周期，以適應(yīng)經(jīng)常變化的橫搖周期，保證在任何海浪作用下水艙都具有良好的減搖效果。
