velocity n. 1.迅速;快速。 2.速度,速率。 3.周轉(zhuǎn)率。 at a velocity of 100 miles per hour 用每小時(shí)一百英里的速度。 dart off with the velocity of a bird 像鳥(niǎo)一樣迅速飛跑過(guò)去。 drag-free velocity無(wú)阻力飛速,真空飛速。 escape velocity(克服地球引力的)第二宇宙速度,逃逸速度。 final velocity (發(fā)射物的)終速。 initial [muzzle] velocity(發(fā)射物的)初速[腔口速度]。 uniform [variable] velocity勻[變]速。
This velocity is often called the terminal velocity . 這個(gè)速度常常稱(chēng)為收尾速度。
Excessively long fall distances are required for drops of raindrop size to attain terminal velocity . 雨滴為了得到足夠的末速度必須下降很長(zhǎng)距離。
It is concluded that the equivalent target expression and the method of calculating terminal velocity can efficiently increase the calculating precision and can be used in the battle damage simulation 結(jié)果表明:建立的等效靶公式和剩余速度求解方法顯著地提高了計(jì)算精度,可以應(yīng)用于戰(zhàn)斗損傷仿真分析中。
In this paper , firstly the macro parameter of the series connection app was comprehensively analyzed , among which the trajectory location of the bullet emission and the terminal velocity of the bullet were mainly analyzed , and the feasibility of the series connection app to cope with explosive reactive armor was demonstrated . and then the macro design about the head of the series connection app was made , among which a particular analyse about the bullet " s launching process was made , from which we concluded the relation between the thickness of the airproof loop and the velocity of the bullet detached from the carrier and the relation between the length of the bullet and the velocity of the bullet detached from the carrier and the relation between the length of the bullet and the burning rate of the powder and the relation between the length of the bullet and the maximum pressure of the emission hole and the relation between the length of the bullet and the emitting time of the bullet , and the reasonable str ucture of the head of the carrier and bullet were designed , then the intensity of the head of the carrier was checked out using of the software of ansys 本文首先對(duì)子母式穿甲彈總體參量作了全面的計(jì)算分析,其中主要分析了子彈射出的彈道位置和必要的子彈著靶速度,論證了子母式穿甲彈對(duì)付爆炸式反應(yīng)裝甲的可行性,然后對(duì)子母式穿甲彈彈頭部進(jìn)行了總體設(shè)計(jì),其中主要對(duì)子彈的發(fā)射過(guò)程進(jìn)行了詳細(xì)的分析,得出了母彈彈頭部發(fā)射孔內(nèi)閉鎖環(huán)厚度與子彈飛離母彈速度的關(guān)系、子彈長(zhǎng)度與子彈飛離母彈速度的關(guān)系、子彈長(zhǎng)度與火藥燃燒率的關(guān)系、子彈長(zhǎng)度與母彈彈頭部發(fā)射孔內(nèi)最大壓力的關(guān)系以及子彈的長(zhǎng)度與子彈發(fā)射所需時(shí)間的關(guān)系,設(shè)計(jì)出了合理的母彈彈頭部結(jié)構(gòu)和子彈的結(jié)構(gòu),并利用ansys有限元分析軟件對(duì)母彈彈頭部的強(qiáng)度進(jìn)行了校核。
英文解釋
the constant maximum velocity reached by a body falling through the atmosphere under the attraction of gravity
百科解釋
The terminal velocity of a falling object is the velocity of the object when the sum of the drag force (Fd) and buoyancy equals the downward force of gravity (FG) acting on the object. Since the net force on the object is zero, the object has zero acceleration.
