1.Each hose can be expanded and contracted independently. Doing so in sequence along the length of the torus generates forward motion.
每一个软管都可以独立伸缩，软管们在圆环体结构上顺次伸缩，产生向前移动的动力。
2.This takes him out of horizontal balance, and creates a slight "hitch" or break in his forward motion, as you can see in the video.
这个动作使得他的身体打破了水平状态，导致身体在向前滑行时有停顿，你可以在视频内看到这一点。
3.The fish pushes water aside by the forward motion of its head and with a curve of its body and its flexible tall.
鱼通过头向前运动以及身体曲线和灵活的尾巴而把水推向两侧。
4.Then he put his summons book back in his hip pocket and with the forward motion of his hand drew the . 38 Special.
然后他把传票薄放进了自己裤子的臀部口袋，随手抽出一支特制手枪。
5.A hinged or pivoted device adapted to fit into a notch of a ratchet wheel to impart forward motion or prevent backward motion.
掣爪，棘爪一种枢轴或转轴器械，能与齿轮缺口或齿间吻合来前进或防止后移
6.a back and forward motion of a sliding lever ejects the empty shell case and cocks the firearm and loads a new round.
来回运动的滑行杠杆喷射出空壳翘起火器进行新的一轮。
7.It relies on the craft's forward motion to draw in air and on a specially shaped intake passage to compress the air for combustion.
它靠飞行器的向前运动吸进空气，用特殊形状的进气信道把空气压缩，供燃烧之用。
8.The angle helps the craft's wings to provide a lifting force and translate some of the vertical motion into forward motion.
倾角可以帮助航行器提供一个向上的升力并将一些垂直运动转换为前进运动。
9.So you should also be able to get the rotational kinetic energy out and convert that again into forward motion.
这样你也能，得到旋转动能，再次转化它，变成别的能量。
10.Thus it came about that the forward motion of progressivism came to a halt in the early uncertain months of 1939.
这样，在一九三九年不稳定的头几个月，进步运动的前进步伐停止了。
