倒转的

Know to all, The refract wave exist an precondition, that is the bottom medium velocity is bigger than upper, then medium interface produce the refractive wave, if the medium exist the speed turn in reverse, and low speed in false bottom, the medium interface can not calculate.

众所周知，折射波存在的前提是下层介质的速度一定要大于上层介质的速度，这样才能在界面形成折射波，如果存在低速夹层和速度倒转，则利用折射波来求取表层结构难以进行。

Past reversals have taken place over a short period of time geologically speaking, 10,000 years or so.

过去的倒转在地质学上的说法是发生在一个短的时期，大约1万年。

With the hour-glass the unit of time is the interval the sand takes to flow from the upper to the lower glass. The same physical process can be repeated by inverting the glass.

例如使用沙漏的时间单位便是沙由上面的玻璃瓶流到下面的玻璃瓶的时间间隔，把玻璃瓶倒转过来就可以重复这个物理过程。

In this book a city is constantly and painfully pushed forward on rails because the world-picture of its inhabitants is of a hyperboloid where time and space are progressively distorted both north and south of an always moving optimum line.

普莱斯特以自己的作品对奥尔迪斯的《不停》致敬——是《倒转世界》（1974），在这本书里，所在是个时空逐步被扭曲的双曲面世界，一座城市被迫不停地前行。

When converting a CAM motion (X,Y,Z tool tip part position and I,J,K tool axis vector) to the NC tape (e.g.: X,Y,Z machine linear axes position and A,B rotary heads) the application of inverse kinematics makes the output curve completely different from one generated by the CAM system.

当将一个凸轮运动（X、 Y，Z 工具顶端部份位置和我、 J，K 工具轴矢量）转换成收据控制以带子绑起（举例来说： X 、 Y ， Z 机器线性轴位置和 A，B 旋转的头）倒转运动学的申请的时候让输出曲线完全不同一被凸轮系统产生。

Another drawback of these techniques is that they need numerical pre-processing like inverse fourier transformation or convolution to compute the field induced time-domain sources.

这些技术的另外一个不利点是他们数字的预先处理相似的倒转 fourier 变形或回旋计算领域感应时间-领域来源。

The internal door latches look more realistic all the time and the visors flip up on little silver mounting points.

内部的门闩始终变得更现实，而且复面倒转在小的银展开点上上面。

In normal state,δ13C in biogenic alkane gas increases, while its component content decreases, with increase of the carbon numbers. In Section-1 gas pool of Leikoupo formation of Middle Triassic in Moxi gas field of central Sichuan, both of the component content and δ13C series appear reversals.

正常状态下，有机烷烃气的碳同位素值(δ13C)依碳数递增而递增，其组分含量依碳数递增而递减，而川中磨溪气田中三叠统雷口坡组一段气藏，有机烷烃气的组分含量和碳同位素系列却出现了倒转。

The used-car dealer was convicted of rolling back odometers and other unconscionable business practices.

这位买卖旧车的商人因倒转里程计以及其他昧着良性的生意伎俩被判有罪。

One day it took to make my small world turn over, full of amazing grace and complicated tastes.

只一天我的小小世界就被倒转，充满了奇异的恩典和多彩的滋味。

Do you know, i need you to come back

你知道吗，我需要你回来
