As an example, we designed a new double telecentricity projection lens with NA=0.42, magnification M=-1/5, field size 15 mm×15 mm (21.2 mm diametre) and conjugate distance 602 mm.

设计了一种新的双远心投影物镜，其数值孔径NA=0.42，放大倍率M=-1/5，像场尺寸15 mm×15 mm(直径21.2 mm)，共轭距L=602 mm。

The dot pitch is the vertical distance between each pixels on a monitor .

点 距是垂直相邻两个像素之间的距离。

The method will make a break in the theory of earth-space location; achieve space-space location .

与第一种方法相比，该方法有如下优点：(1)不需要在星载SAR的视场中使用任何位置确知的参考点，因此将真正突破现存的地-空定位理论，达到空-空定位水平；(2)其定位精度将仅仅取决于星历数据的准确性、地球模型的有效性、脉冲时延所决定的目标斜距精度、以及成像中多普勒信息的估计精度。

He is too big, they all said, and the turkey cock, who had been born into the world with spurs, and fancied himself really an emperor, puffed*(3) himself out like a vessel in full sail,and flew at*(4) the duckling, and became quite red in the head with passion, so that the poor little thing did not know where to go, and was quite miserable because he was so ugly and laughed at by the whole farmyard.

大家都说。有一只雄吐绶鸡生下来脚上就有距，因此他自以为是一个皇帝。他把自己吹得像一条鼓满了风的帆船，来势汹汹地向他走来，瞪着一双大眼睛，脸上涨得通红。这只可怜的小鸭不知道站在什么地方，或者走到什么地方去好。他觉得非常悲哀，因为自己长得那么丑陋，而且成了全体鸡鸭的一个嘲笑对象。

This result shows that if the image of the Gauss map of an evolution convex surface with planar boundary covers some hemisphere, such a surface maybe be of infinitesimal nonrigidity for the isometric infinitesimal deformation of planar boundary.

这个结果表明如果带平面边界的凸旋转曲面的Gauss映照像覆盖了某个半球，这曲面对于保持平面边界的无穷小等距形变来说可能是非无穷小刚的。

Zero offset section, which is just the goal of CMP stacking in conventional processing, is an important intermediate result in seismic reflection imaging.

零炮检距剖面是地震反射成像过程中重要的中间成果，常规处理中的共中心点叠加的目的正在于此。

The paper proposes two new dimension reduction algorithms: The First is On the Expected Distortion Bound of Direct Random Projection. The second is Anchor points based Isometric Embedding under least square error criterion. On the Expected Distortion Bound of Direct Random Projection has a time complexity of O.

本文分别提出了两种新的维数约减算法：(1)基于期望扰动的直接随机映像算法On the Expected Distortion Bound of Direct Random Projection，简称DRP(2基于锚点集的最小平方误差等距嵌入算法(Anchor points based Isometric Embedding under least square error criterion，简称AIE)。

When driving over patches of highway that are battered by heavy big rigs, long-wheelbase trucks like our Crew Cab 1500 Laramie Ram test vehicle typically begin to oscillate.

当驾驶超过补丁的公路是沉重打击了大平台，长轴距像我们的卡车驾驶室乘员公羊1500拉勒米测试车辆通常会开始振荡。

By using the law of reflection,the equation of time distance curve of reflection wave under the continuous medium tilted interface,is discussed.

应用反射定律，讨论了连续介质斜界面下的反射波时距曲线方程，给出了这类模型下的成像方

Glowing like a multi-faceted jewel, the planetary nebula IC 418 lies about 2,000 light-years from Earth in the direction of the constellation Lepus.

像一颗精心雕琢的宝石，行星状星云IC 418坐落在距地球2，000光年的天兔座内。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
