第二点

Use object snaps to accurately place the mirror plane, especially if you want to join a surface and its mirrored copy.

在镜像平面的结束点的提示下，选择第二个点来定义一个镜像平面。

The curve begins at the point where the ellipse intersects the first radial and extends counterclockwise to the point where the ellipse intersects the second radial. A radial is a line segment drawn from the center of the ellipse to a specified endpoint on the ellipse.

曲线由椭圆与第一个径向线相交的点开始逆时针延伸到椭圆与第二个径向线相交的点（径向线是指从椭圆的中心向椭圆上给定的终点之间的一段连线）。

It is possible that shunt currents flowing through a previously made spot weld will take welding current away from the second second spot weld to be made.

有可能通过前一个完成焊点的分路电流将使电流远离将要操作的第二个焊点。

At the first step,the key frame selecting from the sequence,the robust features extracting and corresponding of multi-images of sequence are accomplished.At the second step,two views which are far away enough and sharing lots of correspondences are selected.

首先提出了基于视差分析的序列图像关键帧选择方法，对关键帧图像特征点进行鲁棒性的提取与匹配；第二步用加权的RANSAC算法估计基础矩阵，同时获取准确匹配的内点集。

Furthermore, a optimization model is established to get a necessary and suff icient condition. The arithemetic of the second questino fits the third question as well.

对于第二题，本文发现坐标变换时各点之间的欧氏距离不变，利用各点的距离关系，给出一系列的判定条件，最后用优化算法判定。

Three kinds of embryos' chromosome, including goat fertilization embryo, goat-goat cloned embryo and goat-rabbit cloned embryo were analyzed, The results showed that all of them have 60 chromosomes with same character, all were telocentric chromosome, besides the X-chromosome is the second larger telocentric chromosome.

经对超排获得的山羊受精胚、山羊同种克隆胚和羊-兔异种克隆胚的囊胚期胚胎染色体分析表明，三种来源的胚胎其染色体数目均为60条，且所有常染色体均为端部着丝点染色体，X染色体为第二大的端部着丝点染色体，说明山羊同种克隆胚和山羊-兔异种克隆胚均为山羊的核型，是供体细胞核在不同胞质中的重新编程的结果。4。

In the first phase, the thesis divides a whole distribution region into many customer subsets by radius-circle partitioning method, and solves the inventory supplement problem. In the second phase, the thesis introduces improved VRP algorithm to optimize transportation route.

第一阶段以同时优化运输和库存成本为目标，在制定个体最优的补货方案基础上，设计基于遗传算法的径－环分割法对众多客户点进行分组，减小问题规模，同时进一步明确基于整体最优的客户点配送量；第二阶段运用改进VRP蚁群算法对运输路线优化。

This is because the second control point is directly behind the one you can see in the front viewport.

这是因为在前视口中，第二个控制点是你能直接看到的那个点的后面的那一个点。

Originally eat 150ML / day five times, from 3 months after I go to work, feeding on a problem, to the present or each 150ML, 4 months after the beginning of Garmisch powder, half spoon of rice cereal to tune, out to 3 / 4, also increases over egg yolk, as not interested in hindsight, she always seemed reluctant to eat, they cut into the 4 th day of milk, the volume of the same, plus 1 / 3 spoon of rice flour in milk, the still do not have to闹着eating, tongue is not white, the other what is good and can play love to laugh, to sleep or every two hours during the day we should sleep 23:30 after eating milk can sleep the next morning, 8:30, still do not seem hungry.

原先能吃150ML/每日五次，从3个月我上班后，吃奶就成问题，到现在还是每次150ML，4个月时开始加米粉，半调羹米粉调的米糊能，吐出去3/4，也加过蛋黄，一样没兴趣，后来看她吃饭总是显得不情愿，就减成一日4次奶，量不变，加1/3调羹米粉在奶里，还是不闹着要吃，舌苔不白，其他什么都很好，能玩爱笑，睡觉也好，白天隔2小时就要睡一觉，晚上11点30分吃完奶能睡到第二天早上8点30分，还是不显得饿。

Firstly, the object's position and orientation are determined by a vision system, the orientation of an object is the angle between the X-axis of the coordinate system and the axis of the least moment of inertia of the object in this system, and the position value is the vector between the coordinate zero point and the object's centre of gravity.

第一步利用视觉转动惯量法对任意放置在CMM工作台上的工件状态进行定位和定向；第二步利用测量离散点和模型投影点之间的关系，求取工件坐标系和设计坐标系之间准确的转换关系。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
