凹的

After the first spacer is in place and dry, place the concave side of the objective lens flush against it, and put the other spacer snugly against the lens to hold it in place (again using the drill - glue method).

在第一次间隔到位，干燥，放置在物镜反对冲凹侧，并提出对镜头的其他间隔紧贴举行的地方。

The second lens group includes a 2nd-group 1st positive lens, a 2nd-group 1st compound lens formed by joining a 2nd-group 2nd positive lens having a convex surface on the image plane side and a 2nd-group 1st negative lens having a concave surface on the screen side, and a 2nd-group 3rd positive lens arranged in that order from the screen side toward the image plane side.

第二透镜组包括一个第2组第一正透镜，一个由在像平面侧具有凸面的第2组第二正透镜和一个在屏幕侧具有凹面的第2组第一负透镜结合的第2组第一组合透镜，和一个第2组第三正透镜，它们以从屏幕侧到像平面侧的顺序布置。

By a concave spherical mirror and the mirror curvature center is located in a very close parallel plate of non-spherical corrections boards.

由一个凹球面反射镜和位于反射镜曲率中心的一块很接近平行平板的非球面改正板组成。

The beam sizes reflected from the concave mirror and the plane mirror are 48 mm and 5.1 mm,respectively.

得到由凹面镜和平面镜反射回来的光斑直径分别为4.8 mm和5.1 mm，平凹腔的角度对准精度达到了3.18′。

Tess of the method used in OpenGL draw concave polygon, called a very simple and saved a lot of the complexity of the work of the test.

详细说明：用Tess的方法实现OpenGL中画凹多边形，调用非常简单，而且省去了大量的复杂工作，测试通过。

The implementation process of the algorithm is as follows: First, the scanning lines of each contour are generated, while the contour's shape can be divided into convex polygon and concave polygon, and the generating process of the scanning lines of each contour needs special treatments .

首先依次生成每个轮廓的轮廓扫描线，由于轮廓形状可能为凸多边形也可能为凹多边形，所以在生成各轮廓的扫描线时要增加一些特殊处理操作。

My account is concave, and so deep I born.

我的就是凹进去的，并且很深我天生就这样。

In general, an industrial component may have both convex and concave portions as part of its boundary.

一般来说，工业组件可能有个凸，凹这两部分的一部分，它的边界。

One is concave whereas the other is convex and faces the longitudinal plane of symmetry X.

一个是凹入的，而另一个是凸起的，并面向纵向对称面X。

Concavely took shape regarding the side uses the lifting gear to pull out the core organization and the simple reasonable cooling system.

对于侧凹成型采用了提升装置的抽芯机构及简单合理的冷却系统。

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。
