会聚

Has two converging lens system; the objective and the ''.

有两个会聚镜头系统；物镜和目镜。

A beam throgh convex lens will be converged, so the lens is also called a converging or positive lens.

凸透镜具有会聚光线的作用，所以也叫"会聚透镜"或"正透镜"。

The invention relates to an objective lens for converging light emitted by a light source to irradiate an optical recording medium with the convergent light, an actuator having the same, an optical head for recording information on the optical recording medium and reproducing information recorded on the same, and an information recording/reproducing apparatus utilizing the same.

本发明涉及将从光源射出的光会聚并将聚焦光照射到光学记录介质上的物镜和配备有该物镜的致动器、以及将信息记录在光学记录介质上或对所记录的信息进行再生的光学头和使用该光学头的光学记录再生装置。

Therefore, the crepuscular rays from a setting sun will appear to re-converge on the other side of the sky. At the anti-solar point 180 degrees around from the Sun, they are referred to as anticrepuscular rays.

也因此，来自落日或旭日的云隙光，视觉会在反向的天空重新会聚在一起，形成了一个和太阳相隔180度的反日点，这种光线特别被称为是反云隙光。

This period is a normal cross-eye baby, baby do not be condensing two months, once to see what he will be more concentrated on the eyes of.

这时期宝宝斗鸡眼是正常的，两个月宝宝不太会聚光，他一旦看什么比较集中就会把眼睛对上的。

Naturally, it is also a place where the best stone cutters gather together.

当然，这也是一个地方，最好的石材切割机会聚一堂。

Referring to the function of cylindrical lens and the principles of holographic optical elements, we make this holographic element, which can achieve the optical function of cylindrical lens, and have the advantage of large-scale, short focal length and well-distributed light energy, in order to meet the requirements of laser direct writing synthetic holograms.

实验结合激光直写合成全息拍摄时所需柱面透镜的功能，参考全息光学元件的制作原理来制作图像柱面压缩全息光学元件，实现柱面透镜的光学功能，并使元件具有大面积、短焦距、会聚光均匀分布的特点，满足激光直写合成全息拍摄对图像的需求。

In a this tube pair of deflection plate, besides demonstration electron under electric field role deflection movement, but also played causes the beam convergence the function, if causes two deflection plates the electric potentials to be lower than the acceleration extremely electric potential approximately 30 volts, then the focusing condition is best.

该管内的一对偏转板，除了演示电子在电场作用下的偏转运动外，还起了使电子束会聚的作用，如使两偏转板的电位低于加速极电势约30伏，则聚焦状态最佳。

Deity 1:Don't tease her. We seldom have a chance to be here.

神仙 一：你就别再消遣她了，我们可是很少有机会聚在一起的。

The new NKF presented Dinner and dance at Orchid hotel this year.

平时大家都是穿着工作服在透析中心奔波忙碌，难得有机会聚在一起展示真正的自我，所以 party 的主题是打扮成自己喜欢的电影人物，展示自我。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
