光线

The eyes need several minutes to adjust to the dimness.

眼睛需要几分钟时间适应昏暗的光线。

"Such language," says a voice in the dimness, and Malfoy freezes.

"说什么呢，"暗淡的光线中有声音响起，Malfoy僵住了。

I'm not saying exactly what is an adequate Barry Factor. My wife grows her Pinguicula and Nepenthes with a Barry Factor of around 70% and does just fine. But I grow Sarracenia, aquatic Utricularia, and Dionaea, and they need a lot of light.

我不会精确地定义合适的Barry系数，我老婆的捕虫堇和猪笼草在70%的环境下长得不错，但是我的瓶子草、水生狸藻、补蝇草则需要大量光线。

Cat's Eye Diopside is mainly mined in India .

猫眼状闪光或猫眼效果是光线折射的结果，在宝石表面出现单一的一条光带。

Objective: To observe the pupil diameter changes of different diopter under different rays.

目的： 观察不同的屈光度在不同光线下瞳孔直径的变化。

One prism diopter represents a 1 cm deviation at 1 m.

一个棱镜度表示光线通过棱镜后在1m 处有1cm 的偏移。

The bright light showed up the dirtiness of the room.

明亮的光线使房间的肮脏显现了出来。

The national education does'nt disburden parents' responsibilities for their children.

房子周围的树太多常会影响房子的光线和空气。3。国家教育并未解除家长对其子女的责任。

The spectra of stars and galaxies almost always show a series of discrete lines that form when certain atoms or molecules emit or absorb light.

星体和星系的光谱几乎总是表现出一束不连续的线，这些线形成于某些原子或分子发射或吸收的光线。

Based on the traditional geometric optics principles and the method of ray tracking, this paper reports the calculation of the aberration of the mode index lens when the collimated beam incidents upon it inclinely with an angle, and the divergency of the output beam from the MIL when it works as a collimator for the end-butt coupling between the semiconductor laser and the waveguide.

本文从传统几何光学原理出发，用光线追迹的方法来计算研究准直光束斜入射到模折射率透镜上产生的像差，以及当半导体激光器与波导端射耦合以MIL作为准直透镜时，输出准直光束的发散情况，并探讨MIL在集成光学频谱分析仪中作为准直或会聚透镜的适用性。

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.
