光线

In this paper, the stray light and ghost image caused by multi-reflection in high power infrared optical systems are analyzed and discussed, and the comprehensive method incorporating paraxial approximation and real ray trace is presented; the data structure of binary tree is used in the storage of interdata so that the storage problem of huge-size data is resolved.

本文主要研究了大功率红外光学系统中光学表面多重反射而形成的杂散光及其数学模型与计算方法，提出了将近轴近似法和有限光线追迹法相结合的综合分析方法；同时在数据存储方式上采用二叉树这种数据结构，巧妙地解决了鬼像分析中海量的中间数据存储的问题。

On the basic of NNLSE and the Poisson equation, using the Green function approach, we obtain the response function of the lead glass of finite-size, which is a strong nonlocal medium. Starting with the paraxial ray equation, we obtain the analytical solutions of the oscillation trajectory and period of the beam.

基于非局域非线性薛定谔方程以及热传导的泊松方程，采用格林函数法求出了强非局域介质铅玻璃的响应函数和临界功率；从光线方程出发得到了偏离材料中心入射的光束中心振荡轨迹以及周期的解析解。

The soft light and its vivid landscape of pastel colors have inspired writers and artists like F.

柔和的光线与带着清淡色彩又生气勃勃的景色已激发了不少画家与作家的灵感，比如F。

What you see is simply light patterned in various ways.

你看见的不过是诸多光线变化的方式。

His work in this direction was motivated by his interest in light and in the design of pendulum clock.

他对光线研究和钟摆设计的兴趣推动了他在这方面的工作。

For centuries, the Lighthouse of Alexandria (occasionally referred to as the Pharos Lighthouse) was used to mark the harbor, using fire at night and reflecting sun rays during the day.

许多个世纪以来，亚历山大的灯塔（有时，也被称作法罗斯灯塔）就成了这个港口的标志，夜间燃火，白天则通过反射光线。

Phew! Jesus-Christ! Light appeared again, but this time in front of us.

哇， 我的妈呀，光线又出现了，而且这次是在我们的正前方！

Instruments used in the study included a photometer, a phonometer, a V8 camera, a heart rate monitor, a respiration monitor, and a blood oxygen saturation monitor.

研究先后测量新生儿加护病房原有包布覆盖状态，包布覆盖保温箱上方、后方和侧边1/3处及移除包布，三个情境保温箱内光线照度、音量、早产儿的心跳速率、呼吸速率及血氧饱和度。

If the display of such lights by the time easy to speed up the longer the aging CRT phosphor, lower luminous efficiency (in the strong light environment, in the face of the display work, our eyes will be extremely vulnerable to damage the screen light reflection).

如果显示器受强光照射，时间长了容易加速显像管荧光粉的老化，降低发光效率（在强光照射环境下，面对显示器工作的人员，眼睛也极易受到屏幕反射光线伤害）。

Because these semiconductor light irradiation, the strong performance of the oxidation capacity, as Photocatalyst.

因为这些半导体在光线的照射下，表现出强大的氧化能力，因此称为光触媒。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
