光线

And no wonder: for Satan transformed himself into an angel of light, and they imitate their master.

也难怪：撒旦转化为自己变成一个天使的光线，并模仿他们的主人。

When the angel of light falling on a mirror changes, what happens to the angle of the reflected light?

当落在镜子上的光线的角度发生变化，反射光的角度会怎么样？

Based on measuring data of relative solar irradiance on absorbers with cylindric shapes in evacuated collector tubeas well as that of solar absorptivity changing with incident angles on the coating,this paper has analyzed and investigated regular patterns of energy gain factor changing with incident angle at different center to center distances of ECT with cylindric absorbers.

在实验测定吸热板表面相对太阳辐照度和涂层太阳吸收比的基础上，分析研究了具有圆柱形吸热体的真空管集热器，在不同管中心距下的能量收益因子随光线入射角的变化规律。

the conditions of acquisition of minimum deviation is proved by means of rolle's theorem and the reversibility principle of beam path for triple prism, it is that the angle of incidence is equal to the angle of emergence for monochromatic incident beam.

利用数学中的罗尔中值定理及光路的可逆性原理证明了三棱镜获得最小偏向角的条件，即单色光线的入射角等于出射角。

Angle of Incidence The angle between an incident ray and the normal to a reflecting or refracting surface.

入射角度入射光与照射在反射或折射平面上的正常光线之间的角度。

Especially prominent here is the performance of trees, in the light irradiation under the sway in the breeze, the leaves keep the posture of the swing, with the angle of reflection of light changes, the entire tree to show the feeling of dreamy people like in the wizard world.

这里尤其突出的是树木的表现，在光的照射下，在微风的吹拂下，树叶不停的摆动着身姿，随着反射光线角度的变化，整个树木表现出梦幻般的感觉，让人犹如在精灵的世界里。

The Law of Reflection states that the angle of reflection of a light ray is equal to the angle of incidence.

反射定律为光线的反射角等於入射角。

The angle of refraction, r, is the angle between the refracted ray and the surface normal.

折射角 r 是折射光线和表面法线间的夹角。

However, determination of an angle of refraction for a ray passing through a boundary between transparent and stronglyoptically-absorbing media is still quite difficult.

这一定律被广泛应用于透明物质，但应用在金属吸收介质(即光线通过吸收介质/介质边界)时的情况，至今仍是一个未被很好解决的难题。

In solar power generation, the angle of the battery plate facing sun and sunlight is a key factor determining the efficiency of solar power generation.

在太阳能发电中，电池板受光面与太阳光线的角度是决定太阳能发电效率的关键因素。

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。
