这种变化趋势的发生部分是因为黑色的水与白色的冰相比，反射效应低，从而吸收了更多来自太阳的热量。
Part of this change is down to the albedo effect, with white, reflective ice replaced by dark water, which absorbs more of the sun's heat.
或许避免在程序执行期间创建这些类的最佳方式在于，避免在应用程序的时间关键型部分使用反射服务来从字符串映射类、字段或方法。
Probably the best way to avoid their creation during the program is to avoid using reflection services to map class, field, or methods from strings during the time-critical parts of your application.
城市街道上，房顶上的绿色植物更多了，这意味着随着水分从叶片上蒸发，会带来更多的清凉；非绿色部分可以涂成白色用以反射太阳光。

Water, usually dark blue in this type of image, is silvery white from reflected sunlight.

Reflecting sunlight also colors the outer edges of the mudflow silver and highlights the texture of the growing mound over the vent at the center of the volcano.
如果一个人站在明亮的窗户前，对面的墙壁会反射部分光线落在人身上。
A person with his back to a bright window will have light reflected from an opposite wall falling on him.
在特定点上，纤维可以向内反射光线，当光线沿纤维传输时，部分会反射到探测器上。
The fiber is internally reflective at specific points, so that when light is sent along the fiber, some of it bounces back to a detector.
这个库中实际的反射代码只代表整个实现的一小部分，因此我将主要关注与反射最相关的一些方面。
The actual reflection code within this library represents only a small portion of the full implementation, so I'll focus primarily on the aspects that are most relevant to reflection.

It is here that you learn how to use composites, create gradients, draw reflections, and apply filters to images.
部分激光经大气中的云和粒子反射，回到卫星。
Some of the light bounces off clouds and particles in the atmosphere and returns to the satellite.
基于模型的反射代理，根据其当前的感知和部分历史采取行动。
Model-based reflex agents, which act based on their current perceptions and partial histories.
雷达信号接触到飞机的任何部位，都会有部分被反射回来。
No matter where the radar signal hits the plane, some of the signal gets reflected back.
在第2部分，我展示了无论是对于字段访问还是方法调用，反射都比直接代码慢很多倍。
Back in Part 2, I showed how reflection is many times slower than direct code for both field access and method calls.
要把光被捕获在两维的曲线状表面上时，要求物体表面非常平滑，才足以把大部分光线干净利落地反射进油层而不是分散在所有的各个角度上。
For the light to be trapped in two dimensions, the object's surface needed to be smooth enough to cleanly reflect most of the light into the oil layer rather than scattering it at all angles.
如果光线被玻璃或者半导体表面反射的话，贴膜会改变其中大部分光线的方向使其重新射回太阳能板。
If light does reflect off either the glass or semiconductor surfaces, the film redirects much of it back into the solar panel.
这样的平面反射了大部分蝙蝠的声波，但是有一部分能量垂直撞击到表面上，声波回传至蝙蝠。
Such surfaces reflect most of the bats' echolocation energy away from it, but some energy hits the surface perpendicularly, sending an echo back directly beneath the bat.
在下一部分，我将提供如何使用反射的更详细实例。
In the next installment, I'll give a more detailed example of how to use reflection.
闪闪发光的银色球的漫反射光线应该是银色的，其镜面反射部分为白色。
The shiny silver ball's diffused color would be silver and its specular component white.
我不打算一一介绍每一个类，因为其中大部分类都与库的反射方面不相关。
I'm not going to go through the whole list here, since most are irrelevant to the reflection aspect of the library.
在图的左下方，从水面反射的阳光使这部分海水表面显现银色。
Sunlight reflecting off the surface of the water is turning the water's surface silver in the lower left corner.
图片中深蓝区域的冰雪反射了大部分能量，其散热作用最明显。
Dark blue areas reflect the most energy, having the greatest cooling effect.
新月抱旧月“只不过就是月球表面上正处于黑夜的那一部分被地球的反射光反照的结果。”
"The old moon in the new moon's arms" is nothing but that part of the moon's surface on which it is night, lighted up by earth light.
在那里或许有些奇怪的化学成分是开普勒望远镜没能看到的。 这个温度太热了不能形成氨云，氨云可以反射一部分入射辐射，如木星上便是如此。
That’s too hot for the formation of ammonia clouds that would reflect some of that incoming radiation as they do on Jupiter.
