light-exposure and light-and-water-exposure apparatus 光线暴露及光线与水暴露设备
The lack of light explains why spectrometers — instruments that can be used for remote water detection but rely on reflected light to do so — never picked up on the water.
这就很好地说明了我们使用光谱仪,利用物质反射光波,可遥控探测到水分子,但是由于缺少足够阳光,一直没有成功收集水。
When sunlight hits water at the same Angle as a satellite's view, smooth areas reflect light like mirrored surfaces while rough regions scatter light and appear darker.
当阳光从卫星拍照的角度照射到水面上时,平滑的水面像镜面一样反射光线,而不平的水面则会散射光线,看上去是黑暗的。
The area has been described as a kind of oceanic desert, with light winds and slow moving water currents.

Just like we see destructive interference with water waves or with light waves, we can also see destructive interference with orbitals.
就像我们看到水波,和光波的相消干涉,我们也可以看到轨道的相消干涉。
And if we see it, appreciate it, we water it, we shed a light to it, and it appreciates, it grows.
只要我们看到它,欣赏它,灌溉它,播撒阳光,它就会感恩,成长。
