uv light

基本解釋

There are two types of UV light that can harm your skin — UVA and UVB.
太陽光線中有兩種紫外線會對你的皮膚造成傷害，即UVA和UVB。
This type of stress, known as oxidative stress, is caused by exposure to cigarette smoke, UV light and pollution.
這種外力來源叫做氧化應激，主要是因暴露于香煙、UV光線以及污染等引起的。

Under UV light, clean sand appears purple or black. Some minerals, such as calcium carbonate in seashells, glow blue, as does a shovel handle in the picture above.
紫外線照射下，干凈的沙子呈紫色或黑色。有些礦物，如海貝中的碳酸鈣，會閃著藍光，就如同上圖中的鐵鍬的把手。

OK, so we've got UV light here, and let's see what we can see, and we lose electrons, if that's what's happening.
好了，我們已經有了紫外光源，讓我們來看看能觀察到什么，如果那些事情發(fā)生了，我們將會失去電子。

We know that UV light gets absorbed by glass, so it shouldn't be able to go through the glass.
我們知道紫外光會被玻璃吸收，所以它無法通過玻璃。

So that means we're going to need to figure out what is the energy per photon that's emitted by that UV light.
所以那意味著我們將需要,計算出從紫外光源發(fā)射出的,每個光子的能量。

紫外光
Due to the wide bandgap (3.2 eV for anatase), TiO2 can only absorb UV light.
由于TiO2的帶隙較寬(銳鈦礦3.2 eV),所以只能吸收紫外光。

Weathering in summer,the UV light intensity and high temperature speed up the evaporation rate of oil,which is beneficial to weathering.
夏季風化時,高輻射強度的紫外線光照和高溫加快溢油蒸發(fā)速率,有利于風化進行。
