有分求助,英语翻译,物理有关。虽然分不多,但希望大家帮帮忙。谢谢了,我有了分会尽量追加的。

内容:
光的吸收:指原子在光照的下,会吸收光子的能量由低能态跃迁到高能态的现象。
一般吸收:若物质对各种波长λ的光的吸收程度几乎相等,即吸收系数a与λ无关,则称为一般吸收.在可见光范围内的一般吸收意味着光束通过媒质后只改变强度,不改变颜色。例如空气、纯气、无色玻璃等媒质都在可见光范围内产生一般吸收。
选择吸收:若物质对某些波长的光的吸收特别强烈,则称为选择吸收。对可见光进行选择吸收,会使白光变为彩色光,绝大部分物体呈现颜色,都是其表面或体内对可光进行选择吸收的结果。

Light absorption: refers to the next atom in the light, will absorb the energy of photons from the low-energy state of transition to the high-energy state phenomenon.

In the visible range of the general absorption means that the beam through the media, only to change the intensity, not change color. 例如空气、纯气、无色玻璃等媒质都在可见光范围内产生一般吸收。 Such as air, pure air, colorless glass medium are generated within the scope of the general absorption of visible light.
选择吸收:若物质对某些波长的光的吸收特别强烈,则称为选择吸收。 Selective absorption: If the substance on the absorption of certain wavelengths of light particularly strong, is called selective absorption. 对可见光进行选择吸收,会使白光变为彩色光,绝大部分物体呈现颜色,都是其表面或体内对可光进行选择吸收的结果。 Selection of the visible light absorption, will become a white color light, most of objects showing the color, are on its surface or in vivo selection that can be light absorbing results.

Light absorption: refers to the next atom in the light, will absorb the energy of photons from the low-energy state of transition to the high-energy state phenomenon.

General absorption material for various wavelengths: if the light is absorbed nearly equal level, i.e. absorption coefficient with independent, called the general status in the visible absorption. Within the scope of the general absorb means only changed after the propagating through medium strength, not change color.

For example, the pure air, colorless optical glass and medium range in general absorption produced.

If you choose to absorb: some wavelengths of light absorption, particularly strong absorption. Choose called Choice of visible absorption, can make the light colored light, become most colors, object is the surface or body to absorb light can choose the results.
