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。

Question

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。

Content:
The absorption of optical:It indicates that the atoms will absorb the energy of photon and transfer from low-energy state to high-energy state when they are illuminated.

General absorption:If the absorption extent of various lights with wavelength λ are equal ,that is to say the absorption factor has nothing to do with λ ,it's called general absorption.It denotes that the beacon of light just changes its intensity with the general absorption in the visible light range,and it doesn't change its color.For example ,air ,pure gas ,flint glass etc can occur the general absorption in the visible light range.

Selective absorption:when the materials has a fairly strong absorption of some particular wavelength light, it's called selective absorption.The white light will become colorama when it conducts the selective absorption,it suggests that numerous substances emerge their color because their surfaces or internals conduct the selective absorption to light.
