体吸收系数 meaning in Chinese

volume absorption coefficient

First the emission spectrum of an atom in a grey - body cavity is stuided . the influences of the incident field photon - number distribution , the cavity absorptivity and the system temperature on the atomic emission spectrum are discussed in detail . it is found that the influence of cavity radiation on the atomic emission spectrum could be reduced through diminishing the absorptivity of the cavity and lowering the temperature of the cavity
我们首先研究了灰体腔中二能级原子和型三能级原子的发射谱，详细讨论了入射场光子数分布、腔体吸收系数以及系统温度对原子发射谱的影响，指出在实验上可以通过减小腔体吸收系数、降低系统温度来减小腔体辐射对原子发射谱的影响。
