absorption cross-section

基本解释

A radiation line strength database, HITRAN, is used to calculate the standard absorption cross-section.
利用HITRAN数据库中的辐射线强等参数建立了用于浓度反演的标准吸收截面。
When the upper state population is reversed, the channel with greater difference of emission and absorption cross-section has bigger signal gain due to its competitive advantage.
当上能级粒子数处于反转分布态时，具有较大的发射截面与吸收截面差值的波长信道拥有相对较大的竞争优势，可获得相对较高的信号增益；
We propose the coupled-cluster equation of motion method coupled with semiempirical Hamiltonian to calculate the multi-photon absorption cross-section for complex molecular systems.
我们提出了用耦合簇运动方程方法并结合半经验哈密顿参数来计算大分子体系的多光子吸收截面。

吸收截面
They are D- -A model, with large TPA absorption cross-section,πpowerful fluorescence and good upconversion capability.
它们为具有D- -A型的，有大双光子吸收截面，强双光子荧光和上转换能力。

吸收截面
Absorption cross-section of the 6H11/2 and 6H13/2 levels and emission cross-sections of the 2.7 and 4.2μm fluorescences in Dy3+-doped Ge-Ga-S glasses increased with decreasing sulfur concentration.
对得到的Dy3+掺杂的Ge-Ga-S-CsI体系不同组分的硫卤玻璃的6H11／2和6H13／2能级的吸收截面以及掺杂样品在2.7和4.2μm处的荧光发光的发射截面进行比较后发现比较,发现两者都随玻璃系统中S的含量的增加而减小。
