absorption cross-section

基本解釋

A radiation line strength database, HITRAN, is used to calculate the standard absorption cross-section.
利用HITRAN數(shù)據(jù)庫中的輻射線強等參數(shù)建立了用于濃度反演的標準吸收截面。
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.
當上能級粒子數(shù)處于反轉(zhuǎn)分布態(tài)時，具有較大的發(fā)射截面與吸收截面差值的波長信道擁有相對較大的競爭優(yōu)勢，可獲得相對較高的信號增益；
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.
我們提出了用耦合簇運動方程方法并結(jié)合半經(jīng)驗哈密頓參數(shù)來計算大分子體系的多光子吸收截面。

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.
對得到的Dy3+摻雜的Ge-Ga-S-CsI體系不同組分的硫鹵玻璃的6H11／2和6H13／2能級的吸收截面以及摻雜樣品在2.7和4.2μm處的熒光發(fā)光的發(fā)射截面進行比較后發(fā)現(xiàn)比較,發(fā)現(xiàn)兩者都隨玻璃系統(tǒng)中S的含量的增加而減小。
