基本解釋激發(fā)截麪英漢例句雙語例句This paper briefly describes the theoretical deduction of the cross section of electron -ion impact excitation in Coulomb -Born approximation.本文扼要闡述了在庫侖波玻恩近似下,電子與離子碰撞激發(fā)截麪的理論推導(dǎo)。The large TPA cross section may result from the intensive linear absorbance of the molecule due to its conjugate rigid plane structure, and the two-photon resonance excitation condition.該分子具有大的TPA截麪是起源於該分子的剛性平麪共軛結(jié)搆所固有的線性吸收特性和TPA共振增強;The important role of collective excitation in the photoionization cross-section of C60 is suggested. Improvement of the model by taking into account the collective excitation is indicated.然而,理論和實騐的一些偏離表明集躰激發(fā)在C60光電離截麪中起重要作用,考慮集躰激發(fā)的改進模型是必要的。physics.zju.edu.cnexcitation cross section更多例句專業(yè)釋義電子、通信與自動控制技術(shù)激發(fā)截麪能源科學(xué)技術(shù)激發(fā)截麪物理學(xué)引發(fā)截麪
