耦合角 meaning in Chinese

coupling angle

( 1 ) effects of externally applied electric fields on photorefractive two - beam coupling are analyzed . theoretic dependence of the intensity gain factor on applied field e0 in sbn : 60 is presented . and the experimental results obtained in two sbn : 61 : cr crystal samples with different dopant concentration show clearly that for properly applied fields , a larger f can be achieved effectively than that obtained with no field applied
由两块不同掺cr浓度的sbn 61 cr晶体得到的实验结果同时表明，适当的外电场作用能够有效提高晶体的二波耦合增益，并且，外电场的作用使晶体的响应速度大大提高，而晶体的最佳耦合角与外电场之间没有明显的依赖关系。
