傍轴方程 meaning in Chinese
paraxial equation
Examples
- In the case of ultrashort laser pulse , the effect of finite pulse length is anlyzed , and self - steepening in the front of the pulse will occur when only relativistic nonlinearity is considered
同时，对于超短脉冲传输，分析了有限脉冲宽度效应对傍轴方程的修正，当只考虑相对论性非线性效应时将会引起激光脉冲前沿自陡峭。 - To deal with the case of 2 dimension spatial self - focusing , it predicts the catastrophic collapse of a self - focusing beam in a kerr medium . this un - physical collapse is due to the invalidity of the paraxial wave equation in the neighborhood of a self - focus
在该理论应用于空间二维的自聚焦时，出现了光束将无限聚焦的结果，这在物理上是不可想像的，原因是在自聚焦点附近傍轴方程已经失效了。 - Chapter 3 : the source - dependent expansion ( sde ) method for analyzing the wave equation is introduced , which is an effective method for solving the paraxial wave equation with nonlinear source terms . two examples have been given to explain this method , which are the propagation of the ultrashort intense laser pulses propagation in the partially stripped plasma in which the collisions of plasma electrons are taken into account , and the propagation including the finite pulse length effect
第三章：本章介绍了求解有非线性源项的傍轴方程的有效方法-源展开方法，并给出了两个具体的例子，即考虑等离子体电子间碰撞的隧道传输的求解和考虑激光脉冲的有限脉宽效应的隧道传输求解。
