二能级介质 meaning in Chinese
two-level medium
Examples
- The dissertation can be divided into two parts : the control , synchronization of drefls and its application ; optical spatiotemporal pattern in a ring optic cavity
全文分为两大部分：掺铒光纤激光器的混沌超混沌的控制、同步及其应用，二能级介质的光学时空斑图。 - In part two , the optical spatiotemporal pattern in ring optic cavity is investigated . using delay feedback with spatial perturbation method , the system shows roll , square , hexagon , homocentric circle , " honeycomb " and " snowflower " pattern with different spatial perturbation functions . different patterns can be coexist and compete each other with the same perturbation function , which is the new character of this optical system with delay feedback
第二部分，利用延时反馈的空间微扰方法研究了环形腔中二能级介质的光学时空斑图的控制，在不同的微扰函数作用下，出现了滚筒状、四方形、六角形、蜂窝状、同心圆以及“雪花”状等不同的斑图，并且在相同的微扰函数下张胜海:博士学位论文出现了不同斑图之间的竞争，这种竞争是我们发现的这一具有空间微扰的延时反馈非线性光学系统光学斑图的新特征。 - In this dissertation , we mainly investigate the control and synchronization of chaos / hyperchaos in dual - ring erbium - doped fiber lasers ( drefl ) and optical spatiotemporal pattern of medium with two energy levels in a ring optic cavity . at the same time , we also do a pilot study for the application of the synchronization of the chaotic drefls in secure communication
本文主要研究了双环掺铒光纤激光器的混沌超混沌及其控制与同步和环形腔中二能级介质的光学时空斑图，同时对双环掺铒光纤激光器的混沌超混沌同步在保密通讯中的应用做了初步研究。
