微扰函数 meaning in Chinese

perturbing function

Through the analytic continuation of first order perturbation function in the - plane , we have that the integral path of dispersion equation should use the landau path
。通过将一级微扰函数在整个复频率平面上解析延拓，得到色散方程中的积分路径应采用landau积分路径。
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。
