扰动振幅 meaning in English
response excursion
Examples
- One of the inequalities is that the initial disturbance amplitude is more than a critical value , and the other is that the frictional coefficient is more than another critical value
初始扰动振幅大于某一临界值； ( 2 )摩擦系数大于某一临界值，前者对后者有很强的约束。 - It follows that the latter imposes a crucial constraint on the former , thus leading to the fact that when the amplitude is bigger compared to another critical value , generalized nonlinear subcritical symmetric instability may occur
由此可见，后一条件对前一条件附加了一个很强的约束，当初始扰动振幅大于另一临界值时，容易出现非线性亚临界对称不稳定。 - Secondly , nonlinear threshold of two - dimensional rt instability was analyzed in planar and cylindrical and spherical geometries . density amplitude was defined relating to instable interface and formulae of nonlinear threshold values for rt instability in three geometries were given , then the lared - s code was used to simulate two - dimensional rt instability in three geometries and simulation results agreed well with the formulae
其次，讨论了二维平面、柱和球几何中rt不稳定性发生非线性偏离的阈值问题，给出了三种几何中密度扰动振幅的非线性闭值公式，并且用lared一s程序进行了检验，计算结果表明柱和球几何中的模藕合机制与平面几何不同，存在几何效应的影响。 - A new kind of generalized energy is proposed as the lyapunov function , and thereby resulting in a new criterion of generalized nonlinear symmetric stability . it shows that not only must the dissipative coefficient be greater than a certain critical value but the initial disturbance amplitude must be synchronously smaller than another marginal value as well
从含摩擦耗散的f平面上boussinesq近似下的非线性方程组出发，提出了一种新的广义能量作为lyapunov函数，导得了一种新的非线性对称稳定性判据：即不仅耗散系数大于某一临界值而且同时初始扰动振幅小于另一临界值。
