To James, steady attention was thus the default condition of a mature mind, an ordinary state undone only by perturbation.
对于James来说，稳定的注意力是成熟个体的普遍特征，普通状态被打破只能源于混乱。

A method of opening force analytical model was brought forward to solve the dynamic response analysis to pressure perturbation under the steady status.
提出了一种“开启力解析模型”的方法来求解稳态下密封性能对压力扰动的动态响应。

Perturbation method is used to obtain the bifurcation equation with time-delays, and numerical method is utilized to analyze the effect of time-delays on the steady state response.
