derive obtain

Augmented mass, damping, stiffness matrix of system was set up to derive vertical dynamic differential equations for locomotive components and obtain output responses of suspensions.

为建立机车各部件的垂向动力学微分方程，计算各悬挂力的输出响应，建立了系统质量、阻尼和刚度的增广矩阵。

By recursive method and Martingale method, we derive the integral equation for the survival probability and obtain the exponential inequality for the ruin probability.

本章主要通过递推方法和鞅方法得出生存概率所满足的积分方程以及破产概率上界。
