stepping-stone method

Douglas and Dupont deeply discussed the spline collocation methods for nonlinear parabolic: initial-boundary value problems in one space variable. They considered the use of orthogonal collocation method combined with various time-stepping procedures and got, some optimal results.

Douglas与Dupont在文献[1]-[4]中深入讨论了一维非线性抛物初边值问题的样条配置法，他们把正交配置法与各类时间离散方法相结合，得到了很好的结果。

Undr the control of frequency inverter and PLC ( Programmable Logic Controller), the general AC asynchronous motor can function as low rotate speed large torque stepping motor. The working principle, structure, adjusting and testing method of the motor system were introduced.

利用变频器和PLC可编程控制器进行控制，可以将普通交流异步电动机用作低速大转矩步进电机，文章介绍了这种步进电机系统的工作原理、系统构成和调试方法。

This paper proposes a transient analysis method of time-varying RLC network. At first, stepping variation of branch voltage is taken as a unknown variation, and then, the branch voltages and currents in network can be easily found with help of it.

本文提出了一种时变RLC网络的数值分析方法，它首先把支路电压的步进变化量作为待求变量，然后以此可很方便地求出网络中各支路的电压及电流。

In response to this, a slide mode robust control design is presented based on back-stepping method, and a control quantum is obtained through Lyapunov steady theory.
