System dynamics is an approach to understanding the behaviour of systems over time.  It deals with internal feedback loops and time delays that affect the behaviour and state of the entire system.  What makes using system dynamics different from other approaches to studying systems is the use of feedback loops and stocks and flows.  These elements help describe how even seemingly simple systems display baffling nonlinearity.

'''系统动力学 System Dynamics'''是一种理解系统随时间变化行为的方法。它是用来处理影响整个系统行为和状态的内部反馈回路和时间延迟的方法。系统动力学不同于其他系统研究方法的地方在于它使用了反馈环、<font color='red'>股票（stocks）和流形（flows）</font><font color='blue'>存量(stocks)和流量(flows)--[[用户:木子二月鸟|木子二月鸟]]（[[用户讨论:木子二月鸟|原wiki里这两个词指向:https://en.wikipedia.org/wiki/Stock_and_flow ，估计应该是存量和流量的意思，也可以群里大家讨论一下]]）</font>--[[用户:嘉树|嘉树]]（[[用户讨论:嘉树|如何翻译stocks 和 folows]]）的元素。这些元素有助于描述看似简单的系统如何显示复杂的非线性行为。
