作用量 Action (physics)(重定向自Action principle)
在物理学里,作用量(英语:action)是一个很特别、很抽象的物理量。它表示着一个动力物理系统内在的演化趋向。虽然与微分方程序方法大不相同,作用量也可以被用来分析物理系统的运动,所得到的答案是相同的。只需要设置系统在两个点的状态,初始状态与最终状态,然后,经过求解作用量的平稳值,就可以得到系统在两个点之间每个点的状态。

Action (physics) 作用量(重定向自Action principle)
In physics, action is an attribute of the dynamics of a physical system. It is a mathematical functional which takes the trajectory, also called path or history, of the system as its argument and has a real number as its result. Generally, the action takes different values for different paths. Action has the dimensions of [energy]·[time] or [momentum]·[length], and its SI unit is joule-second. |
