迟滞现象 Hysteresis

(重定向自Hysteretic)

迟滞现象(Hysteresis),或称滞回现象滞后现象,指一系统的状态(主要多为物理系统),不仅与当下系统的输入有关,更会因其过去输入过程之路径不同,而有不同的结果。换句话说,一系统经过某一输入路径之运作后,即使换回最初的状态时同样的输入值,状态也不能回到其初始。例如一块黏土放在手上,捏压之后不再施力,此时受力与先前放在手上可视为相同,但是却已不是先前形态了,而不同捏压的方法,也会得到不同的形态。 常见的物理迟滞如:磁滞现象、电迟滞现象、弹性迟滞、液固相变迟滞、接触角迟滞现象等。

Hysteresis 迟滞现象

(重定向自Hysteretic)
Electric displacement field D of a ferroelectric material as the electric field E is first decreased, then increased. The curves form a hysteresis loop.
Sharp hysteresis loop of a Schmitt trigger
Elastic hysteresis of an idealized rubber band. The area in the centre of the hysteresis loop is the energy dissipated due to internal friction.
Theoretical model of magnetization m against magnetic field  h. Starting at the origin, the upward curve is the initial magnetization curve. The downward curve after saturation, along with the lower return curve, form the main loop. The inte****ts hc and mrs are the coercivity and saturation remanence.

Hysteresis is the time-based dependence of a system's output on present and past inputs. The dependence arises because the history affects the value of an internal state. To predict its future outputs, either its internal state or its history must be known. If a given input alternately increases and decreases, a typical mark of hysteresis is that the output forms a loop as in the figure.
