滞后滞后Hysteresis滞后(hysteresis)一种物理现象，其中两个(或两个以上)物理龙间存在一种与先前历史有关的依赖关系。更确切赶说，对于一个增加着的输人量X和减小着的X，羊不同的Y对应值。如果将X在某一范围内变化一个周期，由y又x作图得到一封闭的曲线，这个曲线称为滞后匡线。响应量丫滞后于输人量X。在许多科学领域中都有滞后现象。磁性材料莺许是最主要的实例，其中常用H(磁场)作原变董而B(磁感)作应变量。对于选用这样一对变量，碌滞回线的面积具有特殊的意义.即每一周期单位侧 一扩兴姗\帜十︶长侧 高度(%)黄铜单晶的应力一应变(形变)图。正的和负的应变分别 对应于拉伸和压缩积的能量转换成的热量。同样，每一周期单位体积的介电能量损耗可以用E(电场)和D(电位移)来求得。至于力学滞后，惯用的变量为应力和应变(见图)，每一周期的能量密度损耗与内耗有关。在非连续的质点力学中，每个周期的能量损耗是用外加应力和质点位移的滞后回线来给出。热滞后是许多系统都具有的特征，特别是那些有相变的系统，但在这种情况下滞后的回线通常和能量损耗没有什么联系。参阅“铁电”(ferroeleeries)、“磁滞，，(magnetiehysteresis)、“热滞，，(thermal hysteresis)各条。滞后与微观不可逆性密切相关。在电学和磁学中，有序结构中畴壁的运动受阻于母体中的微观不均匀性，并在增加着的应力作用下捕获然后释放。这样的效应显然是不可逆的，在磁学上有巴克好森噪声(B arkhousen noi*)为证。另一方面，任何畴的旋转基本上都是可逆的，对滞后损耗没有贡献。在力学中，位错的钉扎和去钉扎也产生滞后。参阅“晶体缺陷”(erystaldefeets)、“畴，，(domain)各条。与历史无关的响应量Y在输人量X加人之后，在一定时间内达到最终平衡值。这样的时间效应比较复杂，通常不能称为滞后效应。然而，频率与系统自然频率相当的周期实验(共振和驰豫)，其X对Y关系将呈现出滞后的形式，当外加频率与共振或弛豫频率接近一致时，滞后回线内的面积达到最大值。仁亨廷顿(E.B.Huntington)，麦克龙(R.K.MacCrone)撰〕
