In a [[dynamical system]], '''multistability''' is the property of having multiple [[Stability theory|stable equilibrium points]] in the [[vector space]] spanned by the states in the system. By mathematical necessity, there must also be unstable equilibrium points between the stable points. Points that are stable in some dimensions and unstable in others are termed unstable, as is the case with the first three [[Lagrangian points]].

在动力学系统中,多重稳定性是在矢量空间中具有多个稳定的平衡点的特性,该平衡点由系统中的状态跨越。根据数学上的必然性,在稳定点之间也一定存在不稳定的平衡点。 与前三个拉格朗日点一样,在某些维度上稳定而在其他维度上不稳定的点被称为不稳定点。

Bistability is the special case with two stable equilibrium points. It is the simplest form of multistability, and can occur in systems with only one state variable, as it only takes a one-dimensional space to separate two points.
      
双稳态是具有两个稳定平衡点的特殊情形。这是多重稳定性的最简单形式,可以发生在只有一个状态变量的系统中,因为它只需要一个一维空间来分隔两个点。

多稳态知觉是一种较少见的视知觉现象。多稳态知觉常被描述为在观看一图形时,会主观性的观察到图形无法预期的自发性改变,并且这改变会接续不断发生。

当一个图形对人类的视觉系统来说,是具有歧义性时,就会引发多稳态知觉的现象。如一些知名的例子如奈克方块Necker cube、运动中探知结构(structure from motion)、单眼竞争(monocular rivalry)和双眼竞争binocular rivalry。但更为人所知的是暧昧图形(ambiguous image)。因为这些图形通常会在两种知觉状态之间相互交换,所以又称为双稳态知觉。通过横向抑制,其中一个图像在受到刺激时会抑制邻近图像的活动。<ref>{{cite journal | url = http://neuro.bcm.edu/eagleman/papers/Eagleman.NatureRevNeuro.Illusions.pdf | title = Visual Illusions and Neurobiology | last = Eagleman | first = David | journal = Nature Reviews Neuroscience | date = 2001 | volume = 2 | issue = 12 | pages = 920-926 | doi = 10.1038/35104092 | deadurl = yes | archiveurl = https://web.archive.org/web/20070927212714/http://neuro.bcm.edu/eagleman/papers/Eagleman.NatureRevNeuro.Illusions.pdf | archivedate = 2007-09-27 }}</ref>
