The magnetorotational instability is believed to play an important role in accretion disc physics in extracting angular momentum from the disc and allowing accretion to take place. For this reason the instability has been the subject of numerous numerical simulations and, increasingly, laboratory experiments. In this review, recent developments in both areas are surveyed, and a new theoretical approach to understanding the nonlinear processes involved in the saturation of the instability is outlined.
磁转动不稳定性被认为在从盘中提取角动量并允许吸积发生的吸积盘物理中起着重要作用。出于这个原因，不稳定性已经成为许多数值模拟的主题，并且越来越多的是实验室实验。在这篇综述中，调查了这两个领域的最新发展，并概述了一种新的理论方法来理解不稳定性饱和涉及的非线性过程。
