It is known that illumination of the algae Chara corallina results in the formation along the membrane of regions with inhomogeneous distribution of pH. It was shown that, in a particular range of illumination intensities, two states with different pH distribution are realized at one and the same value of light intensity: an entirely homogeneous state and completely formed structures (pattern). The transition from the homogeneous state to the pattern formation takes place at one value of light intensity, and the back transition, at another light intensity, i.e., the hysteresis is observed. This phenomenon was studied by mathematical modeling. The mechanism of hysteresis is discussed.
已知对珊瑚轮藻进行光照会导致沿膜形成pH分布不均匀的区域。结果表明，在特定的光照强度范围内，在同一光照强度值下会出现两种具有不同pH分布的状态：完全均匀的状态和完全形成的结构（图案）。从均匀状态到图案形成的转变发生在一个光照强度值处，而反向转变则发生在另一个光照强度处，即观察到滞后现象。通过数学建模对这一现象进行了研究，并讨论了滞后现象的机制。
