A mathematical description of the photosynthesis light curve is proposed taking into account the type of photosynthetic unit (PSU) organization (unicentral or multicentral), energy migration between the PSU, and the nonlinear character of the dark process limiting the rate. In the case of unicentral PSU the light curve is described by the expression: I = v (1--yv)/(1--v) where I is light intensity; v is relative rate of photosynthesis (relative to the maximal rate); y is the parameter which determines the shape of the curve. Its value depends on the efficiency of energy migration between PSU and on the ratio of the limiting dark reactions rates. The variations of the value from 1 to 0 give different known types of light curves. Coordinates are proposed in which the curves for multicentral and unicentral PSU are distinguished and parameter is estimated. Experimental light curves for a number of marine algae correspond to the supposition of the PSU unicentral organization, with y = 0.9.
考虑到光合单位（PSU）组织类型（单中心或多中心）、PSU之间的能量迁移以及限制速率的暗反应的非线性特征，提出了光合作用光曲线的数学描述。在单中心PSU的情况下，光曲线由表达式I = v (1--yv)/(1--v)描述，其中I是光强；v是光合作用的相对速率（相对于最大速率）；y是决定曲线形状的参数。其值取决于PSU之间能量迁移的效率以及限制暗反应速率的比值。该值从1到0的变化给出了不同的已知光曲线类型。提出了一些坐标，在这些坐标中可以区分多中心和单中心PSU的曲线并估计参数。许多海洋藻类的实验光曲线与PSU单中心组织的假设相符，y = 0.9。
