The kinetics of the delayed luminescence arising from correlated coherent many-soliton states in low-dimensional macromolecular systems, is calculated and shown to be different from the one arising from independent soliton states. The correlation between coherent electron states is essential at relatively high levels of excitation in the presence of very long macromolecules in a system. These conditions can be fulfilled in such biological systems, like algae Acetabularia Acetabulum. The cytoskeleton of this unicellular alga contains macromolecular structures (actin filaments, microtubules, etc.) of the length of several hundreds angstroms and more, in which many-soliton coherent states can exist. Indeed, the correlated coherent model is shown to give better fit of the experimental data for this type of algae in a wide range of intensities of the stimulating light, as compared with the model of noncorrelated solitons. The nonlinearity of the dependence of delayed luminescence intensity on the level of excitation increases with the increase of correlation between solitons.
计算了低维大分子系统中由相关相干多孤子态产生的延迟发光动力学，结果表明其与独立孤子态产生的延迟发光动力学不同。在系统中存在非常长的大分子且处于相对较高激发水平时，相干电子态之间的相关性至关重要。这些条件在诸如藻类伞藻这样的生物系统中可以实现。这种单细胞藻类的细胞骨架包含长度达数百埃及以上的大分子结构（肌动蛋白丝、微管等），其中可能存在多孤子相干态。实际上，与非相关孤子模型相比，相关相干模型在很宽的激发光强度范围内对这类藻类的实验数据拟合得更好。延迟发光强度对激发水平的依赖关系的非线性随着孤子之间相关性的增加而增强。
