我们报告的动力学研究的一组完全可解的晶格模型的力诱导的DNA解链过渡。除了产生整个平衡相图，这揭示了一个再入，这些模型使我们能够从一个非平衡初始条件的过程中的动力学特征。DNA的热解链表现出依赖于模型的时间演化。相反，通过力解压缩的动力学机制是非常鲁棒的，并且标度行为与描述的细节无关，因此是超普适的。
We report studies of the dynamics of a set of exactly solvable lattice models for the force-induced DNA unzipping transition. Besides yielding the whole equilibrium phase diagram, which reveals a reentrance, these models enable us to characterize the dynamics of the process starting from a nonequilibrium initial condition. The thermal melting of DNA displays a model dependent time evolution. On the contrary, the dynamical mechanism for the unzipping by force is very robust and the scaling behavior is independent of the details of the description and, hence, superuniversal.
