摘要：

With an improved version of our model for inclusion of temperature into Davydov's model using the /D2> ansatz state we surveyed the parameter space of the Hamiltonian. Solitons were found to be stable at 300 K under certain conditions on the parameter values which may be fulfilled in proteins. It is numerically shown that our results agree with those of special versions of Langevin-equation models. Also agreement with recently published perturbation theoretical results is found.
