摘要
Based on our previous attempt, we propose a better way to understand a small but nonzero cosmological constant, as indicated by a number of recent observational studies. We re-examine the assumptions of our model of two scalar fields, trying to explain the basic mechanism resulting in a series of mini-inflations occurring nearly periodically with respect to In t with t the cosmic time. We also discuss how likely the solution of this type would be, depending on the choice of the parameters.
