摘要：
Effects of colored noise on stability of metastable state in logistic model are studied by means of Fox approach and steepest-descent approximation. The expression for mean first-passage time from metastable state to stable state is derived firstly. Based on the expression, we analyze effects of colored noise. Results indicate: that stability of the metastable state always weakens as multiplicative noise intensity and additive noise intensity increase. However, it is always enhanced as self-correlation time of multiplicative noise and cross-correlation degree between multiplicative noise and additive noise increases.
