摘要：
The transient properties of a bistable system with time-delayed feedback and non-Gaussian noise are investigated. The explicit expressions of the mean first-passage time (MFPT) are obtained. The numerical computations show that the MFPT of the system is affected by the delay time tau, the non-extensive index q and the color noise correlation time tau(0). That is, q can induce the MFPT from a complex behavior to a simple monotonous behavior with tau increasing (i.e. from two extrema to no extremum). But with the q increasing, the MFPT has a extremum, which is more large as tau increases.
