| 摘 要： | 研究了交叉关联噪声驱动的双稳系统的瞬态性质。计算了平均首通时间，发现系统的平均首通时间受噪声关联时间和关联强度的影响，关联时间和关联强度的作用相反，即平均首通时间随关联强度增加而增加，平均首通时间随关联时间增加而减少。

| Abstract: | The transient properties of a bistable system driven by cross-correlated noises are investigated.The explicit expression of the mean first-passage time (MFPT) is obtained.From numerical computations is found the following.The MFPT of the system is affected by the correlation time τ and the correlation strength λ and,τ and λ play opposing roles in the MFPT,i.e.the MFPT increases as λ increases and the MFPT decreases as τ increases. |
