| 摘 要： | 推导一维周期势中在关联加性和乘性白噪声驱动下运动粒子迁移率公式。通过对余弦势中运动粒子迁移率的讨论，得到在朗之万方程中由于乘世噪声项的加人，使余弦势中运动粒子的迁移率增大；当噪声之间存在关联，则余弦势中运动粒子的迁移率减少。

| Abstract: | We derive a formula of mobility about particles driven by correlated white noises in certain case. Addi tionally,the result of this example denotes that the mobility of motive particles increases because of presence of the multiplicative white noise,but the mobi1ity of motive particles decrease when the white noises is correlation in the co sine potential. |
