高阻尼条件下推导了在加性和乘性白噪声共同驱动下一维周期势中运动粒子的迁移率公式．当周期势为余弦势时，发现：在加性白噪声的基础上，由于周期势幅涨落导致乘性白噪声的加入，使运动粒子的迁移率增大，并且在两个噪声强度一定的条件下，运动粒子的迁移率随周期势幅的增大而减少，直至为零．
Under the condition of high damping, the formula of mobility of moving particles in one-dimensional periodic potential driven by additive and multiplicative white noises is deduced. When the period potential is the cosine potential, it is found that on the basis of additive white noise, the addition of multiplicative white noise due to the fluctuation of periodic amplitude increases the mobility of moving particles, and in the case of two noises with certain noise intensity Under the conditions, the mobility of moving particles decreases with the increase of the periodic amplitude until it reaches zero.
