论文摘要
研究了限制在光滑的波纹通道中具有不对称电势和高斯有色噪声的自前线椭圆形颗粒的定向运输。讨论了系统对系统的影响，潜在噪声和彩色噪声。大X轴噪声强度抑制了传输。导向的传输速度随着Y轴噪声强度的增加而具有最大值。适当的瓶颈尺寸适合椭圆形颗粒的定向运输，但是大小的瓶颈大小可抑制这种定向运输。转运反向现象以增加的负载和自旋转速度而出现。与针状椭圆形粒子相比，完美的球体粒子更容易导向传输。
Directed transport of self-propelled ellipsoidal particles confined in a smooth corrugated channel with asymmetric potential and Gaussian colored noise is investigated. Effects of the channel, potential and colored noise on the system are discussed. Large x axis noise intensity inhibits the transport. The directed transport speed has a maximum with increasing y axis noise intensity. Proper size of the bottleneck is good for the directed transport of the ellipsoidal particles, but large and small size of bottleneck inhibits this directed transport. The transport reverse phenomenon appears with increasing load and self-propelled speed. Perfect sphere particle is easier to directed transport than needlelike ellipsoid particle.
