这由滞后作用当前砍典型地达到依照被说明。
This is typically achieved by hysteresis current chopping as illustrated.
滞后作用的存在，不但影响降雨过程中的入渗特性，而且影响产流量。
Hystersis influences infiltration characteristics and runoff volume during the process of rainfall infiltration runoff.
但摩擦力(滞后作用)可以保证更平稳地完成油门设定，并缓解在持续挤压弹簧过程中产生的张力。
But the friction (hysteresis) makes it easier to maintain a steady throttle setting, and relieves strain from pushing against the spring continuously.
