Dynamic damping ratio of frozen soil decreases with increment of frequency or decrement of temperature.
冻土的动阻尼比随频率的增加或温度的降低而减小。
2
Increasing the back flush frequency reduces the irreversible membrane resistance increment, slows down the flux decline and improves the velocity of net water production greatly.
增加在线反冲洗频度降低了不可逆膜阻增量，有效提高了净产水速率。
