At low-temperature conditions, concentration and activity of activated sludge and biofilm were found to increase with the increase of recirculation ratio.
在低温条件下,随着反应系统回流比的增大,活性污泥、生物膜浓度以及活性都随着回流比的增大而增加。

当负荷在3～8kgCOD／m~3·d之间时，出水COD浓度在40～170mg／L之间变化，可通过调节回流比的方法，克服COD容积负荷对循环滤池运行效能的影响；高水力负荷下，SS去除效果较差，当回流比从3、5增大到7时，SS去除率从90.6％、86.9％降到76.3％；滤池的运行效能随反冲洗的进行呈周期性变化，运行周期为24h。

Mixture temperature is examined to analysis the effect of the recirculation ratio in the combustion and the inner heat transfer process.
分析了燃烧和内部换热过程带来的不同再循环率下的混合物温度变化。
The annual total cost of optimum design decreased by 20.8% than that of conventional design without EGR, 14.3% than that of conventional design when exhaust gas recirculation ratio was 0.2.
对湿空气出口温度和废气循环比进行优化设计，比无废气循环的常规设计节省年总费用20.8%，比循环比为0.2时的常规设计节省年总费用14.3%。
Schemes of variable compression ratio (VCR), variable exhaust gas recirculation (EGR), variable exhaust valve timing, and EGR with stratification by tumble charge flow are recommended.
