通过DB CFG参数self_tuning_mem启用STMM之后，您可以让DB 2根据工作负载的波动调优内存结构。
By enabling STMM through the DB CFG parameter self_tuning_mem, you can let DB2 tune memory structures depending upon fluctuations in workload.
为了可靠运行，必须降低转速的波动，即必须有效抑制负载转矩脉动和电机电磁转矩脉动带来的转速波动。
In order to have a reliable operation, must reduce the speed fluctuation, namely must effectively restrain the load torque ripple and motor electromagnetic torque ripple of speed fluctuation bring.
由于我司生产的抓斗阀组带压力补偿功能，流量跟外负载无关，速度不随负载波动。
The valve group is provided with the function of pressure compensation, which keeps the speed stable, not influenced by external load.
