Also, it is quite intensive to run UPDATE STATISTICS in the high mode ina production system that runs continually.
而且，在连续运行的生成系统中，以high模式运行UPDATE STATISTICS显得过于密集。

The hydraulic jet pump can reduce the producing cost due to its long run-life, few inspection operation, highproduction efficiency, less power consumption and less usage of power liquid.
射流泵运行周期长、检泵作业量少、生产效率高、耗电量小，动力液用量少，可使采油成本降低。

Debugging and production line run show that this system has many advantages such as reasonable design, high precision, short work time and strong anti-disturbance.
