Vlasov kinetic theory of the FEL with cyclotron maser pump is presented, linear growth rate obtained and two schemes of cyclotron maser pumps are proposed.

The kinetic energy of the oil is comparatively low, and therefore between hydraulic motors and pumps. Any pump may be used as a motor.

在液压马达和油压泵区别不大，任何一个油压泵都可以当作一个液压马达来使用。

This is an application, so most of what today's filing tells us is certainly not set in stone, but new ideas include a "kinetic energy gathering component" within the band -- like the trickle charge feature found on watches -- to pump energy back into the device.
