Introduce the heavy hammer structure and lock framework with machine combine with solenoid parts of the hydraulic check valve,explatiate on the composing the work principle and character.

The displacement of each mode is determined by a balance between the energy fed into the riser over lock-in regions and the energy dissipated by the fluid damping over the remainder.

From the points of learning figuration,benefit acceleration and resource preference,this paper discusses the causes of lock-in during the course of the construction of start-up enterprise social networks.

The frequency lock-in phenomenon was observed when the reduced velocity is in the range of 4.

The continuity equation and electric-charge balance equation of nonlinear GaAs photoconductive semiconductor switches(PCSS) in Lock-on state were established,in which the current filaments,the velocity-electrical field characteristic with negative differential mobility,the deep level traps and the reabsorption of photons from carrier combination were considered.
