We find that when the collapsing bubble approaches its minimum radius, a high pressure layer just outside the bubble is generated which gradually moves outward and subsequently forms a shock wave.
The experiments of the pressure transients accompanying the growing and collapsing of gas bubbles and cavitation in low pressure hydraulic pipelines are carried out.

The CT held by the gripper blocks is loaded by axial force, pressure of inner fluid and gripping force, and its forcing state influenced setting depth and the ability of anti-collapsing.
