1、Along with radius of three cavitations bubbles reducing, the intensity of pressure to rigid wall is strengthened gradually.

2、A kind of easy and convenient method judging intensity of pressure changing the shift of chemical equilibrium--The method of the same bracket canceling out each other;

3、The distributing of intensity of pressure is determined when polished die is baring partly and the controlling means of edge effect are generalized.

4、Because FRP jacketed concrete columns can greatly increase columns intensity of pressure, they have become the new hotspot in the structure reinforced field.

5、And the high-pressured active bend use high density steel manufacture after the heat treatment, can guarantee the fixed work intensity of pressure like this, extension service life.
