An algorithm to detect carrier frequency of DS signals based on blind source separation;

Research on coded digital signal carrier frequency;

Blind estimation of MPSK carrier frequency;

It mainly introduced the algorithm based on the carrier point gas velocity by listing all of the equations,and showed the result of calculation based on the same process conditions under the circumstances of 30 different packing varieties and specifications.

For characterizing non-newtonian fluid flow and heat transfer in mechanically agitated gasliquid vessells, the dimensionless group relationships are proposed on completely gas dispersed area (loading point ).
