For desulphurization of sintering gas,a pilot dense flow absorber was built and desulphurization experiment was carried out.

This paper summarizes the current pollution status of SO_2 in steel company and main control technologies, points out the agglomeration gas desulphurization is effective control measure, analyzes characteristics of agglomeration gas, introduces the dense flow absorber desulphurization technology,and makes suggestions for choosing agglomeration gas desulphurization technology.

Identification of micro-fault and sand body by using coherence technique and 3-D visualization.;

Application of coherence technique can facilitate structural and lithological interpretation and shorten exploration term,therefore;3D coherence technique is one of key technique in oil & gas exploration.

This paper will briefly discuss mtethods and principles of coherence technique,a new concept of full 3D seismic interpretation,and applications of the technique in quality appraisal of 3D seismic data,fault interpretation,autotracking and interpretation of seismic events,searching for special geological b.

The coherence cube is a newly 3-D seismic interpretation technology developing in recent years.

The coherence cube technique is an interpretation processing technique,which is used to describe the fault and stratigraphic characteristics.

With the increasing use of optical coherence tomography, the study of the signal-to-noise ratio in low-coherence interferometry has been of increasing concern.
