The main study contents include:(1) the calculating programs,the change laws of CO_2 compressibility factors and their effect on CO_2 adsorption in coal;(2) experimentally analysis and theoretically investigation for measurement parameter on CO_2 adsorption;(3) the effect of coal swell caused CO_2 adsorption and water in coal on CO_2 adsorption.

Direct separation and purification of hemoglobin from fresh bovine hemolysate were studied with expanded bed adsorption.

Tests on swelling deformation of expansive soils;

Effect of swelling deformation on stability of expansive soil slope

This paper founds the relation of porosity, permeability and swelling deformation under considering swelling deformation made by coal adsorption gas, and by analysis it can be concluded that as gas stress in the coal bed increases, the swelling deformation becomes bigger, the porosity being much smaller, so as to weaken the permeability of the coal bed and make it difficult for gas flow.

Two models of steel slag filled-up road embankment are made to simulate their dilatancy.

Experimental research on expansive deformation of tertiary red sandstone in Nanjing;

Based on the measuring results of expansive deformation of self-stressing concrete reinforced with various ratios of reinforcement as well as steel fiber volume fractions at the ages from 1 day to 28 days, the different phases of expansive deformation with the age were investigated.

Addition to initial expansive rate and final expansive deformation,half-value time of expansive deformation process was employed to construct the mathematical property set of deformation-time model.
