It was discovered that the leaching concentration of heavy metals from waste catalyst didn't change with the increase of leaching time at unsaturated conditions,but the leaching rate was dramatically increased with the increase of the degree of saturation.

Effects of NaCl concentration on capillary-uptake degree of saturation in concrete,ice-formation pressure and volume expansion of solutions were investigated,and then mechanisms of the deicer-frost scaling of concrete was analyzed.

The degree of saturation under different environmental conditions was investigated.

In order to determine the upper limit of reservoir water saturation, HTHP core test technologies are used for the first time to measure the oil and gas relative permeability of cores sampled from different oil and gas reservoirs at different areas of Sichuan Basin under full modeling conditions.

This apparatus is being widely used to measure the water saturation of reservoir rocks inpetroleum exploration and devolopment.
