Using the method of standard limestone tablets,the authors detected the corrosional ratios and average corrosional rates of four different vegetation types on the basis of the observation of karst dist.

t is a new method of studying the water-rock reactions by modeling the reactions and calculating the amount of mineral dissolution between groundwater and rock by the means of liner programming.

Electroinduced-swelling/erosion behaviors of ioncally crosslinked polyampholyte hydrogel;

Matrix erosion and water uptake were performed to elucidate the mechanisms of calcium chloride on drug release.

The swelling rate was 150% in water for injection and the 24h erosion rate was about 60% in saline.

Control of calcareous sandstone dissolution on rock mass quality in an hydroelectric station on the Jinsha River;

The speciality of gypsum dissolution of the Neogene red clay and its influence to engineering;

Repeated practices and understandings reveal that a mature gas field having been developed for 10 years is a secondary gas pool, with reservoir and seal occurring in the same strata of gypsum-dissolution cavernous-fractured argillaceous rock resulted from modern weathering and dissolution and containing gas migrating upward from the underlying gas pools and from hydrocarbon sources.

To prevent the corrosion of rock minerals with the ternary combination system during flooding, an effective method for stopping the dissolving of silica under strong caustic condition is presented.

In connection with practical engineering of2 0 0 m roll compacted concrete dam,this paper describes the stability of permeable corrosion of flyash concrete.

,it is considered that the pore type is main as secondary pore,which consists of enlarged solutional void,intergranular solutional void,extracted fracture,and extracted corrosion fracture etc.
