Under the conditions of uncontrolled pH values of 5, 6, 7 and 8, when the microorganisms grew at stationary phase, the hydrolysis rate constants K were 6.

An attempt was made for researching the effect of temperature and pH value on carbetamide hydrolysis rate in buffer solution by means of controlled laboratory method.

The effects of temperature and pH on hydrolysis rate of methylchlorpyrifos were studied by GC-MS.

Quantitative analysis of dissolution rate of limestone used in WFGD;

Assuming that there is a linear relation between dissolution rate and dissoluability and setting the slope of the viscosity-time curve as dissolution rate,the dissolution rate of nitrocellulose(NC) in ethanol-aether mixed solvent in different instance was studied.

The basal properties,application in food industry of neotame and methods to improve the solubility and dissolution rate in water of neotame are detailed in this paper.
