But when the pressure is bigger than 30MPa, there is a contrary phenomenon. The flow rate, particle size distribution and void fraction of the extraction bed have the complicated effect. 3Based on the broken-intact cells model, a dynamic model based on differential mass balance equation is developed according to the law of conservation mass. The expression of mass transfer flux is given by the analysis the process and the necessary hypotheses. The extraction process is described, and the expression of extraction rate of diosgenin is given.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
