The effects are analyzed on the point to multipoints system of the parameters such as switch congestion threshold, switch output buffer storage, ABR rate increasing factor (RIF) and ABR rate decreasing factor (RDF) in ABR point to multipoints communication.

First, the constant-speed stage during the phase separation of aqueous two-phase system in static circumstance was properly hypothesized, and the framework of the rising rate model for dispersed phase droplets was established via mechanical analytical method.

The algorithm can extracts datatransform velocity gene on line,identifies sampling periods in term of it,and then demodulates sampling data.

Five kinds of density methane was selected and tested in the horizontal pipeline gas exploding device to research the change rule of the maximum explosion pressure,the maximum rate of pressure rise and the arrival peak time with the methane concentration and propagation distance.

Based on three important parameters such as weight of hydrological zones (HZ), depth to water (DTW) and rate of rise(RR), a hydrological response units (HRU) map 2001 was created in the Tao’er River basin, Songnen plain, which can response sensitively to the spatial change of groundwater environment, and it is produced by the algebraic multiplication of the three classified grids: HRU = DTW*RR*HZ.
