| Abstract: | The article emphatically show general design, principle and function, the system technical direction. Through a year studying, the database system fitted to Heilongjiang province has been built. The database system is able to reasonable, scientific, sophisticated manage remote sensing data. Key words:satellite remote sensing databaseian Huaizhang, Huang Dong, Yang Xiaoguang, Li Xuexun (Xian Jiaotong University, 710049)ABSTRACT:In this paper, a mathematical model of condensation in a cryogenic PH 3 trapper with the presence of a non-condensible gas N 2 is developed, the calculation of the model is carried out and the mechanism of heat and mass transfer is theoretically studied. It also analyses the non-condensible gas N 2's effect on the condensing heat transfer of the PH 3 in the cryogenic trapper to obtain the following three changes by numerically computation:the temperature's change of the gas-liquid film interface with the change of the height of the cryogenic PH 3 trapper, the change of the liquid film's heat resistance and the total condensing resistance of the trapper, the change of the trapper's local heat transfer capacity, the change of heat transfer coefficient of the trapper and the change of N 2's partial pressure. |
