【Abstract】 This paper is our theortical studies about the method of the pressure stimulated by gas injecting (PSG1),which was desiganted as the most suitable candidate applicable to the Chinese communication satellie for measuring liquid propellants remainings.Two main thermodynamical models,the isothermal model and the adiabatic model,were set up and the dominant equations corresponding to the models were derived for practical measurement usage. Some problems associated with practical operations were discussed.更多还原
