比气体常数 meaning in Chinese

specific gas constant

In chapter 2 , the meteorological knowledge , data and the methods of the data processing , related to the study on the atmospheric loads , are simply presented . the model for the perfect gas constant , describes by the relative moisture , is developed . the influences of the variation in the vapor component in the atmosphere on the perfect gas constant are evaluated by using the changing characteristics of the temperature on the surface , its spatial gradient and the barometric pressure
