In this paper, the mathematical model of the reltion between water saturation vapor pressure and saturated temperature is established in the form of monoacidic polynomials.
Objective:to study the chemical constituents of the essential oil of Inula helenium L.were extracted by steam distillation(SD)and supercritical-CO2 fluid(SFE).
The car is powered by compressed hydrogen, which, in combination with oxygen from the air, produces electricity in the car's fuel cell. The only byproduct is water vapor.
