[0002] Gas mixing refers to the mixing of two or more effective components, or gases that are ineffective components but whose content exceeds the specified limit. A mixture of several gases is a commonly used working fluid in engineering. Mixed gases are usually studied as ideal gases. The properties of a mixed gas depend on the types and components of the constituent gases. There are three ways to express the composition of a mixed gas, including volume composition: the ratio of the partial volume of the constituent gases to the total volume of the mixed gas. The so-called partial volume refers to the volume occupied by the constituent gases alone at the temperature and total pressure of the mixed gas; mass composition: the ratio of the mass of the constituent gases to the total mass of the mixed gas; molar composition: mole is the unit of amount of substance;
