【Abstract】 The dynamic mathematical models of compressible gas flowing in the units of the pipe lines system have been conducted separately in this paper.These models have been used to build an entire pipe lines system.The more precise dynamic mathematical models of the proportion adjusting, the vessel pressure adjusting and the adjusting of the flow rate and pressure in the pipelines have been inferred with the opening degree of adjusting valve as input and the parameter controlled as output.更多还原
