针对混合流体对流增压过程中的密度变化情况，从液体的压缩性及膨胀性理论出发，分析了液体在不同状态时的物质特性；将混合流体增压过程分成2种不同状态的混合和增压部分，同时结合质量守恒定律，分别对2个过程的密度特性进行了分析，并推出了2个过程的密度数学模型；采用Matlab软件对2个过程的密度特性曲线进行了绘制。所绘制的密度曲线表明：一定温度下，在增压过程中，流体的密度随着压强的增大而增大；一定压强下，随着温度的升高，流体的密度随之降低。

According to the change of the liquid density of the mixed fluid,from the liquid compressi-bility and expansion theory,the characteristics of liquid in the state of different material are analyzed, and the mixed fluid pressurization process is divided into two different state of mixing and pressuriza-tion two parts.At the same time,combining with the conservation of mass,respectively,the density of the process of two features are analyzed,and two density mathematical models of the process are in-troduced.The curve drawing of density within two process characteristic are drawn by using Matlab software.The drawing density curve shows that the density of the fluid increases with the increase of the pressure under a certain temperature,and the density curve decreases under a certain pressure with the increase of temperature.
