临界区内气液相在重力场中密度方程的化简

SIMPLIFICATION OF THE GRAVITY-INDUCED DENSITY PROFILE EQUATIONS FOR VAPOR AND LIQUID CLOSE TO THE CRITICAL POINT

从一些合理的假设出发，对ｖａｎＬｅｅｕｗｅｎ和Ｓｅｎｇｅｒｓ提出的二大微分方程进行了化简．新方程的解析解与原方程的数值解吻合良好．

The second-order differential equations proposed by van Leeuwen and Sengers have been simplified based on some rational assumptions. The explicit relations obtained are in good agreement with the numerical solution of the differential equations.
