在油、气工业中，蒸汽压是现场工程师需要了解的烃类的最重要的物理性质之一。文中介绍了一种新的方程，它只用一组广义参数就能精确地预测烃类蒸汽压。对这个用于预测94种不同流体的1106个蒸汽压数据点的广义方程的精度进行了检验。
In the oil and gas industry, vapor pressure is one of the most important physical properties of hydrocarbons that field engineers need to understand. In this paper, we introduce a new equation that accurately predicts hydrocarbon vapor pressures using only a single set of generalized parameters. The accuracy of this generalized equation for predicting 1106 vapor pressure data points for 94 different fluids was tested.
