The data required in the method are: liquid density, Z_(RA)and vaporization enthalpy at normalboilingpoint.
本方法所需数据为：液体密度、Z_（RA）值及正常沸点下蒸发焓。

The normalboilingpoint of a liquid is the special case at which the vapor pressure of the liquid equals the ambient atmospheric pressure.
常压沸点是一个特例，其中，液体的蒸汽压与环境大气压相等。

It is found that the parameter is directly proportional to the molar volume of liquid at the normalboilingpoint, and its values have the additivity of groups.
