摘要
该文采用多次拟合的方法建立了一组可用于计算超流氦－４热物性的计算关联式，可以很方便地计算出在Ｔ＝１０～Ｔλ和Ｐ＝０～１．０ＭＰａ范围内的多种热物理性质．数据可靠、使用方便．所采用的多次拟合法同样可推广应用于确定其它介质性质在双参数控制下的计算关联式．
The themodynamic and themophysic properties are required in the research of superfluid helium,but they are supplied nearly all in the type of data and figures,which could not be directly used by computer in work such as CAD,calculation and so on.A multi-fitting method is recommended to build correlations from two parameter adta source(T,P) for calculating the properties f superfluid helium in the range of T-1.0～Tλand P=0～1.0 MPa.Teh corrdlations are reliable and simple in use.The multifitting method can also be used to set up any other properties of other media with two control parameters.
