Abstract
The surface tension of liquid nitrogen at 77 K is measured to be 9.053 dyn/cm in terms of the double capillary method,which may be reasonable in comparison with the single capillary method.The nonlinear equation *=*0(1-T/TC)n has been used to describe the relation between the surface tension with the temperature for liquefied N2,O2,Ar,Xe,H2,Ne,He,F2,D2 and Kr.The parameters *0 and n of the liquefied gases above are fitted by the linear regression method with higher accuracy than that in the literatures.
