| 摘 要： | 利用双毛细管法测定了液氮沸点温度下液氮的表面张力。用非线性方程γ=γ0(1-T/TC)n描述了液态N2、O2、Ar、Xe、H2、Ne、He、F2和Kr的表面张力与温度的关系，并采用一元线性回归的方法拟合了上述各流体的参数γ0和n,准确度高于文献值，说明方程能正确表达表面张力与温度的关系。这些数据有利于对上述低沸点气体进行准确的热力学计算。

| 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. |
