本文报道了在1.4 ~ 2.3K温度范围内用椭偏法测量液态~ 4 He表面厚度的结果。垂直厚度t（其中密度从体积液体密度的90%变化到10%）随温度从1.4 K到2.1 K略微增加，在1.8 K时具有9.4 AA的平均值。有证据表明在2.1 K和λ点之间有2或3个AA的上升。
Ellipsometric measurements of the thickness of the surface of liquid 4He are reported for temperature from 1.4 to 2.3 K. The vertical thickness t within which the density changes from 90 to 10% of the bulk liquid density increases slightly with temperature from 1.4 to 2.1 K, having an average value of 9.4 AA at 1.8 K. There is some evidence of a rise of 2 or 3 AA between 2.1 K and the lambda -point.
