本文用经典流体力学方法研究了垂直直线涡附近的自由面轮廓。导出了数值解和近似解析表达式。对于纯~ 4 He,在T =0 K时,韧窝的深度为<$69.5 μ m,半深半径为<$4.26 × 104 μ m。3 He杂质的加入增加了中心深度。讨论了用相位对比技术检测涡线的可能性。
The free-surface profile near a perpendicular rectilinear vortex is studied with classical hydrodynamics. Numerical values and approximate analytic expressions are derived. For pure4He atT=0 K, the dimple has a depth ≈69.5Åand a radius ≈4.26×104Åat half depth. The addition of3He impurities increases the central depth. Possible detection of vortex lines with phasecontrast techniques is discussed.
