结果表明，在无奇异性的情况下，超流体He-3的A相速度场的旋度完全由序参数对称轴的空间梯度L-→→决定.作为这一关系的一个简单应用，本文论证了在体积V中柱对称织构中，液体应具有ρ、S、V、ℏ、M等阶的非零热平衡轨道角动量。
It is shown that the curl of the velocity field generally identified with v→ s in the A phase of superfluid He 3 is entirely determined in the absence of singularities by the spatial gradients of the order-parameter symmetry axis l→. As a simple application of this relation it is argued that in a texture of cylindrical symmetry in a volume V, the liquid should have a nonvanishing thermal-equilibrium orbital angular momentum of order ρ s V ℏ M.
