We present a mini-review of (some aspects of the) theory of so called chiral effects in hydrodynamic approximation. One considers fluids whose constituents are massless fermions. The underlying field theory incorporates quantum anomalies which are loop effects in gauge-field backgrounds not consistent with the chiral symmetry of the classical lagrangian. One of central theoretical claims is that the quantum anomalies trigger macroscopic fluid motions of calculable amplitude. An example is provided by the chiral vortical effect which is a helical motion of the fluid transporting the chiral charge along the axis of a vortex.

流体力学中量子异常的宏观表现（小型回顾）

我们对流体动力学近似中的手性效应理论（的某些方面）进行了简要回顾。人们认为其成分是无质量费米子的流体。潜在的场论结合了量子异常，量子异常是在规范场背景下的环路效应，与经典的拉格朗日手征对称性不一致。中心理论主张之一是，量子异常触发了可计算幅度的宏观流体运动。由手性旋涡效应提供了一个例子，该手性旋涡效应是沿旋涡的轴线传输手性电荷的流体的螺旋运动。
