本文考虑了可压缩流体中的非均匀螺旋（Beltrami）流，给出了一类精确解。本文讨论了螺旋流的一个佯谬，并认为压缩性是解决这个佯谬的一个可能途径。给出了可压缩螺旋流的不同对称性的例子，特别是提出了ABC（Arnold-Beltrami-奇尔德里斯）流在可压缩螺旋流中的推广。John Wiley & Sons，Inc.
Helical (Beltrami) flow with nonuniform coefficient is considered for the case of compressible fluid and a class of exact solutions is proposed. A paradox of helical flow is discussed and the compressibility is considered as a possible resolution of the paradox. Examples with different symmetries are given for the compressible helical flow and, in particular, the generalization of the ABC (Arnold-Beltrami-Childress) flow for the compressible case is proposed. ©1995 John Wiley & Sons, Inc.
