本文讨论了分离两种相对运动流体的平面无限大涡面附近的线性Kelvin-Helmholtz不稳定性。计算概括了现有的治疗，包括相对论相对运动和相对论内部声速。不稳定模式的特征在两个极限中被概述（a）当声速比大时，和（B）当声速比等于1时。这些结果的相关性束模型河外射电源进行了简要讨论。
A discussion of the linearized Kelvin-Helmholtz instability in the vicinity of a plane infinite vortex sheet separating two fluids in relative motion is presented. The calculation generalizes existing treatments to include relativistic relative motion and relativistic internal sound speeds. The character of the unstable modes is outlined in the two limits (a) when the sound speed ratio is large, and (b) when it is equal to unity. The relevance of these results to beam models of extragalactic radio sources is briefly discussed.
