摘　　要：用群论方法求出了平板边界层、二维射流、涡丝扩散3种情况下粘性流动的相似性解,回避了一般教科书中求解该问题时所使用的大量的物理推理和逻辑试探,从而使求解过程显得简单明了.Based on group theory, similarity solutions to viscous flows of plate boundary layer, twodimensional jet and vortex filament proliferation are obtained. And many physical reasonings and logical probes used in general textbooks to solve this problem are evaded. So its solving process is much simpler and clearer.

关 键 词：粘性流动 相似性解 平板边界层 二维射流 涡丝扩散
