摘要：

The flow around a source doublet in a two-dimensional shear flow along a flat plane is investigated analytically with an incompressible inviscid fluid. The velocity field is obtained by the linearized Euler equation. It is shown that the shear suppresses the three-dimensionality of the disturbance and makes the flow be rather two-dimensional one that parallel to the plane. A deformed vortex line consists of the looped line and the straight line of the shear flow.
