标题： Linear instability of plane Couette and Poiseuille flows

摘要： 结果表明，即使在有限的雷诺数下，平面Couette流的线性不稳定性也会发生，这与已知的实验数据相符。 这一水动力学稳定性线性理论的新结果仅仅由于放弃了扰动在流动方向上传统的纵向周期性假设而获得。 显示英文摘要

摘要： It is shown that linear instability of plane Couette flow can take place even at finite Reynolds numbers which meets with known experimental data. This new result of the linear theory of hydrodynamic stability is obtained only due by abandoning traditional assumption of the longitudinal periodicity of disturbances in the flow direction.
