对不可压缩粘性流体薄层中的受迫剪切流动进行了实验研究。利用条纹照片获得了主剪切流失稳后产生的旋涡流态的流函数。各种流动特性的确定和结果进行了比较，准二维流的稳定性理论。直接验证了准二维近似的适用性，并证明了从二次流流型重建驱动力的可能性。
Forced shear flows in a thin layer of an incompressible viscous fluid are studied experimentally. Streak photographs are used to obtain the stream function of vortical flow patterns arising after the primary shear flow loses stability. Various flow characteristics are determined and results are compared to the stability theory of quasi-two-dimensional flows. The applicability of the quasi-two-dimensional approximation is directly verified and the possibility of reconstruction of the driving force from the secondary flow pattern is demonstrated.
