The structure of a single cylinder has been investigated in detail by many authors. But little is known about the wake structure of a group of cylinders in complicated configurations. This paper presents the first step to this complicated problem. We made a measurement by hot-wire anemometer in a small low-turbulence wind tunnel. The most important process in the wake is the randomization process in the vortex street. We introduced the objective measurement of the wake by comparing line and continuous spectra. It was proved that the downstream cylinder screens the vortex street of the upstream cylinder.
