摘　　要：为了研究声共振的条件,在风洞中对三种顺排、四种错排的密排管束进行了试验。还在管束中装入三种防止嗓声的隔板,取得了显著的效果。Three in-line and four staggered arrays of closely spaced tubes have been tested in a wind tunnel, to investigate the conditions under which acoustical resonances do or do not materialize.Three types of detuning baffles have been inserted into the tube bank for prevention from acoustic vibration. The noise can be reduced remarkably.
