摘　　要：[Objective] The aim was to investigate the effects of sound wave on propagation of Chlorella pyrenoidosa to explore the optimal frequency for Chlorella pyrenoidosa.[Method] In the research,Chlorella pyrenoidosa was cultured for 7 d with sound waves at different frequencies and a control group was set to study effects of sound wave at different frequencies on growth of Chlorella pyrenoidosa.[Result] Growth of Chlorella pyrenoidosa was significantly improved by sound wave,especially for wave at 400 Hz.[Conclusion] Chlorella pyrenoidosa propagation would be promoted by sound wave at certain frequencies.[目的]研究声波对小球藻繁殖速度的影响,探寻适用于小球藻生长最佳频率。[方法]通过在不同频率的声波条件下对小球藻进行7d的培养试验,并设置空白对照组,研究不同频率的声波对小球藻生长繁殖的影响。[结果]声波对小球藻生长具有明显的促进作用,尤其是400Hz的声波作用效果最好。[结论]一定范围频率的声波可以有效促进小球藻的繁殖。
