摘　　要：利用PASCO物理平台实验附件可组装性强的特征,设计与搭建了超声光栅实验装置,获得了清晰、直观的超声光栅衍射光强分布图,并利用极值查找等数据处理工具确定精确的衍射条纹位置.在此基础上,通过测量与计算得到了不同酒精溶液浓度下的超声波声速.Based on the PASCO physics experiment platform,an ultrasonic grating experiment device was designed.This device could obtain clear and intuitive light intensity distribution.The precise location of the diffraction stripes were confirmed using relevant data processing tools.Therefore,the supersonic velocity of different concentrations of alcohol solution was calculated.
