摘要
基于超声光栅研制了测量液体浓度和声速的实验装置,该装置避开了测量超声光栅与光屏之间的距离,并使用CCD相机拍摄图像测量条纹间距.利用Python开发了集数据计算、数据拟合、数据输出为一体的配套软件,以实现实验结果的快速输出.本装置制作简单,成本较低,容易操作,此外其原理简单易于理解,数据处理结果还可以进行数字化显示.利用该装置还可以研究温度对声速的影响规律.
This paper developed a solution concentration and sound velocity measurement device based on the ultrasonic grating.The device avoided measuring the distance between the ultrasonic grating and the light screen,and used a CCD camera to capture images and measure the stripe spacing.A set of supporting software integrating data calculation,data fitting,and data output was developed using Python to achieve rapid output of experimental results.This device was simple to manufacture,low in cost,easy to operate,and its principle was easily understood.The data processing results could also be digitally displayed.This device could also be used to study the effect of temperature on sound velocity.
