摘　　要：在流体力学托里拆利定律的实验中,利用数码相机拍摄容器内液面和从出口流出的流体轨迹的图像,并采用数字图像处理和数值计算相结合的方式,测量液面高度差和相应的出口处流速,对托里拆利定律进行验证。该方法装置简单,易于实现,并具有较好的精确性。In the experiment of Torricelli’s law in fluid mechanics,a digital camera was used to take images of the surface of the fluid in the container and the flow trajectory from the orifice,and a combination of digital image processing and numerical calculation was used to measure the height of fluid above the orifice and the corresponding speed of fluid flowing from the opening,to verify the Torricelli’s law.The method is simple in device,easy to implement,and has good accuracy.
