摘要
利用霍尔测速器改造落球法测液体粘滞系数传统实验装置,可实现升球法与落球法随意切换测液体粘滞系数,可测量透明液体与不透明液体粘滞系数,这是传统粘度系数测量实验装置无可比拟的。该实验装置不仅有效克服了传统粘度系数测量实验存在的诸多问题,提高实验测量精确度,拓宽了实验测量范围,而且有助于实践创新人才的培养,加快新工科建设。
The traditional experiment device of measuring liquid viscosity coefficient by falling ball method is improved by Hall speedtrap device in this article.The reformed viscosity coefficient measuring device can realize accurate measurement for various liquid viscosity coefficient by rising ball method and falling ball method,including transparent liquid and opaque liquid.Compared with the traditional measuring device,the improved device not only improves the accuracy of experimental result,broadening the range for measurement,but also contributes to the cultivation of innovative and practical talents,speeding up the construction of new engineering disciplines.
