摘要
对用力敏传感器测量液体表面张力系数仪器进行研究,利用连通器和浮力原理对原仪器的升降装置进行了改进,提高了仪器的稳定性和重复性。同时将待测液体和吊环封装在玻璃容器中,消除了空气的流通对实验的影响,减少了实验误差。
The liquid surface tension coefficient measurement facility by abruption was studied. The lifting motion was improved by connecting vessel and buoyancy principle. The stability and repeatability of the facility was en- hanced. The measuring liquid and hanging ring were sealed in a glass container, which dispels the effect from the air circulation and the experimental error was reduced.
