| Abstract: | 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. |
