| Abstract: | Due to the advantage of new structure about, the annoyance problems were solved in the experiment on measuring saturated vapor pressure of pure liquid. These problems were such as the difficulty in injecting sample and washing, the backward flow of gas, the impurity of liquid vapor, etc. When the new type isopiestic pressure gauge is used, operator can finish his measurement work with one time injection of sample. The application of new type isopiestic pressure gauge implied facilitates of manipulation, enhancement of efficiency and accuracy of data. |
