摘要
本文较详细介绍了负压直读式盐田测修仪的工作原理、结构特点和使用方法等方面的情况,该仪器垠据“与水面联通的管道内负压一定时,管内液面高度与水面距离也为一定值”原理研制而成,具有操作方便、简单,测渗精度高等特点,有较大的经济开发价值。
The operational principles,structrural characteristics and usage of thesalt field negative pressure and direct-reading lysimeter are introduced in this paper.When the negative pressure in the tube connected to the water level is definite,the dis-tance between the level hight in the tube and the water level is also definite.Accordingto this principle,the lysimeter is developed.It is characterized by simple convenlent op-eration and high precision,and worthy to be developed economically.
