| 摘 要： | 恒压喷灌系统调压罐空气状态变化多变指数是系统设计的重要参数。首先分析了多变指数对调压罐容积的影响，并通过试验得出正常运行情况下压力变化过程及环境温度、调压罐容积对多变指数影响较小，多变指数实测平均值为ｎ＝１．０４２。

| Abstract: | The statement index of air chamber is an important parameter for the design of a constant pressure sprinkle irrigation system. In this paper, effects of the statement index on design volume of an air chamber are analyzed theoretically. Experimental results show that pressure changes, ambient temperature and volume have little effects on statement index of an chamber operating normally. Average value of the statement indexes measured in this experiment is 1.042. |
