结果表明，变量喷头的流量与射程平方和转速的乘积成正比。

The operating equation indicates that the discharge of the variable-rate sprinkler is proportional to the product of rotating speed and square spray range .

以方形喷洒域变量喷头为例，推导了方形喷洒域变量喷头射程随转角变化的理论方程，然后应用变量喷头工作方程推导了方形喷洒域变量喷头理论流量和转速方程。

To illustrate the application of the ( operating ) equation , the theoretical models of spray range , discharge and rotating speed of the variable-rate square wetted area sprinkler were derived .

研究表明：隙控式全射流喷头的流量大于试验用PY2摇臂式喷头8%左右，射程比摇臂式喷头的射程明显加大，最大增幅达到31%。

Results show that the flow rate of fluidic sprinkler is about 8 % more than that of impact sprinkler tested , while sprinkler pattern radius obviously increases , almost by 31 % .
