Through dividing electronic expansion valve from evaporator system and based on constant gain of superheat open looprule, the compensation theory of valve head was analyzed.
通过将电子膨胀阀与受控对象(蒸发器)细化分开来,并依据恒定开环增益准则从理论上分析了阀头补偿原理。

If you don't want the active rule to be reevaluated, you should include the rule's optional no-loop attribute and give it a value of true.
如果不希望这种情况发生,则应该包括rule的可选no - loop属性并将其赋值为true。
