By measuring the cooling curve and quench severity of quenching oil at various flow rates, the relationship among the hardening capacity, quench severity and flow rate was established.

对淬火油在不同流速下的冷却曲线和淬火烈度进行了测量，建立了硬化能力、淬火烈度与介质流速三者之间的关系。

With the suction superheat kept constant meantime, the valve opening, refrigerant mass flow rates and the cooling capacity between two individual units exhibit a parabola relationship.

若同时保持吸气过热度一定，则三联式系统内两单机的膨胀阀开度、制冷剂质流量、制冷量呈现出抛物线的依变关系；
