即調節閥的放大系數是變化的，它隨相對流量的增大而增大。優先選用等百分比特性閥的場合為：實際可調范圍大；開度變化，閥上差壓變化相對較大；管道系統壓力損失大；工藝系統負荷大幅度波動；調節閥經常在小開度下運行。除了以上兩種常用的流量特性之外，[2]還有拋物線特性和快開特性等其他流量特性的調節閥，理想的流量特性曲線如圖1所示。在密封結構上，若流量特性精度要求高，則可選用高精度流量特性的金屬密封型，而軟密封型精度較低。節閥壓降的系統考慮調節閥作為過程控制系統中的終端部件，是常用的一種執行器。按過程控制系統的要求，調節閥應具有在低能量消耗的狀態下工作，且能充分與系統匹配的工作特性。但是在調節閥的使用中這兩個要求是不能同時滿足的，甚至是互相矛盾的。在要得到同樣的流量Qmax的情況下，選擇一只較的調節閥，雖然其他阻力不變而總的阻力必然比較大，形成大的系統總壓降。假若物流的推動力是由泵產生，就意味著必須選功率大一些的泵和電機，這樣必然帶來大的能耗。

“因為價差客觀存在，所以澳方的訴求也有其合理成分。”周希增接受本報記者采訪時表示。聶秀欣則表示了不同的意見，“中方頑強堅持的意義不僅僅在價格和成本，而且在于規則”。她告訴本報記者，27年澳礦的離岸價格是51美元/噸，如果按照當前通行的65%的漲幅漲價，今年離岸價格應為84.15美元/噸，若按澳方堅持的85%提價則為94.34美元/噸，所以價差為1美元/噸。“1美元的價差并不是很大，但澳方的行為破壞了1981年以來形成的鐵礦石談判規則。
