mass flow characteristic的用法和樣例：
例句
- Flow curve tending to straight line.excellent regulation performance.
流量特性趨于直線(xiàn)，調節性能好。 - Throttling is not recommended because partially open gate valves exhibit flow characteristics not conducive to accurate and consistent flow control.
不建議用于節流應用，因為部分開(kāi)啟的閘閥所表現的流量特性并不利于精確和一致的流量控制。
