1
指出对质量流量影响最大因素依次为蒸气密度、可膨胀系数、节流件内径及流量系数。
Also the paper lists the factors mostly affecting the mass flow measurement consecutively as steam density, expandable coefficient, inner diameter and flow coefficient of the throttle element.
2
当原料气流过节流件时，产生焦耳-汤姆逊膨胀及降温，使部分气体和大部分水蒸汽液化。
As the feed stream flows through the choke, the resulting J-T expansion and cooling causes some gas and most of the water vapor to liquefy.
3
如果井口压力超过管道所需的压力，则可使气体通过节流件，以等焓焦耳-汤姆逊膨胀获取冷量。
If the wellhead pressure exceeds that of the pipeline, then the gas can be passed through a choke or throttled in a constant-enthalpy Joule-Thomson expansion to provide cooling.
