The liquid in the pipeline under certain conditions and partially vaporizes into gas state, bubble, formation of gas-liquid two-phase flow which is the process of flash.
管道中的液体在一定的条件下，部分液体气化成气体状态，产生气泡，形成气液两相流这就是闪蒸过程。
Two-phase flow widely exists in processes such as power, chemical, petrol, metallurgy, pipeline transport, medical and refrigeration industries.
两相流广泛存在于动力、化工、石油、冶金、管道运输、医药、制冷等领域。
Therefore, it plays an very important role to study two-phase flow in the pipeline and its safety.
因此及时研究两相流管道的积液情况及其安全性，具有非常重要的作用。
Studied two conditions of acoustic signals when it was single-phase gas and two-phase flow in the pipeline from sound spectrum, acoustic energy, peak frequency and amplitude.
分别从声波频谱，声波能量，峰值频率，以及幅值等方面对管道内为单相气体和两相流体两种状态下的声波信号进行了研究。
The paper used acoustic detection method; tested the horizontal pipeline and undulating pipeline in single-phase and two-phase flow situations, and gained the corresponding acoustic signals.
本文采用声学检测的方法，对水平管和起伏管在单相气体和两相流体的情况分别进行了测试，得到了相应的声波信号。
The wet natural gas in transmission pipeline assumes two phase of gas and liquid, so its flowing always assumes a slow transient flow state.
在实际运行中，湿天然气在输送管道中存在气液两相，因此管道中的流动总是处于慢瞬变流动状态。
The wet natural gas in transmission pipeline assumes two phase of gas and liquid, so its flowing always assumes a slow transient flow state.
在实际运行中，湿天然气在输送管道中存在气液两相，因此管道中的流动总是处于慢瞬变流动状态。
