中文摘要：

在水疗院运输管道的最商业的泥浆通常包含罐头更加降级的一些气体泵表演，而是煤气的内容的这小数量不能用常规方法在网上或不断地精确地被测量。在泥浆在压力波浪速度上基于气体的效果的分析，调查被执行验证方法的可行性用声音在泥浆决定煤气的内容速度。而且，它的实际测量方法也被讨论。越过管道的健全水平噪音光谱的非侵略的测量应该是泥浆气体内容的一个有希望的联机测量方法，这被发现。

英文摘要：

Most commercial slurries in hydrotransport pipelines usually contain some gas which can considerably degrade the pump performance, but this small amount of gas content can not be measured accurately online or continually using conventional methods. Based on analysis of effects of. gas on pressure wave speed in slurries, an investigation was carried out to validate the feasibility of the method to deter.. mine gas content in slurries using sound speed. Moreover, its practical measuring methods were also discussed. It was found that the non invasive measurement of the sound level noise spectrum across the pipeline should be a promising online measuring method of the slurry gas content.
