It is shown that the sea surface topography not only has a response to the wind field quite well but also can better reflect the propagation of warm water mass . Therefore the sea level is a effective indicator for monitoring ENSO event .

证明海水 水位不但对风场有很好的响应，而且还能较好地反映暖 水团的移动，是监视ENSO事件的一种有效 指标。

Drum water level of boiler is an important indicator for safe and reliable operation of industrial boiler .

汽包 水位是工业锅炉安全、稳定运行的重要 指标，是自动控制的重要环节。
