- In this paper, C language is made use of to calculate the concentration of the composite gases component according to opto acoustic effect and opto acoustic spectrum of gases.
- By analyzing the features of pipelines including wave-guiding and typical acoustic spectrum of manmade damages, a model composed of characters of acoustic wave was established.
- In order to find out slight leakage in boilers,to avoid disarranged stopping of boilers or stopping of boilers just after they started,a detecting technology and monitoring system with acoustic spectrum on boilers bearing pipe are developed.
- The survey covered a broad spectrum of topic.
- Acoustic Spectrum Analysis of Shale Mudding Degree
