摘要：

Variations of acoustic emission signals of leakage of the heater versus inner pressure, leakage aperture, transmission distance and liquid state in the outer pipeline were studied through experiment and analysis. By changing one of the four factors each time, leakage failure reasons were concluded. Research results would be applied into leakage detection of heater. © 2015 SERSC.
