sonic signal meaning in Chinese

音频信号

It testifies that chaos is existed in the sonic signal of boiler tube leak , according to the chaos theory and the correlative contents about the sky dynamics , and illustrates the physical meanings of the lyapunov exponent ( the change at the place of the boiler tube leak ) , based on the calculational methods of the lyapunov exponent and the peculiarities of boiler tube leak detection and diagnosis
根据混沌理论与空气动力学的有关理论，确定了炉管泄漏声信号中存在着混沌，在讨论如lyapunov指数的算法的基础上，针对锅炉炉管泄漏检测与诊断的特点，明确了lyapunov指数的实际物理含义(炉管泄漏点处状态的变化) 。
Because temperature and wind greatly influence the spread of sound in the air , they produce interesting effects similar to the optical phenomenon of mirage . through analysis of the sonic signal , we can therefore estimate the atmospheric conditions such as the temperature and or the wind distribution aloft
由于风和温度都对声音的传播速度有很大影响，也会产生类似光学上的海市蜃楼那样的现象，因此，透过分析声音讯号，亦可估算当时大气的性质如温度的高低或风力的分布。
