Experiment on acoustic pyrometry is done using the chirp signal, white noise and sine wave respectively in a 300MW boiler in one domestic power plant, through fire hole on furnace wall.
在国内某电厂的300MW机组锅炉上，利用炉墙上的观火孔，分别用扫频信号、白噪声信号和正弦信号进行了冷态下的声学测温试验。
Increasing the amount of overlap can be done by selecting, for the point relative to the drivers through which reference line 36 passes, a point close to, or even on, the acoustic drivers.
通过选择接近于声学驱动器的或甚至在声学驱动器上的点作为基准线36所经过的与声学驱动器有关的点，可以增加重叠量。
Flow mapping analysis can also be done with the data to create a map of the acoustic activity and present it in a 2d image that will show the flow path in the well.
利用数据可实现流动成像分析，生成声音活动的图像，并将其展示在能够显示井下流径的2d影像中。
