声发射/声音信号的采集，频域、时域、功率谱等的分析.请配合NI9223使用。- Acoustic emission/capture sound signal, frequency domain analysis, time domain, power spectrum, etc. Please cooperate NI9223 use.

根据声发射传感器位置以及各传感器探测的时间（试验时间），计算定位出声发射源位置；适用二位坐标系。(According to the position of acoustic emission sensor and the detection time (test time) of each sensor, the position of acoustic emission source is calculated and located, which is applicable to the t
