说明：  按照通常的应用顺序，处理地震数据包括三个主要步骤-去卷积，叠加和偏移。表示处理坐标（中点，偏移和时间）中的地震数据量。去卷积沿时间轴起作用。它从记录的地震迹线中删除了基本地震子波（通过地球和记录系统的各种作用修改的源时间函数），从而提高了时间分辨率。去卷积通过压缩小波来实现此目标。堆叠也是压缩的过程（速度分析和静校正（）。特别是，首先通过对每个CMP道集的迹线应用常规偏移校正（速度分析和静态校正），将数据量减少到零偏移的中点时间平面（棱镜的正面）。 ，然后沿偏移轴求和。结果是一个堆叠的部分。(Generally, seismic data processing includes three steps: deconvolution and migration. Represents the amount of seismic data in processing coordinates (midpoint, offset, and time). Deconvolution works along the time axis. It removes the basic seismic wavelet (the source time function modified by various actions of the earth and the recording system) from the recorded seismic traces, thus improving the time resolution. Deconvolution achieves this goal by compressing wavelet. Stacking is also a process of compression (velocity analysis and statics). In particular, by applying conventional offset correction (velocity analysis and static correction) to the trace of each CMP gather, the amount of data is reduced to the midpoint time plane of zero offset (the front of the prism). And then sum along the offset axis.)

风机叶片的裂纹和断裂是导致风机机组事故的重要因素之一，尽早诊断出风机叶片的 故障部位与故障程度，对安全生产具有意义重大。本文将叶片振动信号作为研究对象，利用小波分解方法对其进行信号分解，并与时域和频域方法处理结果进行对比分析，得出诊断结论。仿真结果表明: 小波分解方法可以更有效的获取故障特征信号，具有较高的故障诊断率。(The crack and fracture of fan blade is one of the important factors that cause the accident of fan set. It is important for safety production to diagnose the fault location and failure degree of fan blade as soon as possible. In this paper, the vibration signal of the blade is taken as the object of study. The signal is decomposed by the wavelet decomposition method, and the results are compared with the time domain and frequency domain methods. The diagnosis conclusion is obtained. The simulation results show that the wavelet decomposition method can acquire the fault characteristic signal more effectively, and has higher fault diagnosis rate.)
