混凝土检测中的正弦波正演模拟计算；损伤分析与完好分析对比；-Concrete Inspection of the forward simulation sine wave damage analysis and integrity analysis and comparison

混凝土损伤诊断信号处理，用HHT变换，得出不同损伤程度下采集到信号的差距-Concrete damage detection signal processing, with HHT transform, it is concluded that the collected signals under different damage degree of the gap
