The advance and the direction of research in auditory scene analysis (ASA), including psychological auditory scene analysis and computational auditory scene analysis (CASA), are reviewed. The psychological ASA uncovers the human auditory mental and intellectual perceptual procedure and principles of detection and separation of multi acoustic stream. The goal of CASA is to simulate the processing mechanism of human auditory system using computers that could extract desired information from noisy environment,...

The Zn-Al alloy matrix composites were prepared by high-intensity ultrasonic dilution of XD denoted in situ composites. The experiment showed that the tensile strength of the composites with particles of homogeneous distribution in the matrix was much higher than that of the matrix. The strengthening mechanism was attributed to Orowan theory. The evenly diluted strengthening phase of XD composites by high-intensity ultrasonic resulted from the cavitation in association with acoustic stream.

讨论并分析了600℃的SiCp/ZA27熔体中超声的作用机理和有效作用范围。研究结果表明:在实验所用超声处理条件下(20kHz,1kW),ZA27合金熔体中声空化效应引发的熔体局部高压最大可达105MPa,局部高温可达1.77×104K;声流在熔体体系各个部位的作用强度不同,要获得优质的复合材料就必须在工艺上保证熔体的各个部位均能受到超声的有效作用。高能超声之所以能够制备出颗粒均匀分布、界面结合良好的SiCp/ZA27复合材料是高能超声在金属熔体中产生的声空化与声流共同作用的结果。
