经过较长时间的筹备,《声学与电子工程》现在出版了。 声学有悠久的历史。在19世纪经典声学理论就已成熟。后来,电子学的出现带来了发射、接收、放大、处理和显示声信号的先进手段,声学的面貌焕然一新。大到海洋、大气、地壳中的探测、通信,小到物体内部结构、缺陷的探测,甚至晶格范围内的微结构的探测,都可以用声学方法完成。声学与电子工程不但在国防和国民经济中起着重要作用,而且在人民生活中的作用也愈来愈大,如广播、扩音、噪声控制、超声诊断与治疗等日益成为人们生活不可缺少的伴侣。
After a long period of preparation, “Acoustics and Electrical Engineering” is now published. Acoustics has a long history. In the 19th century classical acoustic theory has matured. Later, the advent of electronics brought advanced methods of transmitting, receiving, amplifying, processing and displaying acoustic signals that acoustically refreshed. Large to the ocean, the atmosphere, the detection of the earth’s crust, communications, small objects to the internal structure, detection of defects, and even the detection of microstructure within the lattice range, can be done by acoustic method. Acoustics and electronic engineering not only play an important role in national defense and national economy, but also play an increasingly important role in people’s life. Radio and sound amplification, noise control, ultrasonic diagnosis and treatment are increasingly indispensable to people’s lives companion.
