超声波技术的研究从十九世纪末开始,已有几十年发展历史。目前,在国内外已普遍应用于工农业生产、军事、科学研究、医疗卫生及生活服务等各个领域,其应用范围非常广泛,效益显著。为了应用超声波技术解决江河、湖泊、水库的水文要素测量,近几年来,我国有关科研院所、工厂、大专院校及水文部门进行了大量试验研究,研制出一批船用回声测深仪、水文缆道超声波测深仪、超声波流速仪和超声波水位计等,在一部分水文站的测深、测速和水位观测中应用,
The study of ultrasonic technology has been developing for several decades since the end of the nineteenth century. At present, it has been widely used in various fields such as industrial and agricultural production, military, scientific research, medical and health care and living services at home and abroad, and has wide range of applications and significant benefits. In order to apply ultrasonic technology to solve the hydrological factor measurement of rivers, lakes and reservoirs, a large number of experimental studies have been carried out by relevant research institutes, factories, universities and hydrological departments in China in recent years, and a batch of marine echo sounder, hydrology Cable channel ultrasonic sounder, ultrasonic flowmeter and ultrasonic water level gauge, etc, which are used in the depth measurement, velocity measurement and water level observation of some hydrological stations,
