近年来超声波在工业上得到日益广泛的应用,但其对人体的生物学作用尚研究得不多。作者谈到以往的许多研究材料,说明了超声波对人和动物机体的有害作用。作者研究了超声波在技术应用中对人体的作用。研究了使用超声波清洗另件、打鑽和焊接的工人。工人直接接近超声波设备或在离其一米之处。工作場所空气中超声波和可听声对工人的作用具有很大卫生学意义。在发生器以及在技术设备中都有各种频
In recent years, ultrasound has been widely used in industry, but its biological effects on the human body are still not much studied. The authors talked about many of the previous research materials that illustrate the harmful effects of ultrasound on humans and animals. The author studied the effect of ultrasound on the human body in technical applications. Studied the use of ultrasonic cleaning other pieces, drilling and welding workers. Workers approach the ultrasound device directly or at a distance of one meter. The role of workers in the air and audible sound in the workplace is of great hygienic significance. There are various frequencies in the generator and in the technical equipment
