超声波今天已在各个方面被广泛地应用着,而且继续在扩大其应用范围。在这些应用中,很大一部分是与本文所讨论的几个性质有关的。但是由于作者水平的限制,只作一般介绍性的討論,并用它说明一些应用。一、超声波在粒子間传播时产生的引力与斥力(指流体介質) 超声波本来是声波的一种,它在流体中以纵波的形式传播,引起介貭分子在平衡位置来回振动,这种振
Ultrasound has today been widely used in all aspects, and continues to expand its range of applications. A large part of these applications are related to several of the properties discussed in this article. However, due to the limitations of authorship, only general introductory discussions have been made and use it to illustrate some of the applications. First, the ultrasonic propagation in the particles generated when the gravitational and repulsion (referring to the fluid medium) Ultrasonic was originally a sound wave, it is in the form of longitudinal waves in the fluid transmission, causing meson molecules back and forth in equilibrium position vibration, the vibration
