超声波的特点
超声波的特点
Characteristics of ultrasound
1、超声波在传播时,方向性强,能量易于集中。
1. When ultrasonic wave propagates, it has strong directivity and easy to concentrate energy.
2、超声波能在各种不同媒质中传播,且可传播足够远的距离。
2. Ultrasonic wave can travel in various media and can travel far enough.
3、超声与传声媒质的相互作用适中,易于携带有关传声媒质状态的信息(诊断或对传声媒质产生效应。(治疗)
3. The interaction between ultrasound and the medium is moderate, and it is easy to carry information about the state of the medium (diagnosis or effect on the medium). (treatment)
超声波是一种波动形式,它可以作为探测与负载信息的载体或媒介(如B超等用作诊断);超声波同时又是一种能量形式,当其强度超过一定值时,它就可以通过与传播超声波的媒质的相互作用,去影响,改变以致破坏后者的状态,性质及结构(用作治疗)。
Ultrasonic wave is a form of wave, which can be used as a carrier or medium for detecting and loading information (such as B-ultrasound, etc.) and it is also a form of energy. When its intensity exceeds a certain value, it can affect and change the state, nature and structure of the latter through the interaction with the medium that transmits the ultrasonic wave (for treatment).
