The influence of the size of sound lens and the sound velocity in sound lens material and crude oil and rock stratum on the sphere of action is studied.
分析了声透镜尺寸及材料中的声速、原油及岩层中的声速对其传播距离的影响。
As an imaging tool, the acoustic lens beats ultrasound imaging because the sound pulses can be focused much more tightly and can be easily repositioned.
作为一个成像工具,声透镜冲击了超声波的显像,因为声脉冲可以更加紧密地聚焦,可以很容易地重新定位。
When a sound wave strikes the spheres at one end of the acoustic lens, the sound gets converted into a type of shock wave known as a solitary wave.
当把声波打击在声透镜一端的球体上时,声波就会转换成称为孤波的某种类型的冲击波。
The wave front of the ultrasonic wave can be changed by using the sound lens.
利用声透镜的聚焦作用,可以改变超声波在岩层中的波阵面形状.
