One of this method is to produce an acoustic beam with a controlled direction. 用相控声源的主要目的之一是产生一个可以控制其方向的声束.
The experimental results showed that along with increasing the delay-tirne of impulsive signal on adjacent array elements,the steered radiation angle of acoustic beam of phased-array becomes larger and larger. 实验结果表明,随着相邻阵元的激励信号延迟时间的增加,相控线阵的辐射声束指向角不断变大;
When an acoustic beam, limited both in time and space, radiated from liquid to a plane lipuid solid interface, we observed the nonspecular reflection phenomena (the reflected beam has a fixed reflected angle in some range of incident angle). 当时间·空间上有限的声束入射到液固平界时，我们观察到非镜面反射现象（即在一定入射角范围内有一个以固定角反射的反射波）。
