- acoustic beam deflector 声束偏转器
- 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）。

- His answer was right on the beam. 他的答案完全正确。
- It can also combine optical switching with the ATM(Asyn-chronous Transfer Model)switching when the speed of optical beam deflection reaches a level of nanosecond. So it can fulfil the demand for switching needed by high speed rate information network. 当光束偏转速度达到纳秒级时，该网络又可将光交换与ATM（异步转移模式）交换相结合，从而满足高速信息网络对交换的要求。
