A little while after Dr Hawking worked all this out, Dr Unruh pointed out that if you have a body of fluid which contains a region that is flowing supersonically, sound waves would be trapped inside that region.

霍金博士解决所有疑问不久，Unruh博士指出：如果有一个容纳超音速流动区域的流体，那区域将会把声波收集在内。

A hydraulic resistance instrument composed by two pressure transducers was used to measure the hydraulic resistance across the two kinds of channels. The impedance on both channels was measured by a four electrodes impedance instrument with 5kHz constant current. A vibration generator was put on one set of the channel to produce about 50Hz sound waves. The signal was detected by a crystal pickup on the other set of the channel to examine the transmission of the wave along the two kinds of channels.

使用双压力传感器流阻仪对两种通道的流阻进行测定；使用5kHz恒流四电极方法对两种通道的阻抗进行测量；使用激振器在通道的一端产生一个约50Hz的振动，在通道另一端用晶体拾音器检测振动信号，对两种通道的声音传导特性进行了测定。
