Both his mother and his wife were deaf, hence his interest in acoustics. Others had created working phones, but Bell gave us the first commercially practical telephone, as well as the metal detector and the graphophone, an improved version of the phonograph.

亚历山大-格雷厄姆-贝尔的母亲和妻子都是聋子，所以，他对声学很感兴趣，其他人研制了工作电话，而贝尔为我们送出第一个商业实用电话，和金属探测器以及改良版留声机——格拉福风留声机。

Acoustic Doppler Current Profilers is a new kind of flow measuring device widely used in hydrometry. It uses the principle of Acoustic Doppler instruments to measure flow velocity profile. A short time flow measurement, high resolution, good accuracy, integrity data and great information are the characters of ADCP.

多普勒测流仪是当前在水文行业推广的一种新型测流仪器，该仪器利用声学多普勒原理，测量水流速度剖面，具有测验时间短、分辨率高、精度好、资料完整、信息量大等优点。
