摘　　要： 改进了SW-1型声速测定仪,研究了两换能器互成角度时的声速测量,说明声源发出的不是平面波,但在某一固定方向上可以看作是近似于平面波的声波. Having improved the SW-1 type of sound velocity detector, having conducted research on the sound velocity measuring when the two transducer into each other at the point, the conclusion is reached that the sonic which the sound source sends out is not a plane wave, but in a fixed direction, it can be seen as similar to the plane wave.

关 键 词： 声速测量 换能器夹角 线性拟合 平面波
