摘要
推导了声速测定实验中合成声场的位移波动方程、声压波动方程以及两者之间的关系.进一步剖析合成声场的性质并用微机进行模拟,以获得对合成声场更加客观的认识.
The equation of displacement wave and sound pressure wave in the sound velocity experiment are derived. And their relation is analyzed. To obtain more objective recognition, the synthesis sound field is analyzed further and is simulated with computer.
