摘　　要：声速除了可利用共振干涉法和相位比较法测量外,还可以用干涉、衍射及“洛埃镜”反射等方法测量．声速实验的改进,不仅可扩展声速测量的方法,而且也可加深学生对波动学规律和本质的理解．The speed of sound wave is measured utilizing sympathetic vibration interference, phase comparison, ultrasonic interference and diffraction, reflection of Lloyd＇s mirror. These improvements are supposed to expand the measurement method and deepen the understanding of the laws of waves.

关 键 词：声速 相位 洛埃镜 反射 干涉 衍射
