【摘要】 对声速测定(超声)实验中接收换能器在入射波和反射波激励下,换能器的响应信号进行了分析.推导出了叠加信号的表达式,指出该信号为一振幅随位置周期性变化的简谐波,两相邻极值振幅时接收换能器相应位置差为半波长.更多还原

【Abstract】 The responding signal of the receiving transducer under inspiring by the input supersonic and its reflection wave in experiment of sound velocity measurement is analyzed.According to the equation of superposition signal derived by us,it shows that the superposition signal is a simple harmonic wave,and the transducer removes half wavelength when the amplitude changes to maximum consecutively.更多还原
