摘要
目的:开发了一套测量声输出参数的系统,为进一步研制适用于军事计量巡检工作的便携式仪器奠定基础。方法:采用水听器作为换能器,采集超声信号在空间声场焦平面上一点的声压波形。通过对声压波形的参数进行数值运算,得到所关心的超声声输出参数。结果:能够在误差允许的范围内测量出主要的声输出参数。结论:该方法切实可行,得到的数据可重复性好。
Objective： In order to suit the need of military itinerant inspection, an acoustic output measurement system, which is the basement for the manufacture of a portable instrument, is dcvclopped. Method： A hydrophonc is used as energy converting equipment to collect waves of acoustic pressure in the field of ultrasonic. Though some calculations, a series of acoustic output parameters are achieved. Results： The main acoustic output parameters can be measured in the range of permitted errors. Conclusions： This method is feasible and data can be well repeated.
