摘要
该文讨论了超声波声速测量实验中出现的几个问题,并通过数值计算,说明了 超声波能量随距离的增大而形成的衰减趋势,并对影响测量精度的因素进行了讨论。
This paper discusses some problems in supersonic velocity measurement, and expounds, in the form of numerical computation, the availability results about supersonic energy attenuation adapting to distance, as well as the influential factors on the measurement.
