摘要
该文介绍了一种基于声学自校正原理的新型雨量计。声学自校正原理能消除声速的不确定性所带来的影响,实现雨量的精确测量。新型的雨量计不仅克服了雨强大小对测量的影响,而且提高了测量精度。理论分析与大量的实验数据证明,这是一种高精度的具有实用价值的雨量计。
A novel rain gauge based on acoustic self-calibration principle was proposed in the paper.Acoustic self- calibration principle can eliminate the uncertainty of the velocity of ultrasound and achieve accurate measurement of rainfall.The rain gauge not only overcomes the influence on the rainfall measurement under intensive rainfall condi- tions ,but also improves the precision of rain gauge.Both theoretical analysis and large number of experimental results show the effectiveness of the rain gauge.
