本文提出了一种新型的测量液滴特性的微波传感器，建立了分析理论，并制作了工作样机。基于微波传感器的理论分析与实验结果吻合较好。通过优化设计，实现了良好的线性度，蒸馏水滴体积测量精度约为0.5 µl，该微波传感器已用于同时测量物理化学和微波化学领域中的关键参数--液滴的表面张力、物种浓度和微波吸收特性。
A novel microwave sensor for measuring the properties of a liquid drop has been invented, its analytical theory established and a working prototype has been constructed and tested. It was also found that the theory based on the microwave sensor is in good agreement with the experimental results. Excellent linearity is achieved by optimizing the design, with an accuracy of distilled water drop volume measurement of approximately 0.5 µl, and this microwave sensor has been used to measure surface tension, species concentration and the microwave absorption properties of a liquid drop simultaneously, which are the key parameters in the fields of physical chemistry and microwave chemistry.
