根据阻抗匹配的特点，提出了一种简单易行的Ｔ型匹配网络，并从理论上给出了网络中所需各电感电容的计算公式，通过实际对几个换能器的匹配，发现实验结果与理论基本符合 According to the characteristics of impedance matching, a simple and easy T-matching network is proposed, and the calculation formulas of the required inductance and capacitance in the network are given theoretically. Through the actual matching of several transducers, it is found that the experiment The result is basically in line with the theory
