基于传输线理论，采用三支节液态调配器以达到托卡马克离子回旋共振加热（ICRH）时射频源和天线负载间的阻抗匹配。分析了其阻抗匹配过程，并根据阻抗匹配条件得到天线输入阻抗变化时，三支节液态调配器的优化调配参数。利用数值模拟验证了在其他实验参数相同的条件下，三支节液态调配器的优化调配参数能使天线系统获得良好的匹配状态。

In the paper ,the impedance matching between RF source and antenna load was studied by adopting the three liquid stub tuner for ion cyclotron resonance heating (ICRH) on Tokamak based on the transmission line theory .The impedance matching process was analyzed ,and the optimized parameters of three liquid stub tuner for the changeable antenna input impedance were obtained according to impedance matching condition .The numerical simulation results show that optimized parameters of three liquid stub tuner can make the antenna system obtain good matching w hen the other experimental conditions are same .
