摘　　要：用复数伏安比法对ＲＸ７／０型可变标准电容箱在１ＭＨｚ范围内进行测试，其满容量时的谐振频率ｆ＿０≈３００ｋＨｚ。当ｆ＜ｆ＿０时，电容箱呈容性；当ｆ＞ｆ＿０时，电容箱呈感性；其阻抗在谐振点有极小值。The RX7/0 variable standard capacitor device is measured by using of complex rate ofvolt-ampere within the 1MHz range,its resonance frequency(f_0)is 300kHz in the maximumcapacity. When f<f_0, the capacitor device has capacitor characteristic;When f>f_0, it hasinductance characteristic;The impedance is get minimal in the resonance frequency.
