摘要
串联谐振电路在交流电压作用下,电感箱和电容箱存在损耗电阻,而通过对串联电路中电阻箱的阻值R的选择,可以降低电感箱和电容箱损耗电阻对Q值测量的影响,从而提高Q值测量的精确度,甚至在较高频率的串联谐振电路里也可使Q值测量值和准确值的百分误差E（Q）低于1%.
Under the effect of alternating current,the inductor and the capacitance in series loss. Through the choose of a standard dial resistor＇s -value, measuring precision of -value can the high frequency circuit,percentage error can be less than 1%.
