摘　　要：以电感为敏感元件测量微弱电流的混沌测量系统,具有极高的精度和良好的线性度。因此,为了更好地运用此混沌测量系统,深入地探讨其特性,指出测量微弱直流电流仅达μA数量、有些电流值无法测量和测量的精度不一致的缺点,为改善此测量系统,提出以模拟电感替代电感方法。The chaotic system, with the inductor as sensitive parameter to measures the weak direct current, has good precision and linearity when. So we study its features, and reveal its shortcomings. In the first, that the system cant measure the current that is lower than 1 . In the second , some current cannot being measured. In the third, the precision iant similar. Thus, we develop the principle with the simulated inductor being instead of inductor.
