| 摘 要： | 从电感的基本定义出发，推导了一个新的递推公式，可准确地对含磁芯线圈动态电感进行数值计算，并在纯电感、含有5匝磁芯线圈和含有17块铁氧体大环磁芯的感应腔在双脉冲励磁情况下分别计算了动态电感量，验证了该方法的可行性。通过电感值可反推出磁芯在各种情况下磁导率的变化曲线，从而确定磁芯的磁特性及其适用范围。

| Abstract: | From the basic define of the inductance,a new formula to calculate dynamic inductance is deduced,which can figure out the nonlinear inductance of winding with magnetic cores easily by numerical calculation.The dynamic inductances of a pure winding in 50 Hz alternating current,a 5 rounds winding with a ferrite core in 50 Hz alternating current and a coaxial cavity with 17 ferrite cores in double pulses exciting current are calculated to prove the accuracy of the formula.The magnetic core's permeability can be figure out from the inductance,which make it easily to confirm the applicability of the magnetic core. |
