最后，本文对单股丝铁磁绞线与多路弱磁检测传感器的复合磁特性进行了建模分析。
Finally, the stranded wires' magnetic figures of weak magnetism and the compound magnetic figures of stranded wires and weak magnetism sensors are studied.
由于在拉伸过程中复合芯只表现出弹性变化，而铝绞线要发生弹塑性变形，使导线的应力应变曲线上存在斜率的突然变化；
There is sudden change of slope in the stress-strain curve, because the core response in loading and unloading is entirely elastic, while the aluminum undergoes elastic-plastic deformation.
