通过用电阻星形联接与三角形联接等效变换法和等电位点变换法对同一对称线性电阻电路进行等效变换，可以发现，在对对称性电阻电路进行等效变换时，等电位点变换法可使等效变换过程和等效变换计算都大为简化。

At low temperature, both the positive and negative magnetoresistance effect can be observed for all the samples. The s-d exchange interaction induced spin-splitting, the formation of bound magnetic polarons, and the magnetic field suppressed spin-disorder scattering were competed for the MR behavior.

另外，在低温时所有样品都表现出较大的正磁电阻，我们认为正磁电阻效应是由于s-d电子交换相互作用引起的自旋劈裂造成的，而高场时出现的负磁电阻效应则可能归因于磁场导致的束缚磁极化子的破损和自旋散射的抑制。

We conclude that the s-d exchange_interaction_induced spin-splitting gives rise to positive MR, while the formation of bound magnetic polarons and the magnetic field suppressed spin-disorder scattering are responsible for the negative MR behavior under high field.
