摘　　要：本文主要介绍利用自主设计的拉压实验平台对巨磁电阻阻值随外界压力的变化情况进行研究。通过在不同的压力下测量巨磁电阻的伏安特性,得到一些结论,为以后进一步的研究开辟新方法新理念。This article mainly introduced that use the independent design to pull the pressure to test the platform to conduct the research to the great magnetism resistance resistance number along with the ambient pressure change situation. Through surveys the great magnetism resistance under the different pressure a voltage-current characteristic, obtains some conclusisons, will open the new method new idea for the later further research.
