摘　　要：地磁场非常微弱,约为10 5 T量级,这使得地磁倾角测量难度大、测量精度低.本文探讨了新型坡莫合金各向异性磁阻传感器在地磁倾角测量上的应用,实验发现新型磁阻传感器在地磁倾角测量中相比于其他方法具有操作简单,灵敏度高,精确性好等显著优点。实验除具有实际应用价值外,同时适合在高等学校大学物理实验中开设出相应的实验教学内容。Measuring of the geomagentic inclination is difficult and its exactness is low, because the earth-magnetic field is so weak and about 10^-5 T. This article has a discussion about the application of a new anisotropic magnetoresistive sensors for measuring the geomagentic inclination and the experiment finds that the new magnetoresistive sensors have the advantages of simple operation,high sensitivity and exactness when applied in the measuring of geomagentic inclination. Except its application value, the experiment is also suitable for the college physical experiment.
