| 摘 要： | 月球的磁场强度一般在1~10 nT（1 nT=10-9T）的范围内，最大磁场强度超过100 nT，强磁场区一般位于大的撞击盆地的对峙区域.月球样品的剩磁强度与铁的丰度呈负相关，在38~36亿年间形成的岩石样品剩磁强度最大.月球磁场的变化特征与月球的形成与演化有重要的关系，大碰撞学说来解释月球磁场的变化较合理.

| Abstract: | Several satellites observations demonstrate that the general intensity of lunar magnetism is 1~10 nT(1 nT=10~(-9)T),the largest concentration of strong fields over 100 nT and strong crustal magnetism fields are located in the antipodal region of large impact basins.Remanence intensity of lunar samples are negative related to the abundance of iron,materials which were formed between 3.6~3.8 Ga can gain strong remanent magnetism.The variation of lunar magnetism correlates critical relation of the evolution of moon,giant impact hypothesis is reasonable to explain the variation of lunar magnetism. |
