摘　　要：本文介绍了基于月尘扬起机制的"动态喷泉模型",分析了月尘扬起的过程;最后提出了"带电月尘活动电磁感应模型",计算得到月面明暗交界处带电月尘活动产生的感应磁场强度小于0.0064nT.本文证明带电月尘的活动对月球磁场的影响微小,可以忽略.We introduced the distribution characteristics of the lunar magnetic field.Based on the ＂Dynamic Fountain Model＂ for lunar-dust levitation processes,we analyzed the detailed movement sequence of lunar-dust.For the charged lunar-dust,the designed ＂Electromagnetic Induction Model for the Active Charged Lunar-Dust＂ was applied to calculate the intensity of the induced magnetic field at terminator areas on the Moon.The intensity of the induced magnetic field from the model is smaller than 0.0064 nT.It suggests that the contribution of the charged lunar-dust Moon to the lunar magnetic field is small and can be neglected.
