为了满足暗物质探测领域发展的需求，我们拟开发耦合全日球层磁流体模拟数据的银河宇宙射线太阳调制模型。新的太阳调制数值模型包含了外日球层对于银河宇宙射线的调制作用。利用暗物质粒子探测卫星(DAMPE）高能段电子能谱数据以及阿尔法磁谱仪(AMS02)的月平均质子能谱数据我们可以对数值模型进行校正，得到更加真实的数值模型参数。基于开发的银河宇宙射线太阳调制模型，我们计划模拟正电子受太阳调制出现的各向异性值；通过与太阳系临近源区（如中子星）引发的各向异性值对比，期望对观测到的”剩余正电子”现象提供合理的解释。

To meet the demands of the searching dark matter particle, we are planning to build a state-of-the-art galactic cosmic ray solar modulation model. This solar modulation model incorporate the Magnetohydrodynamics global heliosphere data into the Parker type galactic cosmic ray transport model, thus the modulation effect caused by the outter heliosheath will be taken into account. By fitting our numerical model to DAMPE's electron spectrum data and AMS02's monthly proton data, the free parameters in our numerical model will be constrained. .We will use this galactic cosmic ray solar modulation model to calculate the positron anisotropy caused by the solar modulation. The calculated heliospheric anisotropy factor will be compared with the anisotropy factor from the Solar system nearby positron source, i.e. pulsar. This comparison study will contribute to the understanding of the positron excess.
