摘　　要：在合理的简化的模型下导出空间电荷透镜中磁流体方程,由此证明在空间电荷透镜中能够建立线性径向电场。电场边界条件是重要的,并导出实际的边界电位值。由负电极和磁镜中构成的空间电荷透镜初步满足上述要求。The magneto-fluid equation for space charge lens has been derived from a reasonable and simple model. It is testified that establishing linear electric strength is possible in the space charge lens. Electric boundary is very important for establishing such a electric field. The real value of lens boundary is calculated out. The space charge lens consisting of negative electrode and magnetic mirror is satisfy essentially above boundary condition.
