考虑了存在边界的不均匀大尺度磁场中的扩散宇宙射线传输。针对带有对流项的修正电报方程导出了反射和吸收边界条件。给出了说明性边界问题的解析和数值解。讨论了存在边界的情况下聚焦宇宙射线传输的电报近似的适用性和准确性，并指出了建模宇宙射线传输的潜在应用。
Diffusive cosmic-ray transport in nonuniform large-scale magnetic fields in the presence of boundaries is considered. Reflecting and absorbing boundary conditions are derived for a modified telegraph equation with a convective term. Analytical and numerical solutions of illustrative boundary problems are presented. The applicability and accuracy of the telegraph approximation for focused cosmic-ray transport in the presence of boundaries are discussed, and potential applications to modeling cosmic-ray transport are noted.
