1、（a）证明静电场的唯一性定理
（b）证明无穷大空间中静电场的唯一性定理，要求ρ ~ 1/r^q，q ≥ q_c，求q_c
（c）利用叠加原理和电像法算电势分布

2、写出接地平面的Green函数，算一个电势分布，作轴外展开

3、从电偶极子的?δ表达式算电势分布、单极矩、偶极矩，然后把电偶极子放在接地平面附近，算能量、力（搞清楚镜像偶极子的方向，能量和力记得除以2）

4、用双线性组合构造Green函数，证明L G = δ，然后在一个接地长方体内，构造z方向的Green函数，然后构造三维的Green函数（把三个方向的一维Green函数相乘，记得乘4 π），然后算一个电势分布

Start by reproducing the issue with the linked chinese-example.zip and trace the ZIP conversion entry point that emits the displayed file names. Confirm that Chinese names remain readable in the generated Markdown, and add or update coverage where the ZIP handling is exercised if the repository exposes such a test.
