+%%%%%%%%%%%%%%% 计数器知识 %%%%%%%%%%%%%%%%%%%%%%
+% 每次用 \newcounter{foo} 定义新计数器，内部都会定义这几个命令
+
+% \c@foo，储存计数器的值，初始值为 0
+% \thefoo，储存计数器输出时的格式，初始定义为 \arabic{foo}
+% \p@foo，储存计数器被引用时的前缀，初始定义为空
+% \cl@foo，储存「子计数器」列表（此处有简化），foo 自增时它的每个「子计数器」都会归零（详见「自动归零」一节），初始定义为空
+%% 关于计数器的自动归零
+% 如果还定义了计数器 \newcounter{bar}[foo]，那么 \cl@foo 里就有了 bar
+% \@addtoreset{child}{parent} 和 \@removefromreset{child}{parent} 可以把计数器 child 移入/移出 \cl@parent
+% \counterwithin* 和 \counterwithout* 和上一条里两个命令的功能类似，但它们在执行前会检查接受的两个参数是否为已定义的计数器。不加星号的版本会修改 \thechild，详见「输出格式」一节
+% 在使用 \stepcounter{parent} 和 \refstepcounter{parent} 时，parent 自增，同时归零\cl@parent 里的「子计数器」
+% \addtocount{parent}{1} 只自增 parent，没有归零其「子计数器」的效果
+% 归零实现为「对每个子计数器，先设为 -1，然后使用 \stepcounter 自增」，这样实现的「归零」功能是递归的
+% 递归的意思是，如果还有 \newcounter{grandchild}[child]，那么 \stepcounter{parent} 会将 child 和 grandchild 都归零

+%%%%%%%%%%%%%%% 计数器知识 %%%%%%%%%%%%%%%%%%%%%%
+% 每次用 \newcounter{foo} 定义新计数器，内部都会定义这几个命令
+
+% \c@foo，储存计数器的值，初始值为 0
+% \thefoo，储存计数器输出时的格式，初始定义为 \arabic{foo}
+% \p@foo，储存计数器被引用时的前缀，初始定义为空
+% \cl@foo，储存「子计数器」列表（此处有简化），foo 自增时它的每个「子计数器」都会归零（详见「自动归零」一节），初始定义为空
+%% 关于计数器的自动归零
+% 如果还定义了计数器 \newcounter{bar}[foo]，那么 \cl@foo 里就有了 bar
+% \@addtoreset{child}{parent} 和 \@removefromreset{child}{parent} 可以把计数器 child 移入/移出 \cl@parent
+% \counterwithin* 和 \counterwithout* 和上一条里两个命令的功能类似，但它们在执行前会检查接受的两个参数是否为已定义的计数器。不加星号的版本会修改 \thechild，详见「输出格式」一节
+% 在使用 \stepcounter{parent} 和 \refstepcounter{parent} 时，parent 自增，同时归零\cl@parent 里的「子计数器」
+% \addtocount{parent}{1} 只自增 parent，没有归零其「子计数器」的效果
+% 归零实现为「对每个子计数器，先设为 -1，然后使用 \stepcounter 自增」，这样实现的「归零」功能是递归的
+% 递归的意思是，如果还有 \newcounter{grandchild}[child]，那么 \stepcounter{parent} 会将 child 和 grandchild 都归零
