Super- and subscripts to the left of the base character can also be right-justified. To do this, the new commands &quot; lsub &quot; and &quot; lsup &quot; are used. Both commands have the same effect as &quot; sub &quot; and &quot; sup &quot; , except that they are left of the base character. See also &quot; a lsub 2 lsup 3. &quot;
基本字符左侧的上标和下标也可以右对齐。要进行此操作，可以使用新命令 &quot; lsub &quot; 和 &quot; lsup &quot; 。这两个命令与 &quot; sub &quot; 和 &quot; sup &quot; 具有相同的作用，唯一不同之处是上标和下标位于基本字符的左侧。请参阅 &quot; a lsub 2 lsup 3 &quot; 。
