Use the pair \lefts1 and \rights2 to match height of delimiters s1 and s2 to height of their contents, e.g.,

\left| expr \right| \left{ expr \right} \left\Vert expr \right.

4. 可变大小的符号(显示的公式显示更大的版本) 符号代码符号代码符号代码符号代码符号代码 ∑ \sum ∑\sum ∫ \int ∫\int ⨄ \biguplus ⨄\biguplus ⨁ \bigoplus ⨁\bigoplus ⋁ \bigvee ⋁\bigvee ∏ \prod ∏\prod ∮ \oint ∮\oint ⋂ \bigcap ⋂\bigcap ⨂ \bigotimes ⨂\bigotimes ⋀ \bigwedge ⋀\bigwedge ∐ \coprod ∐\coprod ∬ \iint ∬\iint ⋃ \bigcup ⋃\bigcup ⨀ \bigodot ⨀\bigodot ⨆ \bigsqcup ⨆\bigsqcup 5. 标准函数名称

函数名称应该出现罗马字体，而不是倾斜，例如：

正确：\tan(at-n\pi) --> tan ⁡ ( a t − n π ) \tan(at-n\pi) tan(at−nπ)

错误：tan(at-n\pi) --> t a n ( a t − n π ) tan(at-n\pi) tan(at−nπ)
