latex 对照表

\(\mathrm{\LaTeX}\) Mathematical Symbols 速查对照表（支持 F3 搜索）

说明：非常用符号未包含在基础 \(\mathrm{\LaTeX}\) (NFSS) 中，完整排版环境需引入 \usepackage{amssymb}（\iint 需 \usepackage{amsmath}）；在 latexlive.com 与 博客园 (cnblogs) 中均可直接使用。
检索提示：按 F3（或 Ctrl+F）可直接搜索任意 LaTeX 命令（如 \alpha、frac、approx、subset）或各节上方的 中文关键词（如 分式、约等、真子集、因为）。
