| + 这个[css文件](http://182.92.214.222/css/markdown.css)还不错 | |
| + 开源中国上不支持MathJax.js，可以把readme文件下载到retext 上看 | |
| ``` | |
| <script type="text/x-mathjax-config"> | |
| MathJax.Hub.Config({ | |
| config: ["MMLorHTML.js"], | |
| jax: ["input/TeX", "output/HTML-CSS", "output/NativeMML"], | |
| extensions: ["MathMenu.js", "MathZoom.js"], | |
| TeX: { | |
| equationNumbers: {autoNumber: "AMS"} | |
| } | |
| }); | |
| </script> | |
| <script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js"></script> | |

| ###希腊字母(\alpha) | |
| $\alpha , | |
| \beta, | |
| \gamma, | |
| \lambda, | |
| \xi, | |
| \pi, | |
| \mu, | |
| \phi, | |
| \omega$ 首字母大写的效果:$\Delta, \nabla, \Gamma$ | |
| 详细的希腊字母见下图: | |
|  | |
| --- | |
| ###上标下标(_和^), \{\}可以包含多个字母 | |
| $J_{i,h}$ | |
| $a^2$ | |
| $m^3$ | |
| --- | |
| ###关系符和运算符 | |
| $\le, | |
| \ge, | |
| \equiv, | |
| \ne | |
| $ | |
| $\ll, \gg, \in, \owns, \infty, \bot$ (无穷、垂直) | |
| $\pm, \mp, \div, \ast, \cdot, \cdots, \oplus$ | |
| $\quad$(空格) | |
| $\sqrt[3]{y}$ | |
| $\qquad$(大空格) | |
| $\frac{x}{x+1}$ | |
| --- | |
| ###大尺寸运算符(积分、极限、箭头) | |
| (只能是行间的。行内的极限，下标有问题) | |
| $$ \lim_{x \rightarrow 0}\frac{\sin x}{x}=1$$ | |
| $\int, \oint,\sum$ | |
| $\iint_a^b$ | |
| $\min, \max, \ln, \exp, \lg$ | |
| --- | |
| ###括号变大(\big, \Big, \bigg, \Bigg) | |
| $\big(， | |
| \Bigg(，$ | |
| $\big\}， | |
| \Bigg\}，$ | |
| $\big[, | |
| \Bigg[$ | |
| 自动调整括号大小(\left, \right): | |
| $1 + \left( \frac{1}{ 1-x^{2} }\right) ^3$ | |
| --- | |
| ###矢量 | |
| $\vec{ab}$ | |
| $\dot{x}$ | |
| $\hat{x}$ | |
| --- | |
| ###其他符号 | |
| $\overline{x+y}$ | |
| $\qquad$ | |
| $\underline{x+y}$ | |
| $\underbrace{ a+b+\cdots+z }_{26}$ | |
| $\qquad$ | |
| $\overbrace{ a+b+\cdots+z }_{26}$ | |
| --- | |
| ###对齐(&和两个\\),必须是行间的(用两个$符号) | |
| $$ \left[ | |
| \begin{array}{cc|c} | |
| 1&2&3\\ | |
| 4&5&6 | |
| \end{array} | |
| \right] | |
| $$ | |
| $$ | |
| y=\left\{ | |
| \begin{matrix} | |
| 1 & x = 0\\ | |
| -\frac{1}{x}& x \ne 0 \\ | |
| \end{matrix} | |
| \right. | |
| $$ | |
| 矩阵:(matrix, pmatrix，bmatrix，Bmatrix，vmatrix ) | |
| $$ | |
| y= | |
| \begin{vmatrix} | |
| 1 & x & x^2 \\ | |
| 1 & y & y^2 \\ | |
| 1 & z & z^2 \\ | |
| \end{vmatrix} | |
| $$ |
