It seems that hexo can't work well with MathJaX when meets "_"

[veya2ztn]

下述代码包含了利用MathJax在markdown中显示数学公式，包括行间的使用$$ $$和行内的使用$ $

### Mathtype in List
+ Transverse Ising model
  $$
  H=-\sum_{i=1}^N (\sigma_{i}^x \sigma_{i+1}^x+g \sigma_{i}^z)
  $$
###Mathtype between lines
$$
H=-\sum_{i=1}^N (\sigma_i^x \sigma_{i+1}^x+g \sigma_i^z)
$$
### Mathtype inline in list
+ the particle has only two state $\left| \uparrow \right\rangle$ and $\left| \downarrow \right\rangle$, which means that $\sigma^z \left| \uparrow \right\rangle =1 \left| \uparrow \right\rangle$

Guessing Reason (原因猜测)

我用了一下最新的hexo-math支持的KaTex
I use the KaTex for testing

{% math %}
\begin{aligned}
H=-\sum_{i=1}^N (\sigma_i^x \sigma_{i+1}^x+g \sigma_i^z)
\end{aligned}
{% endmath %}

是可以实现的,然后我把所有的“_”符号给删去，
And I find it works. And if I delete all the script _ in LaTeX code

  $$
  H=-\sum^N (c^x c^y+g c^z)
  $$

mathJaX 就可以渲染了，所以问题在于hexo 在渲染的时候会把一些_给丢去，导致mathjax无法识别
it now can work.
So the problem is that when the hexo change the ".md" into web file the text in ".md" changed and some notation like "_" lost

同样困扰于这个问题，请问官方考不考虑解决一下呢？

将MathJax代码放置在<% raw %> <% endraw %> 之间。
