[英]Is there a way to use latex expression of chemarr for `gitbook` format of bookdown package?
I would like to use latex expression of chemarr for gitbook
format of bookdown package.我想使用 chemarr 的 latex 表达式用于gitbook
格式的 bookdown package。
\begin{equation}
[C] + [R]
\xrightleftharpoons[k_{-1}]{k_1}
[CR] + [C]
\xrightleftharpoons[k_{-2}]{k_2}
[C2R]
(\#eq:multiplebinding)
\end{equation}
For PDF format, there is no problem of displaying the equation.对于 PDF 格式,显示方程没有问题。
On the other hand, for gitbook format there is an error message.另一方面,对于 gitbook 格式,有一条错误消息。
It's mainly because I cannot define the following yaml header for gitbook
format.这主要是因为我无法为gitbook
格式定义以下yaml header。
header-includes:
- \usepackage{chemarr}
Is there a way to use latex expression of chemarr for gitbook
format of bookdown package?有没有办法使用 chemarr 的 latex 表达式用于gitbook
格式的 bookdown package? If it's impossible, is there a way to use include_graphics
function and add equation numbering (say, 19.16 in this example)?如果不可能,有没有办法使用include_graphics
function 并添加方程式编号(例如,本例中的 19.16)?
Yihui Xie already gave a good hint to the solution:谢一辉已经给出了很好的解决方案提示:
Put this code into your document (where you want the equation to appear):将此代码放入您的文档中(您希望等式出现的位置):
$$
\require{mhchem}
\begin{equation}
[C] + [R]
\xrightleftharpoons[k_{-1}]{k_1}
[CR] + [C]
\xrightleftharpoons[k_{-2}]{k_2}
[C2R]
(\#eq:multiplebinding)
\end{equation}
$$
Needs to use the arrow of mhchem
instead of chemarr
since only the first is part of MathJax.需要使用mhchem
的箭头而不是chemarr
,因为只有第一个是 MathJax 的一部分。 But I think it should anyway be basically the same.但我认为无论如何它应该基本相同。
This method should work for all Latex commands supported by MathJax ( http://docs.mathjax.org/en/latest/input/tex/macros/index.html ).此方法适用于 MathJax 支持的所有 Latex 命令( http://docs.mathjax.org/en/latest/input/tex/macros/index.ZFC35FDC70D5FC69D2639883A822C7A )。
