# 数学公式

$\frac{1}{\eta}<\theta<1$

$\frac{\partial{\ln{Z(T,H)}}}{\partial{H}}=\frac{1}{Z}\sum_{\{s_i\}}{\frac{\sum_{i=1}^N {s_i}}{kT}}\exp{(-\frac{\sum_{\{s_i\}}E_{\{s_i\}}}{kT})}=\frac{\langle M\rangle}{kT}$

# 多次引用同一文献

To give a footnote a unique identifier, use <ref name="name">. You can then refer to the same footnote again by using a ref tag with the same name. The text inside the second tag doesn't matter, because the text already exists in the first reference. You can either copy the whole footnote, or you can use a terminated empty ref tag that looks like this: <ref name="name" />. The quotes are not required (but still correct) if the name contains no embedded spaces. The space before the closing "/" may be omitted.
