MAA 填充模板字体样式问题

Question

我正在使用美国数学协会的“填充模板”写一些东西。但它不能正常工作 - 我无法将文本设为斜体或粗体。 和 都\it不起作用\textit。

可能存在什么问题？

\noindent {\large \bf \textsf{A Consequence of the Pythagorean Theorem}}\\


\noindent The well known Pythagorean theorem $a^2 + b^2 = c^2$ relates the lengths of the three sides of a right triangle. We present an exciting consequence of this result, namely, that if two of the three sides of a right triangle have lengths that are even integers, then the third side must be of even length as well. 

To see this, suppose that $a$ and $b$ are even; then $a = 2a'$, $b = 2b'$, where $a'$ and $b'$ are positive integers.  Hence
\[   c^2 = (2a')^2 + (2b')^2  = 4(a'^2 + b'^2).     \]
The result when the hypotenuse and one of the legs are of even length is proved similarly.

Answer 1

您在文中没有提到它，但我根据您的标记推测您使用了 xelatex。

您正在使用的软件包非常旧，并且没有为 xelatex 设置，如果您尝试，您会收到有关字体的多个警告，并且输出是

如果你使用 pdflatex 那么输出是

但请注意，使用的标记非常奇怪，，，\bf不应在乳胶中使用，并且永远不应在段落末尾使用，否则会产生警告\noindent\rightline\\

 Underfull \hbox (badness 10000) in paragraph at lines 28--29

和糟糕的输出。

Answer 2

如果您想使用 XeLaTeX 编译它，那么您应该声明合适的字体。

\usepackage{maa-monthly}% https://www.maa.org/sites/default/files/pdf/pubs/maa-monthly.sty

\usepackage{unicode-math}
\setmainfont{STIX Two Text}

如果系统中没有安装字体，则可以进行声明（使用最新的 TeX Live 或 MiKTeX 发行版）
