\item[Acceleration /əkˌseləˈreɪʃ(ə)n/]
The rate of change of velocity over time.
\item[Adjacent /əˈdʒeɪ.sənt/]
Of a right-angled triangle,
it's the side between the angle under consideration and the right angle.

% \includegraphics[scale=1]{example-image}
% \end{center}
\item[Algebraic fraction]
A fraction that has an algebraic expression in the numerator and/or denominator.
\item[Allied /'ælaɪd/ angles]
The pair of angles in a C-- or U--shape formed when a straight line crosses two parallel lines.
These angles always add up to $180^\circ$.
\item[AND rule (for dependent events)]
The probability of both $A$ and $B$ happening
is equal to the probability of $A$ happening
multiplied by the probability of $B$ happening given that $A$ has happened.
\item[AND rule (for independent events)]
The probability of both $A$ and $B$ happening is
equal to the probability of $A$ happening
multiplied by the probability of $B$ happening.

\item[Angle bisector /baɪˈsektə/]
The line that cuts an angle into two equal smaller angles.
\item[Angle of depression/elevation]
The angle between a horizontal line and
the line of sight of an observer
at the same level looking down or up, respectively.
% \begin{center}
% \includegraphics[scale=0.82]{elevation_depression.pdf}
% \end{center}
\item[Arc /ˈɑːk/]
A part of the circumference of a circle.
\item[Arithmetic /əˈrɪθ.mə.tɪk/ (or linear) sequence]
A sequence where the terms increase or decrease by the same amount each time
(the common difference $d$).
\[
u_n = a + (n-1)d,
\]
where $a$ is the first term and $u_n$ is the $n$\textsuperscript{th} term.
\item[Asymptote /ˈæs.ɪm.təʊt/]
A straight line to show the values where the graph of a function is undefined.
\item[Average]
A way of representing a set of data with a central or typical value of the set.
The three common averages used are the mode, median and mean.

主要目的是为代码中的语音启用 unicode。因此，有人搜索了一下，发现我必须使用 xelatex 来编译它。
但是，有没有办法保留字体（而不是语音）使用
\usepackage[T1]{fontenc}
\usepackage{lxfonts}
以及\heiti我喜欢的页脚？他们似乎无法与 xelatex 配合使用？
简而言之，我希望输出与下图完全一致，并且 IPA 显示正确。这可能吗？
目前，如果我想显示 IPA，文档的其余部分看起来就很简单......
