我的文档是双倍行距的，在我将定理缩进定义下方后，产生了一个奇怪的空格。
这是我的代码；

\begin{theorem}\label{theo: modulo}
The \textbf{modulus} of a congruence $a=b(mod m)$ is the number $m$, with $m$>1 It is the "base" with respect to which a congruence is computed (i.e., m gives the number of multiples of a that are "thrown out"). \cite{mur}
\end{theorem}
\end{adjustwidth}

\begin{example}
Example of modulus, when computing the time of day using a 12-hour clock obtained by adding four hours to 9:00, the answer, 1:00, is obtained by taking 9+4=1(mod 12).
\end{example}
