数学模式下的多行文本

Question

我的论文中的一个假设需要很长的文字。有没有办法很好地格式化它？我想将其保持在数学模式，以便它看起来与其他假设相同，并且我可以用标签引用它。

谢谢！

\begin{align*}
\text{The joint distribution of $(D, M_1, M_2, \theta)$ admits a bounded density with respect to the product measure of the counting measure on the set $\{0,1\}$ and the Lebesgue measure on $\mathcal{M}_1 \times \mathcal{M}_2  \times \Theta$. All marginal and conditional densities are also bounded.} \tag{A1}
\end{align*}

Answer 1

单行方程式永远不应该出现align（即使没有\text要求）。

你可以使用

\begin{equation}
\parbox{.7\textwidth}{The joint distribution of $(D, M_1, M_2, \theta)$ admits a bounded
 density with respect to the product measure of the counting measure on the set
 $\{0,1\}$ and the Lebesgue measure on $\mathcal{M}_1 \times \mathcal{M}_2
  \times \Theta$. All marginal and conditional densities are also bounded.}
 \tag{A1}
\end{equation}

\newthorem尽管我可能会考虑使用用数学模式定义的环境来实现这一点。
