我怀疑你正在经历这样的事情：

\documentclass[xcolor={table,dvipsnames}]{beamer}
\usepackage{blkarray}

\usepackage{makecell}

\begin{document}
\begin{frame}
    \[
    \renewcommand\arraystretch{1.2}
\Bigl[\tilde{d}_{ij}\Bigr]_{m\times n} = 
\begin{blockarray}{ccc cc}
    & C_1 & C_2 & \dots & C_n       \\
    \begin{block}{c[cc cc]}
A_1 & \tilde{d}_{11}    & \tilde{d}_{12}    & \dots     & \tilde{d}_{1n}    \\
A_2 & \tilde{d}_{21}    & \tilde{d}_{22}    & \dots     & \tilde{d}_{2n}    \\
\vdots
    & \vdots            & \vdots            & \vdots    & \vdots            \\
A_m & \tilde{d}_{t1}    & \tilde{d}_{t2}    & \dots     & \tilde{d}_{mn}    \\
    \end{block}
\end{blockarray}
    \quad\text{for}\quad \makecell[l]{i=1,2,\dots,m \\
                                   j=1,2,\dots,n \;.}
    \]
\end{frame}
\end{document}

编辑： 您的文档示例有几个严重缺陷：

• 方程不需要在center环境内
• 浮动环境table不必插入方程中

上面的 MWE 更正了这些错误。还从您的文档中创建了 MWE（最小工作示例），其中文档的序言仅缩减为必要的包。

关于你的序言：这可能是重大的清理工作。例如：

\documentclass[xcolor={table,dvipsnames}]{beamer}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage{lmodern}
\usepackage{pdflscape}

% math
\usepackage{blkarray}
\usepackage{mathtools,  % if you really need it, amsmath is loaded by beamer
            amssymb,amsthm,amsfonts}
% tables
\usepackage{rotating}
\usepackage{ragged2e}
\usepackage{booktabs, longtable, makecell, multirow, tabularx}
% drawings
\usepackage{pstricks,pst-grad}
% units
\usepackage{siunitx}

\usepackage{etoolbox}
