求助：Tikz节点无法应用左/右对齐的问题

你的问题根源在于\makecell命令默认是居中对齐，它会覆盖TikZ节点设置的align=left属性，导致标题始终居中。下面提供两种直接有效的解决方法：

方法一：修改makecell的对齐参数 #

给\makecell添加[l]参数指定左对齐，让单元格内的内容跟随节点的对齐设置：

\usepackage{tikz}
\usepackage{makecell}

\begin{titlepage}
\setlength{\parindent}{0pt}

\begin{figure}
\begin{tikzpicture}[remember picture,overlay]
     \node at (current page.center)      {\includegraphics[scale=0.2]{example-image-10x16}};
     \node[fill=white, scale=2, text=red, text width=94mm, align=left] at ([xshift=7mm,yshift=30mm]current page.center) {\makecell[l]{\textbf{The title goes here and it is very}\\textbf{long so it covers two lines}\\Xhline{2\arrayrulewidth}\\[-18pt]\scalebox{.35}{\textbf{\fontfamily{phv}\selectfont DEPARTMENT OF SOME ENGINEERING DISCIPLINE $\vert$ MY UNIVERSITY}}\\[-7pt]\scalebox{.35}{\textbf{\fontfamily{phv}\selectfont MY NAME HERE $\vert$ NAME OF PROGRAM}}}};
\end{tikzpicture}
\end{figure}

\end{titlepage}

方法二：移除makecell直接利用节点属性 #

你已经给TikZ节点设置了text width=94mm和align=left，完全可以去掉\makecell，直接用\\换行，节点会自动处理文本的左对齐和换行：

\usepackage{tikz}
\usepackage{makecell}

\begin{titlepage}
\setlength{\parindent}{0pt}

\begin{figure}
\begin{tikzpicture}[remember picture,overlay]
     \node at (current page.center)      {\includegraphics[scale=0.2]{example-image-10x16}};
     \node[fill=white, scale=2, text=red, text width=94mm, align=left] at ([xshift=7mm,yshift=30mm]current page.center) {\textbf{The title goes here and it is very}\\textbf{long so it covers two lines}\\Xhline{2\arrayrulewidth}\\[-18pt]\scalebox{.35}{\textbf{\fontfamily{phv}\selectfont DEPARTMENT OF SOME ENGINEERING DISCIPLINE $\vert$ MY UNIVERSITY}}\\[-7pt]\scalebox{.35}{\textbf{\fontfamily{phv}\selectfont MY NAME HERE $\vert$ NAME OF PROGRAM}}};
\end{tikzpicture}
\end{figure}

\end{titlepage}

两种方法都能实现标题的左对齐，你可以根据习惯选择其中一种。
