我认为你的绘图不必要地复杂，所以我从头开始重新绘制。你可能会发现下面的代码很有用 :-)

答案2
你不需要下面的代码transform canvas/scope
\begin{scope}[transform canvas={yshift=+4mm}]
\draw [->] (Wi_aRW_aux) -- (CERG) node [midway, above] {$\alpha_{RW}^{\text{EDS}} W_i \qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad$};
\end{scope}
用。。。来代替
\draw [->] (Wi_aRW_aux) |- (CERG) ;
要得到
现在您可以在箭头上方适当地插入标签/文本
该语法|-暗示了下行线和水平线的交叉
scope items/canvas code对其余节点重复相同步骤
有问题请回复
- 根据 OP 评论进行编辑
要使箭头终止于中心以外的另一点，请使用以下语法
\draw [->] (Wi_aRW_aux) |- ($(CERG)+(0pt,4pt)$) ;
终止点现在4pt位于y direction
使用这样的语法，你需要使用calc序言中的库\usetikzlibrary{calc}
