流程图发散和汇聚箭头

Question

问题： 我正在努力分割流程图中的箭头。我尝试查看类似的代码，但似乎无法重现它。如何才能得到理想的输出？

相关研究：

• 发散箭头，tikz/pgf - 流程图
• 调整 tikz 流程图中节点之间的垂直和水平空间
• 流程图中的汇聚节点和发散节点

编辑： 图表中根据您编辑的问题的需要添加了新节点。

在下面的 MWE（最小工作示例）中，与您的代码片段进行比较，进行了以下更改：

• 节点被组织成三个链（使用 TikZ 库chains），其中用于定位节点的positioning库及其语法（由此节点之间的距离相等，由确定node distance = <below> and <right>）
• 链中的节点通过包join中定义的指令绘制的箭头链接起来chains
• 节点之间的连接在四个地方通过使用代码断开suspend join
• 中未考虑的节点之间的连接join被单独绘制。

\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{arrows.meta,
                chains,
