PDF 未生成但我没有看到错误！

我在添加 png 图像和连字符时遇到了很多麻烦，突然间，我添加了以下 tkiz 方案，当我添加最新的部分时，我开始得到一堆 Underfull vbox 和 Overfull xbox/hbox，我解决了它（或者我认为）但是当我添加方案的后半部分时，我的 pdf 不再生成了..我尝试将 tikz 图片分成图形并在它们之间强制使用 \pagebreak 和其他东西，但到目前为止没有任何效果...我同时添加了 tikz 方案（这似乎是问题所在）和我在最后得到的输出。

代码：

评论：

  1. 主要错误发生在语法“right of = some block”，但您使用了 right = xxcm of some block。

  2. 由于这些块都相似/相同，您可以使用 \tikzstyle={...} 来定义它，如定义的“块”和“总和”所示。但是，如果实际块大于定义的块，则在选项中添加所需的尺寸。（我留了一行供您检查。）

  3. 在第一个图中，我猜缺少一个分母，而是用 x 来代替。

  4. 一旦您理解了语法，您就可以修改它们以满足您的需要。

  5. 没有必要把它们放在图形环境中。
