以下是您提供的内容的中文翻译：

"manim可以使用LaTeX，LaTeX可以使用Tikz，Tikz可以沿着路径排版文本，所以..."

  1. class Test(Scene):
  2.     def construct(self):
  3.         s = "巴士上的车轮转" + "，".join(["一圈又一圈"]*3)
  4.         txt = " ".join(
    展开收缩
    *7)
  7.         myTexTemplate = TexTemplate()
  8.         myTexTemplate.add_to_preamble(r"\usepackage{tikz}\usetikzlibrary{decorations.text}")
  9.         tikz_code = rf"""\sffamily\scriptsize
  10.             \begin{{tikzpicture}}[
  11.             decoration={{
  12.                 reverse path,   
  13.                 text effects along path,               
  14.                 text={{{txt}}},
  15.                 text effects/.cd,
  16.                 text along path,
  17.                 }}
  18.             ]
  19.             \draw [decorate] (0,0) 
  20.                 \foreach \i [evaluate={{\r=0.3+(\i/1500);}}] in {{0,5,...,4490}}{{ -- (\i:\r)}}; 
  21.             \end{{tikzpicture}}
  22.         """
  24.         t = Tex(tikz_code, tex_template=myTexTemplate).scale(0.8)
  25.         self.play(Write(t), run_time=10)
  26.         self.wait(2)

结果：

英文:

Well, manim can use LaTeX, and LaTeX can use Tikz, and Tikz can typeset text along a path so...

  1. class Test(Scene):
  2.     def construct(self):
  3.         s = &quot;The wheels on the bus go &quot; + &quot;, &quot;.join([&quot;round and round&quot;]*3)
  4.         txt = &quot; &quot;.join(
    展开收缩
    *7)
  7.         myTexTemplate = TexTemplate()
  8.         myTexTemplate.add_to_preamble(r&quot;\usepackage{tikz}\usetikzlibrary{decorations.text}&quot;)
  9.         tikz_code = rf&quot;&quot;&quot;\sffamily\scriptsize
  10.             \begin{{tikzpicture}}[
  11.             decoration={{
  12.                 reverse path,   
  13.                 text effects along path,               
  14.                 text={{{txt}}},
  15.                 text effects/.cd,
  16.                 text along path,
  17.                 }}
  18.             ]
  19.             \draw [decorate] (0,0) 
  20.                 \foreach \i [evaluate={{\r=0.3+(\i/1500);}}] in {{0,5,...,4490}}{{ -- (\i:\r)}}; 
  21.             \end{{tikzpicture}}
  22.         &quot;&quot;&quot;
  24.         t = Tex(tikz_code, tex_template=myTexTemplate).scale(0.8)
  25.         self.play(Write(t), run_time=10)
  26.         self.wait(2)

Result:
