为什么我的 Tikz 图片中的那些珠子互相重叠？

我使用 Tikz 创建了这排珠子，但是我的图片中发生了奇怪的事情，但我确实指定了不能相互重叠的位置。

% A "jazzy" picture of the stages of rust (presented for a high school level).
% Iron is red, oxygen is blue and electrons are black. At the left you see
% iron atoms with two oxygen molecules, then the electrons go to the oxygen molecules
% leaving oxygen ions and iron ions which then disolve.

我认为可能是因为圆的半径，所以将半径从 3.5 改为 1，但问题仍然存在。

那么为什么会发生这种情况呢？

我确实是通过 C 程序生成这些位置的，所以我认为没有数字是错误的。

谢谢你！

答案1

或者简单来说：

\foreach \x in {-155.0,-152.5,...,152.5}
\draw [oxygen] (\x,-40.0,0) circle (3.5);

答案2

\foreach通过使用以下内容替换循环来充分利用的功能：

\foreach \x in {0,...,123}
\draw [oxygen] (-155+\x*2.5,-40.0,0) circle (3.5);

答案1

答案2
