你可以使用这个包https://ctan.org/pkg/unicode-math并选择一种数学字体。这样你就可以得到一组简洁的字形(只要字体设计师做得好)。你还应该考虑https://ctan.org/pkg/fontspec以便在数学模式和文本模式下一致地使用字体。以下示例生成衬线黑板粗体大写伽玛。
以下字形应该全部相同(并且在我看来它们看起来很相似)。
\documentclass{memoir}
\usepackage{amsmath}
\usepackage{unicode-math}
\setmathfont{Asana Math}
\begin{document}
$\BbbGamma \mathbb{\Gamma} \mathbb{Γ} \symbb{\Gamma} \symbb{Γ} ℾ \symbol{"213E}$
\end{document}
编辑:您还可以将 egreg 的解决方案应用于另一种与 CM 和 LM 很好地融合的被低估的字体,请自己比较它们:
\documentclass[landscape]{memoir}
\usepackage{amsmath}
\usepackage{graphicx,dsfont,amssymb,booktabs}
\newcommand\BbbGamma{\reflectbox{\rotatebox[origin=c]{180}{$\mathds L$}}}
\newcommand\BbbGammaVar{\reflectbox{\rotatebox[origin=c]{180}{$\mathbb L$}}}
\begin{document}
\begin{tabular}{*{16}{>{$}c<{$}} }
\toprule
\BbbGamma & \mathds h & \mathds k & \mathds 1 & \mathds A & \mathds B & \mathds C & \mathds D & \mathds E & \mathds F & \mathds G & \mathds H & \mathds I & \mathds J & \mathds K \\
\Gamma & \text h & \text k & \text 1 & \text A & \text B & \text C & \text D & \text E & \text F & \text G & \text H & \text I & \text J & \text K \\
\BbbGammaVar & \mathbb h & \mathbb k & \mathbb 1 & \mathbb A & \mathbb B & \mathbb C & \mathbb D & \mathbb E & \mathbb F & \mathbb G & \mathbb H & \mathbb I & \mathbb J & \mathbb K \\
\midrule
\mathds L & \mathds M & \mathds N & \mathds O & \mathds P & \mathds Q & \mathds R & \mathds S & \mathds T & \mathds U & \mathds V & \mathds W & \mathds X & \mathds Y & \mathds Z \\
\text L & \text M & \text N & \text O & \text P & \text Q & \text R & \text S & \text T & \text U & \text V & \text W & \text X & \text Y & \text Z \\
\mathbb L & \mathbb M & \mathbb N & \mathbb O & \mathbb P & \mathbb Q & \mathbb R & \mathbb S & \mathbb T & \mathbb U & \mathbb V & \mathbb W & \mathbb X & \mathbb Y & \mathbb Z \\
\bottomrule
\end{tabular}
\end{document}
上行:\mathds
,中行:Latin Modern
,下行:\mathbb
。
我的理解是,\mathds
实际上更接近于人们对黑板加粗只需在黑板上添加一个双击即可\mathbb
。
网站https://www.fileformat.info/info/unicode/char/213e/fontsupport.htm#对各种字体进行了比较。

警告:很久以前有这样的软件包,我不记得细节了。我猜它与这东西我真的不能告诉你为什么这个被放弃了,也许这次讨论可以帮助你。

当然结果并不像egreg 的回答但这里所有希腊字母都是双笔画字母。(那些觉得需要对我大喊大叫的人:这篇文章以一个很大的免责声明开始…… ;-)
答案4
这也有效:
\documentclass{standalone}
\newcommand\mygamma{$\mathrm{I} \hspace{-0.4ex} \Gamma$}
\begin{document}
\tiny \mygamma
\small \mygamma
\normalsize \mygamma
\large \mygamma
\Large \mygamma
\Huge \mygamma
\end{document}
产生这样的结果:
它也适用于其他字母,例如 R 或 N (实数或自然数):
\newcommand\myr{$\mathrm{I} \hspace{-0.4ex} \mathrm{R}$}
\newcommand\myn{$\mathrm{I} \hspace{-0.4ex} \mathrm{N}$}
