我有一个非常大的文本语料库，我正在对它进行微调，以适应排版等。据我所知，缩写，如 ACAB，需要有字母间距。我找到了一些令人信服的设置，但是！我目前的设置需要我\track{ACAB}在每个缩写周围说。我担心我在某个地方省略了它，文本看起来会不一致。此外，将它插入到尚未插入的地方是一项艰巨的工作。截至目前，我已将宏设置\track为不执行任何操作并寻找其他选项。
有没有办法自动调整一组连续大写字母的字母间距？这可以是某种缩放大写字母的字距对之类的操作。我宁愿不增加大写字母周围的字母间距，因为它在任何地方都有效，而且下一个字母也是大写字母。
我不喜欢使用小写字母来表示缩写——是的，我知道，但排版也是一个个人喜好问题，而我对特定应用程序和字体的喜好告诉我不要这样做。因此，所讨论的缩写只是在文本正文字体中以大写字母排版。如果因此有一个围绕它们的 LaTeX 宏，我早就处理好了。
再次：我正在寻找一种全局字距调整解决方案，它不需要在每个需要调整的缩写周围都使用宏。在 pdfLaTeX 和 中是否也可以这样做microtype？
举个例子：
\documentclass{article}
\usepackage[activate={true,nocompatibility},kerning=true,spacing=true,tracking=true,final]{microtype}
\microtypecontext{spacing=nonfrench}
%% this is my font setting, can be disabled if the font is not there
\usepackage[garamond]{mathdesign}
\usepackage[full]{textcomp}
\usepackage[swashQ]{garamondx}
\usepackage[T1]{fontenc}
\usepackage[supstfm=NewG8-sups]{superiors}
%% the old solution
%% requires putting the \track macro around each abbreviation
%% this is too much work and also error-prone

Thus, arteriolar endothelia were described to express Sca-1, but not
VEGFR3 or CD201, while sinus endothelia were positive for VEGFR3 and
CD201, but not for Sca-1. Tie-2 (CD202b) was preferentially detected
in arterial, but not in sinusoidal endothelial cells In humans, bone
marrow microvessels have up to now been primarily demonstrated in
small paraffin-embedded biopsies using monoclonal antibodies (mAbs) to
CD34. We have now used undecalcified serial sections of a
representative iliac crest specimen spanning about FOOBAR and a
combination of antibodies against CD34 and CD141 to analyse the 3D
arrangement of microvessel endothelium in human bone marrow.

更新：我现在正在重新评估我是否需要字母间距。不可否认，无字母间距的首字母缩略词看起来有点丑陋，但大多数其他选项也不太讨人喜欢。这是一张屏幕截图，是我手动调整字母间距的方式，以及 tugboat 首字母缩略词渲染的黑客移植版本。
完整跟踪\textls来自microtype，“我的”跟踪是\DeclareRobustCommand{\track}[1]{\textls[20]{#1}}。“跟踪”不太合适，可能更好的名称是“字距调整”或“大写字母间距”...

所以，现在我不仅在思考“如何做这件事” ，而且还在考虑“我是否应该做这件事”。很抱歉给大家带来不便。
