我正在使用natbib、microtype和flowframCharter BT 字體（透過命令\usepackage[bitstream-charter]{mathdesign}），並且得到以下結果：
我的主文檔中的其他實例顯示了這一點（也許這對您來說是一個線索）：
這是生成文件的程式碼：
\documentclass{extarticle}
\usepackage[margin=2cm]{geometry}
\usepackage[bitstream-charter]{mathdesign}
\usepackage{titlesec}
\usepackage[square, numbers, sort]{natbib}
\usepackage[letterspace=400]{microtype}
\usepackage{flowfram}
\newflowframe[1-4,6]{\dimexpr\textwidth/3-2\columnsep/3}{\textheight}{0pt}{0pt}[leftcolumn]
\setlength\parindent{16pt}
\begin{document}
\tolerance=10000
The manufacturing process is mostly subject to industrial legislation. Although the industrial process is a relatively large actor in the use of fossil fuels\citep{voorzanger2014}, the consideration of usage of renewable energy sources has many hurdles. The primary hurdle is the artificially deflated pricing on energy from non-renewables. Studies on feasibility of an adjustment and usage of renewable energy sources in the industrial sector have shown legislation is in fact a culprit, linking domestical industrial activities directly to current energy policies in place\citep{lund2009}. Furthermore, an example of an accessible legislation is the Extended Producer Responsibility (EPR), which indirectly circumvents additional energy costs by incentivising recollection and reuse of products\citep{kiddee2013}. Other directives also geared towards promotion of recycling and take-back more so circumvent a change in thinking of the legislative bodies dealing with the industrial energy sector, which is why a small portion of examples will be discussed in the recycling cycle rather than here.
However, mobile phones also use REEs, ranging from scandium for high performance equipment, to neodymium for ear speakers\citep{website:namibiaearth,humphries2010}: vital components for the production of a cellular phone. The shortage depletion risk ranges even further however. Estimates have shown that REEs range in depletion risk from 500 years for niobium to 7 years for antimony, considering stable demand\citep{website:mining}.

我在過時的 TL13 以及最近的 TL14 發行版上都產生了這個奇怪的間距問題。我總是對所有軟體包進行完整安裝。
我還注意到這個僅有的發生在左列，而不是我透過例如聲明的任何其他列：
\newflowframe{\dimexpr\textwidth/3-2\columnsep/3}{\textheight}{\dimexpr\textwidth/3-2\columnsep/3+\columnsep}{0pt}[centercolumn]
\newflowframe{\dimexpr\textwidth/3-2\columnsep/3}{\textheight}{\dimexpr2\textwidth/3-4\columnsep/3+2\columnsep}{0pt}[rightcolumn]
這是一個已知問題和/或有解決方法嗎？
答案1
\tolerance=10000意味著你明確地告訴 TeX 你不在乎換行有多糟糕。所以它不好也就不足為奇了。
刪除該\tolerance設定告訴 TeX 至少嘗試做出一些合理的輸出：
