大多数引文在 biblatex 和 biber 后端中不可见并标记为

Question

您的 MWE 包含选项

refsection=section,

这意味着文档中对\section（或）的每次调用都会启动一个新的。就引用和参考书目而言，它们构成了文档中完全独立的部分。一个文档中引用和参考书目中出现的内容不必出现在另一个文档的参考书目中。\section*refsectionrefsectionrefsectionrefsection

在您的文档中，该设置基本上减少到

\chapter{Chapter 1}
Daily living \cite{activities2017wiki}.
Systems \cite{muramatsu2011japan}.

\chapter{Chapter 2}
Dynamic Movement Primitives \cite{ijspeert2003learning}.
Calibration \cite{umeyama1991least} to align the frames.

%---------------------------------------------------
% new refsection
\newrefsection
\section{Section 1}
The controller can be \cite{ijspeert2013dynamical}.

\clearpage
\printbibliography[heading=bibintoc,title={All References}]

前半部分的引文与后半部分的引文完全无关。事实上，前半部分的引文没有参考书目，在这个设置 ( defernumbers=true,) 中，这意味着它们甚至没有编号（它们最终为 [0]）。它只ijspeert2013dynamical获得一个编号，因为它有一个相应的参考书目条目。

在您的 MWE 设置中，您似乎不想要自动refsection=section,。您可以\newrefsection根据需要手动发出。类似以下内容似乎更合适
