平均能量损失

Question

相关关于使用 BibTeX 在参考文献部分呈现引文摘要的问题和它的答案，我想知道如何使用在参考文献部分添加引文摘要BibLaTeX。

有没有什么办法可以实现这样的引用部分：（1）引用的项目在书目信息后有完整的摘要，（2）摘要以粗体标题开头“抽象的“以及换行符，如下所示？

biblatex-apa默认情况下不显示该abstract字段，但它会annotation在条目末尾显示扩展注释的字段。

我们可以重新定义打印宏，annotation以便也打印abstract存在的情况。

\documentclass{article}
\usepackage[backend = biber, style = apa, citestyle = numeric]{biblatex}

\renewbibmacro*{annotation}{%
  \ifboolexpr{       test {\iffieldundef{annotation}}
              or not togl {bbx:annotation}}
    {}
    {\begingroup
     \togglefalse{blx@bibliography}%
     \newline
     \setunit{}%
     \printfield{annotation}%
     \endgroup}
  \iffieldundef{abstract}
    {}
    {\begingroup
     \togglefalse{blx@bibliography}%
     \setunit{%
       \par
       \vspace{0.5\baselineskip}}%
     \bibstring[\mkbibbold]{abstract}%
     \setunit{\newline}%
     \printfield{abstract}%
     \endgroup}}

\DeclareFieldFormat{labelnumberwidth}{\mkbibbrackets{#1}}

\defbibenvironment{bibliography}
  {\list
     {\printtext[labelnumberwidth]{%
      \printfield{labelprefix}%
      \printfield{labelnumber}}}
     {\setlength{\labelwidth}{\labelnumberwidth}%
      \setlength{\leftmargin}{\labelwidth}%
      \setlength{\labelsep}{\biblabelsep}%
      \addtolength{\leftmargin}{\labelsep}%
      \setlength{\itemsep}{\bibitemsep}%
      \setlength{\parsep}{\bibparsep}}%
      \renewcommand*{\makelabel}[1]{\hss##1}}
  {\endlist}
  {\item}
