如何将参考文献中的 PhD 论文改为 PhD Thesis？

Question

考虑以下 MWE：

\begin{filecontents}[overwrite]{\jobname.bib}
 @phdthesis{author_book,
  title = {Book's title},
  author = {Author, Some},
  publisher = {Publisher},
  date = {2005},
 }
 
\end{filecontents}
\documentclass{article}
\usepackage[isbn=false,giveninits=true,uniquename=init,style=authoryear-comp,backend=biber,natbib,maxbibnames=99,maxcitenames=3,hyperref=true]{biblatex} % To get fancy bibliography as desired.
\addbibresource{\jobname.bib}

\begin{document}

\citet{author_book}
 
\printbibliography
 
\end{document}

如下图所示，结果为“PhD thesis”，其中单词论文不是大写。我想得到这个词论文大写（即，论文）。 我怎样才能做到这一点？

谢谢你们！

Answer 1

一种简单的方法是宣布你想要将单词大写：

 @phdthesis{author_book,
  title = {Book's title},
  author = {Author, Some},
  publisher = {Publisher},
  date = {2005},
  type = {PhD Thesis},
 }

对于单个条目，这是最简单的方法。否则

\begin{filecontents}[overwrite]{\jobname.bib}
 @phdthesis{author_book,
  title = {Book's title},
  author = {Author, Some},
  publisher = {Publisher},
  date = {2005},
 }
\end{filecontents}

\documentclass{article}

\usepackage[
  isbn=false,
  giveninits=true,
  uniquename=init,
  style=authoryear-comp,
  backend=biber,
  natbib,
  maxbibnames=99,
  maxcitenames=3,
  hyperref=true,
]{biblatex} % To get fancy bibliography as desired.

\DefineBibliographyStrings{english}{
  phdthesis = {PhD\addabbrvspace Thesis}
}

\addbibresource{\jobname.bib}

\begin{document}

\citet{author_book}
 
\printbibliography
 
\end{document}
