仅显示 Biblatex 引文中的最后两年数字

我正在写一篇文章，其中引用了几个标准，例如

@STANDARD{en1990,
  title = {EN 1990: Eurocode: Basis of Structural Design},
  organization = {Comit\'e Europ\'een de Normalisation (CEN)},
  address = {Brussels, Belgium},
  year = {2002}
}

和

@STANDARD{aci318-63,
  title = {ACI 318-63: Building Code Requirements for Reinforced Concrete},
  organization = {American Concrete Institute (ACI)},
  address = {Farmington Hills, Michigan, USA},
  year = {1963}
}

我使用biblatex。style=authoryear我可以将第一个引用为\parencite*[EN 1990:][]{en1990}，这会导致引用以连续文本的形式出现(EN 1990: 2002)，这是此标准通常的引用方式。但是，这对第二个示例不起作用，因为此标准的样式为 ，ACI 318-63并且\parencite*只会显示整个年份，而不是仅显示最后几位数字。

有没有办法改变某个引文的年份格式？甚至有没有办法覆盖/修改默认引文文本？

我有点怀疑我需要创建一种自定义样式，并带有一个额外的字段来保存应该出现在引用中的格式化年份，但我希望有一种简单的方法来做到这一点，而不必花费太多时间自定义biblatex样式。

我不会使用第二个可选的引用参数来生成“短标题”，而是使用字段shorttitle。然后，根据您是否添加了年份的最后几位数字shorttitle，我将使用\parencite（无星号版本）或自定义\parencitetitle命令。

\documentclass{article}

\usepackage[style=authoryear]{biblatex}

\DeclareCiteCommand{\parencitetitle}[\mkbibparens]
  {\boolfalse{citetracker}%
   \boolfalse{pagetracker}%
   \usebibmacro{prenote}}
  {\ifciteindex
     {\indexfield{indextitle}}
     {}%
%   \printfield[citetitle]{labeltitle}}
   \printtext[bibhyperref]{\printfield[citetitle]{labeltitle}}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

\DeclareCiteCommand*{\parencitetitle}[\mkbibparens]
  {\boolfalse{citetracker}%
   \boolfalse{pagetracker}%

     {}%

  {\multicitedelim}

您可以定义一个新的格式指令来打印一年的最后两位数字，但您需要自定义样式以将其纳入其中。

使用构成引文标签的字段是避免样式更改的另一种方法。当或不可用时，该label字段可用作后备。该字段将覆盖整个引文标签。authoryearauthoryearshorthand

以下文档给出了一些示例。您可能希望尝试使用label、shorthand和字段title，execute以避免参考书目中的数据重复。

  \citeyear}

% Customize label-year delimiter in cite bibmacro
