我使用authoryear样式 ( biblatex)，我想从（文内）引文中删除“et al”，同时仅显示其中的第一个作者姓名。但我想在参考书目 ( maxbibname=3)中显示“et al.”

我用这一行\DefineBibliographyStrings{english}{andothers={}}从引文和参考书目中删除了“et al.”而我只想从引文中删除它（我需要的是 [de Gennaro, 2012] ）并保留“et al.”在参考书目中，如果有超过 3 位作者，则在第一位作者姓名后面（我需要：de Gennaro et al. (2012) .......）
答案1
\usebibmacro{name:andothers}删除引文中的“et al.”与从名称格式中删除一样简单labelname。
但是，如果只是在引用中隐藏“et al.”而不考虑排序和名称哈希，则会导致消歧字母出现问题（或者说缺少消歧字母）。最近发布的biblatex3.13 允许您忽略“et al.”以进行名称哈希生成和排序。请参阅https://github.com/plk/biblatex/issues/861。
相关选项是nohashothers和nosortothers。您可以在以下 MWE 中测试它们的效果。
