我想在参考书目条目中的每个单元后面都加一个逗号，年份除外，条目末尾也是如此。我该如何实现？
这是我目前所拥有的。

我以为
\renewcommand*{\bibpagespunct}{%

会朝着正确的方向发展，但仅此而已。
我还有一些其他具体问题，但如果可以的话，我打算为每个问题开一个帖子。此外，如果有人想就改进配置提出意见，我也很乐意接受。

您的驱动程序使用\newunitpunct而不是\labelnamepunct，因此您无法在作者年份标签后合并不同的单位标点符号。您可能更愿意定制标准驱动程序，而不是完全重写驱动程序。使用 egreg 的xpatch软件包，这项任务变得特别容易，它（除其他外）etoolbox将 的修补命令扩展到参考书目宏、驱动程序、格式化指令和索引指令。
