如何在论文标题页中插入个性化居中水平分隔线

Question

我试图插入一条水平线来分隔我的论文标题和副标题，副标题只是描述这是一篇博士论文。然而，我尝试了各种命令\hrule，\hfill但收效甚微。

我希望该行如下所示：

• 该线不会立即附加到标题（如在 MWE 中），而是可以定制为短距离。
• 与 之间的距离可自定义\subtitle。
• 对于不跨越文本空间宽度并且居中放置的线，其距离可以自定义，但可以是文本空间宽度的 1/3。

可能我希望它可以是一条花哨的线，比如双线，上面一条加粗，下面一条不那么粗，但目前这并不那么重要。

以下是我的 MWE，谢谢。

以下代码能产生您想要的结果吗？

顺便说一句，由于您使用setspace，因此您应该使用onelinespacing命令而不是\linespread：它负责处理脚注行距和其他一些间距参数。
