嗨，我希望有人能帮我解决两个问题，第一个是删除摘要标题并将其清空。我已经尝试过 \renewcommand{\abstractname}{} 和 \renewcommand{\absnamepos}{empty} 但这没有任何效果，而且使用摘要包时整个文档都会变得混乱，所以我宁愿不使用它。
另一个原因是必须在纸张顶部插入横幅，但是这会导致整个页面只有顶部的横幅，而我找不到删除空间的方法。
任何帮助都将受到赞赏。
亲切的问候。
答案1
TL;DR：您正在使用一个不灵活的模板类，这使得修改它变得非常困难。
对于您的第一个问题：该类对包含摘要标题的命令使用了非典型命名。它不使用通常的\abstractname命令，而是定义自己的命令。将其放在\abstracttitle{}您的序言中将定义一个空名称并使其消失。
其次，吼叫frontmatter程序的编码方式非常奇怪。给定的命令（包括abstract等）将存储它们的信息，并全部它将通过\maketitle自动发出的命令进行排版在最后的fronmatter。此命令包括一个\clearage，使它从新页面的顶部开始。除了文档中给出的选项外，您几乎没有选项可以修改标题页的外观。插入横幅需要摆弄类源代码，因此从头开始自己创建标题页可能更容易。
编辑：我发现了一个非常（非常！）棘手的解决方法，但如果您想坚持使用此模板，您无能为力。此示例产生了我认为您想要的结果。但它不稳定，因此其他东西可能会损坏：
