我正在使用 Springer 的 svjour3.cls 格式，当我编写文章时，我会在单独的页面中看到摘要和关键词，但它们不会出现在标题之后。

\begin{abstract}
Interactions are the building blocks of open environments. Finding reliable partners to interact with in open environments is a challenging task for agents, therefore, trust and reputation mechanisms are used to handle this issue. In literature, various trust mechanisms have been described. This article presents an extensive review of the most representative trust and reputation models presented in literature.

Answer 1

您发布的代码会在编译过程中导致错误消息，因此查看损坏的文档并担心缺少摘要是没有意义的。

如果错误得到修复，摘要将正确显示。具体问题如下：

• 你不能#1\end{tabular}}在序言中
• 你不能有空行\institute

除此之外，您还应该考虑实现 Micos 评论，它们不仅仅是“风格”问题，而且很容易导致问题。
