![在投影机的标题幻灯片后添加了许多空白幻灯片](https://linux22.com/image/471884/%E5%9C%A8%E6%8A%95%E5%BD%B1%E6%9C%BA%E7%9A%84%E6%A0%87%E9%A2%98%E5%B9%BB%E7%81%AF%E7%89%87%E5%90%8E%E6%B7%BB%E5%8A%A0%E4%BA%86%E8%AE%B8%E5%A4%9A%E7%A9%BA%E7%99%BD%E5%B9%BB%E7%81%AF%E7%89%87.png)
我刚刚开始演示,在标题幻灯片之后,似乎有超过 100 个“空白”(因为幻灯片底部有幻灯片标题和信息,但仅此而已)。知道原因吗,或者如何修复它?只有最后几张幻灯片符合我的要求。

答案1
语法\item<1.6->
错误。或多或少是巧合,它不会引发直接错误,但会导致所有额外的幻灯片。
overlay 参数用于指定项目应出现在哪些覆盖层上。数字应为整数。例如,如果您希望从第二个覆盖层开始出现项目符号,则应说\item<2-> ...
另一方面,如果您想手动指定幻灯片上显示的枚举号,请使用\item[1.3] ...
