...
有 3 个命题，并且仅在命题 2 周围观察到不需要的垂直空间。仅供参考，该类risa使用twocolumn页面布局。我尝试使用\vspace{-1cm}等。并尝试更改参数值，发现低值（~0.5cm} 没有产生任何效果，但较高的值（~1cm）使命题跳得太多并与前面的文本重叠。我找到的最接近的答案是：删除定理周围的垂直空间，但这建议使用amsthm我无法使用的包。
请指出这里哪里出了问题。谢谢！
2016 年 12 月 27 日添加编辑： 我理解，出现在下一列顶部的方程（在 MWE 中给出）会迫使命题环境在前后留下不必要的垂直空间。请注意，MWE 中只有一个命题（而不是前面提到的三个）。

您的 mwe 的主要问题是由于多线方程。您应该不是使用eqnarray，它已被弃用，在对齐点周围有不好的间距。此外，它不能跨页/列分页。将其替换为 ams 环境 align*并使用指令\allowdisplaybreaks。
我将 的值改为更合理的值，并在命题和其证明之间theorempre/postskipamount添加了。请注意，证明环境不是作为定理结构实现的，而只是作为 trivlist 实现的，因此为负数：\vspace{-\topsep}\vspace
