摘要： \sum默认上下标是写在右上角和右下角的。在独立公式中，则是写在上面和下面的。对于行内公式，我们也可以强制用\limits让其上下表标出现在上面和下面。Note：\sum\nolimits的作用相当于\sum。e.g. $\sum\limits_{i=1}^n a_i$。另外，如果想把一般的操作符也进行如上变更，只须把你的操作符用\mathop{}括起来即可。e.g. $\mathop{\cup}\limits_{i=1}^n a_i$.3.编排矩阵或行列式, 就会遇到特别的省略号, \cdots, \vdots, \ddots就是三个方向的省略号. 而\ldots是比 \cdots低一点的省 阅读全文

They are, however, often a very wrong way to represent subtle but important differences.Image viaWikipedia.Revolutions, a blo 阅读全文

摘要： If you right-click on the project there should be a "Qt Project Settings" option (or similar - I use the german version) near the end of the context menu. In there you can set the Qt version that this specific project uses. Is this one possibly not set correctly? 阅读全文

摘要： 问题:双击release下的exe文件报错，无法定位程序输入点与动态链接库QtCore4.dll上，而debug下没问题 将release下的exe文件拷到qt的bin目录下，再双击就没问题了.我的回复:我也出现了这个问题.原因很有可能是你环境变量中的系统变量PATH设置问题.我开始安装QT没有出现这个问题,用了一段时间就出现罗.觉得是 QtCore4.dll 链接错误,意思是说 release下的可执行程序链接的QtCore4.dll不是QT安装目录下的/bin中的QtCore4.dll.后来一查找,发现最近安装的CTEX软件中也有QtCore4.dll,找到原因了.所以,把qt下的库路径添 阅读全文
