For a normed space \(X\), an isometric isomorphism can be defined from \(X\) to its second dual space \(X''\), i.e. \(J: X \rightarrow X''\), such that for all \(x \in X\), \(J(x) = J_x\) with \(J_x\) being defined as \(J_x(x') = x'(x) \; (\forall x'…

Virtual addresses from multiple address spaces are translated to real addresses in main memory by generating for each virtual address an address space identifier (AID) identifying its address space. Then, the virtual address and its AID are used to o…

最近做一个关于文档导出功能, 顺便学习了下freemarker,做了个关于导出带图片的word文档,模板并没有写全,只是验证代码的正确性 这只是做一个小功能,故只做了后台代码关于导出的代码,并未与前台关联,可酌情处理 首先将需要导出的word文档做处理,关于word文档最好是后缀为.doc,应为有些软件可能无法打开导出的文档,将需要修改的数据修改成${xxx} 类型的内容,例如下面的文档 修改后则变为如下类型: 后将文档另存为.xml文档,将需要修改的然后再打开xml文档,找到图片的位置,是一大…
