你看看是不是这种格式在网上，PDF几乎已成一种通用的文件格式，许多知名网站供网友下载申请表格和文档都选用了PTF（比如托福网站上的模试题）。PTF的中文译名是“便携式文档格式（Portable Document Format)”，这个文件格式的一大特点是可以在文档中内嵌字体，并忠实地保留文档原貌，因而可以跨越不同的操作系统和语言平台，版面格式也是整齐划一，不会像Word文档那样因为版本的不同而格式各异。打开、查看PTF的程序，大家熟悉的是免费软件Acrobat Reader，其实它只是Acrobat软件的一个部分-正版的Acrobat还包括了Acrobat Distiller、Acrobat Catalog和PDF Maker等。英文版的Acrobat4.0支持双字节的中文汉字，不过在安装时你要选择“Custom”安装并在“安装组件”中选中“Asian Language（亚洲语言）”
