答案1
article和LaTeX 文档类report默认使用oneside页面布局选项。该选项的一个特点是左右边距默认相等。
相比之下，bookLaTeX 文档类使用该twoside选项。其特点之一是，如果文档被打印并装订成一本实体书，则“内”边距（靠近书脊的部分）最终会比外边距更窄。有人曾告诉我，这是因为当人们在手中打开一本书时，他们通常会用拇指来操作。为了不让拇指遮住书写的文字，外边距（通常放置拇指的地方）通常会做得更宽一些。不过，我不知道这是否是真正的原因。
如果您需要使用book文档类但不喜欢twoside布局选项，请oneside明确指定：
\documentclass[12pt,oneside]{book}
