 Your text area is too small. The paper seems to be downscaled.

 Via the link below, you can view your document with an added frame of the correct text-area size.

 Please note: The link was added to show the correct size.

 (The system complains only if the text is too large.)

 Such kind of shrinking is usually caused by post-processing procedures.

 Please avoid the post-processing.

use US letter instead of A4.

 

 

- Title: Please make sure to use the correct apostrophe. It should be unicode: U+2019.

 

Title中单引号要用：\texttt{'}

 

- Headings: 'Acknowledgments' should be a first-level heading without numbering.

\section*{Acknowledgment}

在排版中，寡行（widow）及孤行（orphan）是一段落开始或结束的一行在一栏的结束或开始处，不同资料定义的寡行和孤行有些不一致，可能某一资料定义的寡行，在另一资料中反而定义为孤行[1][2]。《芝加哥格式手册》的定义如下：

寡行

一段的最后一行在一页或一栏的开始处，和该段的其他行分开。

孤行

一段的第一行在一页或一栏的最后。

一段的最后一行只有一个字，一个字的一部分，或是最后一行的字母很少，因此和下一段之间看起来会有较多的空白。
