latex学习 day3 elsarticle.cls学习

elsarticle.cls要用到的一些包

• natbib.sty 处理引用 for citation processing，处理各种各样的引用，和hyperref.sty，hypernat.sty一起完美工作
• geometry.sty 页边距设置 for margin settings
• fleqn.clo 左对齐公式 for left aligned equations
• graphicx.sty 加入图像 for graphics inclusion
• txfonts.sty 其他字体，可选的包optional font package, if the document is to be formatted with Times and compatible math fonts
• hyperref.sty 如果文章要使用超链接，则需要这个包optional packages if hyperlinking is required in the document
• endfloat.sty 把所有floats（图,表等）放在文末则需要用 optional packages if floats to be placed at end of the PDF.
• ams的数学包比如 amsmath.sty, amsthm.sty, amssymb.sty, amsfonts.sty都是免费随便用的，developed by
  the American Mathematical Society美国数学协会开发的
• hypernat.sty
• graphicx.sty, is part of any standard LATEX distribution, is loaded by default.
• multirow.sty, array.sty做表格的，进一步增强和调整表格，需要自己load（\usepackage{}）

关于图像格式：
LATEX accepts figures in the postscript format ，比如eps
while pdfLATEX accepts *.pdf, *.mps (metapost), *.jpg and *.png formats. pdfLATEX does not accept graphic files in the postscript format.

elsarticle.cls is built upon article.cls ，基于article.clc的，所以All options of article.cls can be used with this document class。

preprint and final formats的区别

• preprint document formatting（默认）：default option which format the document for submission to
  Elsevier journals

preprint是提交给期刊审核用的，默认单栏，文本宽度384pt. When you use elsarticle.cls for formatting your submissions in the preprint mode, the document is formatted in single column style with a text width of 384pt or 5.3in.

• formats the document as per the final style of models 1+, 3+ and 5+ of Elsevier journals

final print是出版的最终版，如果期刊是双栏的就要改格式，容易遇到公式断裂的现象。 When this document is formatted for final print and if the journal happens to be a double column journal, the text width will be reduced to 224pt at for 3+ double column and 5+ journals respectively.

最终版主要是要注意对应期刊的纸张尺寸和页面边距format their submission to the page size and margins of their preferred journal

TEX needs two compilations to resolve the footnote marks in the preamble part

好神奇！！！竟然需要编译两次，亲自尝试，如果只编译一次，email address和url就不出来，这就是因为脚注还没解析好，牛逼

用elsarticle.ins生成elsarticle.cls

elsarticle.ins is the LATEX installer file安装文件，用latex编译它就可以得到cls文件（类文件，class文件）
先打开elsarticle所在路径，然后调用latex命令，结果太长我不粘了，但是cls文件确实成功生成了

然后把生成的cls文件复制到D:\texlive\texmf-local\tex\latex\elsevier路径，也可以放在别的latex编译时可以搜索到的路径下
然后更新latex的文件数据库，用texlive发行版texhash命令，miktex发行版好像是用mktexlsr

用enumerate改变列表list的计数器counter和属性

\begin{enumerate}[1.]
	\item The enumerate environment starts with an optional
	argument ‘1.’, so that the item counter will be suffixed
	by a period.
	\item You can use ‘a)’ for alphabetical counter and ’(i)’ for
	roman counter.
	\begin{enumerate}[a)]
		\item Another level of list with alphabetical counter.
		\item One more item before we start another.
		\begin{enumerate}[(i)]
			\item This item has roman numeral counter.
			\item Another one before we close the third level.
			\end{enumerate}
		\item Third item in second level.
	\end{enumerate}
	\item All list items conclude with this step.
\end{enumerate}
\begin{enumerate}[Step 1.]
	\item This is the first step of the example list.
	\item Obviously this is the second step.
	\item The final step to wind up this example.
\end{enumerate}

上图的negative space用于减小距离

The \quad and \qquad commands are often used to adjust aligned formulas or to add space before text in a math formula. The size of \quad (= 1 em) and \qquad (= 2 em) depends on the current font.

18 mu = 1 em

\mspace{3mu} adds a space that is 1/6 em long.

The \, and \! commands are the most useful for fine tuning math formulas,

一些示例

$\sin(x)/\!\log(x)$  \\ %用\!减小距离
$\sqrt{5}\,\text{side}$\\ % \,拉开距离
$\int_{0}^{\pi}\sin x dx=2$\\
$\int_{0}^{\pi}\sin x \, dx=2$\\
$f(1/\sqrt{n})$\\
$f(1/\sqrt{n}\,)$\\
$f: A \to B$\\
$f \colon A \to B$\\ %\colon的spacing效果比:好
$|-f(x)|$\\  %这样写的话，spacing不对
$\left|-f(x)\right|$\\  % 要用\left|和\right|

\phantom{-}1 & \phantom{-}3 & \phantom{-}1\\
\phantom{-}2 & \phantom{-}1 & \phantom{-}1\\
-2 & \phantom{-}2 & -1\\

\begin{align*}
a + b + c & + d \phantom{ {}+e } = 0,\\
c & + d + e = 5.
