Extension:Math/zh

数学扩展端提供渲染数学公式的支持. 有关当前此扩展的功能的概述，请参考这个英语维基百科页面.

更多有关安装和配置此扩展（包括旧版本）的信息，可在中查阅.

查看数学公式
数学扩展会依次尝试输出MathML、SVG图片（将字符转换成&lt;路径>）或PNG图片（最低优先级）. 输出的结果将取决于你使用的设备的兼容性. 基本數學支持適用於所有瀏覽器. 但是，為了獲得最佳渲染，可能需要進行特定的調整：


 * 對於Firefox或其他Gecko瀏覽器，需要安裝Native MathML擴展名和數學字體. Accessibility support is provided by NVDA, VoiceOver or Orca. Additionally, NVDA requires the MathPlayer plugin to read mathematics.
 * For Safari or other WebKit browsers, you may also install math fonts and enable native MathML rendering by inserting some CSS rules into the custom style sheet of your browser preference.

Accessibility support is provided by the VoiceOver screen reader but not by Orca yet.


 * For Chrome you must insert some CSS rules into the custom style sheet of your browser preference in order to get accessibility support via ChromeVox or visual rendering via the MathJax plugin.
 * 在一些版本的Internet Explorer中，可以使用MathPlayer作为一种辅助科技.

安装
You should additionally go to the page Special:MathStatus to see whether all of the components of the Math extension now work. For any problems you see, the best option is to create a task on https://phabricator.wikimedia.org

Unfortunately, there is no well tested guide on installing and  to work with the Math extension, but there is at least a working draft. 请贡献.

In addition, there is a Guide for Installing and Setting up Mediawiki with Restbase and Mathoid in MW1.28.

数学输出模式
The setting $wgMathValidModes holds an array with the names of output modes that can be used for rendering. If multiple modes are enabled, logged-in users can set a personal preference in the appearance pane of their user preferences page.

You can also use the $wgDefaultUserOptions setting to set which of these modes should be the default, e.g.:

Mathoid
模式： 'mathml' (pre-July 2015: MW_MATH_MATHML)

For MW 1.23 and higher, you can use a Mathoid server that uses MathJax to convert texvc input on the server side to MathML+SVG rendering. This is the most recommended option; Mathoid is the rendering mode that will be used on Wikipedia in the future.

服务器上的Mathoid
为了使用服务器上的Mathoid以获得表现形式上的好处,推荐进行下列设置：

关于自行搭建Mathoid服务器的指南在Mathoid页面 Note that as of March 2017 this is likely to also require a server/installation (see ).

Mathoid的命令行接口
To use Mathoid's CLI interface, which is possibly easier to set up and resulting in less permanent memory consumption, while degrading performance, the following settings are recommended:

LaTeX
模式： 'png' (pre-July 2015: MW_MATH_PNG)

Since MediaWiki 1.32, this mode will also require a Mathoid server to work. In older versions, it requires installing texvc and texvccheck, which may require the most setup work.

LaTeXML
模式： 'latexml' (pre-July 2015: MW_MATH_LATEXML)

Uses the LaTeXML utility. The rendering is done via an online service (set with $wgLaTeXMLUrl, which has a default value).

未渲染
Mode: 'source', (pre-July 2015: MW_MATH_SOURCE)

This mode will forward the Latex input without rendering, presenting it in a element, surrounded by $ :formula $.

Make sure to set $wgMathDisableTexFilter to 'always' (see below) if you only want the raw latex formula, else an error will appear due to the failed check for PNG depictions.

Tracking categories
The extension creates a number of tracking categories to detect errors and deprecate features. The exact name of the categories is determined by pages in the MediaWiki namespace.

提示与技巧

 * You can use the Firefox MathML copy addon to copy formulae to other applications such as Microsoft Word (video), or Google docs with the g(Math) plugin (video)
 * You can override the user preferred and default rendermode by adding the  attirbute to the $$ element. eg.. to force an image being rendered ...$$.

错误报告
If something is wrong with the math extension you can report that at Phabricator. In addition you should check how your problem relates to the automated unit tests that are generated from the page CoverageTest.
