Extension:Math/zh

数学扩展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擴展和數學字體. 无障碍支持由NVDA、VoiceOver或Orca提供.  而且，NVDA需要MathPlayer来读出公式.
 * 对于Safari或者其他WebKit浏览器，你可能也需要安装数学字体并通过向浏览器参数设置的自定义样式表安装一些CSS规则启用本地MathML渲染.

无障碍支持由VoiceOver屏幕朗读器提供，但是还没有Orca.


 * 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. 对于你遇到的任何问题，最好的办法是在https://phabricator.wikimedia.org创建一个任务.

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.

此外，GitHub上有个通过Restbase和MW 1.28的Mathoid安装并设置MediaWiki的教程.

数学输出模式
设置$wgMathValidModes包含含有可以用于渲染的输出模式的名称的序列. 如果多个模式启用，已登录的用户可以在用户参数设置页面的appearance面板中设置个人偏好.

你也可以使用$wgDefaultUserOptions设置来设置哪个模式是默认的，比如：

Mathoid
模式： 'mathml'

You can use Mathoid, an application that uses MathJax on the server side to convert texvc input to MathML+SVG rendering. This is the most recommended option; Mathoid is the Math rendering mode used on Wikipedia.

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：

Mathoid的命令行接口
You can instead run Mathoid as a command-line utility on the local server. This option is possibly easier to set up and will result in less permanent memory consumption. However, performance will probably be lower. To use this approach, the following settings are recommended:

LaTeX
模式： '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'

Uses the LaTeXML utility. The rendering is done via an online service (set with $wgLaTeXMLUrl, which has a default value of https://latexml.formulasearchengine.com/convert).

未渲染
模式： '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.

跟踪分类
扩展会创建一系列跟踪分类，以检测错误和不被推荐的特性. 分类的准确名称由MediaWiki名字空间内的页面决定.

提示与技巧
To force the re-rendering of all formulas of a page, purge using the  action. For example the URL https://en.wikipedia.org/w/index.php?title=Integral&action=purge&mathpurge=true will force re-rendering of the Integer article. Afterwards you need to bypass your browser cache so that the new created images of the formulas are actually downloaded.
 * 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  attribute to the  element. e.g. to force an image being rendered.
 * All images of rendered formula are stored in a cache and not automatically recreated if the page is viewed or edited.

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.
