equation元素自始可用
A mathematical equation.
Can be displayed inline with text or as a separate block. An equation becomes block-level through the presence of whitespace after the opening dollar sign and whitespace before the closing dollar sign.
Example
#set text(font: "New Computer Modern")
Let $a$, $b$, and $c$ be the side
lengths of a right-angled triangle.
Then, we know that:
$ a^2 + b^2 = c^2 $
Prove by induction:
$ sum_(k=1)^n k = (n(n+1)) / 2 $
By default, block-level equations will not break across pages. This can be changed through show math.equation: set block(breakable: true).
Syntax
This function also has dedicated syntax: Write mathematical markup within dollar signs to create an equation. Starting and ending the equation with whitespace lifts it into a separate block that is centered horizontally. For more details about math syntax, see the main math page.
参数
block默认值：false
Whether the equation is displayed as a separate block.
numbering默认值：none
How to number block-level equations. Accepts a numbering pattern or function taking a single number.
展开示例
#set math.equation(numbering: "(1)")
We define:
$ phi.alt := (1 + sqrt(5)) / 2 $ <ratio>
With @ratio, we get:
$ F_n = floor(1 / sqrt(5) phi.alt^n) $
number-align默认值：end + horizon
The alignment of the equation numbering.
By default, the alignment is end + horizon. For the horizontal component, you can use right, left, or start and end of the text direction; for the vertical component, you can use top, horizon, or bottom.
展开示例
#set math.equation(numbering: "(1)", number-align: bottom)
We can calculate:
$ E &= sqrt(m_0^2 + p^2) \
&approx 125 "GeV" $
supplement默认值：auto
A supplement for the equation.
For references to equations, this is added before the referenced number.
If a function is specified, it is passed the referenced equation and should return content.
展开示例
#set math.equation(numbering: "(1)", supplement: [Eq.])
We define:
$ phi.alt := (1 + sqrt(5)) / 2 $ <ratio>
With @ratio, we get:
$ F_n = floor(1 / sqrt(5) phi.alt^n) $
alt默认值：none
An alternative description of the mathematical equation.
This should describe the full equation in natural language and will be made available to Assistive Technology. You can learn more in the Textual Representations section of the Accessibility Guide.
