形如

//pages\en-abstract-page.typ
#import "../fonts/font-def.typ": *

#let en_abstract_page(abstract, keywords: ()) = {
  set heading(level: 1, numbering: none)
  show <_en_abstract_>: {
    align(center)[
      #text(font: heiti, size: 18pt, "Abstract")
    ]
  }
  [= Abstract <_en_abstract_>]

  set text(font: songti, size: 12pt)

  abstract
  par(first-line-indent: 0em)[
    #text(weight: "bold", font: heiti, size: 12pt)[Key Words: ]
    #text(font: heiti, size: 12pt)[#keywords.join(", ")]
  ]
}
