在 Latex 中格式化关键词和摘要

Question

关键词和摘要没有正确对齐。

我正在使用 Latex 撰写期刊文章。请参阅所附的屏幕截图。我希望​​摘要和关键词具有相同的边距。我该如何调整缩进长度以使其与摘要对齐。谢谢。

\documentclass[letterpaper,11pt]{article}
\usepackage[sumlimits,]{amsmath}

\usepackage[margin=0.8in]{geometry}
\usepackage[utf8]{inputenc} % set input encoding (not needed with XeLaTeX)

\onehalfspacing


\setlength{\parindent}{0pt}
\setlength{\parskip}{0em}
\usepackage[hidelinks,bookmarks=true]{hyperref}
\usepackage[numbered]{bookmark}

\makeatletter
\newcommand*{\sectionbookmark}[1][]{%
  \bookmark[%
    level=section,%
    dest=\@currentHref,%
    #1%
  ]%
}
\makeatother

\usepackage{abstract}
\setlength{\absleftindent}{0.5in}
\setlength{\absrightindent}{0.5in}

\providecommand{\keywords}[1]
