Bibtex 编写的参考书目中第一个条目 [1] 为空白

Bibtex 编写的参考书目中第一个条目 [1] 为空白

我的问题如标题所示。第一个条目是我的参考书目完全是空的/空白的,显然,我的文件中没有空项bibtex

(这是我想展示问题的屏幕截图的地方,并且我不允许发布超过 2 个链接...)

我对使用 LaTeX 还很陌生,我不知道排除故障需要什么信息,所以请直接提问。

我正在使用 TeXStudio,以下是我的主文件中的包。

\documentclass[a4paper,12pt]{book}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage[space]{grffile}
\usepackage{amsmath} 
\newcommand{\angstrom}{\textup{\AA}}

\usepackage{float}
\usepackage{wrapfig}
\usepackage{subfig}
\usepackage{mathrsfs}
\usepackage{wrapfig}
\usepackage{hyperref}
\usepackage{url}
\setcounter{secnumdepth}{3}

我要继续链接我的主文件比博特文件,因为它们太长,无法在此打印。

谢谢!

答案1

嗯,你的 bib 文件中缺少一些逗号。它们导致你的第一个条目为空。

请检查以下 bib 条目是否缺少逗号:

@article{cyclotron,
@article{Schmidt2005,
@article{inversebrems,
