文件正文

Laboratory reflectance spectra of differentiated meteorites can be used
to identify indicate the rock-forming materials of asteroids at small
scales \cite{Gaffey} and \cite{Trigo-Rodríguez1}.
Over the years, more information such as physico-chemical
properties of asteroids and their reflective behavior were obtained
by much sensitive and precise spectrometers \cite{Dotto} and  \cite{Trigo-Rodríguez2}. \\

Answer 1

文件中的引用/条目键.bib不应包含非 ASCII 字符（例如，í如果您使用非 Unicode 引擎）。原因是这些键用作内部标识符，因此 LaTeX 必须能够处理它们，而不会轻易破坏它们。

改变Trigo-Rodríguez1并Trigo-Rodríguez2​

Trigo-Rodriguez1

和

Trigo-Rodriguez2

í分别将和文件i中的键替换为。.bib.tex
