摘要：

The big number of spectra collected nowadays by large spectroscopic surveys (such as LAMOST, APOGEE, RAVE, and others) requires software for automated analysis. I present the software SP_Ace, designed to derive stellar parameters and chemical abundances. I describe how it works and show its performance with application on real spectra such as the ELODIE spectral library and the LAMOST database, with which we recently performed the analysis of the LAMOST spectra of the first data release (DR1, paper submitted). I also discuss some key points that affect the accuracy of any method of spectroscopic analysis.
