摘　　要：随着LAMOST光谱巡天项目的不断推进,积累的光谱数量已经步入千万量级。因科学研究需求或大量低信噪比光谱的不断产出,在光谱处理过程中,常涉及大量的人工识谱任务。为了方便用户高效便捷地进行人工识谱,基于MATLAB设计并实现了一套一维光谱可视化与分析工具。该工具包括谱线标识、滤波去噪、红移测量、等值宽度估算等功能。该工具操作简单、直观,在特殊天体搜寻、LAMOST"UNKONWN"光谱的人工处理等方面具有较高的使用价值。With the development of LAMOST spectroscopic Sky Survey project,the accumulated spectra in the world have stepped into tens of millions of magnitudes.Due to the need of scientific research or the continuous output of a large number of low signal-to-noise ratio spectra,a large number of manual spectral identification tasks are often involved in spectral processing.In order to facilitate users to carry out manual spectrum recognition efficiently and conveniently,this paper designs and implements a one-dimensional spectral visualization and analysis tool based on MATLAB programming technology.The tool includes spectral line identification,filtering and denoising,redshift measurement,and equivalent width estimation.The tool is simple,intuitive in operation.It has high application value in the search of special celestial objects and the artificial processing of LAMOST"UNKONWN"spectra.
