摘　　要：用毛细管气相色谱法对一些汽油样品组分进行了分离。在得到的色谱图上 ,选取合适的色谱峰对 ,用峰高比或峰面积比求出色谱峰对的斜率参数 ,采用极坐标法对这些参数作图 ,便得到该油品的星状图 ,用星状图法对一些商品汽油的油源成功地进行了比对鉴定 ,结果满意。A method of the comparing identification of gasoline resources by using star-shaped graphs has been established. On each chromatograph, the proper pair of fingerprint peaks were selected and the slop parameters were obtained. The star-shaped graphs were drawn by means of polar coordination. Comparing the star-shaped graphs of unknown gasoline resources with those of some commercial gasoline, we can judge where the unknown gasoline is from. The results are rather satisfactory.
