摘　　要：采用合适的底物可以使寡肽的ＦＡＢ质谱图同时提供有关肽的分子量和氨基酸的信息。发现了经验公式Ｂ＋Ｙ＝Ｍ＋２，根据这一公式可以方便地推导出肽的氨基酸序列。FAB mass spectra of sereral synthetic oligopeptides were improved by using various matrices. They provide imformation of both molecular weights and the sequence of amino acids in oligopeptides.An empirical formula B_n+Y_n=M+ 2 was found.From B or Y ion series,the sequence of amino acids in oligopeptides could be induced.
