与国际同类工作比较,ASES/MS的质谱检索系统有两个特点:一是系统所依存的质谱数据库有更高的科学质量,在建库过程中,我们修改和抛弃了广泛流传于国际质谱数据资料中的约2000个化合物的错误质谱;二是采用独立发展的正反检结合型原理检索策略,较好地克服了国际上的单纯正检索或单纯反检索原理系统的缺陷,集中了两者的优点.
Compared with similar international work, there are two characteristics of ASES / MS mass spectrometry search system: First, the system-dependent mass spectrometry database has a higher scientific quality. During the process of building a database, we modify and discard the mass spectrometry data Data of about 2000 compounds of the error mass spectrometry; the second is the use of independent development of positive and negative check combined with the principle of search strategy to better overcome the international simplex or simple anti-retrieval system of the shortcomings of the principle of both The advantages.
