Abstract
According to the theory of prior using of new information,based on the research of already existed strengthening buffer operators, some new strengthening buffer operators are established. Meanwhile,their characters are studied. The flaw that the existing strengthening buffer operators can,t fully use new information of the data sequence is overcame. The problem that there are some contradictions between quantitative analysis and qualitative analysis in pretreatment for vibration data sequences is resolved effectively. An example simulation shows, compared with the existing strengthening buffer operators, the kind of new strengthening buffer operators increases the forecast precision of GM(1,1) remarkably.
