| Abstract: |
| In the context of processing the multimedia information accompanying with the historical events，a lot of events can be viewed as growth procedure．This paper gives a mathematical model for the growth phenomena，and discusses its additive property，monotonicity and stability．It also introduces the ignore_trivial algorithms and non—triv-ial increment algorithms in MHBase——the prototype of multimedia database system． |
| Key words: Temporal database,multimedia,growth procedure,ignore trivial algorithm,non trivial increment algorithm． |
