In accordance with the characteristics of mass spectrum databases,many KDD algorithms,such as the new match and index algorithm of mass spectrum,and the Multi AdaBoost algorithm based on boosting native Bayesian learning as well as statistical ways, are adopted during data preprocessing,and the results make it possible for us to better understand mass spectrum databases.

A matching algorithm for library searching of mass spectrum;

Geomagnetic matching algorithm based on vector search;

Prediction-based resource matching algorithm;

COMP: an efficient multi-pattern/multi-object match algorithm;

RETE, which is applied to production systems, is so far considered as the match algorithm with the best performance.

This paper researches the spectrum survey,classification and matching arithmetic.

The simulation and analysis platform for gravity-aided underwater navigation is designed based on Simulink tool,and each model in the platform is introduced in detail from principium to process,thus a full gravity-aided simulation system with gravity data base,matching arithmetic and efficiency evaluating is built.
