FingerPrints Quality Evaluation System

FingerpPrints mean that the diagrams got by methods such as spectrum or chromatogram etc. measurement divides the characteristic diagrams or pictures of the components .We can get the characteristic diagrams of the components or images by some particular methods , these chromatograms are similar to the human fingerprint ,they are unique and representative, so we calls it as the fingerprints .Currently the fingerprinting technique have already be used for the quality evaluation extensively, by the comparabilities and relativities contrast, we can find out the quality variation and limitation ,and the manufacture process of the Chinese herbal medicine keep consistency.Along with the development of the society and the progress of sciences, the computers have got the unprecedented application in the each traditional academic field, various developments of related software have brought a kind of upsurge. The quantity evaluation system of the fingerprints that this thesis study exactly according to the advanced C# language, combining the SQL Server 2000 database, to provide for the spacious science workers a quality evaluation system what is more convenient, normative, be easy to operate .The system is the Sichuan province fund development item, so regardless a research or an application, have the important meaningThe chemistry information center(CIC) of Sichuan university is establishing a chemical remote computation platform based on cluster and web, and our platform is commonly shared and exoteric, the customer can visit the Web site conveniently and choose our calculation service but be free from the restrict of the customeroperate system .And the platform is established by three layer structure ,it is steady and efficient, this will become the fast chemistry calculation method and have the unique and profound meanings.Above the all, we can get the main research result of this thesis :1. By the study of related knowledge, analyzed the application of the fingerprints technique in quantity evaluation, established the fingerprints quality evaluation system with the form of the software.2. Elaborated the design of the system's software, and carried out manifestation of the chromatogram and its some simple treatment .studied the the theories of the peak computation at the same time.3. Studied a calculation method of comparability detailedly, adopt to clip the angle cosine calculate way and get the realization through Matlab.4. Combined the chemical remote computation platform based on cluster and web,, eased to the chemometrics worker's labor very effectively, come to a innovation of the system.
