The model of Minjiang River woodland expert classification was established by analyzing the rule of the spectral curve which was exeracted from the TM images with the help of the fifth forest resource continuous investigation data in the.

In this paper,the rule of hyperspectral curves of different types of wetland in Dongtinghu Lake were analyzed,a model of decision tree for the final classification was constructed by the Erdas Image expert classification,and vegetation classification supported by GIS data and phonological information was made by using 2-seasonal ETM data of Dongtinghu Lake wetland.

To improve remote sensing image classification accuracy,analysis is made on the mechanism of the traditional unsupervised classification,supervised classification and expert classification.

International patent classifications for nanotechnology were introduced respectively.

Automatic patent classification is of great importance.

In this paper, the background and research status of patent classification are introduced in detail, and the problem of patent classification is defined.

The dental professional first aid and care, triage of casualties, maxillofacial surgery, forensic odontology to the struggle for the mass casualty and disaster events were discussed.

This paper introduces a member classifying model which can be used to classify the members of the communities in different types.
