This paper has discussed the description method of coding block and used examples to explain different meaning s code.

The Research and Development of the Information Coding System Based on Web;

Method of production information coding based-character;

Military Material Information Coding System and Model Establishment

Information Encoding and the Object-Oriented Information Code Model;

Making the information encoding requires to study and analyse the use of the international norms,the national norms,the trade norms and the enterprise norms,which are related to the encoding objects,in the light of the needs of the enteprise information management system.

It analyzes its usages of mechanism and the effects of Man s cognitive on the generation of existential sentences in English and Chinese from the point of the Man s perception and information encoding.

Recognition of Measuring Instrument Information Code Based on BP Neural Network;

By analyzing the needs and work flow of enterprises,the paper presents designing scheme of database system,and sets forth logical structure,physical structure and equipment scheme of the database system,and gives the rules about data information code designing.

Message coding is very critical in product data management (PDM), which is the base of enterprise successfully applying PDM or CIMS.

Two laws on coding information quantity are discussed.

The first law is the universal growing of coding information quantity in a genome in the molecular evolution.
