Abstract: First,from the viewpoint of the present information society,the authors give a new definition to CCC,which is a second form of Chinese Characters.The application of CCC is not limited to the computer technology only,but also extends to many other areas,such as compiling a dictionary,sending a telegraph or telex and compiling indexes on cards or books.Therefore,it is required that CCC must be unified and most widely adaptable,just as it is with Chinese characters,which is also a most important criterion in evaluating a CCC scheme.The design of a CCC scheme should be mainly based on Chinese character's shape code which reflects the inherent meanings of Chinese characters.And the shape code depends on the components of Chinese characters.Hence,the study of the structural law of a Chinese character's shape is the foundation for processing a Chinese character model.Components are the letters of a Chinese character.According to the strict definition of components,the authors have divided the whole of Chinese characters into nearly 400 components,and on the basis of their definite features,classified the components into 2 series,5 types,13 forms and 49 categories,thus establishing a systematic and coherent classification system for Chinese character components.This system could also be used as an important means for those who learn to read Chinese characters.On the foundation of the classification system of natural components,and through composing and decomposing,the 49 categories of components are arranged on the 31 keys of a standard computer by applying the laws of Latin alphabet and numerals.These components are called"coding components",because they are sorted,named and put in order.The"bottleneck",i.e.the difficulties in CCC is thus broken through.In this paper,the authors present in detail the"symbols for shape-representation of of Chinese characters"and a series of CCC schemes——computer code,pure shape code,pronunciation code which can distinguish homonyms,dictionary code,telegraph code and the Chinese characters in Japanese and Korean.This CCC scheme is as well suitable for both simplified forms and original complex forms of Chinese characters.This method which uses only one kind of basic symbols(or code names)enables the CCC to reach a high level of unity.
