信息中介是主客体相互转化的必要条件之一;信息中介是一复杂的系统,它依主客体相互转化的不同指向而有不同的排列组合,形成不同的结构;主客体之间的信息中介具有多道性、多级性,其中介区间又具有相对性。主体和客体的信息中介是在现实的实践一认识活动中建构起来的。文章对初始结构的划定、主客体通过信息中介相互选择、建构和转化的过程及其内在机制进行了初步的探讨。 Information intermediary is one of the necessary conditions for mutual conversion of subject and object. The information intermediary is a complex system which has different arrangement and combination according to the different directions of the conversion of the subject and the object and forms different structures. The information intermediary between the subject and the object has Multi-channel, multi-level, and its intermediary interval has relativity. The agent of the subject and the object is constructed in the practice of reality. The article makes a preliminary study of the delineation of the initial structure, the process of the construction and transformation of the subject and the object through the mutual selection, construction and transformation of information intermediaries and their internal mechanisms.
