Because credibility evaluation of large complex simulation systems involves lots of qualitative indices with multiple levels and granularities,hierarchical linguistic variables were used to acquire their evaluation information,and the two-tuple linguistic method was used to deal with the evaluation information with multiple sources and granularities,and the credibility quantificati.

The research on language level in object language and meta-language sense originates from the modern logic philosophy, and plays an extremely important role in the development of scientific theory of linguistics.

This paper aims to divide the equivalence theories in translation into three levels:language level,discourse level and culture level with special reference to its theoretical foundation——the interpretative theory of Paris School.

Ma Jian-zhong(马建忠) not only had the distinct view of hierarchical analysis, but also consciously used the hierarchical analysis to analyze the sentence.

He put forward the famous hierarchy theory of languages,created systematic semantics in modern sense,shew the extraordinary glamour of semantics to the world,and made widespread and profound influence on the scope of philosophy.
