Symmetry principle in scientific text

The dynamic changes of science text structure are observed in the article. The material for the research is a science article. About 100 texts were investigated. The symmetry among texts is presented by varied repetitions: identical words, pronouns, semantical. We have discovered the following forms of symmetry: the golden section, mirror symmetry, transport symmetry, and homology. The two forms of symmetry among texts are determined: proportional (standard composition) and transport symmetry (lexical). The amount of symmetry in a text declines while the amount of symmetry among texts rises. The research revealed the growing trend towards standardization of the form of scientific text. In the modern scientific article structure, the role of composite elements is increasing. The standardization of structure compensates the reduction of reliability caused by reduction of the number of repetitions, facilitates perception and accelerates evaluation of significance of the scientific article content for a recipient.
