Stylistic Features of EST
1
.About the English of Science and Technology
The English of science and technology (EST) is actually a big variety. It includes the English of chemistry, the English of physics, the English of mathematics, the English of biology, the English of medicine, etc.

But, generally speaking, the English of all scientific fields have something in common and on which we base our studies.
Of all the scientific fields, we usually subdivide them into two main varieties: the English of specialized science and technology (ESST), and the English of common science and technology (ECST)

EST is used in scientific works, academic thesis, research papers, experimental reports, the description or explanation of natural phenomena. In one word it is a variety of English, dealing with the theories and applications of science and technology.

This kind of writing is usually formal in style and serious in tone .It does not take artistic beauty of language as its goal, instead, it tries to achieve clarity in logic and accuracy in meaning. It ties to avoid subjective opinions or evaluations, ambiguous word or expressions.
5
It tends to employ words with the development of science and technology. The sentences are usually long and complete and subordinate appositive（同位语的） and parenthetical（插入语的） clauses are often used. Logical connectors, such as hence, in summary, as a result, appear in EST more frequently than in other types of writing.
