The accuracy of language expression in academic papers is based on objectivity and authenticity. In a narrow sense, it refers to the accuracy, objectivity and authenticity of language symbols such as words, units of measurement and formulas. In a broad sense, it means that the text language as a whole strives to be clear in concept, accurate in judgment, rigorous in logical reasoning, standardized in grammar and clear in conclusion, which is a true and objective expression of the aesthetic object. Therefore, it is required that language as a cultural carrier or as an aesthetic object can correctly reflect the nature of natural and social life. Language has its own characteristics and subjectivity, and the choice of its language object is also complex and arduous. The aesthetic subject can not only take a high position, take the whole situation into consideration, but also grasp the "one" that can best reflect the essence and essence of things and phenomena, grasp the "one" that can best portray lifelike things, and be good at grasping the essence through phenomena. This is not only the consideration of the thinking quality of the aesthetic subject, but also the verification of the text foundation of the aesthetic subject. The ability of choosing words and making sentences is not only from rich language accumulation, but also from the ability of elaboration. Every aesthetic subject should pursue the realm of "adding one word is too long, deleting one word is too short".
