1. From the content point of view, scientific language shows the nature, attributes and characteristics of objective things. Scientific language is only to convey information and strive for an objective and scientific statement. The language of literature expresses the author's subjective feelings, thoughts and values, focusing on expressing emotions. For example, Li Bai's poem "Snowflakes in Yanshan Mountain are as big as seats" is obviously absurd from the perspective of scientific expression, but Li Bai's main purpose is to convey a feeling of surprise in the face of heavy snow in the north, not to show the facts.
2. From the perspective of expression, scientific language emphasizes accuracy and conforms to grammatical norms, while literary language is vague, which can break grammatical norms and human habits. Scientific statements need strict logic and authenticity. The scientific statement is true because it conforms to objective facts. However, literary statements are illogical and illogical in nature. Even if there is logical reasoning, it is subordinate to emotional meaning to stimulate emotional attitude.
3. From the perspective of language structure, the language of science and technology requires to convey information in a concise and clear way, so the language it uses is mostly stylized. Scientific works and administrative documents are stylized not only in format, but also in language. Such as "in summary", "the reason is as follows", "approval" and "hereby notify" are mostly technical terms. The language of literature focuses on innovation and breakthrough, and pursues individuality and novelty. Many literary works, especially poems, often have sentence patterns that do not conform to grammatical norms. For example, Du Fu's "fragrant rice pecks at parrot grains, and the old phoenix perches on green trees" uses a special sentence pattern of prepositional object in order to express special feelings and render a specific atmosphere.
In a word, the language of science is rational, normative and logical, while the language of literature is perceptual, personalized and visual.
