1. Objectivity: When writing an abstract of a paper, it needs to be consistent with the content of the paper, not exaggerated or reduced, and it also needs to be summarized around the viewpoints and methods of the content.

2. Concise: The abstract of the paper is the concentration of the content of the paper, and there is a word limit, generally no more than 400 words. Summarize the content in relatively concise language.

3. Integrity: This is not only the condensed content of the paper, but also an independent essay, which needs semantic coherence, smooth logical relationship with the context of the paper and rigorous structure.

Example: the influence of price promotion on brand equity.

Abstract: As an important part of marketing mix, price promotion will inevitably have a far-reaching impact on brand equity.

On the basis of consulting a large number of documents, this paper analyzes the influence of price promotion on brand rights and interests.

At the same time, it also summarizes the research conclusions of domestic and foreign scholars on the influence of price promotion on brand equity under the influence of different regulatory factors, and puts forward the future research direction.

For example: the influence of celestial bodies on the acceleration of gravity of the earth.

Abstract: The acceleration of the earth's gravity is an extremely important physical quantity. With the improvement of the accuracy of gravity acceleration measurement, the influence of celestial bodies on the earth's gravity acceleration must be considered.

In this paper, the basic concept of the influence of celestial bodies on the gravity acceleration of the earth is introduced, and the calculation formula of the influence is derived. Through error analysis, it is proved that the relative error of this formula is less than 1× 10-9, which can fully meet the requirements of modern precision gravity acceleration measurement.
