Conclusion should be accurate, complete, clear and concise. The writing content of this part should generally include the following aspects: ① What problems do the results of this study explain; ② What amendments, supplements, developments, confirmations or denials have been made to the previous viewpoints? (3) The shortcomings or unsolved problems of this paper, and the possible key points and directions to solve these problems.
The writing requirements of the conclusion part are: strict wording, strict logic and specific words, which are often listed as articles in the order of 1, 2, 3, etc. There is only one explanation, and there is no ambiguity or ambiguity. Don't exaggerate the text, there is room for attention to the content that is not completely determined.

Thesis title: Control of polymer composition in the oligomerization of butadiene and acrylonitrile.
The conclusion of this paper is:
1. For the batch polymerization system of butadiene and acrylonitrile with hydrogen peroxide as initiator and ethanol as solvent, it is necessary to control the composition to improve the performance of NBR due to the different polymerization rates of monomers.
2. In this work, the monomer composition and polymer composition of the reaction solution can be controlled by adding rapidly consumed monomers into the reaction system.
3. Based on the theory of free radical polymerization, a new calculation method of monomer addition is proposed. The experiment shows that the liquid NBR polymer with uniform composition ratio can be synthesized by this calculation method. This method can be used not only for the synthesis of butyronitrile hydroxyl, but also for other radical binary polymerization reactions.
4. The NBR synthesized by this method is not only uniform in composition, but also uniform in sequence release, and the distribution probability of sequence length 1 is as high as 97%.

Finally, it is pointed out that some academic papers, such as medical papers, are often? Quot The conclusion part is not listed separately, but its content is implied in the text of the discussion part (often in the last part, which is also the shortest text part), which is also a feasible treatment method. For example, there is a natural paragraph at the end of the paper entitled "Clinical significance of measuring the concentration of 25- hydroxyvitamin D3 in blood by competitive protein binding method": This study shows that CPBA method is not only a simple method, but also a sensitive and reliable indicator for observing the deficiency and excess of vitamin D in the body. In fact, this is the conclusion of the full text, and it is a general concept obtained from all the materials in the text through logical thinking processes such as reasoning, judgment and induction.
