The purpose and significance of computer graduation thesis research: the purpose and significance of research, that is, why to study and study its value. This can generally be based on the actual needs, pointing out that there is this problem in reality, which needs to be studied and solved, and what practical role the research of this topic has, and then writing out the theoretical and academic value of the topic. These should be written more specifically and pertinently, and we should not shout slogans aimlessly.

Don't write all the general slogans such as adhering to the educational policy, implementing quality education and improving the quality of education and teaching. The main contents include: the relevant background of the study: that is, what is the basis and enlightenment of this study. Through the analysis of local education and teaching practice, this paper points out why we should study this subject, the value of the study and the problems to be solved.

As a necessity of people's life, sugar has a history of 5,000 years. Humans first used honey as a sweetener. Since then, sugar has been made from corn and sugarcane with starch, but it has only been more than 200 years since beet was made. With the development of society, all walks of life need a large number of sugar products, thus promoting the development of starch sugar industry. Therefore, it is very meaningful to study the technological principle of starch sugar and reduce energy consumption and cost.

Research status of the subject. The latest achievements and trends of related research The sugar produced by starch is called starch sugar. There are many kinds of starch sugar products with a long history of production. In the deep processing of glucose, although it was discovered as early as 1897 that alkalinity can catalyze glucose isomerization and convert it into fructose, this alkaline isomerization reaction has been continuously studied in the future, but it still cannot be applied in industry. The main reasons are that the reaction is not easy to control, the conversion rate is low, and the sugar decomposition products are dark in color, poor in taste and difficult to refine.

From 65438 to 0957, Marshall et al. found that Paecilomyces pseudomonas can catalyze glucose isomerization and convert it into fructose, but the yield of this enzyme is low and the culture medium is expensive, so it can't be put into production. The research on high fructose corn syrup started a long time ago, but it has not been popularized yet. At present, the research institute of Northeast Pharmaceutical Factory is taking the time to study the production technology of high fructose corn syrup, which is expected to be put into production and put on the market in recent years.

The research content, research methods to be adopted, technical routes and research difficulties, and the expected goal of the project are to explore the process principle, study the important control points in each process, and analyze the methods to effectively reduce energy consumption with starch-containing grains and potatoes as raw materials and sugar prepared by acid method, acid enzyme method or enzyme method as raw materials. The difficulty of this experiment is to find out the key control points in each process.

Wuthering Heights is regarded as the most peculiar novel, and it has become a pearl in the history of English literature in the 109 century. Heathcliff, the protagonist in emily bronte's novels, attracts many readers with his unique personality and pursuit of love. The purpose of the topic is to analyze Heathcliff's personality from the perspective of Freudian psychoanalysis, and put forward the fierce conflict between Heathcliff's inner id, ego and superego, as well as his complex psychological state and the transformation process from love to hate.

By studying the distorted human nature and complex mentality in the crazy and complicated real society, this paper shows Heathcliff's distorted personality and explains the social roots of the cracks in human nature in the distorted society. By describing the love between Heathcliff and Catherine, it shows that Heathcliff, the protagonist, distorts human nature in a deformed society, and then becomes tyrannical and heartless, resulting in a strong revenge mentality. After achieving the goal of revenge, he ended up committing suicide, which reached a shocking artistic power with violent emotions.

This paper further discusses the dual personality of the protagonist in the process of revenge, and then puts forward my own profound understanding of this work, trying to explore the practical significance of human nature and showing the great artistic charm embodied in Wuthering Heights' profound psychological description of the characters.
