在利用文献调查法的过程中，由于受到条件的限制，本文的研究还存在很多方面

In the process of using the literature survey method, the research of this article still has many deficiencies due to the restriction of conditions. First of all, it is increasingly difficult to search for documents. Because of the continuous development and improvement of information technology and network technology, information knowledge is growing rapidly, and the number of carriers and documents storing knowledge content is also rapidly increasing. Although the increase in the number of documents and the rich channels of information sources provide researchers with multiple choices, it is actually very difficult to find systematic and high-quality information in the vast ocean of documents.

In the process of using literature investigation method, due to the limitation of conditions, there are still many shortcomings in the research of this paper. First of all, the search for literature is becoming more and more difficult, because information technology and network technology are constantly developing and perfecting, information knowledge is growing rapidly, and the number of carriers and documents storing knowledge content is also increasing rapidly. Although the increase in the number of documents and the rich sources of information provide researchers with a variety of options, it is very difficult to find systematic, high-quality information in the vast ocean of literature.
