Through literature retrieval and literature reading analysis, this paper expounds whether the select

1) Save the resulting catalogue.

3) Browse the saved catalogue to get a preliminary understanding of the general direction and progress of the project.

4) Identify a few topics of interest or newer topics with potential, and then further verify the feasibility, and finally confirm the interests and prospects with your classmates, experienced brothers and sisters, mentors**, and finally confirm those who are interested and have development prospects.

2.After confirming the topic, that is, after narrowing down the scope, start from the new topic, search the literature in the original way, and try to search as much as possible.

1) Search in Chinese first, similar to the above, read the main reviews in detail, and then browse the found table of contents, and read the articles you are interested in or close to your own topic.

2) After searching in Chinese, start searching English literature, and you will feel much easier to read English literature when you have understood the domestic research trends. The main purpose of reading English literature is to further verify the authenticity of the articles written by domestic scholars, and on the other hand, to understand the recent developments. It would be best if you could find one or two reviews after reading the English literature, and foreign reviews generally have nearly 100 references, which are more credible and wider.

After reading the review, remember to also browse the English bibliography from the beginning, (it is recommended to use endnote software), beginners had better read each abstract in detail, and record the main content with notes, one to exercise the ability to read English, and the other to accumulate relevant literature background knowledge, in case of forgetting.

3) After reading a large number of domestic and foreign literature, summarize and write a review that is closely related to your own topic and prepare for publication. One can organize one's own thoughts, and the other can complete the task of publishing a review, killing two birds with one stone.

The literature doesn't say anything, how can others judge?

The research goal of the project is the final result of the research of the project, which is simply the specific purpose of the research and what kind of effect the research wants to achieve. For example, what kind of teaching model do you want to construct through research?

Teaching strategies, what new theories, new concepts, new perspectives, new understandings, etc. will be obtained. In the process of writing the research objectives, it is best to have a description of the level or degree to be achieved.

Topic proposal report.

Meaning and function.

The proposal report is a topic selection plan written by the person in charge of the project on the basis of investigation and research after the direction of the project is determined and submitted to the superior for approval. It mainly explains that the topic should be studied, that you have the conditions to conduct the research, and how you are going to carry out the research, and that it can also be said to be the demonstration and design of the topic. The proposal report is an important part of improving the quality and level of topic selection.

Periodicals – the fastest reflection of the latest results. Meetings - This feature is only available for some meetings. Reports – generally not specific enough.

Patents, standards – are new, but not the latest. Books are systematic and complete knowledge systems, but they can never be up-to-date.

The topics suitable for literature search are as follows:

The influence of soil environmental conditions on nitrogen fixation of leguminous plants", if it is not enough to only use the topic "soil environment", "leguminous plants" and "nitrogen fixation" as the subject words, we should do a more in-depth and detailed theme concept analysis of the topic, and select some words closely related to the topic content as the subject heading.

Determine the temperature, humidity and pH value of soil environmental conditions, soybeans and peanuts in leguminous plants, and nitrogen-fixing Plum Fungi and rhizobia that play an important role in nitrogen fixation, so that the basic content of the subject can be more fully revealed, and the possibility of seizing literature will be greatly increased.

For medical researchers, before conducting medical research, they often need to read a large number of relevant literature, because reading reference materials can not only enable medical researchers to have an in-depth understanding of some relevant knowledge of their specialty, understand the research frontier trends of their discipline, and provide reference materials, but also be familiar with the ideas and structures of other people's articles, experimental design, etc.

The literature search was conducted using the following methods:

1. Direct method. That is, the method of directly using the retrieval tool to retrieve literature information is a commonly used literature retrieval method, which can be divided into spot check method, forward check method and reverse check method.

2. Spot check method: according to the characteristics of the project, select the time period related to the literature information of the project that may appear or appear many times, and use the search tool to conduct key searches.

3. Follow-up method: a method of using the retrieval system to retrieve literature information from far to near in chronological order. This method allows for the collection of systematic literature on a certain discipline.

It is suitable for literature search on large topics. For example, if we know the year in which a research topic began, and now we need to understand the whole process of its development, then we can use the forward search method to start from the beginning and gradually work your way up to the present.

4. Reverse check method: The reverse check method is the opposite of the forward check method. The backward search method is from the new to the old, from the advance to the far, and the retrieval tool of reverse time is used to disturb the order of the literature.

The focus of this approach is on recently published articles. In general, this method allows for quick access to new information.

Literature search methodology.

The direct method, also known as the common method, refers to the method of directly using the retrieval system (tool) to retrieve literature information. It is further divided into the forward inspection method, the reverse inspection method and the spot check method.

The method of sequential search refers to the method of retrieving literature information by using the retrieval system from far and near in chronological order. This method can collect systematic literature on a topic, and it is suitable for literature retrieval on larger topics. For example, if you know the beginning age of a topic, and now you need to understand the whole process of its development, you can use the forward search method to start from the original era and gradually move to the recent era.

The backward search method is a method of using search tools to conduct literature search from near to far, from new to old, in reverse chronological order. The focus of this approach is on recent literature. This method is the fastest way to get the most up-to-date information.

Spot check methodSpot check method refers to the method of selecting the time period when the literature information about the project is most likely or occurring the most, and using the search tool to carry out a key search according to the characteristics of the project.

The traceability method refers to the method of tracing the original text (cited literature) one by one by using the references listed at the back of the document without using the general search system, and then expanding the scope of the literature information from the reference list listed after the original text, and tracing it one by one. It can snowball and obtain better search results based on the citation relationship between documents.

The round-robin method is also known as the segmented method or the synthesis method. It is a direct method and retrospective method alternately used in staging, in order to learn from each other's strengths and cooperate with each other to obtain better search results.

Answer: There are three main ways to search for literature: the first is the common method, which is a search method that uses reference books to find literature materials.

The second is the retrospective method, which is based on the literature attached to the available literature. The third is the round-robin method, which is also called the mixed method, which is a retrieval method that combines the retrospective method with the common method to find literature in a circular way.

There are several reading methods of literature, such as skimming, close reading, and intensive reading, each of which has its own characteristics and uses, and readers can choose reading methods flexibly and appropriately according to their own needs and the situation of the literature itself.

You're also a big deal? Wafangdian's?

There are many ways to search for literature, which you can describe in chronological order, which is related to the development of science and technology... The same is true for literature reading
