There can be n thesis topics under a thesis topic, just like a sub topic under a topic.

The title of a paper is a very important part of the paper. Although the title is a relatively short part of the paper, it plays a very important role. Because when reading an article, everyone will look at the topic. Some readers will decide whether to read the article or not according to the meaning of the title.

1、 So what are the principles of the thesis title?

1. Accurately reflect the content of the paper, in line with its depth and breadth: the content of the paper includes introduction, materials and methods, results and discussion. However, the title of a paper can not reflect so much content, but only the main research object, method, purpose or result.

2. Describe the research results objectively and implicitly: the results of a paper are important, and the sublimation from the results to the conclusions is more valuable. In the title, the results and conclusions are not specifically mentioned, but are described objectively and implicitly. It is often described in terms of value, meaning, influence and observation.

3. Concise and eye-catching: to determine the title of a paper, we should also strive to be concise and eye-catching. The so-called conciseness means that the words are concise and easy to understand. For general Chinese titles, it is appropriate to use no more than 20 Chinese characters; however, there is no uniform rule on the number of words in English titles. Some magazines stipulate that 14-15 words or 84 printed symbols, or no more than two characters are appropriate. Generally, there is no subtitle, but in the case that it is impossible to be short, in order to supplement the content of the main title or to emphasize a certain key point, it can be considered to add a subtitle. The so-called "eye-catching" refers to that it can attract readers' interest.

4. Correct use of words: the title of a paper is composed of carefully chosen words, usually only a phrase, phrase or a complete sentence. When determining the title, we should pay attention to the proper use of words, use the correct professional terms, and try to be as fluent and easy to understand as possible, and avoid the use of vague and gorgeous words. In addition, it should be noted that there is no punctuation in the title. Chinese characters are used for numbers below 10 and Arabic numerals are used for numbers above 10. For example, in English titles, articles are often omitted. Except the first letter of the first word or proper noun is capitalized, the others are lower case. Except for function words, the first letter of each word is capitalized.
