References Literature, what is the difference? What is the difference between historical and documen

Sources and literature are two different concepts.

Materials refer to various resources that can be used to obtain information or conduct research, including books, newspapers, magazines, periodicals, electronic literature, library materials, archival materials, experimental data, etc. In academic research, researchers need to collect and use a wide range of materials to obtain knowledge and information in related fields and support their own research work.

Literature refers to academic works or works such as books, reports, articles, speeches, etc., which have been published or published. In academic research, researchers need to read and cite literature in related fields to support their own research work, and at the same time, they also need to publish their research results as academic literature for other researchers to refer to and cite them.

Therefore, although there is a certain overlap and overlap between information and literature, the main difference is that the former is a broad resource**, while the latter is a published or published work or work of an academic nature. In academic research, researchers need to pay attention to and make use of both in order to obtain adequate information and support.

Literature is a carrier that records human knowledge by technical means such as words, graphics, symbols, audio frequency, and **, or is understood as knowledge solidified on a certain material carrier. It can also be understood as a general term for all social historical materials in ancient and modern times. It is now commonly understood as the sum of various publications such as books, periodicals, etc.

Materials, are some materials.

1. The concept is different.

Physical historical materials refer to all kinds of cultural relics, historic sites, ruins, buildings, inscriptions, sculptures and paintings, etc., although this kind of historical materials are mostly fragmentary, but it is a witness to history and a reliable historical knowledge, it can not only reflect the history more truly, but also have an intuitive image.

Historical documents are historical books written by people who are close to the era to be studied, and they are important historical materials for the study of the time.

2. The content is different.

Physical historical materials include production tools, means of subsistence, and relics of historical events.

Historical documents include written materials and oral materials. Oral information, on the other hand, refers to the words and deeds of human beings in the past that have been preserved through oral tradition.

3. The meaning is different.

Physical historical materials can make up for the lack of documentary materials and fill the gaps in historical research. In addition, the physical historical materials can be revised to distinguish the authenticity of the documentary records.

Due to the long period of time and social turmoil, many ancient books in our country have been scattered, and many records in the literature and materials cannot be verified, and many errors and omissions cannot be corrected and remedied, thus leaving behind many historical doubts. Many of these mysterious cases can only be solved through physical historical materials.

The difference between citations and references is in the content, purpose, and method of use.

1. The content of the citation is different.

The difference between citation and reference is that citation can be understood as being used to corroborate or illustrate the content of a document, while reference refers to the use of a certain document as a reference or reference in the written document.

2. Different uses.

Citations are found as a form of writing. It is mainly used in the fields of physics, chemistry and biology, and its main function is to conduct qualitative and quantitative and spatial positioning research on substances. In 1973, Lauterbur et al. first reported the technique of imaging using the principle of magnetic resonance.

Recently, magnetic resonance imaging (MRI) has been widely used in daily clinical work as part of medical imaging, and it is called magnetic resonance imaging in order to avoid confusion with radioisotope imaging in nuclear medicine.

The reference is a new diagnostic method that uses the resonance of atomic nuclei in the magnetic field to generate magnetic resonance signals to create images, which is used to detect the density of hydrogen protons, the flow rate of hydrogen proton motion, the relaxation time of T1, the relaxation time of T2, and the intensity of various scanning parameters that can produce MRI signals and affect MRI signals.

3. Different ways to use.

Using cited literature, the patient's bladder needs to be moderately filled, both as an anatomical marker for surrounding organs and to some extent to squeeze the intestinal loops out of the pelvis. and remove metal foreign objects from the body.

In contrast, the body coil or pelvic phased coil or intrarectal coil should be used for reference examination, and T1-weighted axial images and T2-weighted axial, coronal, and sagittal images are routinely used. Scanning sequence T, weighted image with conventional SE, TR600ms, TEL5 20ms; T2-weighted image base locust mill was detected with a fast spin-echo sequence.

**Introduction

** is a Chinese word, pinyin is lùn wén, a common word in classical literature, which refers to a conversation or exchange of ideas.

In contemporary times, ** is often used to refer to the research in various academic fields and the article describing the results of academic research, which is simply called**. It is not only a means of conducting academic research on the best issues, but also a tool for describing academic research results for academic communication. It includes academic year**, graduation**, degree**, science and technology**, achievements**, etc.

On December 24, 2020, the "Measures for Sampling Inspection of Undergraduate Graduation (Design)" proposed that the sampling inspection of undergraduate graduation should be carried out once a year, and the sampling proportion should not be less than 2% in principle.

References and literature are two different concepts.

Literature refers to all publications, including journal articles, books, reports, etc. Literature can be any form of publication, whether it is related to ** or not, it can be called literature. Literature is the foundation of academic research, and by reading relevant literature, you can understand the research results of Qiandouqing, and provide reference for your own research.

References refer to other documents cited in **, such as journal articles, books, reports, etc. The role of references is to provide the reader with relevant background information and a basis for supporting arguments, as well as to provide evidence for the author to read and draw on other research results. When writing **, you need to list the cited literature in the references and write it in a certain format to facilitate the reader's search and reading.

In general, literature is a broad concept that encompasses all publications; Whereas, references are a narrow concept, specifically referring to other documents cited in **. In academic research, the use of references is very important, which can not only enhance the credibility and persuasiveness of the reader, but also provide readers with more information and references.

Primitive Historical Materials: Refers to items that directly record events in history, such as stone tablets, inscriptions, ancient documents, manuscripts, and words written on the wall. 2.

Ancient documents: including ancient documents such as "Historical Records", "Zizhi Tongjian", "University", "Zhongyong" and so on. 3.

Oral History: Includes oral transmissions of events and oral history stories. 4.

Documents to be declassified: such as classified documents and intelligence documents retained by ** institutions and military agencies, which need to be authorized to be accessed. 5.

Printed materials such as newspapers, magazines, announcements, and advertisements: These documents can reflect the social outlook, values, and cultural inheritance of the times, and provide valuable historical research with their rich documents.

Literature materials refer to important reference materials with historical or scientific value used in scientific research to write scientific reports and academic **.

Literature originally refers to classics and sages, and when cited in writing, it refers to books and cultural relics with historical value, such as historical documents; One refers to important library materials related to a certain discipline, such as medical literature. Literature is written material that is often used as a basis for supporting opinions.

The basic elements of literature: knowledge with historical value and research value; a certain carrier; certain methods and means; A certain system of meaning expression and recording.

According to the content and processing depth of the literature, the literature can be divided into: zero literature, primary literature, secondary literature, and tertiary literature.

1. Unprocessed and published manuscripts, data original records and other documents belong to zero-primary literature, which is the basis of primary literature.

2. Monographs, newspapers, periodicals, patent documents, standard literature, conference documents, samples and other finished documents belong to primary literature.

3. Reprocess the primary literature, through sorting, refining and compressing, and sequencing according to its external characteristics (title, author, physical characteristics of the document) and content characteristics, to form another new type of literature form - catalog, bibliography, index, abstract, which is the secondary literature.

4. Using secondary literature, select the relevant primary literature and then analyze and synthesize the third-level literature form - special reports, reviews, purchases, sales, jokes, exhibitions, manuals, encyclopedias, yearbooks and other reference books, which are tertiary literature.

Literature refers to the knowledge with historical value and research value recorded in a certain carrier through certain methods and means, using a certain meaning expression and recording system. The so-called literature and literature refer to the written materials related to the canonical system, and dedication refers to people who are familiar with the history. Literature is the most effective means of recording, accumulating, disseminating and inheriting knowledge, and it is the most basic and main way to obtain information in human social activities.

The basic elements of literature are:

1. Knowledge with historical value and research value;

2. A certain carrier;

3. Certain methods and means;

4. A certain meaning expression and record system of Senpin.

Top 10 Literature Types: Periodicals, Patent Literature, Standard Literature, Degrees, Conference Literature, Books, Scientific and Technological Reports, Product Materials, Technical Archives, and Publications.

Literature retrieval system.

Literature retrieval system refers to a hierarchical system established in a certain way and method for readers to check information, and is a collection of information characteristics that characterize and order.

In this aggregate, the external characteristics and content characteristics of the information included in the collection are described in detail according to the needs, and each description record (i.e., paragraph) is marked with an identification that can be retrieved, arranged in a certain sequence, scientifically organized into an organic whole, and should have a variety of necessary retrieval means. Among them, the secondary literature information or tertiary literature information is the core and summary of the literature information system.
