In general, good journal articles have more ideas. Although read more tired, but harvested more in-depth, so more worthwhile to analyze.

A journal article, mainly divided into four parts.

1Abstract

Describe the main contribution of this paper, the method features and main content. The slowest master two semesters must learn to look at Abstract and Introduction can be judged that the focus of this paper and your research is not directly related to decide whether or not to finish it. If you have the ability to select only the five papers that are most relevant to every 30 papers based on the abstract and the introduction alone, you are more than five times more efficient than others. Later, whether it is doing things or doing academic research, than others have the ability to pick the most reference from the broader literature.

2Introduction

The function of Introduction is to introduce the background and origin of the problem, to explain the predecessors' major contributions to the subject, to clarify the unresolved problems left by the predecessors, and to the problems that this thesis wants to solve in this context The importance of For beginners, here is an overview of previous research. Usually I would advise beginner students, when you are unfamiliar with your topic, first collect 30 to 40 papers that may be related to your topic, each of which is Abstract and Introduction, and not Main Body, only if necessary Refer to the Illustrative example and Conclusion later on until you can answer the following three questions:
(2A) What are the most commonly quoted methods in this area?

(2B) What are the major factions into which these methods can be divided?

(2C) What are the main characteristics (including pros and cons) of each character faction?
The question is, how do you find the first 30 ~ 40 papers? There is a journal article called review paper, which specializes in organizing all relevant essays under a single topic and makes a brief review. You can filter out such papers by adding a review to the key words when searching Compendex. Then, starting from the relevant review papers, find 30 to 40 papers that you think are more relevant to your research topic, based on the title and the abstract.

In general, you should be able to answer both (2A) and (2B) from the Introduction's comments as long as you have repeatedly read the Abstract and Introduction of 30 to 40 papers in this area. In particular, remember that when reading for the purposes of answering (2A) and (2B) these two questions, you have to pick up some more introductory essays written by Introdution (many papers are written like drafts , No idea, do not read it at the beginning of this essay). If you read 30 to 40 papers Abstract and Introdution, or can not answer (2C), the first to do the following work.

First, according to (2A), find the most frequently quoted papers in the field and divide them into groups according to (2B). Each is ranked in chronological order. Then, each time you re-read only the other Abstract and Introduction factions, read them according to the dates, and read only to try to answer this question: What are the initiatives and main demands of this group? In this way, you send the Abstract and the Introduction of each faction to each party, and summarize the main demands, methods, features and merits of each faction. (Each essay goes back to its own merits and will not be missed if you read it carefully.) Off).

Second, you take these essays out again, but read-only Introduction, answering the following questions seriously: What criticism of each essay over other factions? Then you record the key points read in each box's shortcomings column.

Through the above procedures, you should be able to grasp the answer to the three questions (2A), (2B) and (2C). At this time, you are quite familiar with the main methods and the literature in this area, but you still read Abstract and Introdution only, and the internal texts are only read extensively.

At this time, you have mastered the main papers in this field, you can use these papers to test to see if you are in search of domain papers keywords in the end pinch inappropriate, and search for a paper with the revised keywords, the field The main literatures are supplemented, and the papers that were later found in 30 to 40 papers were also screened out, leaving only about 20 articles that are determined to be close to you. If you are certain, you can even delete one or two factions you do not want to use (for good reason) and keep only two or three factions (and for good reason).

Then you should use the answer to (2C) to answer one more question (2D): What are the key issues that are considered important in this area? What are the characteristics we all attach importance to the advantages? What are the characteristics we are really care about? These advantages are usually shortcomings in which applications will be more emphasis? In what occasions will not be more attention? Then, you can sort out the main applications in this area (research topics) and what to look for in these applications.

Finally, before you actually start reading the main body of an essay, you should first organize the essays in the factions into the same folder based on the answers to (2A) and (2C) and find the time sequence. Then, according to the relationship between these factions and your research direction, one faction factions each faction each faction one by one after the faction's main body.

3Main body

The first time you systematically host the main body of a particular faction, you need to understand:
(3A) What is the main assumption (under what conditions is it valid) for this essay, and to assess how easy (difficult) it is for these hypotheses to be realistic. The more difficult to establish the hypothesis, the less useful, the lower the reference value.

(3B) Under these assumptions, what are the main benefits of this paper?

(3C) These benefits are mainly reflected in the simplification of those formulas.
As for the detailed derivation of the whole thesis, you do not need to understand it. In addition to the three or five key formulas (the last to be used in the application of the formula, from here you can assess the ease of use of this method or computational efficiency, and in the non-ideal situation to use these formulas reliability or stability Sex), the other formulas do not understand it does not matter, the formula between the equality of the derivation process can be completely ignored. If you look at the formula, the point is to look at the assumptions introduced in the formula derivation rather than the conversion of identities.

However, before you start your year-long essay based on the aforementioned questions, you should first take out all the essays in that faction and go through the rough passages of the past (do not force yourself to get each line read but read it with ease , Understand understand, do not understand do not understand), pick out easy to read papers, and often cited papers. Then read theses chronologically in sequence. I remember: when you read the answer (3A), (3B), (3C) three questions just fine, do not read too fine.

After you have done this, you should make a complete arrangement of the major development processes, major assumptions, major theoretical bases, and major achievements of this faction. Second, you will further answer the next question based on the (2D) answer and the main assumptions of this faction: (3D) What are the main weaknesses of this faction?

Finally, according to (3A), (3B), (3C) the answer to sort out: This group is best suited for when to use, the most suitable for what occasion.

Remember: When answering these questions, you still should not know how identities are derived!

When you are a living hand, you often have to refer to its examples when evaluating the strengths and weaknesses of a method. However, remember: Experienced essay writers deliberately present only successful case two to cover up failed cases. So, a good simulation example and / or experiment does not necessarily mean that this method is really good. You have to go back to the basic assumptions of this method and the resultant solutions he uses in applying his own thinking skills and referring to the answers to (2C) and (2D) , Predict which method should be used in which conditions (applications) outstanding performance, under what conditions (applications) out of condition? According to speculation in the test a simulation examples and / or experiments, see its strengths and weaknesses are not really fully tested in these examples, and fully demonstrated.

So, when do you need to understand all the equations derived from a thesis, or read the entire essay carefully? Never! You just have to figure it out, The part that will be used is enough to know its main idea.

The main difference between master students and college students: What students must read from scratch to read all know, master only need to understand the part he needed just fine! Because college students face a fixed range of knowledge, so he read. Master's knowledge is no scope, so he only needs to understand the level of sophistication he needs is enough. Master must learn selective reading, and must exercise the accuracy of his choice and the speed of choice, do not waste time learning the details of knowledge do not need to! More absorption "ideas" more important, rather than detailed knowledge.
