This is a technique that I teach for a set of technical books to me. Although it is based on the maximum entropy principle, it is actually not so deep. As for your right, you should look at it first.
Suppose you get a very important and important technical book for you, and you must read it in a limited time. At this time, the first thing you have to do is to read the directory of this book. Grasped the catalog, you grasp the content of the book. Take the chapter marked on the catalog into a tree, just like learning the data structure: The root node is the title of the book, the first layer is chapter, the second layer is the section, the class is pushed.
Draw this tree, will you think it is a bit imbalance? For example, the leaves on some branches are particularly more, but some may be just empty branch? Um ~ The chapter of the leaves is the focus of the book! You extend from the left and right sides from the leaves, see what the relationship between the non-heavy chapters and key chapters - is a knowledge paving, or other shrimp? At this time, you should be able to get roughly how to treat those non-heavy chapters. Of course, there is also a possibility that the book is evenly distributed, then you can think that they are all focusing (only a good technical writer should avoid writing such a book).
In the key chapter, you have to continue to analyze the relationship between adjacent leaf nodes - is a transition, transition, progress, or turning? It's all the top priority you have to grasp! Grasping this level, you basically have a general understanding of the general idea of the book.
Here's of course starting over the directory reading text. However, don't worry about reading each sentence, remember that it is always good to save more time without affecting the effect. In fact, the best practice is to read the first paragraph (even just the first sentence) in the book. By the way, some netizens may ask: If the author is in the first step, it will lead the victorious victory.
Oh, you have a lot. This is not a novel poetry prose, which is technical. The first paragraph of technical text will always open the door. If this is not the case, then you have to give it that your hand is not a science fiction. Remember, read the first paragraph calmly, and find a key statement so that you can continue to help you understand the research ideas and methods used by the author in every knowledge point, and the contradictions that need to be resolved.
When you come here, no matter what you are in your hands, you can fully understand where you should read it. You can release those things that you think about you. After reading, you can boldly pick the book, the arrogant to you, the comrades who have had to collee them, read the fade of the focused, said: "Hey, I have mastered this book with the contents of ten, I ... "
