Analysis of computational power

1.

Now the development of decentralized exchange is getting better and better, and more and more users have begun to use it. Why? Because decentralized exchanges are safe enough. Although the centralized exchange has many advantages, there have been many bitcoin theft incidents over the years, and the loss of users' assets is heavy, which makes many users start to be vigilant to the centralized exchange

the decentralized exchange can perfectly solve the security problems of the centralized exchange. Users have absolute control over their own assets, and the private key of the assets is kept in their own hands. Even if the private key of the exchange is accidentally leaked, as long as they can't get the private key of the user, they can't transfer the user's assets, which is very safe

moreover, the trading data and records of the decentralized exchange are accessible on the chain, open and transparent, and can not be tampered with. Any user can view them in real time, and the exchange cannot forge them. It solves the problem of transaction audit

therefore, if we enter the digital money market now, the decentralized exchange is a very good choice, and the technology is constantly developing and mature. Of course, we should also choose the head exchange

2. The bandwidth of the control system generally refers to the frequency when the amplitude frequency characteristic curve in the Bode diagram of the closed-loop system drops to - 3 dB. Note that this is the amplitude frequency characteristic of the closed-loop system, not the amplitude frequency characteristic of the open-loop system for stability analysis. The bandwidth of the control system is mainly determined by the zeros and poles of its closed-loop transfer function, which reflects that when the reference signal is higher than this frequency, the system will not be able to track with normal amplitude, so the larger the bandwidth is, the faster the frequency the system can respond to.

3. Do you have any questions about power electronic technology (Wang Zhaoan's)? What's more, is the question type of power electronic technology generally a question and answer or a calculation of power electronic circuits and electronics

4. Do you study finite element analysis software or pure theoretical finite element analysis? For the latter, you need to learn this course. For the former, basic mechanical knowledge is OK, mainly material mechanics, thermodynamics, dynamics and fluid mechanics

5. When doing ordinary problems, try to do oral arithmetic, so as to improve the ability of calculation. When doing problems, take the initiative to think, have the energy of not going to sleep if you don't want to come out, and then seriously look at the answers if you want to come out. The most important thing to learn is to be interested in mathematics. Otherwise, what I said above will not last long Home level players to adopt

6. If special phase is selected, no matter what kind of asymmetric fault, its three-phase state will be: the two-phase state is the same, and the other phase state is different. That is to say, another phase which is different from the other two phases is chosen as the basic phase. For example, if there is a single-phase to ground short circuit, the ungrounded two-phase state is the same, so the grounded phase is selected as the basic phase.

7. 1 Paper name
paper name is the name of the topic
first, the name should be accurate and standardized. Accurate is the name of the paper, what is the problem of paper research, what is the object of research, the name of the paper must be consistent with the content of research, not too big, not too small, to accurately summarize the object of your research, the problem
secondly, the name should be concise and not too long. Whether it's a paper or a topic, the name should not be too long. If you can't, try not to use more than 20 words
(2) the purpose and significance of research, the purpose and significance of research, that is, why to study and what value it has. Generally speaking, this can be discussed from the aspect of practical needs, pointing out that this problem exists in reality, which needs to be studied and solved. What is the practical role of the research of this paper, and then write the theoretical and academic value of the paper. All of these should be specific and targeted. We should not shout slogans aimlessly. The main contents include: (1) the background of the research (the proposal of the topic): that is, according to what and inspired by what to do the research. (2) through the analysis of the local (school) ecation and teaching practice, this paper points out why to study the subject, the value of the research, and the problems to be solved< (3) the history and current situation of the research at home and abroad (literature review)
there should be some norms, if it is a small topic, it can be omitted. It generally includes: Mastering the breadth, depth and achievements of its research; In order to identify the platform (starting point), characteristics or breakthrough point of this research, we need to find the problems to be further studied
(4) the guiding ideology of the paper research
the guiding ideology is what direction should be adhered to and what requirements should be met on the macro level. This direction or requirement can be philosophy, political theory, the government's ecational development plan, and the guiding opinions on research issues
(V) the goal of thesis writing
the goal of thesis writing is the specific goal to be achieved at the end of the project and the specific problems to be solved, which is also the predetermined goal of this thesis research: the goal positioning of this thesis writing, the determination of the goal should be closely related to the subject, and the words should be accurate, concise and clear. The common problems are: do not write research objectives; The goal is not tight; The target words are not accurate; The goal is set too high, and there is no research or no research on the predetermined goal< (6) the basic content of the paper should be more specific and clear. And a goal may be achieved through several aspects of research content, they are not necessarily one-to-one correspondence. When we determine the research content, we often don't consider it very specific. The research content written out is very general and vague. We regard the purpose and significance of writing as the research content
the basic contents generally include: (1) the definition of the name of the paper. Three points should be made clear as far as possible: the object of study, the problem of study and the method of study. (2) the definition of theories, nouns, terms and concepts related to the writing of this thesis< The specific writing methods can be selected from the following: observation method, investigation method, experiment method, experience summary method, case method, comparative research method, literature method, etc< (8) the steps of thesis writing
the steps of thesis writing, that is, the arrangement of time and order of thesis writing. The steps of thesis writing should fully consider the relationship and difficulty of the research contents. Generally speaking, it starts from the basic problems and is carried out in stages. There should be regulations on the starting time and ending time of each stage. The main steps and time arrangement of the research include: which stages of the whole research should be divided into; The start and end time of each stage.

8. 1、 Develop the habit of understanding things from multiple perspectives. Logical reasoning is carried out on the basis of grasping the internal and inevitable relationship between things. Therefore, it is of great significance to develop the habit of understanding things from multiple perspectives, to comprehensively understand the various relationships between the internal and external of things, and between something and other things. The first is to learn the thinking habit of "seeking differences from the same": compare the same things, find out the differences in a certain aspect, and distinguish the same things. At the same time, we must also learn the thinking habit of "seeking the same from different things": compare different things, find out the similarities in a certain aspect, and sum up different things. 2、 Imagination plays an important role in logical reasoning. Imagination plays an important role in the improvement of logical reasoning ability. To bring imagination into full play, we must first enrich our imagination materials and expand our scope of knowledge. The more solid the foundation of knowledge is and the wider the scope of knowledge is, the more imaginative you will be. Secondly, we should often process the image of knowledge to form a correct representation. Knowledge is only the basis of imagination, which does not mean that the more knowledge, the richer imagination. The key is whether we have the habit of image processing of knowledge and forming correct representation. Moreover, we should enrich our own language. Imagination depends on language and on the description of the formation of new images. Therefore, the quality of language ability directly affects the development of imagination. Only by consciously accumulating vocabulary, reading more literary works, practicing more and writing more, and learning to use rich language to describe characters and events, can we expand our imagination. 3、 Enrich the theoretical knowledge of thinking. In fact, there are differences in the degree of generalization, logicality and consciousness of reasoning, as well as formal differences in dective reasoning and inctive reasoning. And the development of reasoning ability follows certain rules. Middle school students should know more about the theoretical knowledge of thinking development, and consciously use the theory to guide the development of their logical reasoning ability. Generally speaking, there is an imbalance in the ability of middle school students to master and use all kinds of reasoning. For example, the correct use rate of inctive reasoning has exceeded 60%; The correct rate of dective reasoning is not close to 60% until the third grade of junior high school. According to this law, middle school students should learn to consciously use theory as guidance to promote the balanced development of their various logical abilities. 4、 Psychological research reveals that bad mood will affect the speed and accuracy of logical reasoning. Uncontrollable revelry, rage and crying, continuous depression, worry and fear, will have a negative impact on reasoning. Therefore, middle school students should learn to use consciousness to regulate and control their emotions and mood, so that they can keep calm and relaxed emotions and mood, and improve their logical reasoning level

9. If the deformation of the structure is relatively small, then the original geometric relationship is replaced by the deformed geometric relationship, which will not proce too much error
in structural mechanics, there is a section about the calculation of the second-order effect, which is what you said, considering the influence of structural deformation in the analysis. It is a nonlinear analysis. Simple structural mechanics problems can be calculated by hand to calculate the second-order effect. You can try to calculate simply supported beam or independent column, and you will find that the error caused by small deformation is very small. But the calculation process is troublesome.
