Is there a relationship between roller heat transfer and angular velocity?

It is true that angular velocity and velocity are not the same physical quantity, but they are both microquotients of time.

The word velocity is generally understood as a vector derivative of time. The word velocity is generally understood as a scalar derivative of time. For example, the temperature of an object changes with time, in order to study the speed of temperature change, the temperature is derived from time, so that the obtained physical quantity represents the speed of temperature change, we can call it "temperature change rate".

For example, in order to study the speed of a chemical reaction, we take a derivative of the concentration of reactants or products, and the "concentration change rate" is obtained.

If this heat transfer is related to this angular velocity, the greater the angular velocity, the more heat she heats, the more heat transfer must be.

Whether the heat transfer of the drum has anything to do with the angle speed, this should have a certain relationship, uh, the faster the speed, the better the angle, and the more accurate the installation.

Its speed is not directly related to its angle, so in this case it is related to its entire power and its bearing.

This has nothing to do with angular velocity.

The speed of heat transfer is proportional to the angular velocity.

The heat transfer of the roller is related to the angular velocity, and the faster the angular velocity of the roller, the slower the heat transfer.

Is there a relationship between heat transfer and angular velocity? This is related to the speed of the foot. His speed wears the heat of the moon this fast, too.

Roller heat transfer and angular velocity, in fact, should be related, speed affects the working machine, machine temperature how hot roller heat transfer reflects.

From a physical point of view, there is a relationship between their heat transfer and angular velocity, which is the relationship between the proportion of the spectator.

Drum heat transfer is related to angular velocity.

Employment prospects are also favourable.

Thank you for inviting a dog that has just been admitted to the postgraduate examination in 2019

I also have an undergraduate degree in electronic science and technology, because I want to continue my studies, I didn't change my major as a graduate student! There are many sub-disciplines under Electronic Science and Technology: Physical Electronics, Circuits and Systems, Microelectronics and Solid-State Electronics, Electromagnetic Field and Microwave Technology.

Let's see what direction you are interested in, I think you can get in touch with the hardware and software in graduate school, so the circuits and systems you apply for, because other directions can be said to be more directional! However, this is really related to the tutor you are applying for, and generally he has different topics under him, depending on what you want to choose! Be sure to choose a good mentor!!

Here's a quick rundown of my professional handles:

This major has a wide range of employment, because it involves the most popular directions now, and those who are going to graduate school can consider it! Finally, poke on the development board I'm working on:

There are a lot of options for the electronic information major of Magnan, whether it is employment or postgraduate entrance examination!

However, judging from the students who are admitted to graduate school, the vast majority of them continue to continue their studies in the professional direction of Electronic Information University, and there are still relatively few cross-level disciplines. The main majors are as follows:

Electronic Information and Communication Engineering.

After all, it is an old profession that I have studied for four years, and from the perspective of employment prospects, the electronic information major itself is a very good choice. Whether it is to work directly after graduate school, or to choose to continue your studies in the path of academic circles, there is a lot to do.

Computer Science and Technology.

Electronic information and computer major can now be said to be a brother major (optoelectronic major will not be talked about, to be honest, from the orthodox point of view, optoelectronics is a product of no kind, but the development momentum of its professional direction in China is still very strong), after graduate school telecommunications master's students do the work is basically the work content of programmers, knock ** to do software or web development, etc. Especially in the context of the popularity of artificial intelligence, electronic information is gradually weakening. However, telecommunications, as a very basic discipline, will not be erased.

Automation & Control.

In some colleges and universities, the electronic information major is under self-control, so it is not difficult to see the relationship between the two, but in other words, I personally feel that a large part of self-control students are also doing computer work, cry!

At present, the importance of interdisciplinarity is becoming more and more obvious, whether in the academic circle or in the industrial circle, the relationship between various disciplines is getting closer and closer, and the penetration of electronic information and computer technology into other disciplines and industries is more obvious, and it can be seen that both biological sciences and economic fields have these two figures.

But looking back, choosing which major to apply for depends on personal hobbies and future career planning, rather than thinking hard about wandering between majors, it is better to spend a little more time thinking about your own planning, if the goal direction is clear, and then to find a path, you should be much more motivated.

I am a student majoring in electronic information engineering at Xidian University, and I will briefly talk about my own views on electronic information science and technology.

Electronic information science and technology belongs to the category of electronic information, and electronic information is the first choice for postgraduate examinationOther relevant directions can also be selected.

First of all, let's talk about the direction of the graduate school entrance examination of electronic information science and technology. Contains:Electronic Science and Technology, Physical Electronics, Circuits and Systems, Microelectronics and Solid-State Electronics, Electromagnetic Field and Microwave Technology, Information and Communication Engineering, Communication and Information Systems, Signal and Information Processing, Control Science and Engineering, Control Theory and Control Engineering.

Which direction you choose for the graduate school entrance examination depends entirely on your interests and hobbies Look at what you like, because engaging in scientific research is a lonely and arduous process, if you don't like it, then you will end up making yourself very painful and helpless.

Let me briefly introduce itOur school is in the direction of electronic science and technology and information and communication engineering.

Electronic science and technology is a first-class national key discipline, and this discipline is a key construction discipline of the national "211 Project", "985 Project Advantageous Discipline Innovation Platform", and "111 Program Discipline Innovation and Intelligence Introduction Base". Its cultivation directions are mainly as follows:Big Data Intelligent Perception and Image Analysis, Nonlinear Circuits and Signal Integrity, Computational Intelligence and Machine Learning, Antenna and Microwave Theory Technology, Electronic Information Confrontation and Resistance, Integrated Circuit Design and New Semiconductor Materials, Infrared and Optoelectronic Imaging Technology.

Information and communication engineering is mainly trained inSenior engineering and technical talents in the direction of communication engineering, electronic information engineering, circuit and system engineering, electromagnetic field and microwave engineering, and optoelectronic engineering。With the continuous improvement of the level of electronic technology, electronic technology is evolving to photonic technology, and the close integration of photonic technology and electronic technology, communication and computer will promote the rapid development of communication in the direction of all-optics and build a new network society and digital era.

I am a senior in electronic science and technology, and I have studied the control major of this school. As for the direction, I think this major is still a wide range of majors, and there are intersections with many majors.

Aerospace, aviation, navigation. I was a graduate student who transferred to the relevant aerospace control. The research direction of graduate students will be biased towards aerospace control, but in fact, there is not much difference between what they do and the original major, and the three aviation departments are also inseparable from the talents of electronic information, if you are interested, you can find a teacher to understand the work or training program done by your graduate students.

2.Circuits and systems. This is the corresponding graduate direction of our major, and most of the students in our major who are admitted to graduate school choose this major.

This major will focus on electronic things, including hardware, software, and a combination of software and hardware. Of course, the employment will be a little broader, and basically go to large enterprises, which is also a good choice.

3.Automated Computers. In fact, these two colleges have the strongest correlation with electronic information, and I don't know what the difference is, it may be the reason why the resources of the two colleges of the school are better than electronic information, or it may be that the students chose to stay there because they found better teachers, but the employment and graduate studies in these two aspects are also very wide, so there is no need to worry about employment. Thank you

Fourth-year electronic information students come to answer a wave.

Electronic information science and technology mainly.

This is an interdisciplinary major that studies electronic technology, computer technology, and signal processing technology. It is more in line with the current development needs。In terms of subject complexity, the main courses cover a wide range of topics and may be slightly more difficult to understand.

This profession is mainly affiliated with:Electronic Science and Technology, and Optical Engineering, on the other hand, can apply for the corresponding second-level major.

For the first-level discipline of electronic science and technology, its subordinate majors may include:Circuits and Systems, Electromagnetic Fields and Microwave Technology, Physical Electronics, Microelectronics and Solid-State Electronics, etc

Circuits and systems can be learned relatively widely, from basic circuits to high-frequency circuits, to high-frequency circuits, image processing, machine learning, etc.

Electromagnetic field and microwave technology is mainly the research of radio frequency circuit and antenna technology, which is relatively professional and has a high threshold.

Physical electronics and microelectronics are more biased towards semiconductors such as chips compared to solid-state physics. For the current development situation, it is a more sought-after direction.

As for optical engineering, its direction is mainly to study the engineering application technology of various optics. Huazhong University of Science and Technology is relatively good at optical engineering.

All in all, different second-level disciplines, even if they belong to the same first-level discipline, may have large differences. In addition, the research direction of different teachers may also be quite different, so the choice of the teacher's research direction is not the choice of major.

Finally, thanks for adopting.

Regarding what direction can be taken for the postgraduate examination of electronic information science and technology, I am a sophomore student of electronic information engineering at Wuhan University of Technology, and I will prepare for the postgraduate examination next year to answer this question.

First, let's take a look at my own schoolWuhan University of Technology2019 School of Information Engineering Graduate Admissions Catalog.

At present, our school is in three directions, namely:Electronic Science and Technology, Information and Communication Engineering, Electronic and Communication Engineering。However, other colleges and universities also have other directions, as a whole, look at the figure below, in which electronic science and technology is more biased towards hardware, and most of the projects designed are related to integrated circuits, and they also need to master certain physical knowledge. Information and communication engineering is more software-oriented, involving signal processing, which requires a good mathematical foundation and computer programming foundation.

The two directions are detailed below:

Electronics & Communication Engineering: Electronic communication engineering isElectronic Science and TechnologywithInformation TechnologyIn the direction of integration, the basic theories of electronic science and technology and information technology are used to solve technical problems in the fields of electronic components, integrated circuits, electronic control, computer design and manufacturing, and electronic and communication engineering, and to study the theories and technologies related to electronic information.

Communication and Information Systems: YesInformation and Communication EngineeringThe secondary discipline under the discipline, the master of engineering in the field of electronic and communication engineering will design to telecommunications, radio, radar, remote sensing, electronic countermeasures and other knowledge, which are more cutting-edge and widely used technologies in the field of science and technology today, coupled with the information industry has become the pillar industry of China's national economy, the importance of this industry is also increasing, all walks of life are inseparable from information construction and maintenance, so the employment scope of graduates of this major is very broad, and the market demand is large.

But in fact, you have to combine the research direction of your graduate supervisor, after all, the supervisor will decide your specific research direction during your graduate school.
