If you have any objections, please list the relevant scientific and technological literature indexes! ! ! ! ! !
The structure I proposed has been witnessed by others and basically recognized. You should propose a new structure.
Finite element analysis does not count, and analytical analysis is needed.
About a &；; The new system will be announced later, and some CDs have been distributed. Why not bring it up? This is their field of expertise.
Is the education system in our country backward?
Every country has its own environment and cultural traditions, and it cannot be generalized. MIT's teaching materials and courseware are published online for free, and Chinese people all over the world also volunteer to translate them. Anyone can learn, and there are many people who can be admitted. How many countries can be like him?
I once went deep into students' dormitories to guide students to learn analog circuits for free. I also bought components, materials, LCD panels and computers at my own expense to do experiments for them, help them build mathematical models and guide them to write patent documents for inventions.
General experimental problems, on the spot to guide them to solve. Even for students with good families, they provide non-repayable cash assistance.
I have always wanted to open a free video website to guide students all over the country for free. The school forbids me to use computers, oscilloscopes and servers, and there is no working space at all.
So we offended Hu Jun,
Perseverance after being laid off.
I suggest you write more with a pen!
None of the above statements are professional.
Pen jam
Is there any good way to solve the pen blockage?
After decomposition, use a toothbrush to wipe under running water; Dismantle the snorkel with the diameter of 1.5 mm and the multi-groove phenolic resin bakelite, insert it with a medical syringe, and spray clean it.
From the metallurgical industry, it is impossible to produce advanced alloy with corrosion resistance, low friction coefficient and wear resistance, which reflects the quality of key military materials and industrial bearings and vividly reflects the national defense strength.
As far as manufacturing is concerned, high-end special production equipment must be completely imported. The automatic production equipment of all kinds of pens produced in Germany is generally 3 million, which does not occupy the area. Moreover, the materials and accessories used for a good horse with a saddle must also be imported. Therefore, since the production of ballpoint pens before the Cultural Revolution, the quality has not reached the present; The good ones are produced by imported production lines, and some inks should also be imported; The technology of producing nib ball is also a true reflection of national defense strength. The country that can produce precision cemented carbide beads and ceramic beads in large quantities at low cost is an excellent equipment production industry, which is invincible in the field of military equipment such as ceramic bearings! !
Then, there are not many excellent pen maintenance personnel. In the past, old department stores had such a maintenance point, and the nib could be welded and polished again, because everyone had writing defects, and the nib was gradually worn off, and the golden tongue felt good when writing. If the nib is broken, it is necessary to weld the nib and keep the nib. Those who go to primary schools to fix pens just want to trick primary school students into having a golden pen and a golden tongue.
Whether you can repair your own pen is the embodiment of national quality and the theoretical level of thin shell mechanics. Does your pen feel astringent? Did it not go well? Don't miss such a good practice opportunity, don't entrust others, practice by yourself! This is consistent with the sheet metal process and the skill of adjusting bicycle spokes.
The popularity of computers and printers is attacking China culture and destroying China calligraphy.
Compared with traditional pens, ballpoint pens greatly waste the earth's non-renewable resources and destroy the environment. When most people reuse traditional pens, they enter an era of extreme shortage of earth resources.
In the early days of reform and opening up, teachers in colleges and universities focused on the teaching direction, and came to the conclusion that analog circuit teaching was basically cancelled, which was only in form, because the price and performance of foreign integrated circuits could not be replaced by circuits built with traditional discrete components in China; Since then, teaching, vocational education and home appliance maintenance have all centered on integrated circuits; Then in the information age, computer technology and network technology are the most important and core of scientific and technological development. Trenchless technology has been popularized in main roads, and directional drilling technology has been widely used in urban underground pipeline laying. This kind of underground drilling rig with steering drill pipe can be copied in China, with a set of imported 6.5438+0 million and a set of domestic 400,000. Guided ground penetrating radar must be imported, with a general performance of 300,000; Now this kind of radar is indispensable for urban construction, gas pipeline construction, underground cable construction and water supply system construction. House decoration and property management need a smaller ground penetrating radar, each of which costs 6.5438+0.8 million yuan. The traffic police's speed radar is similar. The gas company's high-sensitivity detection instrument for detecting the air leakage of thin pipes under roads is made in Germany, and a million-dollar instrument is also an analog instrument.
Looking at high-end instruments for deep space exploration, bioengineering, medical instruments, analytical instruments, high-energy physics research, biological origin, archaeological research and forensic evidence identification, all imported instruments dominate the world and are based on simulation technology. For example, Hubble telescope, black hole exploration, gravitational wave detection and satellite photos are all data obtained by using them. The input and output of inertial guidance system, mobile phone, base station, computer, TV, camera, scanner, video camera and other information equipment are mostly analog processing processes, but digital processing processes are adopted in the middle. Now analog and digital hardware and even software are integrated. Without basic design ability and semiconductor process equipment, we can only adopt the method of system integration. Advantages and greatest capabilities are algorithms and DSP. To be a large-scale commodity in the market, we must use other people's core software and hardware.
Put an end to what you can't do, and take the lead if you can't learn in this life!
The former is bound to unemployment, while the latter monopolizes resource power and endangers national security!
The biggest obstacle is that what can be done is not allowed to be done, and what cannot be done is in the hands of mediocrity. It's not a question of treatment, but there is no post at all, no access to the laboratory and no use of idle ordinary instruments.
Everyone has two sides.
Q @ # Do%...&; Directly affiliated units may have the right to use computers and networks funded by the state for many contract workers to enrich their spare time, and may also assign offices to contract workers.
At the same time, people who have been authorized by invention patents and published scientific papers at international academic conferences for many times have no workplace and are banned from using computers and instruments for decades.
It depends on who is different from who. It varies from person to person, depending on the specific situation.
Is it?
I can't finish reading all the books. I earn more than 10 thousand a month and don't want to go to class.
Laid-off workers who can answer students' questions on the spot and solve them immediately will receive social relief every month.
Q, director of the office, what do you say?
What slang and code words do you know?
An attacker with a senior professional title was ordered by the leader to drive a limousine and said to the victim, "You can call 1 10 to call the police!" Do you believe I can kill you on the spot? . He is an electronics major, but he can't design single-stage circuits at all. If he buys a multimeter below 100 yuan, he also wants the merchant to give him a large rebate. The paper to improve his professional title was copied from the textbook and asked other teachers to input it into the computer and print it for him.
Significance of the 17th National Congress of the Communist Party of China to Harmonious Campus
In the military industry, the slogan is that ignoring quality is a crime.
In the education industry, teachers who are unable to design and manufacture teaching equipment and industrial equipment and only transfer formulas from books monopolize the classroom, which is endangering national security and destroying the national foundation! People of this grade own luxury cars and have beaten people who have published papers at international conferences many times. It also shows that you can call 1 10 to call the police. Do you agree?
