After waking up from his sleep and lifting the quilt, Xu Chuan walked to the window, opened the curtains and opened the window.
The weather in mid-to-late October had already brought a hint of coolness, and the early morning breeze passed through the window sill, making him shiver involuntarily, and he quickly woke up.
Although he has found a suitable entry point and determined the research ideas for the problems related to the electromagnetic rail gun, it is not easy to solve this problem.
The problem of three-dimensional elliptical electromagnetic fields and high-dimensional large-scale backscattering is not only a difficult problem in the mathematical world, but also a cutting-edge scientific and technological problem in the electromagnetic field.
Those who study this issue are not just mathematicians, but also scholars in the field of electromagnetism.
Although it is not a popular issue, it is not unpopular either.
The scope of applications in the electromagnetic field is too wide, from military to civilian, from aerospace to electronic products, etc. It can be said that most fields in society today are more or less related to electromagnetism.
In order to help him understand and solve this problem more deeply, through the AI assistant, Xu Chuan collected a large number of papers on this aspect and learned the knowledge he needed.
It took him three days to sort out the information in these papers that was helpful for studying the three-dimensional elliptical electromagnetic field and high-dimensional large-scale backscattering problems.
On the fourth day, based on the ideas and methods he had found previously, Xu Chuan conducted in-depth research along the path he had opened.
On the fifth day, the first stage problem, the lowest-order edge element approximation problem for the calculation of three-dimensional electromagnetic fields with singularity, was successfully solved in his writing.
On the seventh day, through the adaptive finite element method, Xu Chuan completed the best approximation of discrete accuracy to optimal computational complexity and exponential convergence.
At this point, the process of this problem is already over halfway.
With the complexity quickly reduced, the remaining parts could no longer stop Xu Chuan.
Inspiration and ideas gather together like a trickle, constantly impacting this dam.
When the last drop of river water merged into it, the originally strong dam could no longer block the progress of civilization.
On the tenth day, a bright light in the morning rose from the distant horizon.
Sitting in front of the desk, Xu Chuan gently put down the ballpoint pen in his hand, stretched, yawned and stood up from the chair.
Originally, he thought that this problem might take him a month or two or even more, but he didn't expect that everything would go so smoothly.
It was so successful that he himself couldn't believe it.
In just ten days, the problems of three-dimensional elliptical electromagnetic fields and high-dimensional large-scale backscattering were solved in his hands.
Picking up the manuscript paper from the desk and looking at the mathematical work on it, Xu Chuan's lips curled up.
I have to say that for someone like him, this feeling of being completely immersed in the academic world is really very pleasant.
Even though he stayed up all night last night, he was in high spirits now.
After stretching his muscles and bones, Xu Chuan sat back at the desk again, tidied up the messy manuscript papers on the desk, stacked them together in order, and checked them twice carefully.
After confirming that there were no problems, he turned on the computer, quickly input the manuscripts into the computer through the scanning device, edited and saved the electronic files.
Xu Chuan was already familiar with the contents of what he was researching, and with the help of the AI assistant "Xiao Ling", it did not take him much time to sort out these things.
After checking the electronic files again and there were no problems, Xu Chuan said with a smile on his face: "Xiao Ling, send the files you just sorted out to Gao Hongming. Tell him that the problem has been solved and let him
Find someone to model the magnetic field control of the electromagnetic railgun based on the research above."
"Received, Master?('w')?get!"
A pop-up window popped up in the lower right corner of the screen, and the AI assistant's reply was as timely as ever.
"Master, the email has been sent. Is there anything else that Xiaoling can help you with?"
Looking at the reply, Xu Chuan smiled and said, "No, thank you for your hard work."
“It’s not hard, (*^▽^*).”
...
Beijing, in the Science and Technology Headquarters Building.
Sitting in his office, Gao Hongming was working on his work, wearing a pair of glasses and frowning as if he was thinking about something.
As the head of the Strategic Planning Department, the daily work he is responsible for is not simple.
Whether it is formulating a science and technology innovation development strategy, planning and coordinating implementation, organizing technology forecasts, undertaking the operation of the national major science and technology decision-making advisory system, etc., it can be said that each of them has a significant impact on the development of domestic science and technology.
Therefore, most of the time, he must be too cautious to think about the various impacts and consequences of a policy.
At this moment, the open door was knocked twice, and an assistant walked in quickly.
"Director, there is an email just sent from Academician Xu, saying that the problem you asked him to study before has been solved."
Hearing this, Gao Hongming quickly raised his head, with joy in his eyes: "Academician Xu's email? Are there any attachments such as papers in it?"
"Yes, do you want me to print it out?" the assistant quickly replied.
"Print three copies... no, five copies!" Gao Hongming said quickly: "In addition, help me arrange my air ticket and itinerary for tomorrow to go to Chubei Naval Engineering University."
"OK."
The assistant responded and walked out quickly.
In the office, Gao Hongming put down the pen in his hand, pulled out the keyboard and mouse, and clicked on the computer mailbox.
About five minutes ago, an email from Jinling was lying quietly inside.
Although he knew that he would not be able to understand the paper, he still clicked on the attachment in the email without hesitation.
"Research and Analysis of Three-Dimensional Elliptical Electromagnetic Fields and High-Dimensional Large-Scale Backscattering Problems"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Perhaps because I am not ready to submit it, this paper does not have an introduction or introduction at the beginning.
Starting from the first page, it is basically various forms of mathematical calculation tools.
Starting from the spectral theory of the Laplacian operator, to using the singular source field method to solve the far-field problem generated by plane waves, and then using the adaptive finite element method to complete the best approximation of discrete accuracy to optimal computational complexity and exponential convergence.
...
The contents of each item are arranged neatly and orderly on the paper. Although he cannot understand these and cannot verify the correctness of the mathematical calculations in the paper, Gao Hongming's eyes are full of joy and excitement.
Nothing else.
That person never failed to solve a math problem!
Now that he has given a solution, the magnetic field problem of the electromagnetic rail gun must be solved!
After flipping through the paper roughly, Gao Hongming picked up the phone on his desk and dialed a number.
"Academician Wang, regarding the research on electromagnetic rail guns, is there any progress on your side now?"
On the other side of the phone, a slightly tired voice came: "Not yet, there is still no good solution to the orbital ablation problem."
Although electromagnetic railgun technology is being carried out by many universities and research institutions, the main force in domestic research is naturally Chubei Naval Engineering University, which is linked to the Naval Equipment Department.
The person in charge of this project is Academician Wang Yong, dean of the School of Engineering, Naval Engineering University.
Although in the past year or so, they have successively solved some problems in precision guidance and electromagnetic track ablation.
But there is still a long way to go before the actual application of this technology.
Even if AI and algorithms are used to adjust and control the operation of electromagnetic railguns in real time, current technology cannot support electromagnetic railguns on ships.
In modern warfare, no one can bear the major flaw of a rail gun not having an accurate hit rate and having to replace the rail every forty to fifty bullets fired.
Although this data has exceeded the United States by several times, it is not of much use for the actual electromagnetic rail gun installation and application on ships.
In the office, Gao Hongming had a smile on his face, and he quickly said: "Academician Wang, do you still remember the feasibility study document you gave me before?"
"certainly."
Wang Yong nodded and said: "I remember you said you took it away to find Academician Xu? What did he say? Did he give some research directions?"
"Cough~"
Gao Hongming cleared his throat and said quickly with a smile: "Have you given some research direction? He has already solved this problem, does that count as giving some research direction?"
There was silence on the other end of the phone for a few seconds.
After a while, there was a reply with a slightly heavy breathing.
"Wait a minute, what you just said, there may be a bit of noise here, so I didn't hear you clearly."
Gao Hongming glanced at the paper on the computer, and replied with a cheerful expression on his face: "You heard it right, regarding the magnetic field problem of the electromagnetic rail gun, Academician Xu has already helped solve it!"
"Solved...Solved? How did he do it?"
There was an audible dry swallowing sound from the other side of the phone, and Academician Wang Yong's reply contained emotions of shock, surprise, and disbelief.
Upon hearing this question, Gao Hongming turned his eyes to the computer and read to the orderly paragraphs of the paper on it.
"It seems to start from the spectral theory of the Laplacian operator, to use the singular source field method to solve the far-field problem generated by plane waves, and then to use the adaptive finite element method to complete the discrete accuracy of optimal computational complexity and exponential convergence.
Best approximation... to solve this problem."
"I don't understand it very well, but I have the paper in my hands now."
"Do you have the paper?"
Gao Hongming grinned and said: "Yes, the paper is already in my hands now, but I can't understand it. I will send it to you later."
"Now! Send it now! I want it now!"
"Okay~"
Gao Hongming prolonged his voice and said with a smile: "I will send it now."
