Chapter 836 Now! I Want It Now!

The next day, early morning.

Waking up from his sleep, Xu Chuan opened the quilt, walked to the window, drew the curtains and opened the window.

The weather in mid-to-late October was already a little cool, and the breeze in the morning passed through the windowsill, making him shiver involuntarily, and the whole person quickly woke up.

Although he had found a suitable entry point for the problems related to the electromagnetic railgun and determined the research ideas, it was not an easy task to solve this problem.

The problem of three-dimensional elliptical electromagnetic field and high-dimensional large-scale backscattering is not only a difficult problem in the mathematical community, but also a cutting-edge scientific and technological problem in the electromagnetic field.

Those who study this problem are not only mathematicians, but also scholars in the electromagnetic field.

Although it is not a hot topic, it is not unpopular either.

The scope of application of the electromagnetic field is too wide, from military to civilian, from aerospace to electronic products, etc. It can be said that most of the fields in today's society can be more or less related to electromagnetics.

In order to help himself understand and solve this problem more deeply, Xu Chuan collected a large number of papers on this subject through the AI ​​assistant, and learned the knowledge he needed from them.

It took him three days to sort out the materials in these papers that were helpful for studying three-dimensional elliptical electromagnetic fields and high-dimensional large-scale backscattering problems.

On the fourth day, combined with the ideas and methods found previously, Xu Chuan continued to study in depth along this approach that he had opened.

On the fifth day, the first stage problem, the lowest-order edge unit approximation problem for the three-dimensional electromagnetic field calculation problem with singularity, was successfully solved in his pen.

On the seventh day, through the adaptive finite element method, Xu Chuan completed the optimal approximation of the discrete accuracy of the optimal computational complexity and exponential convergence.

So far, the progress of this problem has been more than half.

The remaining part can no longer stop Xu Chuan's steps when the complexity is rapidly reduced.

Inspiration and ideas converge like a trickle, constantly impacting the dam.

When the last drop of river water flows into it, the originally extremely solid dam can no longer stop the pace of civilization.

On the tenth day, a bright light in the early morning rose from the distant horizon.

Sitting at the desk, Xu Chuan gently put down the ballpoint pen in his hand, stretched his waist, and stood up from the chair with a yawn.

Originally, he thought that this problem might take him one or two months or even more time, but he didn't expect it to be so smooth.

It was so smooth that he couldn't believe it.

In just ten days, the problem of three-dimensional elliptical electromagnetic field and high-dimensional large-scale backscattering was solved in his hands.

Picking up the manuscript from the desk, looking at the mathematical work on it, Xu Chuan raised a curve at the corner of his mouth.

It has to be said that for someone like him, this feeling of being completely immersed in the academic world is really pleasant.

Even if he stayed up all night last night, he is now full of energy.

After stretching his muscles, Xu Chuan sat back at the desk, sorted out the messy manuscripts on the table, stacked them together in order, and carefully checked them twice.

After confirming that there were no problems, he turned on the computer, quickly input the manuscripts into the computer through the scanning device, and edited and saved the electronic files.

Xu Chuan had already been familiar with the contents of his research, and with the help of the AI ​​assistant "Xiao Ling", it didn't take him much time to sort out these things.

After checking the electronic files again and finding no problems, Xu Chuan smiled and said, "Xiao Ling, send the files you just sorted out to Gao Hongming. Tell him that the problem has been solved, and ask him to find someone to model the magnetic field control of the electromagnetic railgun according to the above research."

"Received, Master ('ω') 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 Xiao Ling can help with?"

Looking at the reply, Xu Chuan smiled and said, "No, thank you Xiao Ling for your hard work."

"Not hard, (*^▽^*)."

In the headquarters building of Science and Technology in Beijing.

Sitting in his office, Gao Hongming, who was handling his work, was wearing a pair of glasses and frowning as if he was thinking about something.

As the head of the Strategic Planning Department, his daily work is not simple.

Whether it is formulating a science and technology innovation development strategy, or planning and coordinating its implementation, organizing and carrying out technology forecasting, and operating the national major science and technology decision-making consultation system, etc., it can be said that each one has a significant impact on the development of domestic science and technology.

Therefore, most of the time, he must be so cautious that he cannot be cautious to think about the various impacts and consequences of a policy.

At this time, 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 a look of joy in his eyes: "Academician Xu's email? Are there any attachments such as papers in it?"

"Yes, do you need me to print it out?" The assistant replied quickly.

"Print three copies. No, five copies!" Gao Hongming said quickly: "Also, please arrange my air tickets and itinerary for tomorrow to go to Chubei Naval Engineering University."

"Okay."

The assistant responded and walked out quickly.

In the office, Gao Hongming dropped the pen in his hand, pulled the keyboard and mouse, and opened the computer mailbox.

About five minutes ago, an email from Jinling was lying quietly in it.

Although he knew that he would definitely not understand the paper, he still clicked on the attachment in the email without hesitation.

"Research and Analysis of Three-Dimensional Elliptical Electromagnetic Field and High-Dimensional Large-Scale Backscattering Problems"

Perhaps because it was not prepared for submission, this paper did not have any introduction or introduction at the beginning.

From the first page, it was basically various forms of mathematical calculation tools.

Starting from the spectral theory of Laplace operators, to using the singular source field method to solve the far-field problem generated by plane waves, and then to the adaptive finite element method to complete the optimal approximation of discrete accuracy for optimal computational complexity and exponential convergence

The contents were neatly arranged in the paper. Although he could not understand them and had no way to verify the correctness of the mathematical calculations in the paper, Gao Hongming's eyes were full of joy and excitement.

Nothing else.

The mathematical problems that person completed have never been wrong!

Since he has given a solution, the magnetic field problem of the electromagnetic railgun must have a solution!

After flipping through the paper roughly, Gao Hongming picked up the phone on his desk and dialed a number.

"Academician Wang, have you made any progress in the research on electromagnetic railguns?"

A slightly tired voice came from the other side of the phone: "Not yet, there is still no good solution to the problem of orbital ablation."

Although many universities and research institutions are working on the technology of electromagnetic railguns, the main force of domestic research is naturally the Chubei Naval Engineering University, which is linked to the Naval Equipment Department.

The person in charge of this project is Academician Wang Yong, the dean of the School of Engineering of the Naval Engineering University.

Although they have solved some problems in precision guidance and electromagnetic orbital ablation in stages in the past year or so.

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 the deployment of electromagnetic railguns on ships.

In modern warfare, no one can tolerate a railgun that has no accurate hit rate and has to replace the rails every 40-50 bullets.

Although this data has exceeded the United States by several times, it is not very useful for the actual installation and application of electromagnetic railguns on ships.

In the office, Gao Hongming smiled and said quickly: "Academician Wang, do you still remember the feasibility study document you gave me before?"

"Of course."

Wang Yong nodded and said: "I remember you said you took it to find Academician Xu? What did he say? Did he give any research direction?"

"Ahem~"

Gao Hongming cleared his throat and said quickly with a smile: "Did he give any research direction? He has solved this problem. Does it count as giving some research direction?"

There was silence on the other end of the phone for a few seconds.

After a long while, a reply with a slightly strong breathing sound came.

"Wait, what did you just say? It might be a bit noisy here, so I didn't hear it clearly."

Gao Hongming glanced at the paper on the computer and replied with a cheerful expression on his face: "You heard it right. Academician Xu has helped solve the problem of electromagnetic railgun magnetic field!"

"Solved? How did he do it?"

There was an audible dry swallowing sound from the other end of the phone, and Academician Wang Yong's tone of reply was full of shock, surprise, and disbelief.

Hearing this question, Gao Hongming's eyes shifted to the computer and he began to read the neatly arranged paper paragraphs on it.

"It seems that it starts from the spectral theory of Laplace operators, and then uses the singular source field method to solve the far-field problem generated by plane waves, and then uses the adaptive finite element method to complete the discrete precision best approximation of the optimal computational complexity and exponential convergence to solve this problem."

"I don't understand it very well, but the paper is in my hand now."

"The paper is in your hand?"

Gao Hongming grinned and said, "Yes, the paper is in my hand now, but I don't understand it. I will send it to you later."

"Now! Send it now! I want it now!"

"Okay~"

Gao Hongming dragged out his voice, with a smile, and said, "I'll send it now."
