Chapter 1341: Implicit Density General Function Method

Young's modulus ≥ 2.1TPa, destructive strength ≥ 80Nm...

From the set of parameters given here alone, the first thing the ship thought of was a cable with a very high tensile strength, and then the shock-resistant paint used on automobiles or aerospace equipment.

As for where this thing can be used...

That's a lot of use.

Simply to be used as a cable, it can be used on the space station from the sky as a traction rope for fixing heat sinks and solar panels, on the ground as suspended material for engineering equipment, and down to the sea as a barrier rope on the aircraft carrier deck.

Especially the latter, which is not very expensive.

And these are just one of the uses of this material.

The Ark believes that after the advent of this high-Young's modulus, high-destructive material, there must be countless people who can come up with something for him that he didn't even expect.

Return to the study itself.

For this technical standard given by the system, the best option the ship can think of is having a carbon based material with high tensile strength, weight and plasticity.

Especially reinforced composites of a range of graphite-derived varieties such as carbon fiber.

This material has a vast imaginary space, not only in theory, but also in computational materials research, which is his old-fashioned business. When he started doing computational materials, he started with carbon materials.

Thus, the task was arguably without difficulty for him.

It's like giving away for nothing!

After leaving Professor Wang Qingping's lab, the Ark did not stop more at the Jinling Institute of Higher Studies, but returned straight to his home.

Previously, when he was modifying that mathematical model against the results of the experiment, he suddenly had some thoughts in his mind about the theoretical study of computational materials.

Perhaps because both mathematics and physics rose to LV10, the ark found itself sensitive to digital and physical phenomena and had reached the realm of divine indoctrination.

Even a tiny, almost negligible clue can be infinitely amplified in his eyes into a key that can be touched by both hands.

Wherever this inspiration comes from, there is only one thought in his mind right now.

That is to record it while the inspiration is still intact.

After coming upstairs to the study and telling Em to make herself a cup of coffee, the ark sat at the desk and lay the draft paper brought back from the lab on the table.

“Material A density synthesized according to the experimental process designed by the original model is low, a fluffy mass is formed after deposition, and the diameter of the carbon nanotubes is extremely uneven…”

“This result should be due to the inadequate reaction of the monomeric acrylonitrile through radical polymerization, which resulted in a large number of intermediates, resulting in inadequate reaction in the third stage… and finally in the formation of that foamy mixture. ”

“Tsk, that's funny. ”

What interests the ark is not the foamy mixture, but some very interesting phenomena that he discovered when revising the computational model.

After a while of careful reflection, he picked up his pen and wrote a whole line of words on a blank draft paper.

Implicit Density Pan Function Method

Looking at the line as inspired by the writing, the corner of the ark's mouth held a smile.

In general, when a difficult issue is clearly written down, it is half solved.

At least for him!

The so-called implicit ubiquitous function density is a method of computational materialism relative to the explicit ubiquitous function density, which is a relatively popular research direction in the field of theoretical study of computational materialism.

It is well known that traditional interchange-related energy ubiquity functions are explicit ubiquity functions expressed directly in electronic density functions, whereas Kohn-Shan orbital wavefunctions are implicit ubiquity functions as direct variables.

The simplest implicit ubiquitous function is FOCK exchange energy, often referred to as precise correlation in the context of density ubiquitous function theory.

For molecular systems, the use of implicit ubiquitous functions achieves an accuracy equivalent to that of second-order multibody micro-disturbance theory at relatively small computations, so the implicit density ubiquitous function method is widely regarded as a computational material research method with broad prospects.

However, while there are points such as these, their shortcomings are also evident. For example, limited accuracy, including inability to accurately describe Van der Waals interactions, is almost fatal for studying solid materials.

Consequently, implicit density fusion methods are relatively rarely applied when studying solid materials, and only some progress has been made in certain areas… and this is in the context of a significant increase in computational power.

At present, there is widespread academic interest in implicitly related general correspondence based on the theorem of dissipation of heat insulation associations, which is widely regarded as a breakthrough in studying the inadequacies of implicit general correspondence density.

However, the problem of such general correspondence is not insignificant, especially as large computational volumes can be challenging even for the most powerful traditional computers, so the research direction is still in the exploratory study of simple systems.

And what the ship is going to do right now is to extend this approach from a simple system to relatively complex carbon material research!

Once this study is successful, it will help the entire field of carbon composite research immensely, and will even exceed the material itself that he is studying with a "Young's modulus ≥ 2.1TPa, destructive strength ≥ 80Nm…”!

The pen on his hand did not pause at all, and the ark after completing the title quickly went deep into the exploration of the proposition itself.

[According to the H-K theorem, the basic energy generator of the system can be expressed as: EG {P (r)} = E {P (r)} + V (r) ρ (r) dr...]

[And the generic letter E {P (r)} can be expressed as: E {P (r)} = T {ρ (r)} +12 × {ρ (r) {ρ (r) drdr + Exc {P (r)}...]

……

A line of formula flows out from under the tip of the pen, like a trickling stream of water, along with the outburst of inspiration into a river, running into the sea!

All the inspiration for matter, the numbers that are visible at this moment, is woven into a language that can be recited.

And under the veil of this giant net, all the forces and physical properties are encapsulated, all answered by that tight to trembling logic abstract into mathematical language and by mathematical methods!

“Then it was the introduction of the Shrodinger equation--”

Gently in his mouth, he was pinched by an ark at the tip of his finger, like a sharp dagger, drawing a powerful trajectory on the paper, while also piercing the fog that covered the end of the maze.

Looking at that almost leaping paper result, the pupils of the ark became brighter and the slightly locked eyebrows finally relaxed a smiling curve.

Though we don't know how far to go from the finish line.

But scientific intuition has told him that he is very close to the end!

Time goes by.

The sun also gradually moved from the sky to the edge of the sky.

As the sky outside the window finally darkened completely, the street lights on both sides of the tree-lined trail began to light, at this moment the ark finally raised its head and breathed a long breath, stopping its hand from being pinched almost to a febrile pen.

“… the implicit density ubiquity method also holds great promise for the study of carbon composites, at least now it has been extended to this field. ”

“At the same time, this could be a breakthrough in extending the approach from simple to complex systems. ”

“Although there is still room behind this for further excavation. ”

“But that's it for now. ”

Go ahead, the ark laughed with some satisfaction and put the pen in its hand aside.

And almost at the same time he had just put the pen down, a line of light blue text appeared unexpectedly in front of him.

At first, I thought I was mistaken, and I blinked consciously under the ark.

However, that line of light blue text, not half dimmed by his wink, is still that clear and unoblivious...

Congratulations host, complete the task!
