More than ten minutes later, Yuan Fuli and Qian Xuelin were stunned in front of a silver-gray laptop. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Ultra-thin display,Hundreds of buttons covered with the fuselage,As if a small fish ...... to swim out of the color dynamic desktop,The color of the picture is very bright,In this world with yellow、Gray、Black、White as the main color is so out of place,It makes people feel like they are in a dream。

Qian Xuelin and Yuan Fuli had both seen the typewriter and could probably guess the function of those buttons, but they couldn't understand the color ultra-thin display anyway, and they couldn't believe what they saw when they stared at the screen.

Yuan Fuli was not surprised by Qin Han's behavior of taking out some good things from time to time, similar to Tinker Bell, but this time it was so outrageous that it took him half a day to reflect, and he turned his head and asked Qin Han and asked, "What is this?" ”

"A 128-bit laptop is much more powerful than a calculator and can do 127-bit calculations."

"Calculations? Can this machine be used to calculate? Can it be accurate to 127 bits? Qian Xuelin, who thinks he is well-informed abroad, is also a little cramped in the face of his laptop at this time, and he has withdrawn his hand halfway when he wants to reach out and touch it several times, as if he is afraid of breaking it.

In an era when mathematical calculations are mainly carried out by slide rules and calculation books, and the accuracy of calculations is not very high, even the best scientists cannot understand the tools used to calculate 127-bit numbers.

It's like someone suddenly pulling out a laser gun or a maglev locomotive in front of us and giving us that feeling of disbelief and shock.

"Can you demonstrate that?" Qian Xuelin, who had recovered from the shock, was skeptical of Qin Han's statement, thinking that his statement was too mysterious.

"Of course there is no problem."

Qin Han had already prepared for Qian Xuelin's request, and when he brought this computer back, he had the idea of using a computer to pull top scientists. Computers are not valuable, but scientists are valuable, and it won't be long before a train of computers will replace a scientist.

A series of data was casually entered into the scientific and engineering calculation software in the computer by Qin Han, and when Qin Han pressed enter, a beautiful curve and a set of data were displayed on the screen.

Qian Xuelin didn't care about how many digits there were in that set of data, there was no need to verify this, what he was concerned about now was the speed - the speed of the thing called 'computer' in Qin Han's mouth.

"What did you just calculate? I see it calculates very quickly. ”

If the curve on the screen has to go through complex calculations, then this guy named Qin Han is not bragging just now, but is right to say it with reservations.

"This is the curve of the feedback-free fast-tracking function." Qin Han swiped his fingers along the beautiful curve on the screen, and stopped after only half speaking.

"What is no-feedback fast tracking?" Qian Xuelin's curiosity was completely aroused by Qin Han, and today he heard and saw too many things that he had not been exposed to before, which must be clarified - the persistence of scientists.

"I'll give you an example."

When we need to go out to purchase materials, we will send a buyer to buy them, but when the buyer arrives at the destination, he finds that the price of the things he needs to buy has risen, so he needs to return here to report and ask for instructions. This will delay a lot of time, and he will even find that the price has changed again when he goes back the second time.

The significance of no-feedback fast tracking is to predict in advance, so that buyers do not need to come back, so as to achieve the purpose of saving time.

"Feedback-free fast tracking can't be that simple, right?" Out of the intuition of a scientist, Qian Xuelin stared at Qin Han suspiciously and asked.

"Of course it's not that simple, this function is used to track missiles." Dotted the curve on the screen with his finger, and Qin Han answered Qian Xuelin's question as if he was talking about what to eat at night.

Missile?! Qian Xuelin's pupils instantly contracted like a needlepoint. Deep in the mountains of backward China, there is a scientific research team working on missiles? No kidding, right? Can primitive man study automobiles?

"You, you're working on missiles?" Qian Xuelin asked in a puzzled tone.

"To be precise, we are working on rockets, and the missiles are still too far away, and we are only doing preliminary calculation and derivation work. Of course, if we had a scientist like you to back us up, we would immediately dive into more in-depth research. ”

"But you've got a no-feedback fast track." Qian Xuelin asked.

The role of feedback-free fast tracking is not to track whether people go shopping, but to track missiles - long-range missiles. If a long-range missile stays in the air for a long time during its flight, it will have to pass through many different climatic zones during its flight, and its flight trajectory will certainly change in windless and windy climatic zones.

If this change is fed back and then issued by the control center, this information will inevitably go back and forth for a period of time, and sometimes it is a little bit of time, which may cause irreparable losses. The role of feedback-free fast tracking is to omit the feedback process, which is the fundamental purpose of feedback-free fast tracking.

Qian Xuelin's heart was extremely shocked, when radio remote control was still being carried out abroad, it was unbelievable that China had already begun to engage in non-feedback fast tracking. But when faced with this computer that still shows that beautiful curve, everything is so normal.

Such a time-saving, labor-saving, and accurate calculation tool, how can there be no research results, if you have this thing in hand, I am afraid that the research project in hand has already ended, right?

Qin Han didn't continue to discuss the problem of fast tracking without feedback with Qian Xuelin, but just turned the computer in a different direction and operated it on the keyboard, while casually asking, "Does Mr. Qian have any research on pneumatic layout?" ”

"Pneumatic layout? You should be referring to the aerodynamic layout of the aircraft, right? This belongs to the aerodynamic problem, and it is also what I am ...... now" Qian Xuelin paused in the middle of his words, his eyes stared at the computer screen, and the whole person seemed to be petrified.

Almost instantly, the petrified Qian Xuelin rushed to the front of the computer, pushed Qin Han away, pointed at the screen with his finger and said, "That's it!" That's it! It's supposed to be like this, it must be like this...... ”

Crazy, completely crazy, for about 5 minutes, Qian Xuelin kept muttering and shouting, and Yuan Fuli was also staring at the screen with bright eyes, without saying a word.

Suddenly, Qian Xuelin seemed to think of something, turned around and grabbed Qin Han, asked in a hoarse voice with red eyes and a hoarse voice: "Qin Han, tell me, tell me quickly, what is it called, what is it called!" ”
