Scholar’s Advanced Technological System

In the end, reason still defeated greed, Lu Zhou dispelled this unrealistic thought.

A freshman student published sci itself is nothing, anyway, the domestic sci journal irrigation phenomenon is also very serious, as long as your English skills are OK, irrigation and irrigation like this, then you can't pass.

This kind of phenomenon, so that a good person, listed a number of well-known irrigation journals in China. The top ranked, Applied-Mathematics &Computation (AMC), is famous in the field of irrigation.

Speaking of Shanghai University alone, in just four years, hundreds of mathematics papers were sent on AMC, and some irrigation users poured more than 20 articles a year.

In order to ensure the academic quality of the paper, those old-fashioned journals with regularity tend to strictly control the number of papers published in one year below 100. This "Big Mac" is a very skinny, with more than 1,000 papers published each year, plus cross-externalism and other factors, the impact factor is going up! Even due to the existence of a large number of pseudo-reviews, a certain editorial board issued more than 100 articles on it!

Other SCI journals, Lu Zhou, are not necessarily confident, but AMC's words...

Say he is confident and say that he is inflated.

In short, Lu Zhou feels that the problem is not big.

However, when the Zhou Cognitive Proof is published in the SCI journal, the problem is big. It is not a question that can't be passed. It is definitely possible, but the key is whether he can hold it after passing.

In the end, although Lu Zhou chose the third task, he was not prepared to use Zhou’s conjecture proof method, but to write a paper on the task.

His understanding of the two courses of advanced mathematics and mathematics is no less inferior to graduate students. Coupled with four levels of English, the distance between writing English papers is only a few professional terms, and these can be solved by looking up the dictionary.

On the other hand, the other two tasks, the first one he did not have that network, also recognized that there is not such a high emotional intelligence.

The second one, the freshman has not yet opened the big class, I am afraid that the system will brush out the high school physics exercises, the ghost knows how difficult the coefficient is. Moreover, the physics level is not so attractive to him. The name is only used in the late stage, and it is not too late to practice when necessary.

After selecting the task, Lu Zhou took a shot of the fart. The grass clippings on the stock, stood up and sang in the direction of the dormitory.

I have been delayed for a long time outside, and I will not go back. I am afraid that Liu Rui will be insane.

This kid is very strange, although it is usually very generous, but only in this aspect of learning, be careful to make people speechless. Take a look at the notes and chase you two streets. Asking a question can slap you a dozen or so eyes. It is probably this type of person. In his eyes, it seems that the world is his competitor, and what he is chasing is probably not academic height, but the first in the eyes of teachers or classmates, or the status of "study."

Is this kind of person a schoolmaster?

Lu Zhou does not think.

In the eyes of the real school, all mortals are slag, how about showing your notes to you? Zhou guessed you would? You can't understand it before you pose!

In Lu Zhou’s cognition, there seems to be only one person who meets the conditions of Xueba.

Well, that's right.

No doubt, he is talking about himself.

......

Pushing open the door to the bedroom, no more, just ten.

Liu Rui is holding the problem book to brush the questions, the other two are not in the bedroom, probably playing cards next door. Shi Shang is a person who usually listens to the lectures at the end of the period. As for Huang Guangming, it is probably the legendary **** of learning. He usually does not listen to the lectures. He holds the Buddha's feet before the exam, but the scores are high and the words are not like words.

Throwing the backpack on the table, Lu Zhou put his hand into the drawer to find his own bath card.

At this time, Liu Rui put down the exercise book on the handle and asked for the direction of the eye boat.

"Elbow, how hard?"

"I have to work hard. I haven't touched the book for half a semester. It's too late to work hard." The bath towel was thrown on the shoulder, and Lu Zhou stood up from the chair.

Seeing Lu Zhou going to take a shower, Liu Rui suddenly said: "I can't do it here. Can you help me?"

Oh, it’s amazing.

And what questions can you not do?

"Take it up."

Lu Zhou reached out and Liu Rui pushed the glasses and handed over the problem book on the handle. He pointed to the circled topic and said, "This is the way."

"Integration problem? This stuff should not be difficult..." The subject swept his eyes. The accident was a question that had not been seen. Lu Zhou came to interest, and did not rush to take a shower. He took the exercise book and sat back again. On the chair, pick up the pen and start writing on the scratch paper.

If it was before, it would be difficult to live with Liu Rui's question, he must not be able to solve it. I don't know why, at the moment, there is no such thing as "impossible" in his heart.

Looking at Lu Zhou for a while, Liu Rui was relieved, and his heart secretly despised the sentence **** is still learning slag, and then how to pretend to be a slag.

Regarding this question, he can't solve it without falsehood, but in fact there are reference answers, and there are detailed solutions on the answer. The reason why I asked Lu Zhou is not because I am open-minded, but just want to "sniff the enemy."

If you have to retreat 10,000 steps, even if you want to ask math problems, he will not find Lu Zhou.

Thinking about it, Liu Rui said: "Would you like to copy the questions? I will ponder the next question?"

The latent meaning is that you will not write anyway, I will not waste your time.

However, Lu Zhou’s reaction was unexpected to Liu Rui’s.

"... No, it's unlocked."

Solution, unlocked? !

Liu Rui’s eyes widened and he was surprised that his eyes were protruding.

"Well, you didn't get it wrong." Turning the ballpoint pen in his hand, Lu Zhou explained to the formula on the draft paper. "The typical double integral problem, the first step is to convert the Cartesian coordinates into polar coordinates and start the operation. Due to the interval symmetry, this part can be reduced to cotx2 by calculation..."

"Finally converted into cscx2 points! Then substituting into the original function!" Liu Rui's pupil slightly shrinks, keenly see through the core idea of ​​this solution, in the next step is like pushing the boat, it is OK to count down, no any Difficulty.

Damn, I didn’t think of this step...

"Bingo! Correctly." Lu Zhou smiled and nodded, saying that the scorpion can teach.

"Thank you... I borrowed the draft paper and I took the research and research."

"Get it, you're welcome!" Lu Zhou waved his hand and stood up and walked to the bathroom.

The draft paper with Lu Zhou returned to the seat. Liu Rui pushed the glasses and stared at the subject. The brow wrinkled slightly and fell into meditation.

Although the solution is novel, the process of solving the problem is clear, and the knowledge points involved are not super-excellent. Even without Lu Zhou's explanation, he can easily understand it.

Just let him not understand what happened, how did Lu Zhou think of it?

And still in such a short time...

Was it done in the past?

Liu Rui thought about it and seemed to have only this possibility. Otherwise, he really couldn't imagine it. This day and night, he was busy doing part-time school scum, and even crushed his recognized class in the speed of problem solving.

Turned to the back of the exercise book, Liu Rui looked at the answer solution, the whole person stunned and muttered to himself.

"impossible……"

The answer is completely correct... but this is not the point.

The point is that Lu Zhou's solution is even simpler than the standard answer solution! The answer does not take into account the solution of the Cartesian coordinates into polar coordinates, but the direct application of the formula to the second split of the integral, which results in an extremely large amount of calculation.

And this is one of the solutions he considered...

How can this be!

Liu Rui bit his lip.

Suddenly I feel that I have some doubts about my life.
