Downstairs in the experiment, it was surprisingly quiet, with only hot wind passing through the air and the slightly impetuous chirping of cicadas.

At this time, everyone has their own affairs, and some of them plan to go back and finish the homework assigned by the main class in the morning while there is still a lot of time before the afternoon class. There are also people who want to go back to their rented houses in the neighborhood to get their afternoon textbooks, and some who want to go to their own clubs...... But so far, when they saw the boy and the girl going to the library, they couldn't move for a moment, as if they had forgotten what was going on urgently.

Who is this sudden passer-by?

In this science and technology competition team, the girls who gradually got closer to Jiang Hongshao, and when they went away, they all got together and kept looking at Cheng Ran's back.

Yuan Huiqun, who was beside Qin Qian, made a mouth shape to Zhang Ping with wide eyes, it was "What's going on?

Zhang Ping also shook his head in shock and confusion, "I don't know what the relationship between the two of them is, what is the relationship......"

Qin Qian was silent, looking in the direction of the library, her thin lips pursed.

For the participating teams present, no matter what the relationship between Cheng Ran and Jiang Hongshao is, what they care about the most is what Jiang Hongshao said.

Now their team was facing a problem, which even led directly to the question of whether the project could still be carried out. However, the time is tight, and the topic has already been reported, and even if it is feasible to make temporary changes, it is too late from the perspective of preparation.

The instructor asked his university professors for help, but the problem is that the reserves in this area are still insufficient, the so-called scientific and technological innovation, they take such a path, and they always have to come up with what their predecessors did not have, even if the current research is very shallow, but at least it is innovative. But they underestimated the difficulty, and a feasibility study on lithium batteries was not something that their knowledge reserve could successfully complete.

The embarrassment lies in this, since the students present have signed up for this science and technology competition, they are all the best students in this aspect of the grade, of course, not all the best students will come to sign up, but when we formed this team, it was discussed, and the instructor in charge was still in the teacher's office, and asked other subject teachers about the students with good grades in this area, and also mentioned to these students, "There is a science and technology competition, you are good in this regard, do you want to participate, you will win a prize, and it ......will be helpful to go on to higher education."

Among the students in the team, who is more powerful is also clear to each other. But I have never heard of such a person as "Cheng Ran".

Jiang Hongshao also told him about the current predicament, and invited him to the library together, so that he could discuss this problem with him in his free time...... It also means that he has such qualifications, and even has a good personal relationship with Jiang Hongshao.

Who is this man!?

Su Yang retracted her gaze, and only then did she notice that Qin Qian was also staring in that direction, and then she seemed to notice Su Yang's eyes, she turned her head, and the two of them looked at each other, but they didn't say anything.

It seemed that for the first time between each other, there was an inexplicable and awkward silence.

After a while, Su Yang said, "Your new friend, it seems that this aspect is good?"

Qin Qian let out an "oh".

Su Yang looked at the library again and said, "But this problem, even the team can't find a result in a short time...... It's not a ...... that one or two people can solve."

......

Jiang Hongshao and Cheng Ran walked side by side through the path of ginkgo biloba and big banyan trees, in fact, they have been seen by many people, but they did not cause much reaction, this is because Jiang Hongshao himself has a lot of affairs, so he often does not act alone, sometimes there are people around him, and there are boys, often belonging to Zhu Xu, or Liao Houming, a celebrity like the vice president of the student association, which is not strange.

But when the two of them walked side by side into the red door of the library, which was covered with creeper vines, all the people who bumped into the two of them here blinked, which was a little incredible.

Loud noises are never allowed in the library, so you can see a couple of young couples, or boys and girls who have a crush on each other, studying in this quiet place, occasionally whispering.

In the tenth middle school, if the boys and girls eat out together, maybe no one thinks there is anything wrong, but the library is a magical place, if the two walk into the library side by side, it will be meaningful, there will be "who and who entered the library together, is it already playing" remarks, often confirmed afterwards.

In terms of the rest of the library, it is simply the No. 1 holy place.

The two walked in like this, and collided with the students who originally came out of it, and a little boy saw Jiang Hongshao, his face turned red, and he turned around and walked back to the library, which was shy, and he would think that the girl he liked was a boy who was a beast, which was purely a normal reaction at ordinary times.

A group of men and women looked at them elusively, looking at them with strange smiles, all the way in their direction and then wrong.

At the self-study table, someone raised his head and saw this scene, hurriedly bumped his friend with his elbow, and when the other party rubbed his hand in pain, the corners of his mouth pointed forward to signal him to hurry up!

There are also girls who know Lao Jiang and wave to her to say hello, but their eyes stare at Cheng Ran without blinking during the whole process. That look is eager to interrogate him from beginning to end, if possible, Cheng Ran feels that the other party is one step away from saying something like "You turn around and put your hand on the wall".

Needless to say, this scene in the library will soon spread widely.

After leading Cheng Ran to the reading room, Lao Jiang said, "You wait for me." ”

Then she went to the relevant cabinet to get the reference book, Cheng Ran sat on the chair, and saw that she was sometimes frowning, sometimes thinking, sometimes standing on tiptoe, and taking the book with her body exposed, and even turning a book was quite pleasing to the eye.

After a while, I took six or seven copies, hugged them with both hands, and came back and put them on the table, during which Cheng Ran wanted to go over and take a hand, she said softly, "No." "A posture of doing your own thing.

This is really to check the information...... Isn't it a bit of a waste of this beautiful scenery?

Sitting down in front of Cheng Ran, Jiang Hongshao glanced at him, reached out and took out a pack of toilet paper from his trouser pocket, took out one from it, and handed it to him.

Cheng Ran was stunned, "Huh?"

Jiang Hongshao said, "Wipe your mouth, oily ......"

Cheng Ran was stunned and wiped it with paper.

Jiang Hongshao said, "You can...... I made new friends so quickly, and my popularity was good. ”

Cheng Ran felt that the corners of his mouth seemed to be a little stiff, "It's just a mistake......

Jiang Hongshao opened the book and looked at it, but it seemed that she could use it for two purposes, "This Qin Qian is quite famous...... It is a girl who really loves dance, the self-confidence of the dancer is not mixed with any impurities, vanity and arrogance have been polished clean in continuous practice, I have seen her dance, free to retract, it is a very high situation, without the corresponding mood is not reached. ”

"Praise so harshly, are you even praising yourself?" Cheng Ran thought of her dancing skills at the art show back then.

"It's not comparable, she's a professional ......," Jiang Hongshao said, "I'm just an amateur, I just know a little." ”

Then Lao Jiang smiled again, "Then again, I should thank her." ”

"Thanks for what?"

"Thank you for inviting you to eat this pig when I am not free...... Saved me a lot of money. ”

“......”

Cheng Ran knocked on the table and said solemnly, "What do you mean by your last sentence, don't you plan to take me to eat and drink spicy food?"

Jiang Hongshao glanced at him, "No money." ”

Cheng Ran smiled a little dazzlingly, "Then I'll invite you." ”

Jiang Hongshao was stunned for a moment, her eyes flickering, "It depends on the mood." ”

This was followed by silence between the two.

Cheng Ran looked at her with a smile, she buried her head in reading, and her ears were slightly red.

After a pause, Cheng Ran said, "Didn't you ask me to help you discuss the difficulties you encountered?" Why don't you ask me?"

"Excuse me?" Jiang Hongshao raised her head and looked at him with a look that didn't know whether she was angry or funny. After thinking about it, he stretched out a tender finger and pointed to the stack of books on the table, such as "Battery Principle", "Overview of Rocking Chair Batteries" and "Lithium-ion Research".

This time, she teased with a smile, "You finish reading this pile in three days, and the little woman will ask you ......"

Cheng Ran smiled, "No need, I'll answer you now." Silicon-based materials do have better capacity than carbon-based, but silicon materials will expand seriously during the lithium embedding process, resulting in a large loss of capacity. As...... Try carbon-silicon composites? This is the future. ”

It was only in 1992 that lithium-ion batteries were successfully developed, which greatly reduced the weight and volume of portable electronic devices such as mobile phones, laptops, and calculators in human society, but this era is still at the forefront of related fields.

In the future, the electric car called Tesla, the world's only battery technology, the use of anode materials, is carbon-silicon composite materials.

Of course, this deeper field is the result of a lot of scientific demonstration and practice in the laboratory, and Jiang Hongshao's project is just to explore a feasibility.

This conclusion alone is probably enough to deal with their problem.

A word woke up the dreamer, looking at his Jiang Hongshao, his pupils slightly contained a bright light.
