Li Mowen's smile instantly froze on his face, and he said coldly: "Zhang Yi, it's just a meal to enjoy your face, we will have to work together in the laboratory in the future, you don't want us to cooperate unhappily." ”

Zhang Yi didn't know if Li Mowen was really stupid or had low emotional intelligence, so he actually said this kind of thing in front of the girl he liked, but he didn't have time to accompany him when chasing girls was up to him, "I'm sorry, I really have something to do tomorrow, and I really can't go to dinner, just go." ”

As soon as Zhang Yi said this, Xia Jingyan hurriedly followed suit: "I see that everyone is very busy, let's forget about eating." ”

After Zhang Yi finished speaking, he didn't care about him anymore, and walked straight to Liu Rui, and said in his heart: "You can chase your sister, with your own ability, I don't have time to play with you." ”

Xia Jingyan also hurriedly followed, leaving Li Mowen biting his cheeks and stunned in place.

......

The Shisei-building has 6 floors, and the bottom 3 floors are all classified as mining projects, which shows the status of mining in Shisei-in.

In the 3rd floor, the 1st and 2nd floors are laboratories, and the 3rd floor is the teacher's office.

There are more than 20 laboratories on the two floors of the mining industry, each of which has a specific teacher in charge, which is usually convenient for the graduate students led by the teacher to conduct experiments in it.

Professor Zhong has two laboratories that belong to him in charge, which is equivalent to giving him a special purpose, and the instruments and equipment in them cannot be used by others, and other professors also have laboratories like this, and some of them are shared laboratories, and the equipment in them can be used by all graduate students.

Liu Rui took the three of them to visit the laboratory, explaining the use of various instruments from time to time, Xia Jingyan showed great interest, and kept following Liu Rui, and kept asking questions when he encountered something he didn't understand.

Zhang Yi couldn't be more familiar with the instruments and equipment in the laboratory, so he was also lacking in interest, and coming to visit the laboratory was just a soy sauce.

However, what is rare is that Li Mowen acted like he was fine, and he was not affected by the unhappiness just now, and still listened to Liu Rui's explanation very carefully.

When Zhang Yi left the laboratory, it was already 12 noon, so he simply ate in the cafeteria and went back to the dormitory for a nap.

This night, Zhang Yi slept until 3:30 in the afternoon, and after waking up, he felt refreshed, and after a simple wash, Zhang Yi went to the library.

To go to the sulfuric acid slag project, Zhang Yi is very confident in terms of technology, but he is not familiar with engineering construction.

Although the test plan has not yet been finalized, and he does not know how much money to invest and what equipment to purchase, it is still possible to be prepared.

The library just had these materials, and in '98, you could easily find the materials you wanted on the Internet, unlike later.

At that time, information technology was not developed enough, and the materials depended entirely on the books in the library, and the things in the books took a lot of time from writing to printing to publishing, so the information obtained would lag behind.

However, Zhang Yi knows the changes in prices, and with a little conversion, he can almost estimate the prices later.

On the fifth floor of the library, all natural science books are stored, it is now the afternoon time, there are not many students reading books on the entire fifth floor, and two people can sit on both sides of the large table for students to study, and there are many empty seats now.

Zhang Yi found a few books on the shelf, then found a corner to sit down, he brought his own notebook and pen, and he could write down in the notebook if he saw something useful.

"Zhang Yi, you're also studying in the library. Just as Zhang Yi lowered his head to write and draw in his notebook, a sweet and glutinous voice sounded in Zhang Yi's ears.

Immediately a familiar fragrance came to his nose, Zhang Yi looked up and saw that it was still the white dress in the morning, but I don't know if it was because he had just gone to the fifth floor, and he was still working hard to find the books he needed on the shelves, and Xia Jingyan had small beads of sweat on his nose.

"What a coincidence, you also come to the library to study? Xueba is different, and he refuses to let go of any rest time. Zhang Yi put down the pen in his hand and looked at Xia Jingyan, who had just sat down opposite him, and said.

Xia Jingyan's face turned red, and she said softly: "Don't make fun of me, I'm not a scholar, I'm about to do an experiment recently, and I don't understand something, so I came to the library to read some books." ”

Zhang Yi glanced at the book in Xia Jingyan's hand, solution electrochemistry, this book is good, and the content can be used now, but knowledge needs to be accumulated, now Xia Jingyan is a junior student, and it is still too reluctant for her to do such a difficult test as tungsten molybdenum separation.

Since she met here, Zhang Yi might as well help her, "I have studied the topic of tungsten and molybdenum separation a little before, you can ask me if you don't understand anything, I will tell you what I know, and I will be embarrassed if I don't know." ”

"Really? That's great, I don't know much about mineral ions. Xia Jingyan was also a little happy when she heard this, and said softly: "Our teacher said that the direction we need to study is the reaction mechanism of ions in aqueous solutions, but I don't know much about the existence and reaction process of mineral ions in aqueous solutions. ”

After listening to Xia Jingyan's words, Zhang Yi was stunned, these things she said will not be learned until at least when she is a graduate student, and she is still learning basic theories when she is in the first year of study, and she will learn the reaction mechanism in the second year.

Zhang Yi also often uses this knowledge when doing scientific research and analysis, but it is obviously impossible for him to say a theory now, and then Xia Jingyan immediately opens up.

What these things need to be accumulated slowly, and it takes more work and more learning to do it, what Zhang Yi can do is to let her take as few detours as possible and master these skills as soon as possible.

Zhang Yi pointed to the book in Xia Jingyan's hand and said: "Like this book of solution electrochemistry in your hand, it is just a basic theoretical book, so let's do it, I will recommend a book to you, you can read it when you have time." ”

Zhang Yi wrote the title of the book, the name of the publishing house and the name of the author in the notebook, then tore it off and handed it to Xia Jingyan, "The mechanism will not be clear for a while, this book not only has the reaction theory of ions, but also combines some examples to analyze, a beautiful student like you, it's not a piece of cake to get this." ”

Xia Jingyan's face turned even redder after receiving the note handed over by Zhang Yi, like rice paper infected with cinnabar, and the red slowly moistened on her face.

Zhang Yi didn't expect this little girl to blush so much, and she couldn't tease her anymore, "You take the time to read this book, there is it on the shelf, and when you go back to do the experiment, I will analyze the mechanism knowledge involved for you again." ”

Reaction Mechanism of Mineral Ions, Science Press, Lu Guangji.

The row of words written on the note of dragons flying and phoenixes dancing, Xia Jingyan carefully studied it for a long time and finally understood it, which made Zhang Yi's old face darken.

"Thank you, I'll go borrow the book later. Xia Jingyan neatly folded the note, carefully sandwiched it in the book, and then stretched out her little hand towards Zhang Yi and said: "Zhang Yi, in the future, we will be considered comrades-in-arms who will work together, let's cooperate happily." ”

Zhang Yi looked at Xia Jingyan's outstretched little hand blankly, a little confused, thinking about how many years he hadn't shaken hands with a girl, he was a little blushing for a while, but his face was black, and he didn't know if it would be seen, in order to hide his embarrassment, he also reached out and shook Xia Jingyan, and immediately smiled: "Aha, you're welcome, everyone helps each other." ”

Although it was only lightly touched, Zhang Yi could still feel that Xia Jingyan's little hands were as soft as boneless, and his skin was delicate and smooth. No wonder so many boys chase her, this is indeed a bit lethal.

Zhang Yi calmed down, and originally wanted to continue reading for a while, but now that Xia Jingyan was here, he felt a little embarrassed, obviously they were not familiar enough to stay at the same table and study.

Still, let's get out of the way.

Although it was a bit of a gray feeling, he really couldn't learn it here.

"That, classmate Xia, I have to leave first, if you have any questions, you can ask me when you get to the laboratory. Zhang Yi stood up and said hello to Xia Jingyan.

"Okay, thank you this time, classmate Zhang!" Xia Jingyan replied with a smile, just now Zhang Yi called her like that, and Xia Jingyan also learned from Zhang Yi to call him that.

"You're welcome, as it should be. After arranging all the books on the table, taking the notebook and pen, Zhang Yi left the fifth floor of the library quickly.
