The special project of the duo of Blue Feather and Ivan is based on experiments.

It is a science of discovery and change, which studies the composition, structure, properties, and laws of change of certain substances.

The significance of this experiment lies in the understanding and use of such cosmic matter, the induction and formulation of the main methods and means to transform such material world, and the promotion of its interpenetration with disciplines.

If we take the results of similar research projects as an example, our predecessors have already obtained the law of element distribution through the analysis of the chemical composition of various stars, and discovered the existence of simple compounds in interstellar space, which has provided experimental data for the study of the evolution process of celestial bodies and modern cosmology.

This kind of research, while further enriching the content of the dialectics of nature, also proves that it is very closely related to human progress and social development, and the reason why its achievements are not only an important symbol of social civilization, but also an important reason why certain powers create wars of aggression for the sake of plunder.

Therefore, in order to meet the security needs of the country's national land resources, it is necessary to enhance the scientific and technological strength of national defense.

After nearly 20 years of silence, the mission of restoring and developing the continuation of China's natural science knowledge has really fallen on the shoulders of the "lucky people" of Ivan's generation. This was one of the important reasons why Ivan chose this topic, and of course, Blue Feather was also silently supporting his choice.

It's been half a month since she came back from the Great Northwest, and as long as it's self-study time, Lan Yu and Ivan rush into the library, and he leads her around the topic, collects materials in advance, and makes full preparations for formulating the experimental plan.

"The method of choosing to dissolve has been almost summed up, what about yours?" Ivan was excited, and their first collection was about to be completed in the afternoon.

"The collection of chemical solvent types has also ended, and the collection of inhibitor or accelerator types has just begun." Lan Yu felt that there was a lot of consultation, and he was a little overwhelmed.

"It's okay, then let's divide the labor, tomorrow you start to check the inhibitor, I check the accelerator."

"Okay." She was overjoyed because in the literature, these two reagents are always like sisters, most of them will appear at the same time, and they can be synchronized.

After dinner, they sorted out their notes in the reading room as usual.

Suddenly, that Alan walked up to Lan Yu and sat down, and after they nodded to each other, they began their own self-study. However, Lan Yu could tell that she had something to say to her. And Lan Yu has already guessed that she must be very curious about why Lan Yu didn't go back to her hometown during this winter vacation.

At first, Lan Yu didn't bother to talk to her, but when Alan asked Lan Yu to accompany her to relieve her, she said:

"It's okay, I should be convenient too." Blue Feather greeted Ivan and followed Alain out of the reading room.

After relieving her hand, Lan Yu was about to walk back to the reading room, but Alain pulled her to the other end of the corridor, and Alain pointed:

"Come, I'll take you somewhere, don't keep looking like a nerd." Alan was very enthusiastic, and Lan Yu thought, so he didn't hesitate to refuse her.

"Oh, it can't be too long." Lan Yu was afraid of delaying their time to sort out the information. In fact, Lan Yu can stay with Ivan for a minute now, and he doesn't want to lose and waste it. Because she knew there wasn't much time left with him.

"Hey, it's almost time to study at night, but it's still a little bit left?" Alan was dismissive, and Lan Yu didn't want to explain anything to her, so he just followed her.

"You tell me the truth, what happened to you and Ding Zhen?" She still wanted to break the casserole.

"I know you like him, so go after him boldly, I support you." Lan Yu simply reassured her to eat.

"But he said, not only does he like you, but he also said that you also like him, but there was a misunderstanding, you were angry with him, he asked me to help him make an appointment with you today, or you go and tell him now."

"Don't worry, I will."

At this time, Lan Yu felt that emotions were really troublesome, and she had been harassed repeatedly, but it was really not something she could do alone.

Now, Lan Yu has been able to determine what kind of emotional world she needs, and she has to face it calmly tonight and make her position clear to Alain.

"Let's go, I'll take you over to see Ding Zhen." So they walked together in the direction of the garden.

Tonight, this season has passed the sting, and the spring thunder can still be faintly discerned in the distance. As the agricultural proverb goes, the ground in the garden is a little soft, and the spring flowers and peach blossoms seem to be in bud. But at this time, Lan Yu had no intention of watching the warmth and coldness of the earth.

"Alas, Ding Zhen, I called Lan Yu for you, you two have a good chat." Alain finished speaking with a puff and walked away in a huff.

"How were you doing on vacation?" Lan Yu should take the lead, she asked Ding Zhen.

"It's not good, without you, our fellow party is no longer interesting. You won't go on a blind date this holiday, will you? ”

"Huh? Blind date, can't you? Lan Yu asked rhetorically.

"Don't be angry with me, I know, it must not be."

"I know you're kidding." Lan Yu was a little bored in his heart, but let's talk kindly:

"I'm going to prepare my thesis, will I be busy?" Lan Yu had been moved by him, it was the kind of unforgettable, why did he feel like a stranger now.

"Of course we are busy, our engineering department has to do projects in steel mills and mines, and you science students have to be in the laboratory, I envy it."

"Your major has decided, so you have to be in the smelting industry." Lan Yu was absent-minded.

"Yes, I'm a smelting professional."

"It's not early tonight, I want to talk to you when I have time, okay?" His words slurred and stopped.

"Yes." It seems that he doesn't want to cut into the topic today, okay, anyway, my time is very tight, so I'll talk about it later, Lan Yu thought to himself.

After saying goodbye to Ding Zhen, Lan Yu was on the way back to the reading room. From afar, she saw Ivan wandering through the door of the machine building.

Lan Yu quietly rubbed to the steps, and while he was not paying attention, he went up and covered his eyes with both hands, thinking that it would startle him, but he was not in a hurry, squatted down a little and waited for her size level, and said:

"Let me guess which daring little mouse dares to blind the eyes of an elephant."

"Well, how do you know it's me?" Lan Yu asked puzzled.

"Well, don't say it, this time, it's really me stalking you, don't mind?"

"What's that, I still want to go with you."

"Huh? Are you sure? He listened with interest to what Lan Yu said.

"Oh, let's not bother with all that, let's go back and finish today's task."

"No, I'm pretty much tidy up." This time, he worked a lot again, but Lan Yu liked the experiment report he sorted out, which was very clearly organized and time-saving to read.

"Tomorrow's collection is very important, in addition to sorting out the content of inhibitors and accelerators, but also converting the chemical phase analysis of minerals into chemical speciation analysis. Because, at present, in this regard, my country is basically in a blank stage, so it will be very time-consuming to turn over the original materials. Is that okay? ”

"Of course you can, I can't ask for it!" Lan Yu was happy.

Chemical phase analysis, also known as chemical speciation analysis in the field of environmental science, is of great significance in environmental monitoring and evaluation, as well as pollution control and treatment, and has attracted more and more attention, which is also the focus of their research group.
