"Haha, I'm amazing, what do you mean?" Zhang Yi laughed, and there seemed to be something else in his smile.

"What is it?" Xia Jingyan said suspiciously, "What I said was that your method just now really worked, I added a little more sodium hexametaphosphate and sodium silicate, and the slurry was really well dispersed." ”

"Of course, I don't see who comes up with the idea. Zhang Yi didn't forget to brag.

"Haha, you have it, but don't have your tail cocked. Xia Jingyan seemed to have finished the experiment, so she stood in front of the experimental table and watched Zhang Yi do the experiment.

The two of them seemed to have opened up the conversation, and they talked about any topic, and they came and went, and they gradually became familiar with Xia Jingyan.

Sometimes Zhang Yi suddenly came up with a few funny jokes, which made Xia Jingyan laugh and bend over.

However, although he chatted with Xia Jingyan very energetically, Zhang Yi was not idle in his hands.

The reagent that should be added, the instrument that should be adjusted, and the solution that should be prepared, this is to do his own experiment, Zhang Yi also tried his best, his hand movements flew up and down, and Xia Jingyan joked with his mouth.

This made Xia Jingyan stunned, and sometimes Zhang Yi's words didn't answer.

Watching Zhang Yi methodically do these experiments at the same time, these experiments seemed to have been operated countless times, and the time of each experiment was just right, and there was no rush at all.

Zhang Yi skillfully operated various instruments, skillfully blended all kinds of dazzling reagents, Xia Jingyan was surprised in his heart, this is a junior like himself?

Such a skilled operation should be no worse than the proficiency that can only be achieved by those full-time experimental researchers who have been repeatedly operating every day for more than ten years.

He is not only proficient in scientific research theory, but also proficient in various experimental techniques, and seems to be very disdainful of the tungsten and molybdenum separation experiments that Professor Zhong has a headache for.

She suddenly remembered that almost every time Zhang Yi saw her, he would call her "Xueba", Xia Jingyan's face suddenly turned red when she thought of this, Zhang Yi was so powerful, he actually called himself Xueba, I'm afraid he wouldn't mock her in his heart, right?

Zhang Yi was still talking, and suddenly found that Xia Jingyan didn't move, and then his face turned red, as if he had a red veil on his face, Zhang Yi said in his heart, it shouldn't be that he said something wrong.

The two of them fell silent suddenly.

Xia Jingyan suddenly felt at this moment that Zhang Yi was as unfathomable as an abyss, and it was difficult to guess how many things he had in his head, whether he had a chip in his head?

Zhang Yi is so powerful, and he is very calm during this time, and I haven't seen that he has paid attention to tungsten and molybdenum separation experiments.

She also wanted to know if Zhang Yi would be able to check the tungsten and molybdenum separation experiments day and night during this period of time, and there was still no progress?

Taking this opportunity, Xia Jingyan asked quietly beside him: "Zhang Yi, do you think the tungsten and molybdenum separation experiment done by our research group can be successful?"

"Tungsten and molybdenum separation?" Zhang Yi was stunned, but he didn't expect Xia Jingyan to be silent for a long time, so he wanted to ask this question.

After thinking about it for a while, Zhang Yi said: "In fact, tungsten and molybdenum separation is not very difficult, as long as you grasp the difference in the ionic properties of tungsten and molybdenum in the aqueous solution, it is easy to separate them. ”

The tungsten and molybdenum separation project has really stumped many scientists, the properties of the two minerals of tungsten and molybdenum are too similar, if you want to separate them and obtain one of the pure minerals separately, you must pass microscopic detection methods, according to the different properties of the two ions in the solution, and constantly adjust the results to get the results.

This project is also limited by the testing equipment, in 98 years, the related equipment is still very backward, there is a school such equipment is very precious, let alone used in the usual experiments.

Professor Zhong took this out as a temptation, and he probably didn't have much hope in his heart.

Zhang Yi said this, also because of the later development of technology, tungsten and molybdenum separation technology has been made public, Zhang Yi has also been in contact, knows where the key points are, and there is no need to do these exploration experiments.

"Don't be ashamed!"

Before Zhang Yi's words fell, a person flashed out of the door of the laboratory.

Dressed in casual clothes, with a mid-split head, and a supper in his hand, it looks like a bowl of spicy tang and a cup of milk tea.

The person who came was Li Mowen, she finally bought Xia Jingyan's roommate, and she usually gave a lot of benefits, and she sent things and invited him to dinner, so that the family agreed to provide him with Xia Jingyan's information.

Tonight, it was Xia Jingyan's roommate who secretly revealed to Li Mowen that Xia Jingyan would do experiments in the laboratory at night, and Li Mowen also hurriedly gave gifts to thank him and maintain a good relationship with others.

After buying Xia Jingyan's favorite Malatang and his favorite milk tea, Li Mowen rushed to the laboratory in a hurry.

I wanted to surprise Xia Jingyan, but by the way, I cared about it, but as soon as the big beauty was moved, I threw myself into my arms.

What he didn't expect was that the once-in-a-lifetime opportunity was actually climbed by Zhang Yijie first, and he heard Zhang Yi bragging unashamedly, which made him angry, and his tone was not good after coming in.

Seeing Li Mowen appear, Xia Jingyan reflexively leaned towards Zhang Yi's side, and it seemed that she was not less harassed by Li Dashao.

Zhang Yi didn't bother to pay attention to him, the experiment had entered the final stage, and he only needed to record the data, and he wanted to finish it early and leave quickly, so that Teacher Zhu, who was in charge of the laboratory, came to catch up again.

Li Mowen walked quickly to Xia Jingyan's side, immediately put on a smiling face, and said with a little flattery: "Xia Jingyan, I'm tired of the experiment, I bought you some supper, eat it while it's hot." ”

"No thanks, I've recently lost weight and don't eat at night. Xia Jingyan's face was flat, and she couldn't see any expression.

Li Mowen looked at Xia Jingyan's slender figure, his face was cloudy, but he still smiled very gentlemanly: "It's okay if you don't eat, it's so late, I'll send you back later......"

"No need, Zhang Yi just said that he was going to send me. Li Mowen was interrupted by Xia Jingyan before she finished speaking, she looked at Zhang Yi, her big eyes showed a look of help, for fear that Zhang Yi's refusal would make her very embarrassed.

"Yes, I'll send it. Zhang Yiben had no intention of interfering, but Li Mowen's words just now made him feel uncomfortable, chasing a girl, if you have the ability, chase it, if you don't have the ability, get out, don't mess with him if you have nothing to do.

Li Mowen's face turned pale when he heard this, his face seemed to be covered with frost, and he seemed to have been slapped hard, standing there alone, neither leaving nor staying, it was very embarrassing.

At this time, Zhang Yi's experiment was over, he cleaned up the table a little, sorted out the experimental equipment, and Xia Jingyan also helped wash the beaker.

Li Mowen was very bored if he stayed any longer, Xia Jingyan didn't pay attention to him at all, making his face very dull, and he turned around and walked out of the laboratory without saying a word.

Zhang Yi's laboratory was cleaned up, and Xia Jingyan also left the laboratory with his bag on his back, and went to Teacher Zhu to return the key together.

At this time, Teacher Zhu muttered in a low voice: "These two people, do experiments and make feelings? ”

Zhang Yi's ears were sharp, and he listened to it word for word, and then looked at Xia Jingyan, and suddenly found that she was blushing to the base of her neck, and she thought about what she had heard.

The two of them hurried and left the academy building as if they were fleeing.

Under a tree opposite the college building, looking at the backs of the two leaving, Li Mowen held the supper in his hand fiercely, the back of his hand was bruised, the cup in his hand was pinched, and the milk tea was spilled on the ground.
