Compulsory course learning and work in scientific research laboratories fill Xia Yu's daily life. When I was resting, I went on a date with Yao Min, and the days were promising. After all, that man doesn't have any expectations for his other half!

Half a year has passed in a flash, and because Xia Yu helped in Zhao Jianguo's laboratory, he didn't rest during the winter vacation, and only gave Xia Yu a seven-day holiday during the Lunar New Year, and humanitarianly asked him to go back to see his relatives.

Except for Xia's mother, who complained a few words, his father was very cheerful and explained that men should be busy. People who spend all day leisurely are a waste of time.

Dekong hurriedly saved with Yao Min for two days, and before he and his classmates in high school had enough of the cow, they flew back to the magic capital. Although life is fulfilling, Xia Yu also feels that he is becoming more and more alienated and alienated from his previous life. "Maybe that's just growth." Xia Yu comforted himself.

The National Defense University opened again during the winter break. The sound of reading can be heard everywhere, but everyone knows that various experiments are being carried out in a secret base underground.

Metal material strength refers to the ability of a material to resist deformation and destruction under the action of external forces. The main indicators are tensile strength, compressive strength, flexural strength, torsional strength and shear strength.

Alloy materials are generally obtained by two or more materials using a certain metallurgical process, and their strength index after "mixing" is higher than that of a single material before "mixing".

Mechanical strength includes other concepts such as stiffness, in addition to the above-mentioned indicators of material strength. The main hardness alloy in the world today is titanium alloy. These include tungsten, cobalt, titanium and other alloys, which are widely used in aviation, aerospace, warships, submarines and other high-tech places.

This time, the material requirements undertaken by Zhao Jianguo are higher than those of titanium alloy, and they are designated for use as cold weapons. Therefore, space metals, including some rare metals and some meteorites, are also allowed to be tested.

After several months of work, Xia Yu and the staff of the laboratory also became acquainted, especially with Zhao Jianguo. Of course, only Xia Yu calls this relationship intimacy.

The problem is that since the progress of the test was asked to speed up, Zhao Jianguo has also begun to be busy day and night. Xia Yu originally wanted to take advantage of the relationship of working together to ask Zhao Jianguo to have a light meal or something outside, but the busy Zhao Jianguo refused.

"It's not okay to go on like this, my mentor's relationship is becoming more and more collaborative, which is not a good sign." After lunch, Xia Yu lay on the table in the laboratory, holding his chin with one hand, and his brows were tightly knit in thought.

"If you want to get closer, this laboratory will definitely not work, I didn't meet. No accident, don't think about heroes saving beauty, what about the soldiers of a company outside, it's not realistic to cook something delicious, the food in this laboratory is absolutely first-class. This instructor is still a workaholic, and he doesn't talk about anything else when he works, so it seems that the only way to speed up the end of this experiment is to do it, or I don't have any chance! Hey, it's a hard life! ”

"Hey, what do you want, so focused?" A voice woke Xia Yu up, and when he turned his head, it was Zhao Jianguo who walked to the side.

"This figure, this appearance, this skin, why don't you have a chance" Xia Yu looked at Zhao Jianguo, and his brows locked even heavier.

"Xia Yu, what's wrong with you? Is it because you are not feeling well?" Zhao Jianguo asked with concern.

"Oh, no, no, I'm just a little bit angry." Xia Yu reacted and quickly explained.

"What's the fire, what's going on at home? This time I have wronged you, the winter vacation is just a few days off! Zhao Jianguo was also a little embarrassed.

"No, it's a matter of testing, I'm in a hurry and the experiment hasn't progressed?" Xia Yu began to break around

"Hehe, don't worry about this, scientific experiments are like this, we need to continue to discover, explore, think, and confirm step by step, there is no point in worrying, so we can only use more time to experiment, to try, in order to achieve our goal." Zhao Jianguo patiently explained.

"You're right, but if our footprints are wrong, aren't we going farther and farther?"

"Xia Yu, what do you mean by that?" Zhao Jianguo heard that Xia Yu had something to say.

"I said instructor, I'll talk about it casually, don't be angry! Let's talk about it first! Xia Yu tried first.

"Don't go around the bend with me, just say it, I can still be angry with you?" ，

"Okay, then I'll talk about it." Xia Yu began to narrate

"Take yesterday's test, according to the established process, it is No. 9, No. 15, No. 18 metal fusion, it seems that the temperature has reached the standard, but in fact, the molecular activity of No. 9 is not enough at all, so it is not the best effect of this alloy at all, there are 1028 tests, the five metal parameters are very good-looking, but the test only reached the level of mixing, and the molecular degree is not soluble at all, which obviously requires other catalysts, isn't it a waste of time to fool around?"

"It's not Xia Yu, are you joking with me?" Zhao Jianguo looked at Xia Yu with a little puzzlement.

"I'm talking about Instructor Zhao. You look at me as a joke! Xia Yu looked embarrassed.

"Well, let me ask you, how do you determine the activity of molecules, and how do you see that 1028 material is insoluble, the data of each of our materials are measured by precise experiments, and the phenomena and data observed by the test are supported by data. What you say is simply ridiculous and contrary to scientific foundations! "Zhao Jianguo is also very serious compared to the truth.

"Look. Director Zhao, I said don't be angry! ”

"Okay, then you give me an explanation" Zhao Jianguo looked at Xia Yu with an innocent face, calmed down, and was ready to give Xia Yu a chance, if he talked nonsense again, then he might have to let Xia Yu leave the project.

"That's right, my family is a Kunyu family, you know, so the people of my family have begun to exercise their eyesight since they were young, because broken jade, distinguishing jade is the ability to eat, and now science and technology are so developed, and a lot of equipment has been invented, but it has not replaced our eyes, because there are some things that can be determined not so simple." Xia Yu began to explain.

"I know and don't doubt what you're saying, but what does this have to do with the test!" Zhao Jianguo asked.

"Let's take this test as an example," Xia Yu casually took out a test record from the table and continued.

"In your eyes, the experiment is complete, but in my eyes, the properties of some materials are not being brought into play at all."

"You go on, I'm going to hear why." Zhao Jianguo glanced at the test number, and knew in his heart that it was the metal ratio,

"The melting point of class B metals is higher, 2200 degrees, and there is a greening performance when it melts, it stands to reason that this test should be no problem to complete according to 2300 degrees, and the material also has a greening performance, but in fact it is not reached at all, it should be a material A that has affected it, so the B material seems to be melting, but the molecular activity is not enough at all."

"Very well, then let me ask you, how do you confirm it, is your eye a microscope?" Zhao Jianguo said the main point.

"My eyes are not microscopes, but I can see the difference, you look at this, can you see the difference?" Xia Yu got up and pulled up two photos from the computer.

Zhao Jianguo glanced at it and said.

"This is a melting color map of material B, the first one is a 2200-degree color, and the second chapter is a 2300-degree color with colorless A substance added, and there is no difference in color." Zhao Jianguo is worthy of being a workaholic, and all the data he handles is meticulous.

"No, there's a difference!" Xia Yu felt that the time had come to pretend to be a cow. Stood up, put his hands behind his back, and looked out the window to start the pretend X show.

"It feels the same in the eyes of you mortals, but it is different in my eyes, the color of the first photo is noticeably oilier and more moist. And this is just a photo, the on-site observation is more obvious, that is because the material in the first photo has been completely dissolved, and the material in the second photo is obviously not to the degree, although the temperature is higher, but it may be affected by material A, but it does not achieve the effect. After Xia Yu finished speaking, he didn't care about Zhao Jianguo's doubts, he still looked outside and didn't understand.

On the other hand, Zhao Jianguo looked at the two photos carefully, and then pulled up other photos from the computer, and said with a frown: "Why, I still can't see the difference!" Is there really a difference? ”

Xia Yu turned around and looked at Zhao Jianguo.

"Some unique luster and texture are not something that can be summarized or even up to standard by the color you see, so I said that your test is not right, or at least not detailed enough."

"Like, it makes sense, but it doesn't convince me." Zhao Jianguo still didn't believe it, but he was also a little skeptical.

"Let's not fight, let's repeat this test in the afternoon, adjust the temperature to 3000, and we will talk about the results." Xia Yu is also very tough.

"Okay, I'll just go to the end with you today" Zhao Zhigang slapped the table and stood up.

This is, Zhao Siwei also came in, and was startled when he saw the picture of his sister slapping the table and getting up, where had he ever seen his sister so serious, and he seemed to be a little angry.

"Sister, what's wrong, did Xia Yu make you angry!"

"No, don't ask, get ready to start experimenting." Zhao Jianguo's expression was solemn.

"Isn't today's trial over? The next trial will take a long time, doesn't it mean to do it tomorrow? Zhao asked puzzled

"1007 trials repeated in the afternoon." Zhao Jianguo explained

"Repeat the trial, is there something going on? You must know that repeated experiments will not be done unless there are new discoveries or trials and errors," Zhao Siwei thought in his heart, but he didn't dare to ask more questions looking at the expressions of the two. Prepare things honestly.

At the beginning of the experiment, material B was heated to 2300 degrees for the first time, and the material melted and turned green. Material A was then added, and after a while, material A also melted, and then the two metals began to dissolve. Normally, this is the end of the trial. But today Xia Yu began to shout

"Look, look, the gloss has dropped significantly, and it is not moisturized, obviously the activity is not enough."

Zhao Jianguo didn't speak, still frowning, because of this actual test, Zhao Jianguo still didn't see the kind of change that Xia Yu said. But Zhao Siwei spoke.

"Xia Yu, what are you talking nonsense, nothing has changed, it should be condensed normally, and then the test will be over."

"Mortals, don't speak, watch." Xia Yu ignored Zhao Siwei, turned his head to Zhao Jianguo and said.

"Continue to heat up, first to 3000 degrees."

Zhao Jianguo didn't reply, he came directly to the instrument and began to operate the heating.

Zhao Siwei looked at the strange two, didn't know what was going on, and retreated directly to the side.

The high temperature of 3,000 degrees lasted for about half an hour, but Xia Yu, who had been staring at the container, began to speak

"It's changed, it's changed, the luminosity is there, and the color is more moist, if the temperature is higher, the effect should be better, but don't use it, just condense it." Xia Yu waved his hand.

Zhao Jianguo didn't speak, and then went to operate the machine. I was also very unhappy in my heart. But the reason for the displeasure was not Xia Yu, but the so-called light and run that Xia Yu said, and he didn't see it at all. Is his own high-achieving student a waste?

Zhao Siwei next to him didn't know what the two of them were thinking, but they saw that as soon as Xia Yu spoke, his sister worked. As soon as Xia Yu waved his hand, his sister went to work. It's fun,

After a while, after the condensation of the materials was completed, Zhao Jianguo directly handed over the materials to Zhao Siwei

"Take it for inspection, put it in the highest priority, and we will wait for the results directly."

Zhao Siwei obediently took the material and ran out.

There were only two people left in the room, Xia Yu and Zhao Jianguo, Xia Yu felt that what he said today seemed to be a bit heavy, and hurriedly offered his courtesy to Zhao Jianguo.

"Director Zhao, drink some water, you've been busy for a long time."

"Sister Zhao, you can say something, isn't it possible for my brother to be wrong?"

"Mother Zhao, why don't you scold me, I shouldn't be guilty today"

"Grandma Zhao, I was really wrong, don't ignore me, or I'll kneel down for you!"

Poof, Zhao Jianguo laughed, Xia Yu was stunned at first, after all, Zhao Jianguo rarely laughs, and he is very beautiful when he laughs. Just like the plum blossoms in the cold winter, they are amazing everywhere. Then hurry up and climb the pole.

"My sister looks so good when she smiles!"

"Don't be poor, I'm not aiming at you, let's take a break, see if you're in a hurry, and I'm talking about it when the results come out." Zhao Jianguo also sat down.

Xia Yu was serving tea and water next to him, shushing the cold and asking for warmth, as if he had forgotten all the conversation between the two of them just now.

After a long time, Zhao Siwei came back with a measurement result, Zhao Jianguo snatched it up, and after looking at the data on it, he sat down on the chair with a dull gaze.

"Sister, what's wrong with you, don't scare me!" Zhao Siwei shouted

"Sister, what's wrong with you, don't scare me!" Xia Yu shouted.
