"Mr. Li, Dopp Jin Chengxiang is normal, but the frequency of the ultrasonic echo is not equal, what is the reason for this!"

"What type?"

"Furnace tank, forty high, sixteen bottom diameter, twenty-four abdominal diameter, tire thickness 0.5, foot thickness five centimeters."

"Are there any traces of mold splicing?"

"Nope!"

"Have you ever had an X-ray?"

"I have done it, and the thickness of the carcass is basically uniform."

Li Ding'an thought for a while: "Thin tires, large instruments, it is impossible to form them at one time, it should still be mold clamping, but it is not a common segmented pulling embryo up and down docking, nor is it a flat seam, nor is it a bottom joint, but a socket ...... It's like a water pipe, a big pipe sleeve and a small pipe......"

Fingers shook two circles, Li Dingan gestured,

"Then the edges are trimmed, so you can't find any traces. However, because it is made in batches, the upper and lower sections are dry and wet when entering the furnace, and the glass and metal composition of different parts will change differently at high temperatures, which will then lead to differences in echo frequency...... If you do a fine inspection, such as X-ray characteristics of various parts and energy dispersive fluorescence analysis, you should find ......"

"Alas, thank you, Mr. Li......"

"Mr. Li, we found a piece of kiln porcelain, but we don't know the reason for its formation!"

Li Dingan was stunned for a moment: What is it?

He pulled the things back from XJ, and he has seen every single one, why didn't he find that there are such good things in it?

"What is it?"

"A piece of the mouth plate!"

The team leader beckoned, and the team members hurriedly brought the specimens.

Not big, half a foot square, the four corners are painted with the pattern of red fish playing lotus, the center of the plate is reflected in the red sun, red and bright.

Li Ding'an looked at it for a long time, but he didn't find any signs of kiln changes.

The team leader took the plate again, and turned it a little sideways, Li Dingan subconsciously squinted his eyes.

There is a lotus flower in the corner of the plate, and there is a red carp at the bottom of the point, and the fish mouth is half open under the tail, as if it wants to eat the flowers and leaves.

The angle was wrong just now, but when I look at it now, the fish's mouth is actually glowing, or is it golden?

It felt like I had a jewel in my mouth.

Surprised?

Li Ding'an pondered for a moment, and said "ha", "The paint is fried!" ”

Research was stunned for a moment: "Huh? ”

"It should be that the sagger of the porcelain fetus when it was put into the furnace broke a crack, and the fire drilled in through the gap, and the phenomenon produced after the sudden heat of the pigment: the main ingredients of the red pigment in the ancient northern region are realgar and lead dan, and sometimes a little liu sulphur will be added, and lead dan will turn yellow when exposed to open flames, and liu sulphur will burn, thus forming a yellow splash line......

However, it is not much, and then the glaze crystals and is covered by a vitreous layer, so it is not obvious. It is indeed a kiln realization, but it is not impossible to reproduce...... You can do a non-metallic element determination again to see if there is any arsenic ingredient......"

Realgar will also react when it encounters open flames, and it will be converted into arsenic, and with this thing, it means that the sagger is indeed broken......

"It's that simple?"

The team leader slapped his palms and ran away.

Another group came over: "Mr. Li, our group is responsible for the research of the ingredients of coloring and decorative lines...... During the experiment, it was found that the cobalt material of one of the specimens was very strange: iron is higher than manganese, manganese is higher than cobalt, cobalt is higher than arsenic, arsenic is higher than copper, copper is higher than zinc, and zinc is higher than nickel......"

He Anbang was stunned for a moment: "Iron, manganese, cobalt, arsenic, copper, zinc, nickel? ”

"Yes, seven!"

It's weird.

Whether it is Zeng Qing, Hui Qing, Bian Qing, Su Ma Liqing, or Zhejiang material, Zhu Ming material, no matter which dynasty and which period, green material is divided into three categories: low manganese, high manganese, and high-speed rail.

The first two are domestically produced: low-manganese materials do not contain arsenic and zinc, high-manganese materials do not contain copper and zinc, and the last one is imported from Central Asia, which is the so-called huiqing, which does not contain copper and nickel.

Therefore, it is rare to see more than six elements, and it is really the first time to hear it, and all seven elements are alive?

He Anbang looked at Ma Xianming, and Ma Xianming also shook his head: After Li Dingan became the shopkeeper, he was in charge of the project, and of course he knew what problems each group had.

But to be honest, he didn't get it either.

"How many?"

"Just one piece, an amphora."

"What about hair color?"

"It is more colorful, better than domestic materials and recycled materials!"

"Has the mixing ratio been done?"

"I did, but no matter how I matched it, I couldn't restore the same order of elements."

"Are there any characteristics of microscopic phasing?"

"Yes, there are subtle rust scars!"

"Red?"

"It's not red, it's dark yellow!"

Dull yellow?

Li Ding'an frowned, thought for a while, and his eyes lit up: "Have you done laser light source fluorescence measurement and mass-charge inductively coupled plasma constitution detection?" ”

"What?"

He knew about spectroscopy, measured radiation rays, but he had never heard of the latter kind.

The team leader shook his head: "No! ”

He Anbang has never heard of it: "We have such an instrument? ”

"Yes, analyze the composition and content of radioactive elements!" Ma Xianming nodded, "But it's never used!" ”

"Does that mean there are other radioactive elements besides cobalt?"

"I'm not sure, just do it!"

Li Ding'an thought for a moment: "There is a cobalt mine of arsenic cobalt in Katanga Province, which has more than a dozen associated elements, including these seven. But this cobalt mine was only discovered during the First World War, and it is certainly not this cobalt material used in Mongolian porcelain......"

"In addition, there is a cobalt mine rich in copper, nickel and iron in the Lisakovsk region of central Siberia in Russia, which is very similar to China's high-manganese material, but does not contain arsenic...... This discovery was made relatively early, and it is also close to Inner Mongolia, so I suspect that when the master of Huacai mixed the green material, he used a part of the low-manganese material and mixed this kind of ......"

"But what does it have to do with radioactive elements?"

"The mine's soil has a characteristic of uranium, and uranium decay affects other elements...... And when Team Leader Wei made the ratio, he used ordinary green materials, of course, there was no way to restore the order of the elements......"

"The thing that made the atomic bomb?"

"Before the atomic bomb was built, the main use of this thing was to mix paint...... Blue, green, yellow! ”

Isn't green material blue and green?

And the microscopic phase of this thing happens to have yellow lines?

Wrong......

He Anbang was excited: "Radioactive? ”

"Rest assured, the concentration is very low, it should be less than one thousandth, and it is only an ore component, the radiation penetration is not strong, and the radiation intensity is about equal to the common colored glass ...... containing uranium."

"That's good!"

The members of the visiting group also breathed a sigh of relief and became more curious: the questions were getting deeper and deeper.

Studying porcelain, can it involve radioactive metals?

The key is, can Li Dingan still answer?

I don't know if it's right......

Director Fu smiled: "Do you know a lot?" ”

The curator nodded: "Otherwise, it won't be his turn to be in charge......"

While speaking, Yao Chuan ran back happily: "Teacher Li, that's right!" ”

"Be detailed!"

"Haha...... Lao Cheng lowered the air pressure to 0.8, and a single value in the chromatography is correct! ”

"Glaze crystallization!"

"I haven't had time to measure it yet, but recalculated, it's completely feasible to drop the furnace temperature to 500 degrees."

"If you can......

As soon as the words fell, the second group also ran back: "Mr. Li, there are results: the vitrification degree of the tank is different from the top and bottom, inside and outside, the upper half of the strength is high, and the lower half of the strength is ...... poor."

"What about the elastic modulus cardinality?"

"Quite the opposite, high and low!"

"Well, clamping splicing, socketing!"

"Right...... Thank you, Mr. Li! ”

"As it should be!"

Li Dingan is very calm.

Because this is a new process and new technology, there are many difficulties and problems that have been discovered. In the first month of the project, it was basically like this every day, and Li Dingan had no idle time, whether it was his hands or mouth, or even the system.

Li Ding'an's busy feet did not touch the ground, eating was measured in seconds, and the habit of sprinting 100 meters to the toilet was developed at that time, and then in order to save time, he simply moved the office to the next door of the research room.

Including experience and knowledge, it is also accumulated at this time.

The dependence of the researchers was also cultivated at that time: if they found a problem that they did not understand in the research, they would always seek out Mr. Li. No matter how difficult it is, he can ensure that you can analyze it clearly and clearly from the cause to the process and then to the result.

So from He Anbang to the researchers, they are very calm, because they have long been accustomed to it.

But the members of the delegation were a little uneasy.

At first glance, both questions are uncomplicated and can be understood by non-specialists:

The first is the physical changes caused by altitude and air pressure, which is easy to verify, and it only takes about 20 minutes from the test to the result.

There are also echo frequencies that are unequal, this is simpler, it is caused by porcelain splicing, and the verification is simpler: from the mention of solving, it will take more than ten minutes.

But this is to infer the cause from the effect, of course, simple.

Because there are many reasons for these two problems, air pressure and splicing are just one of the many causes, and they are extremely inconspicuous.

It's like buying a lottery ticket, just about 30 numbers, how simple it is, but there are millions of combinations, can you know which group is drawn?

It can also be seen from this that it is not for nothing that such a young person can become the general manager of the project......

was sighing, and the third group also came:

"Mr. Li, it has been measured, and there is arsenic on the glaze of the specimen!"

"So fast?"

"There are test strips in the laboratory, and I did a toxicity test!"

Li Dingan was stunned for a moment: This thing is a standard material for a laboratory first-aid kit, and he forgot about it for a while.

Since there is arsenic, it means that there is an open flame, so it can be determined that the light in the fish's mouth is the kiln change phenomenon caused by the destruction of the sagger.

Li Dingan nodded: "Just measure it out......"

As soon as the words fell, Team Leader Wei also came, but he didn't look very good-looking: "Mr. Li, there is uranium in the cobalt material!" ”

Li Ding'an sighed in his heart: "The concentration is very high? ”

"Not high, 0.7 per thousand!"

"Very radioactive?"

"It's not strong, the ray penetration is very weak!"

Team Leader Wei sighed, "I just thought, why didn't I think about analyzing the types of rays before?" ”

"It's normal...... Li Ding'an smiled, "It's just porcelain, and it's not nuclear research?" ”

Because no one would have thought that there was uranium in porcelain?

Li Dingan raised his hand again: "Is there anything else?" ”

asked a few more questions, basically all of them were dark under the lamp, Li Ding'an answered them one by one, quickly and accurately, and the atmosphere in the laboratory was very warm.

It's also a little weird.

The group leaders and researchers were excited: none of the problems were big, but they were slowing down. Some may be solved in three or five days, and they will compete with tires, such as color difference.

Some may take a week or two, such as kiln changes, and some will drag longer, such as uranium.

But as soon as Li Ding'an came, the problem would not be a problem, and it would be solved in minutes.

What's the time you save for what's not good?

Eating, drinking, sleeping...... It's also brain-saving.

The visiting group was very silent: how much does this understand?

The first problem is chromatic aberration, and the second problem is furnace temperature and release crystallization temperature, both of which are caused by different altitudes, involving atmosphere, geography, chemical pigment engineering, and so on.

Then there is the porcelain splicing, which belongs to the field of ceramics, but also involves metallurgy and heat treatment, as well as some ultrasonic and materials theory.

Then there is the kiln change, which is pure chemistry.

Then there is cobalt, which in turn involves radioactive metals.

and the last two mines...... It is better to be a foreign geography......

The questions are very complex, and the disciplines involved are varied, but they are not profound, and college students who study related majors can understand it.

But if you change to a person who knows so many majors and disciplines, it is impossible for people to understand: there is a specialization in the art industry, and you are not allowed to attack it all.

And even if you understand everything, you may not be able to solve it: for example, Ma Xianming, Deputy Director Zhang, as well as Team Leader Yao, Team Leader Wei, Cheng Yongquan, all well-known experts, authoritative in the industry, profound knowledge, and rich experience.

If these people add a piece, they must know more than Li Dingan. But they can't choose the most correct option from the many to countless possibilities in a short period of time, so they can only try and make mistakes over and over again.

Therefore, it is not only necessary to understand more, but also to have the ability to see the essence through the phenomenon. Just like Li Ding'an, you don't need to look at the experimental report, you don't need to look at the calculation data, just through a few key information, you can analyze the most accurate results.

The more knowledgeable you are, the more you understand the difficulty of this: it is impossible to do this without thousands of experiments and experience.

It's even more impossible to be so fast: Yao Chuan said that he only needed a few minutes for a question, and he really only used a few minutes.

Look at the age again...... No way!

This is the most surprising thing for the participants......

As the minutes ticked by, fewer and fewer people asked questions.

If the problem is solved, of course, there is no need to argue, there is no need to argue, and the results can be verified.

So, it's getting quieter and quieter in the lab.

Li Dingan also breathed a sigh of relief, fortunately, he didn't pull his crotch, and he coped with it.

Otherwise, He Anbang can kill him: the visiting group has entered the research room, but you, the person in charge, are sleeping?

Looking at it again, Lao He's tooth roots are about to come out, and he gave Li Dingan a thumbs up.

Needless to guess, the visiting group must be very satisfied: where can they find such a comprehensive and professional project leader?

It can be seen that the professionalism and research ability of the research team are ......

Just as he was happy, someone asked coldly: "In addition to cobalt oxide, what other rare elements are in porcelain?" ”

Layman, right?

Certainly not researchers, because they all know ......

He Anbang glanced at it subconsciously, and straightened his face again: "Why are you stunned, answer the question!" ”

"Oh...... What about me? ”

"Nonsense!"

Li Dingan took a look: he is a middle-aged man, standing next to the curator, and his rank is estimated to be not low.

He should be about the same age as his father, quite tall, thin, and quite handsome.

But I don't know if it's an illusion, it feels a little familiar.

The curator and secretary both looked at him, and Li Ding'an didn't have time to think about it: "In addition to cobalt, there are only titanium, zirconium, barium and other elements in traditional porcelain, which are mainly used as coagulants, brighteners or matting agents, and the use of porcelain is mainly for furnishings......"

"What about modern porcelain?"

"A lot, but it's mostly used for industrial porcelain!"

"Be specific!"

"Oxides include yttrium oxide, zirconia, thorium oxide, beryllium oxide, gadolinium oxide, fluoride barium fluoride, calcium fluoride, magnesium fluoride, nitride aluminum nitride, aluminum magnesium and so on...... Mostly used in superconductivity, dielectric, electro-optical, pressure-sensitive, laser ......"

"Specific industries!"

"Automotive, Shipbuilding, Precision Machinery, Medicine, Aerospace, and even Defense and Military ......"

"How many types of military ones are there?"

"There are also a lot, laser media, armor protection, window translucency, as well as infrared detection, laser guidance, 、......"

Just talking about "infrared detection" and "laser guidance", Li Dingan was taken aback.

He finally knew what the group was here for today.

Light porcelain, mirror light porcelain!
