Chapter 31 I'm leaving now!
The sun was just beginning to set in the west, and the clock pointed to five o'clock.
With a creak, the laboratory door opened, and Lin Sicheng walked in.
Feng Lin and Xu Bo subconsciously looked up.
Isn't this the student I ran into at the restaurant this morning?
Xu Bo frowned: "Who let you in? Get out!"
Lin Sicheng was stunned for a moment: No, are you fucking on drugs?
Wang Qizhi followed closely behind Qi, carrying the iron certificate in his hand.
He glanced at it and said, "Xiao Xu, you can go home first!"
"Ah, Professor Wang? I'm sorry, I didn't know it was you..."
"Let's go home!"
Wang Qizhi's expression was somewhat serious, and Xu Bo dared not argue any further, so he took off his gloves.
As soon as the person left, Wang Qizhi looked at Feng Lin and asked, "How did you recruit these people?"
Feng Lin lowered her head: "Professor Wang, I'm sorry!"
She never expected Xu Bo to be so jealous.
No mentor would like a personality like that, because no one wants a second Zhu Ling in their lab.
"Professor Wang, I will go to the teaching and research center tomorrow to re-coordinate!"
"Hmm!" Wang Qizhi's expression softened a bit. He put down the iron tile and beckoned, "Come here!"
Come on, come on.
Lin Sicheng took off his coat, put on a protective suit, and entered the infrared reflection imaging room.
Feng Lin was startled.
The equipment inside costs several million, and even Xu Bo isn't usually allowed to touch it; at most, he can just dust it off.
She hurried over: "Lin, do you need any help?"
"Ignore him!" Wang Qizhi waved his hand. "You take notes!"
With her supervisor making these arrangements, Feng Lin dared not say anything and obediently took the folder and pulled out the forms.
But I was really worried, so I kept my eyes glued to the monitor.
After turning on the machine to preheat it, Lin Sicheng casually tossed the iron plate into the refrigerator and began setting the parameters.
"Emissivity 0.07!"
"Blackbody source calibration: humidity 10~40HR, temperature difference -20℃ to 150℃."
"Pseudo-Rainbow Mapping: Iron Red Mode!"
Feng Lin suddenly raised her head and stared at Wang Qizhi: No... he actually knows?
Emissivity aside, what would a graduate student who isn't involved in cultural heritage preservation know about black source calibration and pseudo-rainbow mapping?
Forget about adjusting parameters, I don't understand those two words at all.
Wang Qizhi tapped the table: "Why are you looking at me? To take notes?"
"Oh, oh~"
She lowered her head, glanced at the monitor, and quickly copied it down.
Wang Zhiqi was also puzzled.
Lin Sicheng mentioned that he had gone into the laboratory with Professor Lin more than once. Moreover, he explained things very clearly, and he certainly understood the basic operating procedures of the instruments.
Otherwise, Wang Qizhi wouldn't have let him into the equipment room.
What Wang Qizhi found strange was Lin Sicheng's casualness, relaxed demeanor, and sense of familiarity.
He doesn't even need to turn his head to know where the dashboard is, where the tray is, and where the light source and sensor are.
With just a glance, you can tell how much the angles differ and how to adjust them.
It's impossible to be this proficient without having been in a laboratory hundreds or thousands of times.
Even without comparing him to others, Feng Lin next to him seems inferior.
No, it should be much worse; this kid has already started testing.
Multi-point scanning, dynamic monitoring...
Image animation, annotation, matrix data export...
Heat map overlay, precise defect location...
Linear temperature difference as a marker, analysis...
Wang Qizhi stared in disbelief.
As the saying goes, different professions are like different worlds. Even among metal artifacts, the restoration of bronze and iron artifacts are worlds apart, let alone ceramics.
Don't assume that the same testing instrument is being used, as the operating procedures and required conditions are vastly different.
Therefore, Wang Qizhi was prepared to provide guidance at any time.
But before he could give any pointers, Lin Sicheng had already completed most of the testing.
Wait, something's not right... Why does the exported image look so strange?
Wang Qizhi blinked: "Surface penetration imaging of iron artifacts... wait, where did he learn that?"
Feng Lin, standing next to her, stared wide-eyed.
It's no exaggeration to say that Lin Sicheng is doing something she really doesn't know how to do: combining iron artifacts with imaging. This instrument does have this function, but she has never learned how to do it.
To be more precise: Xida University doesn't teach that.
Only one institution in the country offers related courses: Peking University's Cultural Heritage and Museology program.
Moreover, only graduate students specializing in the preservation of iron artifacts will study this course...
As the two were still stunned, Lin Sicheng's voice came through the microphone: "Record it!"
"Surface rust components: FeO, FeO..."
"Middle and bottom layers: α-FeOOH, β-FeOOH, γ-FeOOH..."
"Hydroxides: Fe(OH), Fe(OH)... Chloride ions: FeCl, FeCl..."
"Sulfates: FeSO₄... Carbonates: such as FePO₄..."
Feng Lin was completely confused. She picked up a pen, but couldn't remember anything.
Finished?
This was Lin Sicheng's deduction based on eye measurements; it wasn't displayed on the instrument at all.
The problem is that she was distracted for a moment and didn't remember any of them.
Just as he was wondering what to do, Lin Sicheng carried the iron plate out of the imaging room.
Wang Qizhi asked with a suspicious look, "Where did you learn about penetrating imaging?"
"In the book!"
What is that?
"In that book?"
Lin Sicheng slowly took off his protective suit:
"Institute of Archaeology, Chinese Academy of Social Sciences, *Acta Archaeologica Sinica*, No. 8, 2006."
"Chinese Academy of Social Sciences, Archaeology, Issue 11, 2006."
"Peking University Cultural Heritage and Museology, *Archaeological Research*, Issue 6, 2006!"
Wang Qizhi's eyes widened: "Lin Sicheng, what nonsense are you spouting?"
Lin Sicheng sighed inwardly: It wasn't utter nonsense, but it was certainly a bit perfunctory.
But we can't just keep it hidden and not use it, can we?
That's just asking for trouble when you don't have any.
Besides, it's not some top-secret technology.
Lin Sicheng put down the iron certificate, put on gloves and a mask, and began to prepare the medicine: "Professor Wang, I really didn't lie to you, you can check if you don't believe me!"
Wang Qizhi's lips moved, and the words of cursing welled up in his throat.
Is this a question of whether or not to check the journal, and whether or not to verify if there are relevant papers in the journal?
According to Lin Sicheng's logic, if one could learn the most advanced scientific testing knowledge simply by flipping through a journal or glancing at a paper, wouldn't scientists be everywhere?
But on the other hand: Peking University is the only university in the country that teaches related technologies. If he didn't learn it from books, where else could he have learned it?
Just as he was secretly guessing, a few pungent smells wafted over, and Wang Qizhi squinted his eyes:
Lin Sicheng was mixing together a bunch of bottles and jars. Oxalic acid, acetate, citric acid, hydrochloric acid...
Wang Qizhi's eyelids twitched: "What are you doing?"
Lin Sicheng replied matter-of-factly, "Removing rust?"
"No... why not use ultrasound if we have it?"
"Too slow, and you still have to wash it in the end!"
"Then why not use tea? Electrolyte would also work."
"It's better to do it all at once than to do it many times!"
Wash it, dry it, wash it again, but it still can't be dried.
By the time the washing was finished, the electric kiln had already arrived.
"One-step solution my ass!"
Even though it's true that every profession has its own expertise, how could Wang Qizhi not understand the harm that acid can cause to metal artifacts?
And right in front of him, in his laboratory?
What's this?
This is a blatant insult to a cultural relics conservation researcher.
Wang Qizhi was so angry his liver hurt. He grabbed Lin Sicheng and pulled him up, yelling, "Get up!"
Lin Sicheng was both amused and exasperated: "Professor Wang, I'm really short of money, and I need it urgently!"
Wang Qizhi was stunned for a moment, then gritted his teeth and said, "Five hundred thousand!"
"What?"
"Five hundred thousand, I'll transfer it to your card later!" Wang Qizhi said, pointing to the door with a dark face. "Now get out of here!"
Haha, how much?
Lin Sicheng had previously thought: even if Professor Wang is knowledgeable, it would only cost 300,000 at most.
The result was quite unexpected: Professor Wang got angry and the price almost doubled?
He deftly removed his gloves, grinned broadly, and shrugged: "Alright, Professor Wang, I'm off!"
