I started with a ship full of max-level veterans, and I'm just a complete noob.

Late at night, in the single dormitory of the Third Electronics Factory.

Jiang Ming pushed the rusty iron latch with his other hand, pulling the blue curtains shut tightly, not letting in even a sliver of moonlight.

He didn't even take off his shoes before sitting cross-legged on the hard bed.

The table was covered with various scraps of paper brought back from the workshop.

On the left is the inventory list that Wu Hanzhang just compiled that evening.

The only thing written on it was the amount of cerium oxide in stock.

Fifty grams.

In the middle is a fragment of an experimental paper left behind when the Soviet advisors withdrew, with the cathode indicators blurred and unclear.

On the right is the 10 to the power of negative 5 Pascal vacuum data that was just measured this afternoon, as well as the minimum anti-interference frequency required by the top-secret document from the Northwest.

Looking at the fifty grams, Jiang Ming felt as if a stone was pressing down on his chest.

He understood the mature cathode formulation theories of later generations.

But he was well aware that all the theories of later generations were based on high-purity materials and mature workshop processes.

This batch of Soviet surplus goods I have now has been gathering dust in a corner for several years, and its impurity content makes it a dangerously unpredictable situation.

He wouldn't dare to simply write down a mixing ratio based on his memories from later generations.

Fifty grams of material is only enough for two or three rounds of trial and error.

If the parameters report an error even once, most of these fifty grams can be wasted.

If they make two mistakes, all the micron-level seals, manual exhaust valves, and liquid nitrogen cold traps that Workshop No. 1 has painstakingly assembled over the past two weeks will become a complete joke.

The wall clock ticked monotonously.

The moment the clock struck midnight, the bronze-colored "Records of Human Connections" deep within my mind suddenly lit up.

Today's three psychic summoning quotas have been refreshed as scheduled.

Jiang Ming immediately closed his eyes, his consciousness plummeting, and decisively locked onto the most hot-tempered early pioneer of vacuum tube and radar physics on the network map.

[System Prompt: Connecting to a late pioneer of early vacuum tube and radar physics. Duration: 15 minutes. Countdown begins.]

"Senior, I only have fifty grams of cerium oxide of unknown purity."

"I have to finalize the doping ratio of the cathode coating for the anti-interference tube in the shortest possible time; I can't afford to make a mistake."

Jiang Ming spoke rapidly, getting straight to the point.

A cold snort immediately came from the other side of the void.

"You really think rare earth elements are a magic bullet?"

The pioneer's voice was as stern as if he were reprimanding a novice.

"Adding rare earth elements is not like kneading dough to make a pancake; it's not like adding flour when there's too much water."

"You have to deal with the three mortal enemies at the same time: the work function of the material, the porosity of the coating, and the adhesion to the substrate."

"Fifty grams is indeed a desperate situation, so you can't rely on luck to gamble."

The pioneers pointed out the crux of the matter incisively.

"The only way forward is through trace doping."

"Furthermore, the sintering process must not use the barbaric method of pushing things to the top in one go, as employed by the Soviet Union."

"We must change to stepped sintering to lengthen the heating curve."

"A hydrogen-nitrogen mixture must be introduced throughout the sintering process for atmosphere protection; otherwise, your old material, which is not pure enough, will be directly oxidized into waste residue when exposed to high temperatures."

Before Jiang Ming could ask for the specific temperature values ​​for each step, the fifteen-minute countdown was reset to zero.

The connection was instantly severed.

Without pausing for a moment, Jiang Ming immediately turned his attention to the young fellow student next to him who was researching the material interface.

"Junior Jiang Ming."

"If the purity of cerium oxide is completely unknown, what would be the consequences of forcibly increasing the doping ratio to ensure emission efficiency?"

The voices of the younger disciples instantly rose, their emotions running high.

"You're asking for it!"

"Without knowing the composition of the impurities, even a doping concentration that is only 0.1% higher will cause the coating to undergo irreversible vitrification during high-temperature sintering!"

"At that time, the cathode surface will not only fail to emit any electrons, but will also peel off in large areas like shards of glass."

"Low-dose screening is necessary."

The fellow disciples gave a death order.

"Start with extremely low concentrations and gradually increase the concentration; never be greedy or reckless."

The second connection also ran out and was cut off.

Jiang Ming took a deep breath and gave his last precious opportunity to communicate with the precision instrument pioneer who had proposed the cold trap solution the night before.

"Senior, my pump has reached 10 to the power of negative 5 Pascals, and now we are preparing to sinter and encapsulate the rare earth materials."

"Put away your ridiculous, blind optimism."

The cold voice was like a bucket of cold water poured on it.

"Just because your modified vacuum pump meets the standards doesn't mean that the cavity of your old sintering furnace is absolutely clean."

"Before the cathode material is put into the encapsulation for the first time, an empty furnace evacuation curve test must be performed."

The pioneer warned, word by word.

"First, use your pump to evacuate the furnace once and record the pressure drop rate at different times to find out how much residual moisture is hidden in those old pipes."

"If we don't understand this thoroughly, your rare earth materials will be instantly poisoned and rendered ineffective by moisture as soon as they're put in!"

After all three channeling sessions ended, consciousness returned to reality.

Jiang Ming suddenly opened his eyes, his clothes were soaked with cold sweat.

The Record of Heaven does not directly feed food.

It didn't give him a perfect formula number that he could copy directly, but only three extremely demanding process directions.

He had to calculate the remaining fixed parameters himself.

Jiang Ming grabbed Qian Xuesen's lecture notes from the corner of the table and then opened the Russian internal dictionary that Chen Zhiyuan had given him.

These two books are his best theoretical cover right now.

He extracted the basic emissivity data from the incomplete Soviet records and applied it to the thermodynamic formulas in his lecture notes.

The pen nib rubbed wildly on the scrap paper, leaving streaks of deep blue ink.

Since we must conduct low-dose screening while minimizing material consumption, we must design an unprecedentedly stringent orthogonal experiment.

He cut the fifty grams of cerium oxide into several equal parts on the paper.

Based on the risks of vitrification warned by the pioneers, he significantly reduced the conventional proportions used in later generations, listing three of the most conservative initial verification parameters on paper.

0.5 percent.

One percent.2%.

Two percent.0%.

These three trace doping ratios can ensure that the material will not suffer catastrophic large-scale breakage even if it is affected by impurities.

With the protection of a hydrogen-nitrogen mixed gas and a stepped heating curve, the activity limit of this batch of aged materials can be fully determined.

After writing the last number, Jiang Ming put down his pen and let out a long breath.

He carefully folded the detailed process sheet.

But just as he was about to put it in his pocket, his gaze suddenly fell on the thick, old hardcover notebook on the corner of the table.

The day before yesterday at noon in the workshop, he casually slipped the letter Chen Zhiyuan had sent from the Northwest into this notebook.

Later, Da Liu casually mentioned that Xiao Li stayed in the workshop alone for a long time that noon because of a stomachache.

Liu Shouxin had already exhausted all means, both overt and covert, to drive him out of the electronics factory.

Xiao Li's series of actions that day were definitely not accidental.

This core notebook, which records the vulcanization parameters of fluororubber, interference tolerances, and details of exhaust valve modification, has probably been tampered with.

Jiang Ming's eyes turned completely cold.

He and a group of veteran workers were working themselves to the bone in the workshop, but someone was watching them closely, trying to steal their achievements.

If the parameters in the notes have already been leaked, Liu Shouxin is probably waiting for his final cathode coating formula so he can use this data to claim credit in ministries or set a trap.

Jiang Ming sat up straight again and pulled a brand new blank sheet of paper from the drawer.

He picked up a pen and wrote down a set of dead-end parameters that completely contradicted the pioneers' warnings.

"Cerium oxide doping ratio: 3.8 percent".

"Sintering process: rapid heating to 1200 degrees Celsius, with no gradient heat preservation."

This fake process of rapidly heating high concentrations, without knowing the impurities, will absolutely cause catastrophic glass transition cracking and shattering of the coating.

Jiang Ming folded the fake process sheet in half, deliberately revealing a corner of the paper with eye-catching data.

Then, he opened the old hardcover notebook and blatantly placed the fake note in the most conspicuous position on the first page.

I'll bring this notebook to the workshop tomorrow.

If anyone dares to steal these parameters and try to replicate them, whoever steals them will be held responsible for the oven's failure.
