Reborn in 1977, I will no longer be my brother's blood bag.

Ten records.

Some are written clearly.

The machine is turned on at what time, when the material is changed, and how much it deviates from its intended path are all recorded on it.

Some people find it too troublesome and just write two words on the edge of the paper.

Lin Xiuhe first put the records of the same volume of materials together.

The material passed the test five times in a row, and it was always the first roll of material delivered by Factory A.

Problems started occurring in the last three trips, and the materials had to be changed each time.

The rollers were adjusted after a material change.

The spring was replaced once.

Another time, they didn't touch anything, they just put the new roll on.

The lunch bell rang.

The researchers gradually made their way to the cafeteria.

Zhao Wenbo passed by her desk and saw that she was still flipping through her notebook.

"If it gets any later, even the cabbage stalks will be gone."

Lin Xiuhe closed the notebook.

What time is the test run this afternoon?

Two points.

Which roll of fabric should we use?

"It was delivered by Factory B yesterday."

"Last time, the one who got the most unfair treatment was also Factory B."

Zhao Wenbo stopped.

He took the record and read it again.

"You doubt the information?"

"Let's give it a try."

When the two arrived at the cafeteria, it was already full of people.

Mr. Sun was eating at a table by the window.

His tablemate asked him, "Didn't you go to the cannery today?"

Mr. Sun picked up a piece of cabbage with his chopsticks.

"The project has been cancelled."

"Didn't all the factory's trucks arrive?"

"So what if they came? The new guy said he wouldn't take them, and Engineer Zheng also said he wouldn't take them."

Several people nearby followed his gaze and looked over.

Lin Xiuhe carried the lunchbox inside.

Someone whispered, "Is it her?"

"The one who just reported for duty yesterday."

The experienced chef squeezed through from another table, carrying his lunchbox.

"The decision to withdraw was correct."

He sat down opposite Lin Xiuhe.

"The factory is short three people for the night shift, and they want the machines to cover for them. But if the machines don't work after the modifications, they'll blame the research institute."

Mr. Sun heard it from across two tables.

"Old Xu, stop making sarcastic remarks."

Old Xu shoveled a mouthful of rice into his mouth.

"I'm telling the truth. Your budget of over twenty items even covers which way people walk through the aisles. Write two more pages, and you'll be in charge of deciding whether the cafeteria will serve cabbage or radish today."

Someone in the cafeteria burst out laughing.

Mr. Sun put the lunchbox on the table.

"If you're so capable, make sure your feeding system doesn't malfunction by the end of the month."

Old Xu stopped laughing.

"So I still have to work this afternoon."

He finished the last bite and closed the lunchbox.

"Comrade Lin, the test run is at two o'clock. Could you come and take a look?"

At 2 PM, the testing room was restarted.

Old Xu loaded the new materials delivered by Factory B onto the feeding rack.

The mechanical team first measured the width and thickness.

"All are qualified."

Zhao Wenbo turned on the power.

The steel belt is fed forward section by section.

One hundred times.

Two hundred times.

no problem.

After more than three hundred attempts, the steel belt began to deviate to the left.

Old Xu turned off the machine and checked the feed rack first.

The screws weren't loose.

The rollers didn't move. Zhao Wenbo opened the control box and checked it from beginning to end.

"Signal is normal."

The mechanics team measured it again with calipers.

"The size is normal."

He looked at Lin Xiuhe.

"You said it was material this morning. Now the width and thickness are both fine."

Lin Xiuhe walked to the experimental table.

She did indeed think in the morning that the sizes were different between the two factories.

The measurements taken now are all within the required range.

She picked up the roll of new material and then looked at the remaining old material next to it.

For a moment, I couldn't pinpoint the problem.

Old Xu took both steel strips.

He spends most of his time in the workshop dealing with these things. He held them in his hand, weighed them in his hand, and then pressed them down.

"This roll is hard."

The mechanical team said, "Hardness is not included in this test."

"That would be strange."

Old Xu laid the new material flat on the table.

As soon as I let go, the edge of the steel strip curled up again.

Old materials were stuck to the countertop.

"You see, their temperaments are different."

Lin Xiuhe spread out the forms she had compiled that morning.

"The first five tests were all passed, but they were all using old materials."

Zhao Wenbo immediately reviewed the supply inspection records.

The only data listed is width, thickness, and surface defects.

It has no hardness.

There was no curliness.

The mechanics picked up the two pieces of material and tried it again.

"This roll has a really big rebound."

Old Xu snorted.

"Meeting the size requirements does not mean that the product will be the same after it goes into the machine."

Zhao Wenbo pointed to the form.

"The deviation only started after we changed the material. We had been looking at the control system and the feeding rack."

"The mechanics and controls are probably correct," Lin Xiuhe said, "but the experimental conditions weren't fully specified."

The mechanics team frowned.

"Even if this is found out, what do we do now? The test is due at the end of the month."

"Try a few different materials and run it again."

"Only nine days left."

"Even if it's the heavens, we have to run."

What should I do if I passed the previous five times?

"Keep it." Lin Xiuhe pointed to the record.

"But it cannot be used to prove that all materials can operate stably."

Someone went next door and called Engineer Zheng.

When Engineer Zheng arrived, two rolls of steel strips were already placed on the test bench.

Zhao Wenbo handed him the supply records and the ten test reports together.

"The first five tests were合格 (qualified/passed) using the same roll of material. After switching to material from Factory B, the results started to be off."

Old Xu added a sentence.

"The two deliveries are the same size, but the texture is different."

Engineer Zheng flipped to the end of the record.

"What about the initial draft for review?"

"It was already handed over to the office this morning."

"Take it back."

Zhao Wenbo turned and left.

The mechanics team interrupted.

"Engineer Zheng, are you going to withdraw the conclusion because of this?"

"How was the conclusion written?"

"After 500 consecutive feedings, the operation is stable and meets the design specifications."

Is it still stable after changing the film?

The mechanical team couldn't answer.

Zhao Wenbo quickly returned with the red-covered documents.

The date of submission is written in the upper right corner of the cover.

tomorrow.

Engineer Zheng turned to the conclusion page and handed it to Lin Xiuhe.

"You're saying we can't claim it?"

"cannot."

"Dare to sign?"

Lin Xiuhe took the pen.

"dare."

She wrote her name below the supplementary notes on the experimental situation.

I had just finished writing when the office phone rang.

The secretary rushed in.

"Engineer Zheng, the ministry is urging us to send the materials over tomorrow morning."

Engineer Zheng closed the red material.

"I can't deliver it."

The secretary was taken aback.

"They're asking why."

Engineer Zheng looked at Lin Xiuhe.

"you say."

Lin Xiuhe reinstalled the steel strip from Factory B back onto the feeding rack.

"The original experimental conditions were incomplete, and the conclusions need to be redone."

The secretary said urgently, "The evaluation is due at the end of the month."

Old Xu put away the tools next to the machine.

"Then let's hurry."

Zhao Wenbo picked up the new notebook.

"Shall we run a round tonight?"

The mechanical team also brought over the blueprints.

"List out all the materials first."

Sun Gong was standing at the door of the laboratory at some point.

He was probably there to deliver some farewell materials. After listening for a while, he suddenly spoke up.

"You can't even get this reimbursed?"

Old Xu turned to look at him.

"How are you feeling? Feeling better now?"

Mr. Sun's face stiffened again.

"I was just asking."

Engineer Zheng put the original appraisal materials aside.

"Stop asking. Go to the archives and find the records of the steel strips sent by the other two factories as well."

Engineer Sun pointed to himself.

"I?"

"When you were working on the cannery solution, didn't you say that automation could solve all the problems?"

Engineer Zheng handed him the new form.

"Let's see how many problems automation needs to solve first."

Everyone in the laboratory got busy.

Someone went to collect the materials.

Someone re-listed the number of trials.

Someone disassembled the steel belt that had been delivered crookedly earlier.

Lin Xiuhe stood in front of the feeding rack and wrote the first set of data into her notebook.

The materials that were originally scheduled to be submitted tomorrow have been withdrawn.

There are nine days left until the end of the month for the assessment.

On her first day at the research institute, she didn't get on the bus to the cannery.

However, he personally stopped another conclusion that was already ready to be sent out.

The machine restarted.

The steel belt was pushed forward ten times.

Old Xu measured it with calipers and reported the number.

Zhao Wenbo wrote it down.

Engineer Zheng stood at the door and asked:

"What about the next volume?"

Lin Xiuhe opened the list of materials.

"Volume Two of Factory A"

"Install it."

It was already dark outside the window.

One by one, the lights in the research room came on.
