I failed a course, and the system became my study supervisor.

Chapter 82 ABS Bridge!
The general framework of the drawing follows the original ideas and methods of the research team.

However, there are more diverse changes in the processing of many codes and algorithms.

Many codes that Xu Ling thought had reached their limits could still be optimized in the system drawings.

Many codes that Xu Ling thought were extremely important were deleted or rewritten by the system.

In the end, the entire code can be said to be very smooth and beautiful.

The next day, when many senior students from the School of Computer Science were still scratching their heads in front of their computers, Xu Ling came to the laboratory with the "localized" ABS bridge.

The so-called localization means scanning it to your own computer.

“I’ve got a solution!”

Clearing his throat, Xu Ling spoke loudly.

"What? It's already been solved!"

The eyes of the brothers were filled with disbelief.

I was at a loss yesterday, but how come it was solved overnight?

But facts speak louder than words, and Xu Ling immediately demonstrated all the algorithms.

"Damn! You can actually write like this here? Why don't I have the guts to do this?"

"Holy crap! Look at this, it can be so simple!"

……

For a while, the monkeys on both sides of the river cried non-stop.

But there is still a question in the minds of the brothers.

That is, although the code looks perfect, does it actually run?
Xu Ling smiled faintly and demonstrated it directly without any nonsense.

Whether it is simple data or complex data, the program can run robustly.

"Hey - you can't deny your age. The future belongs to the young after all."

A senior brother said this in an old-fashioned tone, with a sense of desolation and loneliness.

But no matter what, the bottleneck that has troubled everyone for a long time has finally been broken, and excitement and joy are the main themes.

Xu Ling's excitement has not subsided since he got the drawings.

It will only take a few more days to conduct a comprehensive test and inspection of the current system, and the research team will be able to enter the next stage.

That is the simulation and improvement methods of extreme environments!

And this is also the ultimate goal of the entire research project!
……

As the research team progressed, time passed quietly, and now it is mid-to-late November.

This time point is also somewhat special, as it happens to be the midterm exam of this semester.

However, what is worth writing about is no longer the exam as a student, but Xu Ling's entanglement with the exam as a teaching assistant.

On November 11th, at 18: am, there were only ten minutes left before the mechanics exam officially began.

"Please put all items not related to the exam, including reference books, notes, and electronic devices, in designated areas. The exam is about to begin."

Reciting these words that he had heard countless times, Xu Ling had a strange feeling.

"Teaching assistant, can I use a calculator?"

a student asked.

"can."

Xu Ling nodded.

But in fact, Xu Ling had read the entire paper and found that there was no numerical calculation content at all, only symbols.

Letting them use a calculator is just a psychological comfort.

A few minutes later, there was no vacant seat in the classroom. Zhang Zhongyao, who was standing in the middle of the podium, waved his hand, indicating that the papers were to be distributed.

Xu Ling then distributed the counted test papers to the first row.

Ok……

Should I just stand here? Or should I go down and walk around a few times? As the exam began, Xu Ling pondered idly.

Never mind, let’s go and take a look.

Giving them a little sense of pressure can better stimulate their potential.

While thinking, Xu Ling walked around the classroom.

No? You can't do this?
I specifically talked about this in my Q&A class, okay?

Xu Ling looked at a classmate's test paper and felt very uncomfortable. He couldn't help but let out a slight sigh.

This sigh, coupled with a shake of head filled with disappointment, completely destroyed the already uneasy student's mentality.

But Xu Ling seemed not to notice, and continued to look at the students' test papers. He went back and forth and looked through almost all of them, and from time to time he would inadvertently sigh.

In Xu Ling's opinion, it was a case of being disappointed in one's parents.

But in the students' eyes, it was Garen who used Whisper, which silenced and broke the defense.

……

“Be a little stricter when making changes.”

When grading the papers, Zhang Zhongyao gave special instructions.

"It's already difficult, and if they make it even stricter, I'm afraid the score rate will be very low."

Xu Ling felt guilty and reminded him.

"Haha, that's because you're inexperienced. Midterm exams are meant to be difficult, so students can't get high marks. If they get low marks, they'll naturally be more willing to study hard in the second half of the semester."

Then I won’t have to go to Haidilao for the final exam. Isn’t that better?”

Zhang Zhongyao said with a smile.

Xu Ling was immediately filled with admiration and kept praising him in his heart: He is worthy of being a veteran teacher!
But Xu Ling still felt hesitant to write, as the continuous appearance of zero-point questions was really shocking.

Could you please write a formula? I might give you some points.
After correcting the test paper, Xu Ling said that he had tried his best and it was impossible for me to fill in the blank answer sheet.

Don’t blame your dear teaching assistant for the rest.

Since the beginning of this semester, Xu Ling has been in a state of tension, first with his internship and then with the research team.

But when he thought of the wonderful expressions on those students' faces after they learned of their terrible scores, Xu Ling felt instantly relieved.

There was a time when I had difficulty passing the exams!
If you have been caught in the rain, you will have to tear the umbrellas of your younger classmates into pieces with your own hands.

……

After the little episode, Xu Ling naturally had to return to the main track of his research project.

The testing of the ABS bridge has been completely completed, which means that the ABS simulation simulator - ABSE has been officially built.

The next goal is to explore how to improve the stability of PEMFC under extreme conditions.

Xu Ling naturally took the low temperature as the first treatment.

In order not to increase the overall load of the ABS system, Xu Ling's first attempt was to change the properties of the PEMFC itself to adapt to the low-temperature environment.

This again brings us back to the flow field and material issues of PEMFC.

The flow field in the PEMFC in the first generation of ABS mainly considers the efficiency of water discharge and hydrogen absorption.

Therefore, the lung-shaped flow field adopted previously may not be applicable.

Xu Ling had to consider a question: whether to give up some of the performance of reactant distribution in exchange for the low-temperature stability of the battery.

At the same time, it is also necessary to consider whether to change to a known flow field shape or to redesign a shape.

Zhou Chengkang has different opinions on these issues:
"We shouldn't think too much about this right now. What we should do now is to find the maximum temperature that each part of the current ABS can withstand."

This is indeed the case, Xu Ling immediately understood.

Only by finding the current extreme temperature can we have an expectation in mind and estimate the percentage of target increase.

This work is not difficult. The only thing required is the workload. Xu Ling naturally does not need to participate in the whole process, but he has a lot of free time.
