Chapter 714: You're doing just fine, why provoke him?

Sure enough, on the stage, Li Yi only pondered for a moment before speaking: "In strong turbulence, there exists an inertial range; the energy transfer of vortex structures has isotropic universality. This is Kolmogorov's foundational theory from 1941."

"The isotropy assumption in our model is only aimed at the inertial range, which conforms to the physical nature of the turbulent energy cascade."

"Additionally, if you read your paper carefully again, you might find that you also specifically noted that the asymmetric data of HL-2M originated from boundary layer measurements, while our simulation focuses on the plasma core confinement region."

Li Yi's meaning was very clear: your own paper's data comes from boundary layer measurements, which is completely different from the focus of our simulation data. The 7% asymmetry you mentioned just now has nothing to do with us; don't come here trying to pick a fight.

Zhang Zhizhong remained expressionless, thinking to himself that this kid was indeed brought up by that guy Xu Qingzhou, just as arrogant. "What do you mean by 'read my own paper carefully'? Are you mocking me? Do I not know what I wrote?"

But he couldn't very well say that he knew and was just deliberately making things difficult.

Although he was cursing inwardly, Zhang Zhizhong didn't show it on his face and said: "Conference presentations can increase the probability of results being cited by 52%, but the premise is that they can withstand on-site questioning. Thank you for your answer."

Subtext: It's not that I want to ask too many questions; it's for your own good.

Li Yi also secretly let out a long breath.

Regarding Zhang Zhi Gao's question, he could only answer it himself.

This was like a sect master or elder taking disciples to visit other sects in a xianxia novel.

If even this small problem required Xu Qingzhou and the others to step in, it would inevitably make people feel that the Materials Research Institute was just a hollow shell and that these disciples were all useless.

Opposite him, seeing Li Yi look at him, Xu Qingzhou also smiled and nodded slightly. Overall, Li Yi's answer was perfect.

"However... actually, regarding another detail in the report, I still have a question. This part of the content seems to have been done by Professor Xu."

Zhang Zhi Gao changed the subject and looked at Xu Qingzhou.

To Xu Qingzhou's left, Li Gang felt a bit helpless and was already cursing in his heart. Is this old guy Zhang Zhi Gao ever going to stop? Does he really not care about the face of an old senior at all?

"Please speak."

Xu Qingzhou's expression was calm. This old guy, he hadn't gone looking for trouble with him, yet he was the one who came looking for trouble first.

Zhang Zhi Gao said: "The report mentions 'neutral beam injection angle error ≤ 0.1°', which is on page 7 of the PPT, but a paper published by KIT (Karlsruhe Institute of Technology) in *Nuclear Fusion* a week ago proved that an error exceeding 0.15° will trigger tearing modes. I just did a simple calculation; if corrected, the prediction accuracy of your model would plummet from 98% to 70%."

This was questioning the credibility and academic integrity of Xu Qingzhou's model.

Zhang Zhi Gao's gaze turned toward the old man to one side.

This person was named Whedon Lehman, from the Joint European Torus (JET) device, and he himself was from the Karlsruhe Institute of Technology.

Whedon Lehman stared at the PPT on the stage, nodded slightly, and also discovered the problem Zhang Zhi Gao raised.

Li Gang didn't speak; they had indeed overlooked this thing just now.

That paper in *Nuclear Fusion* had only been published a week ago; before that, who knew that an error exceeding 0.15° would trigger tearing modes?

But... science values facts. Although Xu Qingzhou felt wronged, a mistake was a mistake.

Li Gang sighed inwardly: "Actually, mathematical calculation errors are indeed an extremely common phenomenon in experiments, especially in scenarios that are multi-step, highly complex, or require rapid response. At most, it just lets this guy Zhang Zhi Gao gloat a bit; it's nothing."

To one side, Ren Nan and the others didn't have much of a reaction.

Zhang Zhi Gao was already laughing in his heart. Of course, he wasn't just biting randomly; the paper published by KIT in *Nuclear Fusion* in 2019 had caused quite a sensation in the fusion field.

"I am very happy to explain it to everyone."

Xu Qingzhou stood up, walked to the whiteboard, and while writing, said: "Displaying the assumption of the KIT paper: Tearing mode growth rate formula: \gamma=\frac{\beta_heta}{r}\sqrt{\frac{\mu_0}{\rho}}\cdot\delta"

Zhang Zhi Gao squinted at the whiteboard, sneering inwardly, "I'd like to see what other tricks you can pull."

However...

Looking at Xu Qingzhou's calm demeanor, he suddenly had a bad premonition. ===== CHAPTER 715 =====
