Chapter 399

"The electric potential energy outside the robbery cloud conforms to the Laplace equation. The electric potential is continuous outside the robbery cloud, and the normal component is also continuous!"

Hearing this remark from the east of Huangpu, Zeng Gucheng and they haven't reacted yet.

Lu Chaoyang, who was more than 1000 kilometers away and followed up the scene in real time, couldn't help it.

Poop.

He sprayed most of the tea he had just drunk into his mouth.

And beside Lu Chaoyang.

The rest of the physics experts didn't react as much as he did, but they weren't as light as he did.

After about ten seconds, several academicians at the scene of the robbery also opened their eyes:

"Sleeping trough?"

Shock!

This word is the consistent inner portrayal of all physics experts at the camp and the robbery scene at this moment!

as everyone knows.

In a conductor, charges gather on the surface in an electric field.

The charge in the medium can not move freely, and polarization will occur under the action of electric field.

In the model, it can be seen that there are polarizer charges inside and polarizer charges on the surface.

Therefore, there are both free charge and polarization charge at the interface between conductor and medium.

If there were no conductor, there would be no free charge at the interface.

Without a medium, there is no polarized charge.

Therefore, at the interface of two media, the normal component of potential shift is continuous.

in other words.

Cloud robbery is a kind of interface between two media.

If this conclusion is found alone, it's no big deal.

But the key is that it has a precondition - the potential is continuous externally and conforms to the Laplace equation.

Laplace equation is a diffusion equation, which is simply used to describe the divergence field.

Its physical meaning is actually very complex, and few students need to understand it.

You just need to know one thing:

What data did they get from Huangpu east φ (R) = a + br.

In the firewood camp.

Looking at Shi Zehong and Lin Li with a half face forced, Lu Chaoyang sighed gently:

"This general solution is the second kind of solution in the coordinate system, that is, the robbery cloud detected by academician Huangpu

It's actually a uniform medium. "

"Media body?"

Hearing this word, Li Yan suddenly thought of something. The numerous second disciple couldn't help saying:

"Professor Lu, do you mean the previous mill series?"

Lu Chaoyang gave her a look of approval, just as the online writer was happy to see the readers who voted for the monthly ticket:

"Yes, academician Guo Zhenyu made a discovery not long ago.

When the robbery clouds gather at the beginning, the number of terms of the mill series sphere scattering field is increasing and has directional radiation!

In order to increase the number of terms of mill series, there must be a uniform dielectric ball.

So academician Zeng put forward a view at that time... "

"At that time, I thought that the medium ball might be Yang Zhengchu himself, or simply his sea of Qi."

At the scene of the robbery, Zeng Gucheng sighed and said to Ma Ning who came back from the negotiation:

"But now I find that I'm very wrong.

Real media ball

In fact, it's the cloud of thunder above our heads! "

Very early to the premise and too.

Modern science does not know much about lightning, but at least one thing is certain:

That is, lightning, or the thunder cloud that forms lightning, can not be a uniform dielectric ball in any case.

So obviously

There must be a problem with the formation of robbery cloud!

And while everyone was talking.

Lin Ziming, who went to collect the remains of the pulse potential detector, just came back.

During the previous launch, a total of three equipment were firm to the end.

The other five detectors were destroyed by lightning before they came into contact with the robbery cloud.

Mentioned earlier.

The original positioning of these probes was to carry out the Mars exploration mission. In addition, after the magic modification of rabbits, the material strength is not low.

Although most of their areas have been completely destroyed by lightning.

But after all, it was only struck by thunder, not completely engulfed and annihilated as the three equipment behind it.

Therefore, some debris of the five detectors fell down.

Lin Ziming's task is to bring the wreckage of these devices back to study according to the observed falling trajectory.

After returning to the scene.

Lin Ziming gives Zeng Gucheng the safe containing the wreckage:

"Academician Zeng, we only found three pieces of detector debris this time.

The largest area is about 0.6 square meters, and the smallest two are only the size of a palm. "

"Thank you, Colonel Lin."

Zeng Gucheng took the safe and handed it to his apprentice Zhuo Yuanxin:

"Small table, you immediately analyze the information of the destroyed surface and sort out a report for me as soon as possible."

Zhuo Yuanxin solemnly raised his chest and replied:

"I see!"

The material of the detector is very strong, so the damage surface is mainly caused by electric energy and thermal energy.

in addition to.

Neither air friction nor impact when falling to the ground will basically leave too obvious traces on the debris.

At most, it is contaminated with some soil or vegetation.

Therefore, the relevant inspection work is not very troublesome and does not take a long time.

In an hour.

A report came out.

"Longitudinal magnetized crack field strength 1.97mj, diffraction effect coefficient 6.922, initiation rate 18%..."

Looking at the reports in front of him, Zeng Gucheng analyzed them one by one:

"There's no problem with the field strength. The field strength of lightning robbery must be much higher than that of local lightning. It's strange if it's low or almost.

The clutter damage is almost zero, that is to say, the thunder robbery does not contain other special rays...... "

But when he saw one of the columns, his eyebrows suddenly twisted:

"Point crossing energy level of 700mev? Eh? Strange..."

Guo Zhenyu looked over his head when he heard the speech, glanced at the report and made a simple mental calculation:

"700mev... Academician Zeng, isn't this value quite normal?

Assuming that the electron atom actually constitutes an electric dipole, the phase difference between the orthogonal polarization is almost this number.

Even if there are errors, the last few digits are at most different, which can not affect the overall magnitude. "

"Academician Guo, it's not what you said."

Zeng Gucheng lowered his head and stared at the number, raised his left hand to the eyebrow, then shook it with his fist and gently tapped it on the side of his temple:

"I always think it's strange that I've seen similar values somewhere..."

Then Zeng Gucheng didn't feel dirty and sat down on the spot - although it didn't make much difference to sit and stand in terms of his height:

"We arrived in Da Mo in July last year and came into contact with things related to electronic energy. Let me think

How much is a light door

And the supercomputing in the dawn plan

The transmission array of Ziqiong city is also a

Oh, yes.

And Xiao Wang said that Wu fan was like an electric eel discharging when singing

But these have nothing to do with electron volts. What's the problem?

Ev... Ev... "

As he spoke, Zeng Gucheng suddenly saw:

"I remember what it is!"
