More than half an hour later, Pang Xuelin stood firmly on the runway of the Sunset Project Launch Center in the Turpan Basin.

The overall riding experience of the waverider aircraft is not bad, except that the push back feeling is a little stronger during the take-off stage, and the noise is a little louder during the flight, which is not much different from that of ordinary civil aviation aircraft.

"Dr. Pang, academician Shen Yuan is waiting for you at the command and control center!"

An officer in the uniform of a major stepped forward.

Pang Xuelin nodded to him, and boarded the jeep that came specially to pick him up.

More than ten minutes later, Pang Xuelin's figure appeared in the hall of the "Sunset Project" command and control center.

The atmosphere in the hall was somewhat dignified. On the holographic screen, hot liquid iron-nickel shone dazzlingly, tumbling, and as the spaceship dived, it quickly closed at the stern, instantly filling the space the spaceship passed through.

The Sunset Six is ​​still sinking!

The expressions on the faces of most of the staff were serious, and there were whispers from time to time.

Shen Yuan stood on the edge of the command and control center hall, where there was a huge floor-to-ceiling window, facing the direction of the magma lake where Sunset 6 set sail.

"teacher!"

Pang Xuelin walked behind Shen Yuan and let out a soft breath.

Shen Yuan turned around, and a sharp gaze instantly covered Pang Xuelin's whole body, as if he wanted to see through him.

Pang Xuelin was slightly absent-minded.

Because at that moment, he saw the shadow of an acquaintance from Shen Yuan.

Thomas Vader!

In fact, there is a big difference between the two in terms of appearance and temperament.

Thomas Wade was born in the KGB. His appearance is more classical and tough, and his eyes are slightly cloudy.

Shen Yuan, on the other hand, was an elegant scholar with gold-rimmed glasses and gray hair, which made people fall in love with him at first sight.

The only thing the two have in common is,

It is a flame that will never be extinguished forever dancing in the eyes.

"They're the same kind of people!"

Pang Xuelin thought to himself.

"Xuelin, you're here, tell me, how did you discover the crack in the mantle on the route of the Sunset 6 spacecraft?"

Shen Yuan's voice sounded a little tired, but he didn't show any sadness, as if the little girl in Sunset Six was not his daughter.

Pang Xuelin took a deep breath, and said what he had prepared a long time ago: "Teacher, I found the problem from the ground current data detected earlier..."

"Earth current?"

Shen Yuan frowned, and looked at Pang Xuelin with sharp eyes without blinking.

Pang Xuelin did not change his face, nodded and said: "There is a big difference in the conductivity of the mantle and the core. When we did the route survey before, we did not conduct a quantitative analysis of the data of the geocurrent. When I go back to write a thesis this time, I just want to Using the data in this area, after analyzing the results, it was found that the strength of the ground current was very different at two measuring points at a distance of more than ten kilometers at a place 2,500 kilometers underground. Then I made further calculations and analysis , the results show that between these two points, there should be a medium with a conductivity much higher than that of the mantle material. I can’t think of anything else except the iron-nickel core of the earth’s core.”

Shen Yuan fell silent and did not speak again.

Pang Xuelin was not worried about his lies being exposed.

There is a very close relationship between the earth current and the earth's magnetic field.

The earth current is the main cause of the earth's magnetic field.

There is an iron-nickel core in the core of the earth. This layer of liquid material can flow and conduct electricity, which is called conductive fluid.

Due to the rotation of the earth, the conductive fluid moves.

If there is a very weak magnetic field in the core at the beginning, it will excite current in the conductive fluid. After a very complicated mechanism similar to a self-excited motor, the interaction between the magnetic field and the current reaches a certain stability, forming a geocurrent and a stable Earth's magnetic field.

Earth current is like the blood of the earth, its existence and movement have been discovered by people very early.

Many scientists have even realized that there is no small relationship between geocurrents and earthquakes.

For example, an earthquake is the movement of the earth's crust, and the movement of the earth's crust is exactly equivalent to the movement of the conductor (earth) in the magnetic field (geomagnetism).

This is similar to the principle that a generator has electricity.

The discovery that earthquakes also produce anomalous geocurrents is due to Varley, whose observations of the Canadian earthquake of March 17, 1871, confirmed this phenomenon.

Later, in Japan, both the Kanto Earthquake in 1923 and the Tottori Earthquake in 1949 obtained examples of geocurrent anomalies.

Our country started after the Xingtai earthquake in 1966.

The observation of the geoelectric field is simple and easy, and the cost is low.

Bury two lead plates at a distance of tens to hundreds of meters underground, and connect them to the two ends of the ammeter (milliampere) or voltmeter (millivoltmeter) with wires, and the Observing the daily and annual changes of the pointer, this method does not require any artificial power supply.

In the 1960s and 1970s, many factories, mines, schools and rural areas in my country carried out geoelectric observation, which was one of the important means of mass monitoring and group defense. The common people gave it the reputation of "land electricity".

However, there is a problem that it is difficult to distinguish between true and false land electricity anomalies.

The most important factor causing these anomalies is that the chemical potential of the metal electrodes is extremely unstable, coupled with the complex changes of the natural electric field, the tiny seismic information is lost in it.

Under the objective conditions of limited technical level, China decided to temporarily eliminate the geoelectric method in the early 1980s and focus on the observation of resistivity. This is a geoelectric method with an external artificial power supply: first use The artificial power supply offsets the variable natural geoelectric field to zero, so that the measurement data can be stabilized, and then the electrical parameter of the underground medium-resistivity is measured. This technology is quite successful in the application of engineering exploration.

However, in terms of earthquake prediction, it still has not played much role.

Until this era, human beings' understanding of earth currents is still very shallow.

For example, in the Sunset Project, although the relevant parameters of the ground current were measured, when the analysis was done, they never thought about the impact of the ground current.

"Good job, you go down first."

After a long silence, Shen Yuan spoke again.

Pang Xuelin nodded and asked, "By the way, teacher, Sunset Six...how is it now?"

"The joint between the melting engine and the main cabin broke, and the melting engine of the formation spacecraft used ultra-high-temperature jets to cut through the material in the direction of the spacecraft. Without it, Sunset 6, which only had one propulsion engine left, would be unable to move an inch in the formation. Moreover, the density of the neutron material that makes up the spaceship is greater than that of the earth's core, and the buoyancy produced by liquid iron and nickel on the spaceship is less than its own weight, and now Sunset 6 is sinking toward the center of the earth. It is expected to enter the center of the earth within the next few days!"

Pang Xuelin opened his mouth, wanting to say something, but in the end he turned and left the command and control center without saying anything.

Shen Yuan looked at the back of his disciple and frowned slightly.

For some reason, he always felt that his disciple was different from before.
