Zhao Min let the fitter in the workshop make twice the parts, so that the parts can be replaced if they are damaged. This careful, let Chen Mo a little happy, at least a set of spare parts for selection.

All the parts were transported to Chen Mo's laboratory. After the staff left, Chen Mo asked ten robots to start carrying the parts and formally assembling them.

”Mo nu.”

”Brother Mo, Mo Nu is here. What can I do for you?” The childish voice of Mo Nu rang out.

Now the dialogue between Mo Nu and him is more and more diversified, learning all the time, and intelligence is becoming more and more complex, which is expected by Chen mo.

”Write a paper on earthquake early warning. The name of the paper is ”Research on earthquake early warning”. Write down the principle of making some seismographs, the core principle and the seismograph manufacturing technology, but do not write it up. ” Chen Mo said.

Before the third army moved, the grain and grass first published the paper, and then formally manufactured the equipment. Any equipment needs a theory to support.

The earthquake is caused by the fracture and dislocation of the underground rock strata. The earthquake always exists on the earth. Usually, the vibration level is too low to be detected. There are nearly 8000 earthquakes below magnitude 2 every day. These earthquakes are too low to have any impact at all.

Before the earthquake, there will be ”piezomagnetic effect” in the underground rock under the action of geostress, which will cause the local change of geomagnetic field. When the underground rock is faulted and staggered, the earth stress makes the rock compressed or stretched, which causes the change of earth resistance and local change of earth electromagnetic field.

And before the earthquake, because of the accumulation of geothermal energy, or because of the strong gravitational action of underground rock, a lot of heat is generated due to the intense friction. These heat overflows from the surface of the earth, resulting in the appearance of geothermal energy.

Some earthquake clouds are generated because of the presence of Geomagnetism and geothermal energy.

The combination of geomagnetic field anomaly, geothermal change and seismic wave change makes it possible for earthquake early warning.

Chen Mo, a seismograph, uses these principles to monitor the activity of the rock layer at the bottom of the earth, calculate the time of rock fracture and dislocation in the fault zone at the bottom of the earth, and achieve the purpose of early warning.

”Brother Mo, the paper has been written. Do you want to publish it now?” Said Mo nu.

”Show me.”

When Chen Mo went to the computer, a paper manuscript appeared on the computer desktop. Read carefully and make sure there is no problem before you open your mouth.

”Send it to nature.” Chen Mo said.

”International or domestic?” Asked Mo nu.

”International, domestic bimonthly, international faster.” Chen Mo said.

”Brother Mo, it has been sent successfully.” Said Mo nu.

Campbell is preparing this week's weekly content, magazine's email, every week, will receive a lot of papers from all over the world.

They are well-known comprehensive science weekly in academic circles. The magazine mainly reports major discoveries and breakthroughs in the scientific world and is very strict in content.

As the editor in chief, it is very important for him to determine the weekly papers.

Before long, an editor came in and hurriedly put a paper on Campbell's desk.

”Editor in chief, this is a paper from China.”

”Chinese?”

Campbell frowned. In his subconscious mind, what good thesis can China have?

”What is it?” Campbell didn't look at it.

”Research on earthquake early warning”
