Another world conquest manual

On November 20, 34 years ago, China launched its first scientific expedition to Antarctica.

And what a coincidence.

Today, 34 years later, is November 16th.

The polar scientific research icebreaker "Snow Dragon", which set out 11 days ago, has already met the "Snow Dragon 2", which recently completed its Arctic scientific research mission.

The two ships officially met and reunited at Zhongshan Station in Antarctica.

This is the 38th local Antarctic scientific expedition, which is of great significance.

And it's still a coincidence.

"Snow Dragon" also set out from the port of Modu.

Therefore, through a series of simple formula transformations, one plus one equals two, two plus two equals four, plus the extremely low temperature conditions in the cave.

Finally, it was discovered that a team led by a cold zone scientific expedition expert appeared among Lu Chaoyang and his group. This is also a reasonable thing, is there nothing wrong with it?

After all, the cold-weather clothes are here, so it’s normal for some people to come.

The name of this scientific research expert is Ouyang Dongshan, who is 42 years old this year.

He comes from a supporting unit under the Key Laboratory of Polar Science of the State Oceanic Administration, and once served as a deputy at Zhongshan Station.

However, due to the relatively limited range of majors, there are almost no major achievements.

Therefore, Ouyang Dongshan is currently neither a member of the academic department nor a quasi-academician like Cui Xiaofeng who is only a hair away from the title of academic department.

He is just a researcher who has rarely appeared in the public eye and has remained unknown for twenty years.

However, since he can be sent to the cave site by the command headquarters, there is no need to doubt Ouyang Dongshan's business ability.

When everyone entered the cave wearing heavy cold-resistant clothing, Ouyang Dongshan opened a small slit in his palm.

Then he raised his hand and touched the cold air in the cave with his skin.

Mentioned previously.

The climate inside this cave is extremely low.

Even though Ouyang Dongshan was only seven or eight meters into the cave, the temperature reached minus 20 degrees.

So only ten seconds passed.

Ouyang Dongshan's arms quickly turned pale, and even a few parts tended to turn blue-purple.

However, Ouyang Dongshan didn't take it seriously.

I saw him breathing hard against his skin.

He quickly pulled up the chain as his skin turned red.

Then he turned his head and said solemnly to Lu Chaoyang and others:

"Professor Lu, there is something wrong with the wind in the cave."

Lu Chaoyang, Cui Xiaofeng and others looked at each other and asked:

"Researcher Ouyang, what do you say?"

Ouyang Dongshan thought for a while and made a chopping gesture with the palm of his left hand in the air on the left side.

The right hand repeated this action on the right side.

Then he said:

"Professor Lu, assume that the position on my left hand is the end of the cave, and the position on my right hand is the entrance.

So what should the wind direction be normally? "

be honest.

When Lu Chaoyang heard the word wind, the first thing that came to mind was Yasuo's wind wall.

However, this thought was fleeting, and the 0-21-8 player quickly removed this distracting thought.

I saw him looking at Ouyang Dongshan strangely, and said without knowing why:

"Researcher Ouyang, the end of the cave is sealed and there is only one air inlet.

Therefore, the wind direction must be from outside the cave entrance to the inside of the cave entrance, that is, from the right to the left. "

Ouyang Dongshan put down his hands when he heard this and looked at him deeply:

"But Professor Lu, didn't you notice?

Wind direction in the cave

It blows from left to right. "

Lu Chaoyang was stunned for a moment, then frowned.

In a cave with a sealed interior, the wind blows from the inside out?

How can this be?

But thinking about Ouyang Dongshan, there is no need to tell such lies that can be exposed immediately.

So Lu Chaoyang was silent for a few seconds and took out a piece of paper used to record chores.

The document paper is very thin, and under the influence of wind, it gradually begins to bend in the direction of the wind.

And its curved direction is clearly

The entrance of the cave!

In other words, Ouyang Dongshan's judgment was correct.

There is obviously something wrong with the wind direction in the cave!

At this moment, Cui Xiaofeng on the side suddenly interrupted:

"Researcher Ouyang, let me ask a question. Is it possible that the cold and high pressure inside the cave caused this situation?"

Ouyang Dongshan looked at the wildlife expert in surprise, obviously surprised that he could ask such a question across disciplines.

But he soon shook his head and explained:

“Everyone should know that the pressure difference between the wind and the horizontal direction is formed by the horizontal pressure gradient.

The temperature is about minus 80 or 90 degrees Celsius at the end of this cave. Theoretically, a strong downdraft will definitely form.

After this downdraft sinks to the bottom, it will form what Professor Cui calls a cold high pressure.

And in front of us. Let me think about it

Fifteen meters, maybe. There will be a low-pressure zone similar to the subpolar area at fifteen meters.

But then again.

It is even more difficult for the national football team to win all the remaining top 12 matches and qualify for the four- to five-level wind in a cave of more than 40 meters.

Especially since the entrance of this cave faces south, there is actually a certain amount of wind that is hedging from the outside.

It just doesn’t feel obvious. "

After hearing Ouyang Dongshan's words, the scene fell into silence.

Ouyang Dongshan’s meaning is actually very obvious:

That is, although the temperature at the end caused by the ice coffin is very low, it is definitely not enough to form a gust of this intensity.

In other words.

There might be an opening somewhere at the end of the cave!

Then Lu Chaoyang thought of something:

"Researcher Ouyang, you said there is a mortgage about fifteen meters in front of us?"

Ouyang Dongshan nodded:

“The subpolar low pressure zone is when the subtropical high pressure meets the polar high pressure air, and the warm and light air flow climbs above the cold and heavy air flow, thus forming an updraft.

The higher the altitude, the less air there is and the air pressure naturally decreases, thus forming a low pressure zone.

The length of the cave is more than forty meters, but the temperature ranges from extremely cold to zero degrees at the entrance of the cave.

Therefore, a polar-like sub-low pressure zone will definitely form in the middle area. "

When Lu Chaoyang heard this, he immediately turned his head and looked at Zhu Yuhao.

Zhu Yuhao realized what he meant, nodded and said:

"Yes, Professor Lu, the location of the colorful fruit tree is almost there."

Lu Chaoyang nodded slightly, thoughtfully.

Then more than ten seconds passed.

He waved his hand and said:

"In that case, let's move on and see what's ahead.

Major Su, please arrange for a few people to take samples of the rocks in the cave at intervals of five meters, and then send them back together for analysis. "

"clear!"

As soon as Lu Chaoyang finished speaking. Everyone started to take action.

Da da da--

The BOO scientific expedition ice boots weighing 6.8 kilograms came into contact with scattered stones in the cave, making a detailed and messy sound.

However, apart from the very low temperature, there seemed to be no other dangers inside the cave, which was as quiet as a tomb.

So it didn't take long.

Everyone then arrived at the first and only important place on the way to the end:

The location of colorful fruits.

Note:

Today, I accidentally saw a review of a latest chapter by a book friend from the earliest period (that is, there were only about 20 collections and five or six reading at that time). I felt a lot at once. I didn’t cry, but my eyes were a little sore. .

It turns out that many people are still there.

The greatest sense of accomplishment in writing a book is nothing less than this.

In the previous chapter, a classmate had a question, saying that Pathfinder was not a domestic brand, so why would they ask him to customize scientific research uniforms?

I checked specifically and found that Pathfinder has been a supplier to the scientific expedition team since the 26th Antarctic scientific research. In October last year, Boston launched a co-branded model for the scientific expedition team, but in fact it was a side project of the concept, not it. Clothes provided.

The shopping list of the scientific expedition team is made public every year, and Pathfinder has always been the supplier. It is probably because of its relatively large technical advantages.

As for the worries about leaks, whether there could be any leaks in the clothes, this kind of materials will definitely be strictly inspected before being distributed.
