Chapter 114 Explanation

After Shen Sangyu mentioned the two words "deep sea", Qin Duanshan realized something was wrong.

Deep sea and ocean exploration are different. Currently, the global exploration of the ocean is less than 5%, and the exploration of the deep sea is even less.

According to the international exploration level, there is no real deep sea exploration equipment in the world.

Qin Duanshan was a little interested in the deep sea that Shen Sangyu mentioned.

He took a look at the machine floating in the water. It looked like it weighed about a few dozen kilograms. The engine inside was estimated to be very expensive. No wonder Shen Sangyu wanted so much money.

"What can your machine mainly do?" Qin Duanshan asked curiously.

Shen Sangyu said: "It can be used to survey polymetallic nodule resources and place equipment points underwater. In the future, it can also be used in submarine cables and various industries."

Shen Sangyu paused and said: "However, the funds are limited. My machine certainly cannot meet the requirements in the deep sea, but there is basically no problem in ordinary waters."

That is to say, it is not allowed in this era. If possible, underwater salvage can still be carried out.

However, the technology was basically mature at that time. The network and the submarine can be operated together to develop the role of the submarine to the extreme.

But China is not connected to the Internet now.

She did not mention many of the performance of the submarine. The deep-sea power submarine here has been put into the artificial lake by He Huai for salvage.

During this time, Shen Sangyu said: "But this equipment has another most remarkable feature." As

soon as Shen Sangyu finished speaking, all the students standing in a row at the artificial lake held their breath.

Shen Sangyu said lightly: "This equipment model can dive to more than 3,700 meters deep in the sea."

Shen Sangyu certainly couldn't run to the edge of the sea to experiment, but it was a theory obtained through precise calculations.

Shen Sangyu didn't know how deep the current submarines could dive, but forty years later, China's submarines reached 6,671 meters for the first time in Qingdao, and the deepest reached 7,035 meters. The experiment at that time had completely exceeded the experimental goal and achieved a successful conclusion, which also allowed China to enter the top three countries in submarines.

Now this number is not satisfactory to Shen Sangyu.

Although she had money in her hand, she had to pay for the experiment herself. It was okay once, but if she did it twice or three times, she would eventually spend all her money.

When she did the experiment, China was already rich and strong. Although its economy was not the strongest, it at least had a place in the international arena.

She could get whatever she wanted.

At that time, she didn't care about tens of millions or hundreds of millions, but now she thinks twenty yuan is a gift.

Shen Sangyu sighed deeply when she thought of this, not realizing how many people were shocked by her words: "In fact, if all the materials were complete, we should be able to dive deeper, but the funds are limited, haha..."

Qin Duanshan glanced at Shen Sangyu and was silent for a long time: "Come to my office after class."

Shen Sangyu narrowed her eyes, knowing that her subsidy should be back soon, and happily agreed.

Shen Sangyu's experiment was longer than that of other groups. In advance, Shen Sangyu placed several metal objects in various places in the artificial lake for the submersible to collect. About fifteen minutes later, the submersible floated up, and the surface was shining red.

Qin Duanshan was more excited than Shen Sangyu, and saw the submersible float up and ran over quickly.

After seeing the metal materials salvaged from the submarine, his face flushed with excitement: "They salvaged all of them without missing a single one!"

After saying that, Qin Duanshan stood up excitedly: "Did you two do this together?"

He was talking about Shen Sangyu and He Huai.

Shen Sangyu nodded: "He Huai's main research this time is the mechanical manufacturing of the submarine, and he gave a lot of ideas during the experiment."

She is not bragging, it's mainly because the teacher's brain is too good.

Qin Duanshan: "..."

Qin Duanshan didn't pay much attention to He Huai before. He knew that He Huai was the class monitor and his grades in the college entrance examination were also among the best in the class, but He Huai was really a very lively student.

Among the students who basically only knew how to do research, He Huai was a unique one.

All day long, I am either thinking about where to go for fun or where to eat.

Study?

It is good enough to be able to attend classes.
