The big era starts in 1983

Dong Yixiang saw hairtail, and there are hairtails here in Tianshan.

In his opinion, this is really too extravagant in Tianshan.

Ding Er smiled: "What kind of old calendar are you? I'm afraid you don't know the global logistics system of the Ninth Factory. I know one thing. It is definitely not an ordinary transportation. This is really a very high-level thing. The transportation cost , Warehouse configuration, etc., are a set of things that are very particular, so sea fish can also be found in Tianshan, and it must be more expensive than the imperial capital, but the price is limited."

"Really?"

"real."

After Ding Er replied, he continued: "Ten years ago, my baby's mother heard from the neighbors that there might be sea fish in the vegetable market. It was just a few days ago. Then every day before dawn, I went to eliminate it. The place where we live One piece, we talk about sea fish every day, you must know that fish in the river are not often available, let alone sea fish.”

"Yes." Dong Yixiang also stayed in the mainland, and he knew that feeling.

He put a piece of hairtail in the bowl, and the taste on his tongue made Dong Yixiang's eyes light up: "This, does it feel fresh?"

"Fresh transport, this kind is expensive. There is another kind that is frozen into ice cubes, which is cheaper. But the taste is far from this kind."

Dong Yixiang continued to eat: "I never saw the sea when I was a child, and neither did the adults around me. I just thought about what a magical place the sea is."

Ding Er is also recalling: "Ten years ago, my baby followed his mother to buy fish, and even wrote a special diary."

Dong Yixiang said: "It should be frozen in a large piece of ice, and then the fish's head should be cut diagonally with a knife, and the ice can be smashed to get the fish out. Anyway, the ice in your place can't be melted outside in winter."

"Yes, yes, don't smash the ice, bring ice when you buy it back, the ice costs the price of a fish, you have to smash it."

Recalling the past, both of them were smiling.

Dong Yixiang said: "It seems that overnight, many things in our memory no longer exist, and everything we see has changed."

"That's right, it's changed. Before the Chinese New Year, there will be a train of tuna coming over, so they don't have to worry about selling it. Many people here in Tianshan have money in their pockets, and they are willing to try something new during the Chinese New Year. This Fish Nine Factory It’s one thing for a trading company to make money, but wouldn’t it be a good thing for people who haven’t tried it to have a taste.”

"Right."

It's really almost the new year.

This year's New Year's goods will be more abundant than last year, and the gradual improvement of the logistics system will also greatly reduce the cost of transportation.

The same goes for Factory Nine.

Ganfan Renshe is still looking forward to the arrival of fruits from the beautiful southern continent.

However, they never expected it.

The old nest was copied by others.

Mr. Ren personally led the team, went straight to the activity center of the Ganfanren Club, and personally rummaged through the secret warehouse of the Ganfanren Club.

"Found it, this is it."

A lunch box.

A mere lunch box is worth visiting the secret warehouse of Ganfan Renshe by Mr. Ren himself.

After several researchers took the lunch box, they were shocked.

Mr. Ren said: "I heard a rumor before. In order to have hot meals in extremely cold places, these guys researched a kind of insulation layer for lunch boxes, using high-purity silica gel. Combined with the synthesis of oxidized fibers, it is soft and strong, but it is not practical in the end because the cost is too high."

Several researchers looked at the lunch box and wondered if the Ganfan Renshe was crazy. This is no longer a problem of high cost.

"Go and test the data, and then others will double the things here. I guess there are some good things we don't know about."

"Yes."

The secret small warehouse of the Ganfan Renshe was lost just like that.

Soon, a set of data was placed in the conference room of the Space Research Institute.

"It has been tested. After unfolding, this kind of lunch box insulation cover can reach 0.014 square meters per gram, and the weight per cubic meter is only [-] kilograms. The thermal conductivity is [-]w/(m·k), and it has excellent dielectric properties. electrical properties."

"Who researched it, the list?"

After the list is handed over.

"There are four people in total, one is from the Material Research Institute, one is in charge of improving a certain equipment in Binghuo Island, and the last two are from the Sky Research Institute and the other is from us, but when the lunch box was made, our institute This one is the second year of graduate school, led by the one from the School of Materials Science and Technology."

"Well, think of a way to get someone here."

In other words, how could Ganfan Renshe come up with this thing in the first place.

After inquiring, all the people in the meeting laughed.

The idea is very simple.

Their goal is to ensure hot water of 24 degrees in the snowy area, at a low temperature of minus [-] degrees, and after [-] hours, it can still exceed [-] degrees.

It's that simple.

They researched this kind of lunch box set, except for being expensive, it really has no disadvantages.

Later, there were three, four, and five generations of this material, until now it has developed to No.70 formulas, the cost has been greatly reduced, and it has been used in some equipment insulation layers of the Sky Research Institute.

The cost is reduced, and the data is naturally not as good as the original.

At that time, no one thought that it would be used on the moon, and at most only the low temperature environment in the sky in the atmosphere was considered.The result is that the balance between performance and cost is given priority, and the cost is really reduced with repeated improvements and changes, only one-thirtieth of the original.

At this time, what Mr. Ren wants is to use it in an environment of minus 180 degrees, or even minus two Baidu.

Then, this kind of material will continue to study in another direction.

Instead of thinking about reducing costs, think about improving performance.

The one in hand now, according to data calculations, can withstand about minus 130 degrees to minus [-] degrees.Whether it's enough or not, Mr. Ren doesn't know, but he needs better materials, Xia Guo's own cosmic clothing, and the Cosmic Research Institute of the Ninth Factory must be perfect.

Soon, someone came in with a gray bean-like ball.

Then a tile was brought.

"Ganfanrenshe, a kind of burning pellet used to heat food in Xueyu, was abandoned because of its low cost performance. It is stored in a sealed metal cylinder in a small warehouse. I only took one pellet, so you keep looking at it."

After speaking, take a match and light it.

The small particles began to spray and burn from one point, and the force of the spray was particularly strong.

Don't underestimate the small size, it burns for a long time.

The most amazing thing is that after burning, there is almost zero ashes.

"interesting!"

The person who brought this granule said: "The calorific value is too low, and it can't be compared with our professional solid fuel. I show you this, just to say that Ganfan Renshe is really talented. This small granule It was made by a doctoral student in the Institute of Chemistry, and I have arranged for people to prepare the formula, and we are a little interested in the fact that there are almost no residual substances.”

Another person came in: "I got the formula, and I also found out that this small particle has been improved to No. 16 times, and it is used in a certain model of the new Swish 120 as a propellant."
