The people in the workshop almost cried tears of joy and felt that they had succeeded.

But when he saw Lin Yan slowly shaking his head, it was like a basin of cold water pouring down.

Bai Chen sighed in his heart, "You mean it didn't work out?" ”

Lin Yan looked at everyone's nervous appearance and said with a smile: "Don't be nervous, these papers seem to be successful, but they still need to be improved." If you look closely with your mental power, you will see the difference. ”

Bai Chen was busy looking at it when she heard it, and she found the problem a few minutes later.

"The thinner the paper, the more thorough it dries, and the thicker the paper, the only surface is dry, and the moisture inside is not completely evaporated, and there are residues."

"Not bad. We overlooked a problem. ”

Bai Chen nodded, "Different paper drying times should be different, but we forgot to consider this when drying." ”

"That's right. The drying time and temperature have an effect, and we have to do many more tests to determine the drying time and temperature of each paper. ”

This is a huge workload, the relationship between the number of times of papermaking and the temperature time, the support of test data, to find the law, in order to better control the quality of papermaking.

Lin Yan didn't mention these before, because the requirements for paper were not so high, as long as the paper could be used. But when she is personally involved, she will make a mistake, either she will not do it, or she will have to consider it comprehensively, and the variables of various factors must be taken into account.

Bai Chen was inspired, and Lin Yan's words allowed her to find her direction. The whole process seems simple, but in fact, every process must be strictly controlled.

The two studied in the paper workshop for more than a month and found a little pattern.

In fact, the paper made at this time can be used, and the pass rate has reached sixty percent, but they are still not satisfied and want to improve the pass rate.

It has entered the cold season, in addition to studying papermaking, Lin Yan's daily task is to teach Hongling and them.

As the difficulty of the class increased, she carefully observed everyone and found that they were fascinated, completely immersed, and did not look stumped before continuing to speak with confidence.

Different from the basics, the learning is now more esoteric, which involves a lot of abstract thinking, which can only be understood by imagination.

The production of yellow paper has also increased, and everyone has paper. Each person holds a stack of yellow paper and a notebook bound with twine, and writes down the key points with a charcoal pen.

A thin book, 20 centimeters long and 15 centimeters wide, with a total of 25 pages. This is a new product from the paper mill and sells for 1 dime.

There is also a piece of paper sold by the sheet, a sheet taken from the frame of the paper removal mold, 80 cm long and 60 cm wide, and sold for 2 cents.

The production of paper has not expanded, and the quantity is limited to sell so expensive. Now the process is stable, and when the cold season passes, expand the scale, and increase the output, the price of paper will naturally come down.

Many people hesitate for a long time before they buy one, go home and cut it into many small pages, and are reluctant to use it.

The people in the laboratory have their own salaries, and they have Bai Chen's back door, so they are so extravagant, and everyone uses a small book.

Time passed quickly, and when Lin Yan's class was more than halfway through, it was already the end of December, the cold season was about to pass, and the new year was about to begin.

At the end of the year, the arbitral tribunal convened a general meeting, at which 10 delegates from each group were selected in addition to the original public servants. Summarize the major events that happened this year and plan for the coming year.

The people in the laboratory participated, and they asked all kinds of questions, listed their difficulties and problems that needed to be solved.

It was also at this time that the participants realized that everyone in the laboratory thought very differently from them.

For example, they are talking about grinders and grinding discs, frame cars, what these things are, they are all confused.

Although the people in the laboratory were very detailed, they could hardly paint a picture of what they had never seen before. It's just that after knowing the purpose, I feel that it is necessary to arrange it.

Taking into account the views of the public, the arbitral tribunal approved the application for funding for the laboratory and agreed to increase the number of personnel.

It's not okay to disagree, what they put forward is related to all aspects of life.

Everyone has long tacitly agreed that next year's theme is to open up the wasteland and plant wheat, and seeing that January is coming, some people have already packed up their farm tools and are waiting for the weather to warm up.

The first batch of wheat planters has been selected, a total of 30 households, each family can get 10 catties of wheat seeds, and when the wheat is harvested, 10% will be left, and the rest will be handed over.

Since so much wheat is to be planted, there is a great demand for mills, grinding discs and rack cars that Lin Yan said. Like they say, it's much more efficient with the help of a tool and doesn't take longer.

Alan said: "Under the leadership of Lin Yan, the people in the laboratory are all excellent, and they must work hard in the future." The arbitral tribunal has deliberated, and you have made a great contribution this year by giving each of you a bonus of 1 yuan. ”

Lin Yan said happily: "Thank you, Alan, we will definitely do a good job in the future." ”

Who would be unhappy if they had money?

On the first day of January in the fifth year of the solar era, thirty families were selected to come to Lin Yan's house to collect wheat seeds. They were all thrilled to be chosen.

Yesterday, Lin Yan had already called them together and explained the essentials of planting wheat for a day, which sounded very demanding, and they had to go down to the field to take care of them every day, but they were still very happy.

This is an honor, and as the first batch, it has a different meaning.

Just imagine how glorious it would be for every household to grow wheat in the future.

Nowadays, people's lives are getting better, the living standards of each family are gradually expanding, and the comparison between people naturally appears.

Who doesn't want to have a doll like Lin Yan, but unfortunately they can only think about it. There are also the ten people in the laboratory, each of whom is the envy of others.

Every time Lin Yan gives wheat seeds, he must earnestly advise him to farm the land with heart. Wheat is too delicate to be compared to thorn and needs to be carefully cared for before it can be harvested.

The land where each family grows wheat must be reported, and the flowers will lead people to conduct random inspections from time to time, and pay attention to the situation in the field at any time.

Lin Yan also had his own careful thoughts, but he didn't say it. She plans to wait for the wheat seeds to be sprinkled in the ground, and she should go to see them often and keep a record of them to lay the foundation for future planting.

This year, her plan is to be optimistic about the wheat in the field. It's just that she doesn't have to work in the field herself this year.

Hua Hong had experience, but she was afraid that she would not be able to do it alone, so Lin Yan's family only planted three acres of wheat.

At the beginning, most of the land that was circled out was wasteland, and a large area was wasteland.

The bonus plans to open all the fields this year, and then plant all the wheat next year.

After seven or eight days, after the soil thawed in the cold season, Tie Er led the oxen and the iron plough to plow the land for Lin Yan's family, about eight acres of land, and turned it all over in one day.

Hua Hong came back in the evening and said enviously: "The ox and the plow are so easy to use, it would be good if we had a cow at home." ”

"What do you want cows to do with that little bit of land in our family? The cow had to be fed on time and on time every day, and it was very difficult to serve. Auntie, let's pay for Tie Er and them to plow the ground. ”

Lin Yan is not envious, the cow is easy to use, and there is a lot to eat, and there must be someone to serve it every day.

The order is wrong, let's look at it this way first, and let the editor adjust it tomorrow
