Chapter 509: First update due to temperature difference
It snowed heavily in the middle of the night. The next morning, Zhu Wentian came out and squeezed a handful of snow, rubbed it, and shook his head.
"What's up, Hanhan?" Seeing that there was no one around, the leader asked in a low voice.
"It still needs to cool down. The sudden cold air directly pushes away the transitional warm air. If it snows, we can't have a snowball fight or form a group."
Zhu Wentian again Grab a handful of snow and squeeze it. It feels bad and hard, similar to marshmallow or granulated sugar. Now it is just granulated sugar and cannot be pinched together.
If the weather is warm and the warm and humid air rushes over, the snow will form into a ball, like marshmallows.
If the snow is thicker, people will fall if they pounce in it.
The current one is a little thicker, so when someone pounces on it, it will be slapped on it, which is very uncomfortable.
Feel the temperature again, the wind is blowing, northwest wind.
Looking at it this way, it will be colder tomorrow, and it will be dry and cold.
The manager took out both the mercury thermometer and the alcohol thermometer and compared them, "There is still a slight difference, the difference is 0.5 degrees."
"Because our technology is not good enough. , the alcohol is relatively accurate. The village laboratory spent a lot of effort to get the magnesium to purify the alcohol, and the ferrosilicon was burned out like porcelain."
Zhu Wentian looked at it. I looked at the two thermometers and saw that there was a deviation, so there was nothing I could do about it.
He has worked hard to purify the alcohol, including quicklime and magnesium.
Then use the pressure gauge extracted from the depth of the water again and again to calculate the atmospheric pressure. Under similar circumstances, compare the boiling of water with the mixture of ice and water, and give a numerical scale of zero degrees and one hundred degrees. .
Now we actually need an extremely cold temperature, which is a temperature reaching minus 40 degrees.
Because the alcohol thermometer can contain this temperature, but mercury cannot.
Then when the mercury thermometer reaches the limit, you can know the error by comparing it with the alcohol thermometer.
This is in degrees Celsius. It is particularly easy to infer it after knowing some data.
Of course, he can also come up with a temperature unit and rules himself and let others listen to him.
But no, it will disrupt his knowledge structure. This is the system he learned. After changing it, he has to change it again according to the change. Why?
"Hanhan , in fact, it is most effective for hatching eggs of chickens, ducks and geese, and it also depends on whether the person has a fever.
When we return to the north, it is best to be cold below 40 degrees in winter, so that the mercury thermometer will not work. Let’s continue to measure it.
In this way, we can produce a lot of thermometers and use them in key places in Ming Dynasty.”
The director took out several more thermometers and compared them with each other. Wandering between 0.5 degrees error.
"Find a way to purify the kerosene on the way, and then get a kerosene thermometer, it can reach minus 30 degrees."
Zhu Wentian wantsMake some kerosene thermometers and use them as comparisons. Kerosene is actually not accurate either.
"We can't let the prince and King Qin get sick from the cold. We came here to test some things, especially to ensure their safety.
Anyway, I am not used to it now. I didn't have it when I was in Nanjing. It’s been so cold, no wonder they all said that northerners don’t want to take a bath. Why take a bath?”
The village leader said and sent the thermometer back. He hadn’t taken a bath for several days. He used to live in Xiaqiu Village and was poor. It has nothing to do with bathing.
There is a river next to it. Everyone can swim. Go for a swim and treat it like a bath.
There is also a river next to it. If you jump in, you will probably be frozen and unable to get back out.
"After entering the desert, there is no shelter around, and the cold wind blows, and you can truly feel the bone-chilling cold."
Zhu Wentian rubbed his hands on his body, and then took off his military coat. The two sleeves are closed and the forearms are inserted together.
"How can you get the fragrance of plum blossoms without experiencing a bone-chilling cold?"
“There are no plum blossoms in the desert. You will know as soon as you step in. The sand will take away a lot of your strength when taking a step, which is different from walking on a hard road on flat ground.
Logistics requirements Follow up, Zhu Biao and Zhu Feng have to come down and walk. If you can't take the car, you can store the car before entering the desert.
Our village wants to buy camels, buy them separately, and use them for our village's car and the prince's car. It’s okay, but our village can’t live without it.
As long as we pay more, some people will be willing to sell camels. We can put skateboards under the cars so that the wheels can be dragged around. ”
If Zhu Wentian gets serious, Zhu Biao and Zhu Xi's cars and chariots will be abandoned, and the same will be true for the others. They can only rely on horses and people's backs.
If there are no cars in the desert, there should be no cars.
Xiaqiu Village had to buy more livestock, especially camels, and then add skateboards under the wheels to drag them along.
You cannot throw away your car. Having a car from Xiaqiu Village ensures your chances of survival in extreme conditions.
There is a set of laboratory equipment and many state-of-the-art technical equipment inside, which must not be thrown away.
"The people around the desert will have less livestock to use, especially camels." The chief considered the people's problems.
"What are you going to do with it in winter? Sell it to us first. Oops, we're about to meet the team coming over there. Just in time, let's trade with them."
As Zhu Wentian said this, he thought of the ten people coming back. Ten thousand troops, escorting the prisoners, have almost arrived.
It was agreed that on this route, the returning team must have a large number of camels, so the cows were given to the other party in exchange for their camels.
Two days later, the team waiting here finally saw the people coming from the other side.
As soon as everyone arrives here, regardless of whether it is cold or not, drink water first, including the prisoners.
"Your Highness the Prince, Your Highness the King of Qin, why not take a detour?" Liu Chong was afraid.
Seeing the appearance of 100,000 soldiers and a large group of prisoners, I felt that this road was filled with life and death.
Because people died, more than a hundred soldiers of the Ming Dynasty died on the way back.More than 400 prisoners died.
Now everyone knows about coal mines, and people from even the farthest places come to dig coal and bring it back.
After receiving the news, people from surrounding prefectures and counties came over one after another. You don’t have to pay a penny for the coal here. You can take the selected coal away and pack it as you like. You can pack it whenever you want.
"The cattle and some horses that cannot enter the desert have been raised well. Give it to them, and we will take over their camels and stay for another three days."
Zhu Biao disagreed, and Xu How did General Da charge?
You can still adjust yourself. At that time, the Chinese army did not have time to adjust. They just fought all the way forward, fought hard through the desert, and engaged the enemy as soon as they passed.
Three days is the time for camels to recover after continuously crossing the desert. Every camel has lost weight, but it doesn’t matter. As long as they are given enough fodder, water, and salt, they will gain weight quickly.
Now I have bought a lot of camels, and they are fed as well as the camels that came back from distant places.
Bean cake, bran, highland barley and barley puffed into granules.
The camels are happy, what about camel thorns and salix, stand aside, we will eat them today.
Yes, camels can actually eat camel quills and other foods that normal people find difficult to swallow.
But it does not mean that camels can only eat these. Give them better feed, they will not eat camel thorns
Feed camels cactus and candied haws, as long as the camel tastes Once you have experienced the taste of candied haws, you will never touch a cactus.
To save time now, give the camels good food and puffed food.
There was wheat bran in the water, and there was a separate trough of salt next to it.
The camels that came over ate like crazy. Let’s just say they had never had such a good meal in their lives. Please remember to collect it, the latest and fastest website without anti-theft, free to find books and add books, you can join the qq group 952868558
