Near noon, Li Mengxi, Liu Bei and Guan Yu, the three top rebels, finally set out to patrol the camp outside the city.

During the food shortage period, you could not wander around in the camp because you had to be careful to protect yourself and avoid being stopped and questioned by civilians. But after the food was released, this worry disappeared.

It had been four days since food had been cut off, and the camp outside the city had been set up for four days. This was the first time Li Mengxi had come to the camp in four days.

After entering the camp and walking towards the center, Li Mengxi paid enough attention to everything around him.

He would pay attention to how wide the roads left in the camp were, he would look at the layout of the tents, he would lift his feet and kick them to see how thick the snow was on the ground, and from time to time he would randomly choose a tent and walk in to check it out.

Fan.

Often, when Li Mengxi got into the tent, Liu Bei and Guan Yu would stop and wait for him.

Looking along the way, Li Mengxi saw that each tent was covered with manuscript mats, and the tents that could accommodate ten people were filled with a dozen or even twenty beds.

The manuscript mats that were laid on the spot were not unfolded, only two-thirds of them were spread, and the rest were rolled up and rolled to one side. This resulted in that each bed was very short, and people could not stretch their legs when sleeping on it.

I can only sleep with my legs curled up in a ball.

This is good, as it can allow more people to rest as much as possible.

Li Mengxi also discovered that rolling up the manuscript into a section had unexpected other uses. The end of the manuscript mat was rolled up into a tube, just enough for the head to rest on it, and there was a pillow.

Furthermore, because the manuscript mat is laid directly on the ground, the ground is wet and cold, so sleeping on the ground will be very cold. If you sleep on the ground with a pillow, it will be warmer if you sleep higher.

When Li Mengxi saw that most of the sleeping people in the tent were curled up and tightly huddled in quilts, Li Mengxi saw that everyone was sleeping on their sides, whether to the left or the right.

, all sleep on their sides.

Li Mengxi and his brother both liked to sleep lying down, so he felt a little confused that so many people slept on their sides.

After thinking about it for a moment, Li Mengxi suddenly figured out why.

The root cause is still on the ground. The ground is too cold and the bed is also cold. Therefore, if you lie on the bed, the entire back of your spine has to be in contact with the cold manuscript mat.

When lying on the side, the contact area between the body and the manuscript seat is the smallest, several times smaller. Therefore, in terms of thermal insulation efficiency, lying on the side will be warmer.

After Li Mengxi understood this truth, he thought about it a lot. He concluded that people who freeze to death usually die lying on their sides.

Because no matter where he froze to death, whether he was lying on wheat straw, lying on grass, lying on the ground, or even lying on ice and snow, no matter what the environment was, the ground was cold.

At this time, whether consciously or unconsciously, people will choose to lie on their side to keep warm.

So, regarding this sleeping position issue, what is the difference between sleeping on your back and sleeping on your side?

Li Mengxi thought about how to make camp beds more scientifically. He thought that cold was the enemy of marching camps, but heat was not. Heat was not a problem, but cold was terrible.

Since, when it is cold, soldiers will lie down and sleep to keep warm, then the camp beds issued by the army do not need to be too wide. They can be made much narrower, narrow enough to barely allow them to lie down and sleep, and narrow enough to move a little.

Just like falling to the ground.

The purpose of this is, first, to reduce the width of the bed as much as possible and reduce the weight of the soldiers as much as possible.

Secondly, while the width of the manuscript seat is reduced, the saved weight can be added to the thickness.

What does a thicker manuscript sheet mean?

This means that when sleeping in a humid place, the bed will not get wet easily. It means that when sleeping on cold snow, the mat will be thicker and not so cold.

Therefore, there are two types of beds, one with a normal width but thinner, and one with a very narrow but very thick weight. Therefore, the two beds have the same weight, and the level of drag on logistics is also the same. However,

, on wet ground, cold ground, and uneven ground, the moisture-proof and moisture-proof ability of narrow and thick beds, the cold insulation ability, and the buffering ability are much stronger than ordinary tents.

According to Li Mengxi's speculation, the thickness of the tent has a great influence on the effect of keeping out the cold. In extreme weather, if the surface temperature of the manuscript mat is half a degree higher or lower than half a degree, it is the difference between someone who freezes to death and someone who does not.

In addition to the narrower tents, Li Mengxi also saw that common people used mat tubes as pillows.

There is no doubt that this small detail of resting your head on the mat tube can also improve the thermal insulation effect, because the head is no longer in contact with the cold mat surface below, but is pillowed high, eliminating the head as a dissipation point.

With the contact, the thermal insulation effect is improved a bit.

From this, Li Mengxi felt that he could specifically strengthen the raised structure of the manuscript sheet.

That’s right, I deliberately made the beginning and end of the manuscript sheet a little stiffer. Why should it be stiff?

Li Mengxi is no stranger to manuscript mats. When he was a child, he lived in his hometown and slept on the manuscript mat for many years. When the manuscript mat was rolled up, if the knitting was rough, it would become a very big bobbin and the roll would not be tight.

If braided well, the wheat straw is soft and can be rolled into a round shape.

The reason is here, the rough manuscript will be very high when swept up, and it will be stuck.

Under cold natural conditions, for the purpose of keeping out the cold, it is better to have the mats rolled up higher.

If the height of the mat tube is three centimeters, the cold air erosion on the head will be reduced by one percent.

Yes, the marching straw mat can be specially made stiff at both ends, the head can be raised very high, and the quilt shed can be raised higher, so the thermal insulation effect is stronger.

In addition to armament-related matters, Li Mengxi also thought that since it has been determined that people will lie on their sides when it is cold to keep out the cold, and since it has been determined that in most cases people who freeze to death lie on their sides, then conversely, assuming that a person freezes to death

If he was lying upright or on his back, it was very likely that his body had been tampered with.

This seems to be applicable to criminal diagnosis.

This chapter is not over yet, please click on the next page to continue reading! Li Mengxi came out of the tent.

After he came out, he took out the white silk from his arms and took out the writing brush from a small bamboo tube tied around his waist.

It was so cold that the ink on the brush was frozen.

Li Mengxi put the brush into his mouth and held it for a while. The ink tasted disgusting, and Li Mengxi spit out it several times in disgust.

Liu Bei and Guan Yu laughed when they saw it.

When Li Mengxi took a small wooden board, covered it with white silk, and started writing something, Liu Bei and Guan Yu saw that Li Mengxi actually wrote something again. Liu Bei and Guan Yu were particularly curious.

Out of curiosity, the two people came over and asked, "Xi'er, what did you write?"

Li Mengxi kept writing. He raised his head, looked at Guan and Zhang, and said, "I just entered the tent and saw many civilians lying on their sides on the bed."

Liu Bei and Guan Yu looked at each other, confused. "What's wrong with sleeping on your side?" Liu Bei was confused.

Guan Yu also said, "The ground is cold. Wouldn't it be warmer to sleep on your side?"

Li Mengxi nodded, "Yes! It's just that the ground is cold, and I'm sleeping on my side, right here."

After that, Li Mengxi talked a lot and Liu Bei and Guan Yu were surprised.

Liu Bei and Liu Bei were surprised that Li Mengxi had only been patrolling the camp for a short time, and they saw the civilians sleeping on their sides. Just from this, they could make important discoveries.

Li Mengxi said that the marching mat could be deliberately made narrow and thick, which could not only reduce the load but also improve the ability to insulate against moisture and cold, giving the best of both worlds.

Liu Bei and Guan Yu thought so.

Li Mengxi suddenly asked again. He looked at Liu Bei, then at Guan Yu, and asked curiously, "Xuan Degong, General Guan, do people always lie on their sides when they freeze to death?"

Liu Bei and Liu Bei were caught off guard by the question.

Such a strange question is really difficult to answer.

After frowning and thinking for a while, Liu Bei hesitated and said in a very uncertain tone, "People who freeze to death... are probably lying on their sides, right?"

Guan Yu also said, "It should be so."

Now that the times are bad, in the past few years, every winter, Liu Bei and Guan Yu saw many people freezing to death, but they did not pay attention to the fact that when people froze to death, they were sleeping on their sides.

Dead, or lying down to die.

Liu Bei didn't understand why Li Mengxi asked about the dead. He felt that there must be a deep meaning in it, so Liu Bei asked him carefully.

Li Mengxi replied, "This point may be used in sentencing.

If there is a dead body one day, and there is suspicion of freezing to death, you can look at the shape of the body when it died. If it was frozen to death, it must be lying on its side. If it is not lying on its side, someone must have moved the body and threw it on the snow.

Based on this, we can peel off the cocoons and uncover the truth."

Li Mengxi only made a guess, which was derived from the phenomenon that people generally sleep on their sides when it is cold. Li Mengxi himself did not take it seriously because it had not been verified. However, Liu Bei and Guan Yu looked at Li Mengxi,

His face changed slightly.

In the eyes of Liu Bei and Guan Yu, Li Mengxi has become the master of breaking eucalyptus.

Li Mengxi finished writing. What he wrote was...

[What is the maximum capacity of a standard marching tent?]

This is related to the accuracy of overall management.

Suppose that one day, 100,000 refugees come to surrender, and the army rushes to mobilize military tents to respond.

If we cannot accurately know the capacity limit of a marching tent, we cannot calculate how many tents are needed and how much manpower can be accommodated.

Nowadays, the tents in the army are in a mess, with different sizes, and there is no way to verify the statistics. However,

[The tents in the army are of different sizes, so they should be uniform.]

In addition, Li Mengxi also remembered:

[Ultimate Tent Accommodation Method, the manuscript mat is shortened by one-third, and people curl up on it, saving one-third of the length, which can improve space utilization.]

Just sweep up the manuscript so that more people can sleep. It was such a common sense thing that Li Mengxi wrote it down seriously.

Because Li Mengxi discovered that he himself did not know the method of rolling up manuscripts. He inherently believed that a tent could only sleep ten or ten people. He originally thought that even if the tent was full, it would only be a manuscript mat.

It's just next to a manuscript table.
