Live Wilderness Adventure

"Cough cough."

The icy air Bi Fang couldn't stop coughing. When he raised his head again to look at the live broadcast room, he suddenly found that the live broadcast room, which was full of barrages, suddenly became refreshing, like a pine tree shaking off the snow.

Strange, why is no one talking all of a sudden?

For a long time.

[Fuck, Lao Fang is alive! 】

[It's over, I just prayed that my roommate will be single for a lifetime in exchange for the peace of the gods, and now my roommate is going to be single for a lifetime]

[Roommate: ? 】

[Roommate: I **** thank you]

[Fantastic, the avalanche actually survived! Who else! 】

[It's over, I just screamed too loudly, my mother asked me why I didn't sleep. 】

[Brilliant, brother, you are the best! 】

"Survived! Survived! They're all right, God, they're all right!"

Inside the Arctic Circle, Erwan hugged Lennon's shoulders tightly, jumping and jumping.

"Yes, yes, God bless good-hearted people." Lennon stroked his beard and laughed.

Etienne ran around the open lake and shouted: "It's amazing, they're amazing! Oh hoo!"

In the brightly lit building, the employee on duty immediately contacted Li Yawen and told him the good news as soon as possible.

"Boss, Fang Shen is on the air!"

In the living room, Li Yawen, who saw Bi Fang safe and sound, clenched his fist and hammered the table: "Damn, I knew this kid wouldn't hang up so easily. Damn it, my blood pressure was all done to me."

He opened the drawer and took the antihypertensive medicine with boiling water. Yao Xuehui sat on the chair and let out a sigh of relief. The woman beside him stroked his chest to help him calm down.

"This renegade son does something out of tune all day long. If he has this kung fu, he can advertise his own brand better than this! It's maddening me."

"Oh, it's okay, it's okay, you have a lot of things to do. You are angry when the child has something, and you are also angry when there is nothing. You're afraid it's not made of balloons."

Inside the brightly lit building, the sound of items shattering and low roars rang out from time to time.

"What happened to the supervisor? The stock fund fell? Or did you find that the child is not yours?" In the exact same situation, it was replaced by Little B and asked Little A.

Xiao A looked at Bi Fang, who was scanning the environment on the screen of his mobile phone, and smiled: "Probably the business plan that we just joined together went bankrupt before it even started, but what does this have to do with us, we are just workers, If the company makes money, you can’t get it, and if the company loses, it won’t go bankrupt and lay off employees.”

Little B was stunned for a moment, as if he had been connected to the second vein of the governor, he slowly put down the document in his hand, and picked up the mug beside him.

The smashing sound continued. Xiao A and Xiao B listened to the noise in the office, looked up at the sky with coffee in hand, took a sip of coffee and spit out a mouthful of hot steam.

Every time he fishes, a boss loses his dream.

[Lin Chang gave the anchor spaceship*10--pay me for sleep! 】

[She is dying, why didn't the second big guy sleep in the middle of the night, the reason was because of him! 】

[Speaking of what is going on in this cave! Why is there a cave! 】

[Fang Shen, you finally stop pretending, urban superpower! 】

[I have a showdown, I will stop pretending, and take out the transforming device, yes, I am the light! 】

The audience glanced around with Bi Fang's perspective, and found that the space they were in was not small, almost comparable to a small bus.

A cold mist spit out, Bi Fang sat on the ground and took a deep breath to explain: "Just now, we encountered an avalanche. Except for the two missing Sherpa guides, everyone in the team was in a stable physical condition, except for some There's nothing wrong with the bruises."

What can fly without wings? What can be hit without a fist? What can no eyes see?

This is a riddle that has been around since medieval Europe.

The answer is an avalanche.

Avalanche, also known as the White Grim Reaper.

When an avalanche occurs, the snow keeps collapsing down the mountain from the height of the mountain by gravity, with extremely fast speed and great impact, and often flattening the ground wherever it goes.

According to statistics, avalanches are the biggest natural risk of fatal accidents in winter outdoor sports, no one!

Sitting on the snow wall, Bi Fang was very fortunate that there have been many avalanches on Mount Everest, and the Khumbu Glacier was the hardest hit area, and it happened almost always in the early morning. This is mainly related to the topography of the Khumbu Glacier.

When the cohesive force inside the snow on the hillside cannot resist the "traction" of its gravity, it slides down, causing a large amount of snow to collapse. The Tianshan Snow and Avalanche Research Station of the Chinese Academy of Sciences once found that avalanches are most likely to occur on slopes with a **** of about 40 degrees, which coincides with the topography of the Khumbu Glacier.

Once you are in danger, waiting for rescue is almost impossible. If you really wait, your body has already turned into a part of the glacier and was buried here. Like the story Bi Fang told earlier, it may last a century. Later, it will be re-exposed to people with the movement of the glacier.

After the audience on the screen heard that it was Yingtou Bingpo who guarded Bi Fang and everyone, they could hardly believe that this was actually true.

[Mountain God Appearance, this must be the Mountain God Appearance! 】

[Damn it, this is too awesome]

[It is true that good people have good rewards? 】

"I demonstrated avalanche survival before, but I didn't expect it to happen. There are usually three reasons for avalanche fatalities - physical trauma, suffocation and hypothermia. There are also corresponding lifesaving methods, one is to escape before the avalanche stops, and the other is to To prevent all being buried, the third is to reduce the time for the trapped to be buried.

Under normal circumstances, an avalanche cannot kill people, but the cause of death is the low temperature and lack of oxygen after being buried. But snow also contains life-saving oxygen. Ideally, after being buried, raising your arms to create a breathing space can effectively prolong the survival time. If I had broadcasted it earlier, you would have seen that what Sirius did just now, a very standard way of self-help. "

Bi Fang put his hands on his chest, suffocation is different from ordinary suffocation. Once buried tightly, there is no certain escape skills to expand the space, and the lungs can hardly expand. Many avalanche victims suffocate not because there is no oxygen, It is caused by the inability of the lungs to expand.

"We are very fortunate that there are many types of avalanches based on the physical properties of the snow and where the snow layer breaks, but there are basically two types of avalanches, dry avalanches and wet avalanches."

Bi Fang grabbed a handful of snow from the snow wall on the side and squeezed it with his hands. The amazing thing was that the snow did not gather into a group, but was still powdery and scattered from his fingers, as if it was dry flour.

"What we encountered was a dry avalanche. Friends in the south may not have any feelings, but those in the north must have encountered such a situation. The snow was as dry as flour, unable to gather, and it was impossible to have a snowball fight. This is because the temperature in the north is winter. Too low, the air is dry, and the dry avalanche is similar."

"When the moisture content of the snow is less than 1%, it is generally considered to be a dry avalanche. When a dry avalanche occurs, due to the low viscosity of the snow, a large number of snow particles collide with each other in motion, and will be suspended in the air to form white smoke. . This kind of avalanche will be very spectacular from high altitude, it's too dark today, but your night market mode should see it clearly."

Indeed, many viewers nodded secretly. Because of the altitude problem, the drone did not fly high, and it was almost face-to-face with an avalanche.

The rolling snow waves stretched for hundreds of meters, and the sky was filled with white smoke and dust, almost obscuring the sky.

"The high-speed smoke will compress the surrounding air, forming a powerful air wave, destroying everything along the way. When the air wave is killed, the real avalanche will follow, and the snow will cover everything."

[So how lucky is this, laugh and cry]

[Dry and wet~www.readwn.com~ I guess the wet avalanche must be more lethal! 】

"That's right." Bi Fang smiled.

"When the moisture content exceeds 1%, it is a wet avalanche. Wet avalanches mainly occur in the stage of temperature rise. The temperature rises and the snow melts. Increase. The infiltrated snowmelt water is often easily re-frozen into ice crystals, changing the shape of the particles inside the snow, and the high temperature induces local collapse of the snow surface. The collapsed snow slides down the slope, and the speed will become faster and faster. Convoluted snow gradually forms a snowball.

As a result, a large number of snowballs tend to appear on the slopes before an avalanche occurs.

Eventually, the accumulated mass of snowballs broke the calm slide of the snow, causing an avalanche. In the process of descending, the volume of the snowball continues to increase, and it also carries the melted soil and rocks on the surface, which is much more destructive than dry avalanches. "

Bi Fang paused, exchanged air a few times before continuing.

"If you think about this kind of avalanche, you know how dangerous it is. The rocks involved are no less powerful than the rocks that are blown up in the storm. .. you know."
