Why do you want to wear red overalls for desert inspections?

He has been exploring the extremely harsh natural environment many times, and he knows the danger of being alone. In particular, as the captain of the scientific expedition team, he clearly announced the discipline: "There must be more than two people to go out during the expedition." Why did he violate his scientific research discipline? His disappearance, his sacrifice, the mistake is to go out alone.

In addition, he also stressed that in the strange and easy to lose directions, you should insert road signs along the road. This time, he went east to find a well, and he took a strange road, but did not insert a road sign.

His temporary decision led to the lack of water for the expedition team and the subsequent tragedy.

In order to save state funds, Peng Jiamu went out to find a well, so he disappeared in the desert. His spirit of public and selflessness is always worthy of learning by future generations and will always be worthy of admiration for generations to come.

However, the disappearance of Peng Jiamu should also cause people to reflect.

No one is perfect. In the interview, I also heard many friends regret for him: he has repeatedly explored in the extremely harsh natural environment, and he knows the danger of being alone and going out alone. In particular, as the captain of the scientific expedition team, he clearly announced the discipline: "There must be more than two people to go out during the expedition." Why did he violate his scientific research discipline? His disappearance, his sacrifice, the mistake is to go out alone. In addition, he also stressed that in the strange and easy to lose directions, you should insert road signs along the road. This time, he went east to find a well, and he took a strange road, but did not insert a road sign. In addition, during the interview, someone told me that the expedition team departed from Urumqi, Peng Jiamu was scheduled for May 3, 1980. In Peng Jiamu's view, on this day, the preparatory work for the inspection has been completed, and it is necessary to start, and to seize time and work is the first.

However, May 3 is Saturday. Many of the members of the expedition team are in Urumqi, hoping to start on Monday, May 5, so that they can spend Sunday with their families in Urumqi. Especially for this outing, it will be a month or two. Many people expect to arrange their home affairs on Sunday. The home of Peng Jiamu is not in Urumqi. He did not consider the reasonable demands of the players, or insisted on starting on the morning of May 3. He was the captain and the deputy dean of the Xinjiang Branch of the Chinese Academy of Sciences. The players also obeyed his decision.

Also, after completing the vertical crossing of Lop Nur, arriving at Malan, Peng Jiamu proposed to advance eastward, which was not included in the original scientific investigation plan. The starting point of Peng Jiamu is of course very good. You can take the road to the east of Lop Nur. However, the expedition team left Urumqi on May 3 and went through Lop Nur on June 7. It has been living in the wild for more than a month. The players are very tired and eager to return to Urumqi to rest. Besides, there was no plan for the Dongjin investigation. Many of the players did not make a move at home, and some had already arranged other jobs. The players once again considered that Peng Jiamu was the captain and the deputy dean of the Xinjiang Branch of the Chinese Academy of Sciences, and he still obeyed his decision.

It is precisely because Dongjin is a temporary decision made by Peng Jiamu in Malan, so the preparatory work is very hasty, and the difficulties on the Dongjin route are underestimated, so it will only occur after the arrival of Kumukuduk. The tragedy of Peng Jiamu going alone to find a well in order to solve the water shortage problem occurred.

Peng Jiamu’s mistake lies in excessive self-confidence

Another example is that the drivers told me that the Xinjiang Branch of the Chinese Academy of Sciences had a very unreasonable rule at that time. The fuel consumption of the car and the loss of tires and machinery were calculated according to the number of kilometers traveled. However, if you drive 100 kilometers in the rugged Lop Nur, how can you treat it 100 kilometers on a straight asphalt road? The fuel consumption of automobiles and the loss of tires and machinery are obviously completely different. In particular, there are many crystal blocks of salt at the bottom of Lop Nur, which are hard, sharp and sharp, which makes the tires of the car lose a lot. The drivers once reported to Peng Jiamu, but Peng Jiamu did not solve it because his vice president was not in charge of administrative work.

In addition, the researchers working with Peng Jiamu in the expedition team thought that Peng Jiamu had a wide range of knowledge, which is his advantage, but he is mainly studying plant viruses after all. For all aspects of the Lop Nur comprehensive scientific investigation, he does not Everything is on the line. As the leader of this scientific expedition, he should try his best to listen to the opinions of various researchers, and Peng Jiamu did not do enough.

Therefore, Peng Jiamu’s mistake lies in his excessive self-confidence and his lack of opinions. He often underestimates the difficulty. If the advanced figures are separated from the masses, they are like the locomotives leaving the long train. The disappearance of Peng Jiamu, technically, is due to the lack of special color work clothes that must be worn in the field.

Five years after the disappearance of Peng Jiamu, the warrior Yan Maoshu, who was the first drifting Yangtze River, was wrecked in the Yangtze River rafting expedition. I flew from Shanghai to Sichuan for an interview. Later, in the article "A little red in the green bush", I compare the death of Yan Maoshu with Peng Jiamu and compare it:

In the summer of 1980, when the news of Peng Jiamu’s disappearance in Lop Nur in Xinjiang came, I immediately rushed there to participate in the search. When I was sitting on a helicopter and flying over Kumuduk, the location of the accident, I saw that the yellow sand was long and boundless, and even the "solitude of the desert" was never seen in my eyes. in.

In the desert inspection according to regulations, you should wear red overalls.

Searching again and again, nothing was achieved. The Air Force dispatched more than 30 sorties, flying for more than 100 hours, and there was no trace of Peng Jiamu. I remember, on the plane, an Air Force soldier said to me with exclamation: "Peng Jiamu is wearing a whitewashed blue work cloth overall, which is not easy to find in the desert. According to regulations, it should be worn in the desert. Work clothes.

If he wears red overalls, the plane doesn't need to look for it again and again..." His words left a deep impression on me.

On July 24, 1985, the first warrior of the Yangtze River, Yan Maoshu, died at Tongtianhe. I went to Sichuan for an interview. According to the public security department, at 2 o'clock on the afternoon of July 24, Tibetan herders in Yushu and Batang Township of Qinghai Province saw the "Dragon's Passage" rubber boat and the body of the Yan Mao Book. When the sun was setting, the two Tibetans in Benda Township, Luoshou District, Shiqu County, Sichuan Province, also saw the body of Yan Maoshu drifting along the river. On the 25th and 26th, there were also people witnessing... In just a few days, so many Tibetans along the river accidentally discovered the murder of the book, because the 尧茂书 wearing a special "BJ-1 type Insulation immersion suit, can float on the surface of the water, and the color is bright red. "A little red in the green clumps" is very easy to attract people's attention.

Although "red" is "a little bit", why is it particularly striking in "the green bushes"?

This is because red, green and blue are the three primary colors of light, and the primary colors give the most vivid feelings to the human eye - nature is colorful, and the three primary colors are formed by mixing in different proportions. The human eye is able to distinguish colors because it has three color-sensitive units of red, green and blue. Different colors give the three color sensing units different degrees of stimulation, so the human eye can distinguish the five colors. The three primary colors are only to stimulate a color-sensing unit in the human eye, and this stimulation is extraordinarily strong, so the resulting visual perception is the most vivid.

It’s not enough to just color itself. A little red falls into the "red ocean" and it is difficult to find. The "color contrast" between the background colors must be increased. American Luki is an advertising expert who has done a series of "color contrast" experiments in order to highlight the main image and text in the advertisement. He found that in terms of red, the red color contrast on white is the strongest, followed by yellow bottom red, green bottom red, and blue bottom red.

Oh, because of this, climbing Everest and the Antarctic expedition, people dressed in red. The white ambulance is painted with a red cross - red on white.

It is precisely because of this, desert investigation, river exploration, to wear red clothes - yellow red, green red.

As for the recycling cabin of China's artificial earth satellite, it is painted orange-red, which is also for easy identification in the ocean - blue and red.

If Peng Jiamu asks a team member to go east with him to find a well, if Peng Jiamu wears red overalls when he goes out, the tragedy will not happen. Even if you lose it for a while, it is easy to find, so you don't have to spend so much manpower and material resources to find it again and again.

Of course, Peng Jiamu’s tragedy has solidified into history and cannot be changed. The tragedy of Peng Jiamu reminds people that they must not go out alone during scientific expeditions; in scientific investigations, they must wear prescribed work clothes.
