"Huansheng, if Lu Shanlin is approached by Team Cao to crack the reflection of the mirage of the Middle East Asterisk, then he must have the results of his research, doesn't he?" I tried to break free from the fog of history constructed by Huansheng, and tried my best to start making some rational judgments.

Huan Sheng nodded, his eyes flashed with some brilliance, "Lao Chang, Lu Shanlin's research direction is different from mine, he is a standard experimental, he firmly believes that the mirage is an optical refraction phenomenon, the reason why it is difficult for us to find the realistic reflection in the mirage is because the meteorological environment is very different, and the formation conditions are not fixed, so the distance of the refracted object may be far beyond our imagination, and it is not impossible for the body of the reflection to be on the other side of the earth." In addition, because the farther the light travels in the process of refraction, the greater the fluctuation, and the scene we see may be distorted or even superimposed and misaligned. ”

"About five years ago, he spent half a year in the Taklamakan Desert with his students doing a significant experiment. At the northern end of the desert, he erected three metal pillars more than 100 meters high, each with three mast-like crossbars, which were tied with huge red, white and blue flags. Such a flag looks spectacular in the unobstructed desert, and can be easily distinguished by the naked eye from five kilometers away. ”

Near the three pillars, Lu Shanlin built a circular tank more than 100 meters long and half a meter wide, filled with a large amount of clean water, and outside the tank was a series of solar panels and electric heating equipment. The idea was to heat the air around the tank, increase the amount of water evaporation, and use the temperature difference to create a water-rich air mass above the flagpole to create a mirage-forming weather conditions. ”

"Of course, Lu Shanlin has other equipment, and I have already left the team of chasing mirages at that time, and I don't know enough about the specific experimental methods. In short, Lu Shanlin wanted to create a small environment conducive to the appearance of mirages through human intervention, and then find observation points where mirages can be observed, and through the location of observation points and the surrounding climate data, a set of mathematical models for calculating mirage imaging can be calculated. ”

"So Huansheng, is there such a formula, we can also extrapolate backwards, based on the data around the observation point, to infer the actual location of the image body in the mirage?"

"In theory, of course, there is no problem, but in practice, there will be no fewer problems, such as data collection, such as data comparison and analysis, which requires a very large amount of data, and the calculations in it, even with the most advanced computers, take a long time. By the time the results were available, and at the confirmed location, the mirage had already dissipated, and it was impossible to test at all, so to speak, with the current level of technology, this was a paradox. ”

Huan Sheng paused, took a sip of tea, and continued: "After Lu Shanlin erected those poles, it is said that after driving through the desert for four or five months, tens of thousands of kilometers, it took one or two accurate observation points to find the location of the observation points once or twice, and to establish that mathematical model, and because of the differences and changes in the surrounding climate values, the location of the observation points is also dynamic, and the chances are too great. ”

Indeed, the study of physics and mathematics is perhaps the most boring work in the world, and dozens of Chinese New Year's Eve of repetitive calculations sometimes require not only human curiosity, but also tenacious will and a strong desire to conquer.

I thought that the story of Huansheng was about to come to an end, but I didn't expect him to change his words, leaving a big suspense in this story.

"Chang, Lu Zhilin's theories and mathematical models have not been recognized by the scientific community until now, and the papers published have been attacked by his peers, even he himself thinks that there are still many imperfections, but I heard that about two years ago, he interrupted his research, and the research base in the desert was abandoned. ”

Huansheng's words were a bit unexpected to me, with Huansheng's description, how could Lu Shanlin, a persistent mirage chaser, easily give up his research, and what kind of situation would go beyond the difficulties he had encountered?

Huan Sheng looked at my puzzled expression, shook his head with a wry smile, sighed, and continued, "Lu Zhanglin, this person has a very bad temper, and it can be said that he is a hundred times less affectionate than me. The mirage chaser who quit halfway is a betrayal of his career in his opinion, and he never contacts or communicates again, acting like a fellow traveler, of course, the same for me. So I don't know exactly why he interrupted his research, but I heard that in the process of searching for the observation point, there was an accident where people went missing, and several of his students disappeared into the desert. ”

Moreover, it seems that before the experiment was interrupted, Lu Shanlin installed a huge timer on the flagpole, which was more than ten meters long and more than five meters high, and was still customized from Japan, but no one knew what the purpose of this timer was. Forget it, Lao Chang, don't think about it, we will see Lu Shanlin soon, maybe all the doubts will be solved. ”

"Timer?" Huansheng's words made me think deeply.

Before all doubts are far from being solved, the first thing we have is a fatalistic prophecy. It is too appropriate to use the phrase that there is no good wine in wine and no good banquet in the banquet to describe the unexpected hospitality of the Cao team.

I held on to the side of the boat, completely ignoring the sea breeze of five or six levels, my stomach turned over the river and the sea, and I was dizzy and couldn't feel the balance of my body at all. Every shake of the boat was the beginning of a new vomiting for me. Although I have been to the sea a few times before, I have never left the coastline for five kilometers, thinking that I can quickly adapt to life at sea, but when I actually go to the open sea, I understand the challenges.

Huansheng was not much better than me, but he vomited twice when he got on the boat, and then collapsed into the cabin, unconscious. Team Cao had obviously adapted to the rocking of the ship, and looked as usual on the deck. He enlightened me, like me, who has been vomiting on my stomach, and after two days, I will be like a normal person, but Huansheng is sleeping on the boat like this, and it is estimated that he will not be able to slow down for a week.

We were on a 2,000-ton ocean-going research ship, and we heard that we had just carried out an Antarctic research mission, and we were sent here within a few days of resting back at our home port. There was a helipad for a helicopter at the stern of the ship, and that day we arrived in Sanya, and sure enough, in response to our previous concerns, we didn't look at the beach, and we got on the helicopter and sent the research ship, which at this time had reached more than 200 nautical miles southeast of Hainan Island.

Seeing that Huansheng and I were not used to the bumps on the ship, Team Cao did not rush to introduce us to the situation, and stayed on the lookout with the captain all day long, discussing something. There were a lot of staff on the ship, but I didn't see Lu Binglin that Huan Sheng said.

After a night's sleep, the next day the sun was shining on the sea, which was a rare good day recently, and my seasickness seemed to disappear in an instant. On the deck, Team Cao was chatting with a tall, thin bearded man in his fifties, holding a cigarette in his mouth.

The bearded man had a grim expression, as if he was not listening to Team Cao's chatter, and looked at the skyline in a daze. His beard was thick, untrimmed, his cheeks were black and red, he looked weather-beaten, and he wore a large straw hat that he used when he went to the fields in the countryside, which almost covered half of his face.

When Team Cao saw me coming, he hurriedly got up and greeted me, and introduced to the bearded man beside him: "This one is Chang Ye, the consultant in our bureau, an old friend, and the matter of Poyang Lake and Shennongjia is all Chang Ye's handiwork." ”

As soon as the bearded man heard Team Cao's words, a smile appeared on his stiff face, and he also stood up and held my hand.

The bearded hands are very broad and powerful, and the palms are calloused, more like a farmer. Without waiting for him to speak, I asked with a smile: "You must be Professor Lu Lin Lu, I am fortunate to meet you." ”

The bearded man was stunned for a moment, and looked at the Cao team in surprise, "What? Professor Chang, have we met before? Please forgive me, my memory has been very poor in the past two years." ”

"Lao Chang, there is no mention of Professor Lu in the file you received? Team Cao scratched his head, apparently not understanding the mystery of my uncertain prophet.

"Professor Lu, do you remember a professor at Beijing Institute of Technology named Liao Huansheng? I said to Lu Shanlin with a smile.

"Huansheng is here, we haven't seen each other for a few years, it seems that this trip will not be lonely, but there is a lot of noise. Team Cao, let's talk, I'll check the equipment. Lu Shanlin smiled bitterly, stopped talking, and turned his head back to the cabin.

Although Huansheng gave me a preventive injection before leaving, I still couldn't accept Professor Lu's almost unreasonable self-behavior, and the hand I had just shaken was suspended in the air.

Team Cao looked at me embarrassed, and said with a smile: "Professor Lu's temper is a bit weird, but the more knowledgeable people are, the bigger their temper, isn't it?"

I glanced at Team Cao, "Old Cao, you are right in your criticism, it seems that I am too approachable in the team." ”

"Chang, I also have a headache and a foot pain, the East Star incident has made no progress for more than three months, and my mouth has been foaming in a circle, and I have tried all kinds of methods. Team Cao handed me a cigarette, leaned his arm on the railing, and looked at the calm sea.

I lit a cigarette and stood beside Team Cao, "Old Cao, let's talk about the current situation, how many things are not written in the materials, this time it seems that you have used all the resources you can use." ”
