Chapter 37 Chapter 9 Biologists and Aerospace Engineers

After the "Zheng He" set sail, it went down the southeast along the Pearl River.The farmland on both sides of the strait is beautiful, the crops and vegetables are green, and the land is very rich.On the upper deck, scientific workers leaned on the railing in twos and threes, enjoying the beautiful scenery of Zeguo, a water town in the south of the motherland. There are many ships on the river, and they come and go very frequently, just like cars on the bustling streets of the city.After the ship passed, it dragged a long wave on the river.Compared with the Yangtze River, Yellow River, and Huaihe River in our country, the water of this river can be said to be the clearest.No wonder Fang Yutian looked at the clear water in the river, and expressed emotion to Huang Jingzhi standing beside him:

"Zhenqing, this is probably due to the lush forests in the upper reaches of the Pearl River." Liang Weizhou and Yue Jing also walked from the room to the upper deck at this time.The two of them had long been accustomed to the scenery along the river and didn't care. What they were interested in was the biologist Fang Yutian.When Liang Weizhou saw Fang Yutian on the upper deck, he said excitedly: "Come on, let's go to your room and talk!" This suggestion hit Fang Yutian's heart, and he said "OK, OK" while letting them go to his room.As soon as Yue Jing entered the room, she let out an "ah" and couldn't help taking a step back.Liang Weizhou didn't know what happened, so he hurried in and saw that there was a skull on the table.After Fang Yutian heard the sound, he quickly went in and packed up the skull, and said apologetically at the same time:

"Sorry to startle you. Sit down!" In fact, Yue Jing was not afraid, it was just that she was not mentally prepared just now, and Leng Ding was shocked.She casually picked up a drawing board placed on the table, and there was an unfinished head portrait on the paper clipped on the drawing board.His forehead was steep and his lips protruded, making him uncomfortable to watch.She said strangely: "Why did you draw such a portrait?" "Why, isn't it pleasing to the eye?" Fang Yutian didn't care, he glanced at the packed skull, "Who made his frontal tubercle so obvious, who made his maxillary alveolar process and The teeth are thrusting forward desperately?"

"Oh," Liang Weizhou understood, "You are painting a restoration of this skull, right?" "What are you painting it for?" A puzzled expression flashed across Yue Jing's fair and round face. "I won't tell you first." Fang Yutian smiled slightly, "Yesterday Liang Gong said that we earthlings also paid a huge price in the process of marching into the universe, but what problems did they encounter and what price did they pay? We haven't talked about it yet. Tell me, should Liang Gong and I answer in order?" "Oh, you're still playing tricks!" Yue Jing said with a smile, "Wei Zhou, you can talk about it first, I just want to hear it too."

"Okay, let me say it first." Liang Weizhou couldn't help talking, "There were many such examples in the early days of our earth's space travel, that is, in the 1960s and 1970s. Let me say a few Let me hear it." "On July 21, 1961, when the 'Mercury' spacecraft, which was conducting a suborbital flight test, splashed down on the sea as planned, the supporting ship had not yet arrived. The accidental explosion caused the hatch of the cockpit to open ahead of time. The sea water poured into the spacecraft, and the astronauts on the "Mercury" hurriedly swam out of the cockpit and drifted on the sea, while the spacecraft sank to the bottom of the sea. Later, in Helicopters searching the sea found the astronauts and rescued them one by one."

"On March 19, 1965, when Ascendant 2 was about to return to Earth, the automatic return control mechanism on the spacecraft suddenly failed and could not work. In this case, it was planned to switch to manual control, but due to Missed the scheduled landing position, and had to let the spacecraft fly in orbit again. When the next time it reached the scheduled landing position, the astronauts finally used manual control to lower the spacecraft. However, manual operation is not as good as automatic, and the spacecraft landed in Ural In a snow-covered forest on the western slope of the mountain, there was a difference of more than 800 kilometers from the scheduled landing site. The recovery force near the scheduled landing site found the position of the spacecraft after several hours of searching. Due to the lonely forest traffic It was very inconvenient, and it took them another day to get the astronauts out with a sled."

"Mankind's road to conquer the universe is really not smooth." Yue Jing turned her face to Fang Yutian, "This time it's your turn to introduce the restored statue!" "Don't worry, I will talk about it when the time comes. Mr. Liang hasn't finished yet!" Fang Yutian still didn't give up. Even though Liang Weizhou doesn't like to talk very much at ordinary times, but today this topic suits his taste very much, so he didn't say anything, and started talking like a few treasures: "On March 16, 1966, the orbiting 'Gemini 8' spacecraft, due to the misoperation of the astronauts, turned on the wrong attitude control engine, and the attitude of the spacecraft suddenly lost control and rolled in space. No more. Then, two more unlucky things happened: the generator circuit was short-circuited, and the manual control system failed. Due to these failures, the spaceship, which was originally scheduled to operate for three days, had to return early after flying for only ten and a half hours. ground."

"Apollo 15 also ran into trouble before landing on August 7, 1971. At that time, it burned one of the three main parachutes while draining the remaining fuel from the attitude control engine. Fortunately, the other two main parachutes are still working as usual to ensure a safe landing." Fang Yutian had been listening attentively, and now he said as if expressing his thoughts: "The astronauts in these cases were all saved. Compared with the Tianyuan four, they are very lucky!" Outside, people went to the restaurant to have lunch one after another. Liang Weizhou got up and said:

"Where do they compare with the Tianyuan four who came from afar, as long as they compare with other astronauts in space accidents on the earth, they are very lucky people! I have a few examples in this regard, If you're interested, we'll come back this afternoon." Yue Jing first smiled at Fang Yutian, and then corrected: "I don't care if you're interested in what he said, anyway, I'm here to listen to your talk about portrait restoration." After lunch, Fang Yutian walked on the deck with Huang Jingzhi again.At this time, the "Zheng He" had already sailed through the Shiziyang, and when it reached the Humen area, the river suddenly opened up.After driving out of Humen, in terms of water area, it is already the mouth of the Pearl River.Here, there are about 20 to 30 kilometers between the two sides of the strait. Standing on a boat and looking at the scenery on both sides of the strait, it is already hazy.People who enjoyed the scenery along the river on the upper deck returned to the cabin to rest one after another.

On the way back to the cabin, Fang Yutian told Huang Jingzhi that Liang Weizhou would go to his room in the afternoon to talk about some interesting issues, and asked Professor Huang to come and listen.Huang Jingzhi readily agreed. At 2 o'clock in the afternoon, from the port side of the "Zheng He", Huangmao Island can be vaguely seen, which is a small island in the northwest corner of the Wanshan Islands. Fang Yutian saw Liang Weizhou and Yue Jing coming, so he called Huang Jingzhi who lived next door. Liang Weizhou is a real person, once he saw that everyone was present, he would cut to the chase and talk about it.Yue Jing signaled Liang Weizhou to wait a moment, and then Fang Yutian said:

"This time Wei Zhou has finished speaking, you can't evade any more!" "Xiaoyue, don't worry, I'll talk about it as soon as your one finishes talking." Fang Yutian promised, "Gong Liang, talk to us again." Seeing that Fang Yutian and Professor Huang were so interested, Liang Weizhou immediately started talking.He said: "Well, let me tell you a few more instances where sacrifices were made. "On June 29, 1971, the so-called three-seater 'Soyuz 11', due to the small volume of the cockpit, arranged for three astronauts not wearing space suits to drive in the cabin. Unfortunately, when they started Before returning, when the cockpit and the orbital module were separated, there was an air leakage failure in the sealing plug. As a result, all the air in the spacecraft leaked into space, and three astronauts died due to explosive decompression. Since then, the three astronauts The cockpit was changed to a two-person cockpit, and I never dared to go to the sky without wearing a spacesuit.” Speaking of this, Liang Weizhou showed a very regretful expression.Fang Yutian handed him a cup of tea, and he took a sip before talking about another matter: "On January 27, 1967, 'Apollo 4' was installed on the top of the 'Saturn' launch vehicle. Two old astronauts and a new astronaut were sitting in it for a simulation test. Suddenly, An electric spark set the cockpit filled with pure oxygen on fire. At this time, no matter whether it was from inside the cabin or from the launch pad outside the cabin, the hatch could not be opened quickly. The three astronauts were caught by this accident. The fire burned them alive." No one smoked in the room, but for some reason, Huang Jingzhi felt a sense of dullness. He suggested to go to the upper deck for a change of air, and they left the room together. The ship has sailed through the Wanshan Islands and entered the beautiful South China Sea.Gradually the number of people on the upper deck increased again.You know, except for Fang Yutian, these scientific workers who participated in the Tianyuan Fourth Project sailed in the South China Sea for the first time.For a while, the sea was calm, and the sea was smooth and smooth like a mirror.This is a rare good weather in the windy autumn. The water waves set off by the "Zheng He" are like two ridges of pure white snowflakes floating on the blue ocean.Looking forward, there is an endless ocean of rivers and seas.In the distance, the water is connected to the sky, the sky is connected to the water, the water and the sky are the same color, and there is a vast expanse.Seeing this magnificent scenery, everyone praises the greatness of the sea. Looking at the boundless sea, Yue Jing thought about the events Liang Weizhou just mentioned, and said with emotion: "In front of the sea, in front of nature, how insignificant people seem!" Huang Jingzhi disagreed with her statement: "Man's body cannot be compared with the sea or nature, but with his own wisdom and labor, man is conquering the ocean, the sky, and nature, and has taken the step of marching into the universe. From From this perspective, people are the greatest.” "You look like a philosopher!" After Yue Jing said, she hurriedly covered her mouth with her hands.For fear of giggling in front of Professor Huang. Huang Jingzhi didn't mind, he said calmly: "People who don't understand philosophy can't do science." Not long after, they returned to the room and heard Liang Weizhou continue talking: "On April 24, 1967, the main parachute of the 'Soyuz 1' spacecraft could not be opened before the scheduled landing due to the entanglement of the parachute cord. The veteran astronaut Komarov fell to his death on the spot, and the spacecraft also Crashed." "These astronauts died so badly!" Yue Jing's voice was also a bit bleak. "Actually, these are not the worst." Liang Weizhou's eyes became darker, "In October 1960, when Mars was closest to the earth, that is, when the so-called 'launch window' of Mars opened. , a certain country is preparing to launch a spacecraft to Mars. When the launch order is given, the launch button is pressed, but the ignition device does not start. According to safety regulations, the fuel must be taken out before maintenance, but this will take a long time. They did this. At one command, all kinds of workbenches and ladders moved towards the rocket, and dozens of aerospace engineers and rocket experts opened up various parts of the complex rocket system. Suddenly, the ignition device started again, and the fuel burned crazily Get up, the rocket jumped up and fell down, the entire launch site was engulfed in flames, and hundreds of experts, technicians and soldiers present were burned to death." Fang Yutian had a thoughtful expression on his wide face, and he said in a solemn tone: "Man's path to conquering space has been full of disasters and disasters." Huang Jingzhi narrowed his eyes slightly, as if thinking and summing up: "On the road of human beings climbing the peak of science, there are many such examples. Whenever a new theory appears, someone will immediately practice it. Although the technology was not mature at the beginning, there are still such and such cases. There are even certain dangers, but as long as there is a possibility of success in this technology, there are many brave people who are not afraid of sacrifice and boldly experiment. In the past, this was the case in navigation, and the same is true in aviation; now, space navigation It's still the same." Fang Yutian stared at the porthole and said to himself: "Looking at it this way, it's not surprising that the four people from Tianyuan crashed and died at the gate of our earth." Outside the window, a few albatrosses were flying freely in the high blue sky, and a flock of seagulls flitted across the low sea.As far as the eye can see, there is a vast ocean.Since entering the South China Sea, the "Zheng He" has accelerated its speed, and now it is heading towards the Paracel Islands. The sun gradually sank, and the sea in the west was dyed blood red.Under the afterglow of the sun, the surface of the sea shimmered like a glittering brocade. "Old Fang, don't keep looking out of the porthole, do you want to pass by?" Yue Jing couldn't help laughing as she said. "Why?" Fang Yutian was stunned for a moment, and immediately understood, "Now I'll tell you why I painted restored portraits. In fact, there is nothing wrong with it. It's just that I haven't drawn for a long time and it's a bit rusty, so I brought a portrait. Skull, practice your technique." "What does this have to do with our Tianyuan Fourth Project?" Yue Jing asked. Fang Yutian smiled slightly, and said in a confident tone: "When the remains of the four people in Tianyuan are found in the future, I will draw restored portraits of them." "Didn't it mean that their appearances are all in Bossview's images?" Yue Jing asked again. "By restoring the image, you can verify the wave view image of the copper ball, isn't it also very good?" "You want to find a skeleton from the wreckage of the spaceship?" Liang Weizhou was deeply suspicious. "I don't dare to hope for complete bones." Fang Yutian is unwilling to imagine those impossible fantasies. "If you can find and fish up the wreckage of the spaceship, I hope to find a few bones." "Thousands of years have passed, I'm afraid it has been dissolved in the sea water and turned into nothing!" Liang Weizhou said without thinking. "As long as the airtight cabin where the four of Tianyuan are located is not destroyed, there is always hope that a few bones will be preserved." Fang Yutian is still full of confidence. "With a few bones, can you restore the bodies of the four people in Tianyuan?" There was a smile on the corner of Yue Jing's mouth, and she still seemed not convinced by her expression. "This is not a problem. We can first observe their shape from the copper ball wave view image, and then use the obtained bones as a basis to gradually deduce the shape, size, and position of the bones of the whole body according to the 'organ-related law'. " "That's just a skeleton diagram." Liang Weizhou pointed out immediately. "Don't worry," Fang Yutian said calmly, "Muscles in the human body are attached to the surface of bones by muscle strength, and each muscle has a different and specific attachment point. Its strength and weakness vary. It affects the structure of the bone surface. Therefore, based on the characteristics of the bone surface structure, we can infer the size, strength and attachment point of the muscle. With the shape of the muscle, it is not difficult to describe the body shape." "Why are the four people in Tianyuan so similar to the people on Earth?" Hearing Yue Jing raise this question, Fang Yutian smiled, and there was a bewildered expression in this smile.Because he always believed that the advanced intelligent creatures on other celestial bodies, due to the different evolutionary paths they have experienced, are almost impossible to be the same as our earth humans.Yesterday, Yang Fan told him clearly that the four of Tianyuan are very similar to us!But he was a biologist, and there had to be an explanation for her question.He thought for a while and said: "This may be just an accidental coincidence, but it is not unreasonable to go deeper. We humans can work, first of all thanks to the division of labor between the forelimbs and hind limbs. Without this division of labor, there will be no real labor, and there will be no creation. Human civilization. Since the four people in Tianyuan are members of another civilized society, they must also have the division of labor between the forelimbs and hind limbs, as shown in the image of the copper ball wave view. As for why there are two Eyes, two ears, this is not surprising, if you want to hear the direction of the sound, you must have more than two ears; if you want to see the image of the object, you must have more than two eyes. And big In the process of creating life and human beings, nature always uses the fewest organs to achieve the best results. Therefore, the result of evolution has become two eyes, two ears, two hands, and two legs." They talked so enthusiastically that they even missed dinner time. At dawn the next day, people came to the deck again. The sky in the east is a thin line of white, with a few wisps of dark red clouds floating in the sky.The sky gradually brightened.From the vast sea, a line of red flames spewed out slightly.After a while, this tiny red flame turned into half a fireball, burning in the sea water, which seemed to be boiling.After a while, the fireball slowly broke free from the sea water.A round of red sun, which is round at the top and flat at the bottom, rises slowly from the end of the sea. During breakfast, Captain Li announced to everyone that he expected to arrive at Xisha at 9:00 am. After nine o'clock, the young ones, even the gray-haired Professor Huang boarded the pilot deck with great interest, looking to the south. A gust of north wind blew, and there were layers of waves on the sea. It was Xu Zhenyu's keen eyes to explore the universe. He first saw a white belt on the southern sea.He exclaimed excitedly: "Xisha, that's Xisha!" Everyone looked in the direction he pointed, and it turned out to be the white spray formed by the swell waves hitting the coral island, which indicated that Xinghua Island in Xisha, the base of Tianyuan No. 4 Project, was not far away. Not long after, the palm trees and maple trees on the island can be seen faintly. Xinghua Island finally arrived, and the "Zheng He" was moored at its pier.Ren Sihong and Xu Zhenyu disembarked first, and they will discuss with the local people's government, troops stationed on the island and the weather station to establish a base.
