Venus is one of the eight planets in the solar system. It is the second planet in the sequence from near to far from the sun, with a distance of 0.725 astronomical unit. It is the closest planet to the earth (Mars is sometimes closer). China called it Chang Geng, Qi Ming, Taibai or Taibai Venus in ancient times, Venus in Roman mythology and Aphrodite in Greek mythology. Period of revolution is 224.7438+0 Earth Day.
2. What are the historical records of the mystery of the market on Venus? As far as human beings know, the natural environment of Venus is much worse than that of Mars.
Its surface temperature t is as high as 500T, and carbon dioxide in the atmosphere accounts for more than 90%. Huge corrosive acid rain often falls, and it often suffers from severe thermal storms that are more violent than the typhoon 12 on the earth. Venus is surrounded by thick clouds, so that nearly 20 probes launched from the earth in the past 20 years (1%0- 198 1) still fail to recognize its true colors.
In the 1980s, photos sent back by American probes showed that there were a large number of towns on Venus. According to analysis, there are 20,000 city fairs on Venus, which are in the shape of a "triangular pyramid".
Each city is actually just a giant pyramid without doors and windows, and there may be a population underground; These 20,000 giant pyramids are arranged in the shape of a big horse wheel, with a big city at the center and small cities around them connected by a radial avenue. Researchers believe that these pyramid-shaped cities can effectively avoid high temperatures during the day, cold and storms at night.
Soviet scientist Nikolai? Ribin Chekhov first revealed the discovery of the urban market on Venus at a scientific seminar in Brussels, Belgium. 1989 65438+ 10, the Soviet union launched the probe.
The detector is equipped with radar scanning equipment that can penetrate the dense atmosphere, and it also discovered the great secret that Venus has 20,000 towns. At first, people were afraid to conclude that this was an urban market. They think there may be something wrong with the detector, or a mirage caused by atmospheric interference.
However, after in-depth study, people are convinced that these are the remains of the city and speculate that they were left by intelligent creatures. However, these intelligent creatures have long since disappeared.
Dr. Ribin Chekhov pointed out at the meeting that we are eager to find out who distributed these cities on the surface of Venus. These cities are great cultural relics. The Soviet scientist introduced in detail: "In those cities built in the shape of horse wheels, the central axis is a metropolis.
According to our speculation, there is a huge radial road network connecting all the cities around it. "Most of those cities have collapsed or are about to collapse, which shows that they have a long history," he said.
There is no life on Venus now, which means that the life there has long been extinct. Due to the extremely harsh environment on the surface of Venus, it is impossible to send astronauts there for field trips.
However, Dr. Ribin Chekhov stressed that the Soviet Union will try to see the faces of those cities with unmanned spacecraft, no matter how much it costs. 1988, Soviet cosmophysicist Alexei? Republika Srpska announced that Venus also has a "face stone", just like Mars.
Scientists speculate that Venus and Mars are a pair. He is my brother, and both have experienced the tragic fate of the destruction of civilization. Scientists also say that Venus, 8 million years ago, experienced the present evolution stage of the earth and should have intelligent life.
Later, there was more and more carbon dioxide in the atmosphere of Venus, so that the greenhouse effect became more and more intense, leading to the loss of water vapor, and finally the environment of Venus was no longer suitable for biological survival. So far, people have found traces of civilized activities on the moon, Venus and Mars, and even some broken walls have been found on the surface of Mercury, which is closest to the sun.
There are pyramid-shaped buildings on the earth, the moon, Mars and Venus. After connecting these, people think that the earth is not the starting point of solar system civilization, but its destination.
3. The research history of Venus Before the space probe detected Venus, some astronomers thought that the chemical and physical conditions of Venus were similar to those of the Earth, and the possibility of finding life on Venus was greater than that of Mars.
In the late 1950s, astronomers first observed the surface of Venus with radio telescopes. Since 196 1, the Soviet Union and the United States have launched more than 30 probes to Venus, from close observation to landing detection.
Venus has a larger orbit than Mercury. When the maximum distance angle is in the west (to the right of the sun) or in the east (to the left of the sun), it seems that it is twice as far from the sun as mercury.
Venus is one of the brightest objects in the sky, and the best time to observe it may be when the sun is just below the horizon. It must be noted that you should never look directly at the sun with your eyes.
When the sun goes down, Venus goes down later, and it is located on the left side of the sun. Venus rises before the sun rises, at this time on the right side of the sun. You can easily tell Venus, which is bright and slightly yellow.
When Venus is in a crescent shape, it is most appropriate to observe it with binoculars. At this time, Venus is located between the maximum angular distance and the lower conjunction point. At the lower conjunct, Venus lies between the earth and the sun, so we can't see it. Pay attention to adjusting the focal length of the telescope so that it can observe distant objects.
Venus is an inner planet. If you look at it through a telescope from the earth, you will find that its phase has changed. Galileo's observation of this phenomenon is an important evidence to support Copernicus' theory about the solar center of the solar system.
Besides the sun and the moon, Venus is the brightest star in the sky that can be seen by naked eyes, reaching -4.4 at its brightest, which is 14 times brighter than Sirius, the brightest star in the whole day. Venus is adjacent to the earth, its diameter is about 4% smaller than that of the earth, its mass is 20% lighter and its density is low 10%.
Theoretically, Venus has an iron-nickel core with a radius of about 3 100km, with a mantle in the middle and a crust outside. Because it is very similar to the earth in size, density, quality and appearance, it has the reputation of "twin sister" of the earth.
Planets of the solar system's space exploration began with Venus. Since the 1960s, the former Soviet Union and the United States have devoted great enthusiasm and exploration competitions to uncovering the secrets of Venus. So far, more than 40 probes have been sent to or passed through Venus, and a lot of scientific information about Venus has been obtained.
1On August 27th, 962, the United States launched Mariner II and arrived near Venus on February 27th, 1962+14. Spaceborne microwave radiometer measures the temperature in the deep atmosphere, and infrared radiometer measures the temperature at the top of clouds.
The results of magnetometer measurement show that Venus' magnetic field is very weak and there is no radiation belt around it. 1June, 967 12, the Soviet Union launched the "Venus" No.4 spacecraft, and entered the atmosphere of Venus on June, 65438+1October 18 of the same year.
The lander of "Venus 4" has a diameter of 1 m and weighs 383 kg. The outer surface is covered with a thick high-temperature resistant shell, and the design limit pressure is 25 atmospheres. After the lander enters the atmosphere, it unfolds the parachute, slowly falls under the action of the parachute, and the detection data is sent to the orbital module in time, and then returns to Earth.
When the lander descended to 24.96 kilometers from the surface of Venus, the signal stopped transmitting. It is estimated that the lander was crushed by the high pressure of Venus. The launch time of "Venus 5" is1969 65438+1October 5, and its design is very close to that of "Venus 4", but stronger.
During the descent of the lander, 53 minutes of detection data were obtained. When the lander descends to about 24~26 kilometers from the surface of Venus, it is damaged by atmospheric pressure, and the pressure at this time is 26. 1 atm.
Venus 6 was launched on 1969 65438+ 10/0, and reached Venus on May 17 of the same year. The lander descended to a distance of 10~ 12 km from the surface of Venus.
1970, 17 In August, the Soviet Union launched Venus 7 and arrived at Venus on February 1970 and 15. The lander of the spacecraft can withstand 180 atmospheric pressure, so it successfully reached the surface of Venus and became the first human messenger to visit Venus.
The returned data shows that the temperature is as high as 470 degrees Celsius. The atmospheric composition is mainly carbon dioxide, with a small amount of oxygen, nitrogen and other gases.
At this point, mankind unveiled the mysterious veil of Venus. Venus's environment is complex and changeable, the sky is orange, and it often rains with sulfuric acid. A flash of lightning actually lasted 15 minutes! On September 9th, 1978 and September 4th, 14, the former Soviet Union launched "Venus1"and "Venus 12", both of which successfully landed in Venus, and the working hours were1/kloc respectively.
Especially when Venus 12 descended to Venus on February 26th, 65438, frequent lightning and thunder rumbled over Venus were detected, and only when it descended to 5 kilometers away from Venus 1 1 surface, it recorded 1000 lightning and one lightning. The former Soviet Union launched the Venus probe "Giant" on 196 1 1 24, and crashed due to the failure of the launch vehicle when it started in space. Venus 196 1 was launched on February 12, 2000. The probe that successfully flew to Venus weighed 643kg, and Venus II was launched on February1965165438+1October 12 and 5.
Nevertheless, scientists in the former Soviet Union think that there is still something to gain, because the first battle that can directly "hit" Venus was successful. 1967 65438+1October 12, the "Venus 4" probe was successfully launched. It arrived at Venus in June 65438+the same year 10, and released a lander to Venus. During its 94-minute passage through the atmosphere, the atmospheric temperature, pressure and chemical composition were measured.
1969, "Venus 5" and "Venus 6" were launched and once again broke into Venus' atmosphere for exploration. The probe finally landed on the surface of Venus. Due to the damage of hard landing instruments and equipment, it was impossible to detect the surface of Venus. 1970 On August 17, the probe Venus 7 was successfully launched. It passed through the dense clouds of Venus, braving high temperature and blazing heat, and achieved a soft landing on the surface of Venus for the first time.
"Venus 7" measured that the atmospheric pressure on the surface of Venus is at least 90 times that of the Earth, and the temperature is as high as 470℃. On September 9th, 1978 and September 4th, 14, the former Soviet Union launched "Venus 1 1 2", both of which landed in Venus successfully, working for 1 10 minutes respectively.
Especially, during the descent of Venus 12 to Venus on June 5438+February 2 1 day, lightning and thunder were detected frequently over Venus, and it only descended at a distance of1/km from the surface of Venus.
4. Pen brand introduction The new rural brand ordinary iridium pen, Hefei Golden Pen Factory, was designed and put into production in 55 years and changed to Foziling brand in 80 years. It was rated as provincial excellent and ministerial excellent. Mainly sold to rural areas. Hefei Golden Pen Factory completely stopped production in 2002, and now all products are in the past inventory.
Venus has Shanghai Venus Beijing Venus, and Beijing Venus Shanghai moved to Beijing in 52. Shanghai Venus changed TV production in 1970s. Venus in size is a famous product of Beijing Golden Pen Factory in 1950s, and most of them are Beijing Venus in the market. Venus 26 is all the inventory in the past. After the bankruptcy and reorganization at the end of last year, Beijing Golden Pen Factory tried to resume the production of a batch of Venus 28, but it seems to have stopped production at present. Venus 26 Taobao is the cheapest 10 yuan (Venus Retail Department is also 10 yuan), and Venus 28 is generally sold around 28 yuan, with a lot of goods.
Hua Fu (predecessor of hero), Guan (predecessor of Youlian), Venus and Doctor were the four early brands of the national pen.
Later, in addition to the immortal Venus, Dandong Bailing Jinlong, Harbin Youlian, Hefei Lily of the Valley, Guangzhou Youth, Tianjin Changhong and Nanjing Astronomy were all famous.
