1The birth of the universeObserved universe， its borders are about more than 100 million light- It consists of a large number of Earth is an ordinary planet in the solar system， while the solar system is an ordinary star in the Milky W We have observed how stars， planets， comets， and galaxies produced?The cosmic doctrine， we observed the universe in the early stages of their nurture， focusing on a small， high temperature， great density primordial 15 billion to 20 billion years ago， the primordial fireball Big Bang was the beginning of the history of the birth of the universe where we 01 seconds after the universe， the original big bang， the universe's temperature is about 100 billion Material exists mainly in the form of electrons， photons， Later， the material is the rapid spread quickly lower the 1 second after the Big Bang， down to 10 billion 14 seconds after the Big Bang， the temperature of about 30 million After 35 seconds， to 300 million degrees， and the chemical elements began to take The temperature is falling， the atoms The universe was filled with the gas Gravity， the formation of star systems， star systems after long evolution into today's The sum of the physical Broadly refers to the infinite variety of the eternal development of the physical world， the narrow sense refers to the observation far the largest objects of a certain The latter are often referred to as the observable universe， our universe， the equivalent of metagalactic In February 2003， the US National Aeronautics and Space Administration told the world to publish their research findings about the age of the According to information released by the age of the universe is 7 billion years In November 2003， the international astrophysics research group claimed that the exact age of the universe is 1 billion years The formation of the Earth about 5 billion years The etymology inspected in the Chinese classics the first to use the word in the universe is "Zhuangzi Equality of Things" "Yu" meaning， including all directions， such as East and West "Universe" includes past， present during the day and night， that all the different The corpse of the Warring States Period Jiao said: "up and down the Quartet said Yu， said this to the ancient " And "Yu" refers to the space， "universe" means "universe" is the unity of time and Later， the word "universe" will be used to refer to the objective reality "Heaven and Earth"， "heaven and earth"， "Kuni" with the concept of the universe quite， but these concepts refer only to the space of the "Tube" of the universe together "the word" universe "refers to the time，" integration "(ie，" Kuni ") refers to the space， and closest to the concept of" universe "In the West， the word of the universe called the cosmos in English called Russian кocMoc， called kosmos in German， in French called the They are derived from Greek κoσμoζ， the ancient Greeks to the creation of the universe but produce order from chaos， κoσμoζ its intent is to But in English more often used to represent the word "universe" is the This term In the Middle Ages， a group of people to act together in the same direction towards the same goal as the In the broadest sense， the universitas also said that all ready-made things a unified whole， that is the universe， the the universe and the cosmos is often said the same meaning， the former is the sum of the physical phenomena， while the latter stressed that the overall structure of the universe or Development of the concept of the universe for the development of the concept of the structure of the universe in ancient times， people in a very naive state of understanding of the structure of the universe， they are usually made naive assumptions on the structure of the universe in accordance with their living Early celestial dome in the Western Zhou Dynasty， Chinese people living in the land of China said that the vault of heaven like a pot upside down in a flat earth; later developed for late celestial dome， said that the shape of the earth is arched The 7th century BC， the Babylonians， the heavens and the earth are arched， and the earth by the sea surrounded by its central The ancient Egyptians to imagine the universe in days for the lid， the land of the big box in the bottom of the box， the center of the earth of the N Ancient Indian imagination disc shape of the earth the negative in a few elephants， but as the great Turtle on the late 7th century BC， the ancient Greek Thales， the earth is a huge disc floating on the water shrouded above the vaulted First to recognize that the earth is spherical， the ancient G In the 6th century BC， Pythagoras， from an aesthetic concept that the most beautiful in all the three-dimensional graphics is spherical， advocates of celestial bodies and the earth we live are The notion that later inherited by many ancient Greek scholar， but it was not until after the 1519 to 1522， Portugal F Magellan led the expedition completed the first voyage around the world， the earth is spherical concept was finally
人与环境是和谐相处的，我们生存在地球上，人是自然之子，而不能仅把人看作自然的征服者，大家都知道，人类只有一个地球，地球上的山山水水、动物。植物是人类的细胞，如果我们把它损坏了，破坏了大自然的组织，等于消灭人类。因此，环境要与社会公德联系起来，与实践行为作为人格教育的一项重要内容来抓。每个人都要履行保护环境的责任和义务。 Harmony with the environment is that we live in on Earth， who is a natural son， and not only to natural persons as the conqueror， as we all know， there is only one earth and the mountains on Earth， the Plant human cells， if it damaged， destroyed nature organizations， to the eradication of Therefore， the environment must be linked with social ethics， character education and practice acts as an important element of Everyone must fulfil its responsibilities and obligations to protect the
We live in a universe like slides， generalized speed frame is relative， there is the same absolute speed， if the other is still running quickly， then use the positive direction of negative， and absolute run， then go back in time， time and volume of the object， there is a certain relationship of ants is ten years， but they finished the 100 years of human finished， for ants， too， they see 100 years of vast space， like the earth and the earth we see things outside， the volume of time and speed are absolutely relationship， if the person of 100 meters tall， long life is 1000 years， such as the speed and life， tortoise frames of the universe is a huge universe through， like people， each neuron cell， and not the space-time door， probably guess novel hidden in the depths of the Bermuda triangle， is one of the forces of nature， or in the pyramid， pyramid is probably not， but the deeper diamond Flying isn't human dream， material and material are absolutely contact， and stone， contain CaCO3， By analogy， you say that all matter， they contain more than the matter， small quarks also can find this matter， if the antimatter， like lodestone， then the humanity will use it to fly in the sky， there is the hydrogen plate， sheet metal plates of hydrogen is close to zero and even， quality， less than zero， the density of titanium and not hypothesis， maybe one day will be Light is a kind of particle， quality， human beings use solar energy density is the light of using thermal energy and convert it to recycle， light energy of particles in the future is boundless， more remote， light particles will replace Like the universe we live inside a slide， a broad speed is relative， as there is an absolute speed， if someone is still running fast， then use the positive direction of the negative throttle， and certainly large， then could return， the volume of the object and the time also there is a relationship， the life span of a decade ants， but they finished the 100 years of human things done， for the ants it is also 100 years， they see the majority of space， is like the Earth and the Earth we see something other than the existence of a volume of absolute time and velocity relationship， if one 100 meters long， it's life-span of 1000， such as the turtle on the speed and life， the universe The one is through， the vast universe， just like human neurons， each connected to the door is not a novel space-time suspect， may be hidden in the Bermuda Triangle， a deep， was formed by the forces of nature， or in the pyramid， the pyramid may be diamond， just not digging Flying is not the dream of the human， material and substance， are all there is absolute， and the stone has links contain CaCO3， and so on， you can say have links to all substances， they also contain more than Quark small matter， if this material can find anti-matter， the same as magnet， then the man will use it flew up into the sky， there is the board hydrogen， hydrogen is a metal plate sheet， the quality is close to 0 or less than 0 ， density greater than titanium， this is not a hypothesis that may later be realized some Light is also a particle， there are quality density， human use of solar energy is the thermal effect of the use of light， convert it into electricity， then use the energy of light particles is infinite， in the more distant future， when the light particles will be replaced H
People at all times in life to deal with geographic Geographic knowledge around in our lives， good grasp of the useful life of the geographical knowledge， can effectively resolve the practical problems of life， and enhance capacity to deal with And accompanied by the development of computer technology， GIS (Geographic Information System referred to as GIS) to come into The so-called GIS， it is a specific kind of spatial information systems， computer hardware and software， the part or the whole of the Earth's surface related to the geographical distribution of space data acquisition， storage， management， analysis， show that the technology Geographic information systems in many countries has been widely used， especially in mapping and cartography， resource management， urban planning， disaster monitoring， transportation， logistics， census and other Geographic information systems and networks is the Internet combined with GIS technology and the development of a network of GIS data integration platform， it can be carried out through the network of spatial data browsing， We call WEBGIS Geographic Information System Application in the population census is to B / S form of the development site， the user can easily and quickly in the Internet， the use of the Geographic information systems in the population census of the application systems need to achieve the focus is on data collection， processing and display， on the one hand， the user input data， the system automatically on the database for statistical analysis of data， and then on the map display data in a particular On the other hand， the user operation on the map page shows the map in accordance with the relevant data user Geographic information systems in the population census of the application system development using asp language line， use the js， css， such as the development of technology for collaborative development， database use sql Processing to generate the map， the use of third-party software MapInfo， MapX MapXtreme can be nested in the use of Visual Studio The key technology is the map loading， database access and so The use of B / S structure of application systems developed by the census is the Browser / Web Server / Application Server / Data Server composed of four-tier Web Server and Application Server which is inserted into the secondary development of software development and Different functions on different layers， layer and layer to play a different Keyword: WEBGIS， MapXtreme， the level of development
