The sky is beautiful and mysteriousThe stars and boundless, no you are in the universe around watching, you'll find all around of stars are visible (star), there are red 6974, blue, yellow, white, and the stars... and will form a constellation, some animal sign, somewhat like the natural objects like, like the mythology, and the characters... it's so beautiful!And, of course, there are not only beautiful in the sky, and you are in the universe around watching, you'll find all around of stars, light and dark, there are small and dark, in addition to see the mysterious UFO puzzle. Dark and mystery, black holes, but also for cosmic mystery...) on a layer of mysterious universe is a beautiful and mysterious place!The sunThe sun is a ball of fire burning in the center of the solar system, and the earth and its nine brother moves round the sun can greatly, almost under the million. The sun is very hot, surface temperature thousands of degrees Celsius, the temperature and thermal center!The sun has now has 50 million years, scientists predict it can also exist 50 million years. If the sun were destroyed, that human? Don't worry, that's already mastered the human is very high science and technology in the universe, another corner of my own earthThe earth is the third planet in our solar system, was the fifth row in earth is human homes, is a blue planet. Earth's land, 29% 71% ocean. The earth is the only planet in the solar system for life, but also the planet at the planet to mankind to explore for humans to live only in the earth is constantly rotating around the sun, at the same time in rotation. The earth revolves round the sun to 365 days a week, about a week to rotate about 24 hours. The earth is 6,400 km, radius about the distance from the sun about million earth is a satellite, that is the universe, who will shine fever stars, called the are generally, is very bright, but also has many a weak light, or have than the earth. Our sun is a the brightness of the stars, we can give stars on level set. 6 the stars can barely seen such as below, 7 is invisible. From June 5, such as began as such, 3, 4, 2, 1, 0-1, 2 -, etc... wait. DengBi The stars are visible 6974 are different color, different color represents different temperature. The highest temperature is blue and red stars grouped into constellations and all were 88 constellation

Beautiful and mysterious Star Star of the vast, vast, endless. If you do around the universe, you will find scattered all around the stars (visible to the naked eye of 6974), red, blue, yellow, white and ....., More stars will form a constellation, the constellation as some animals, like some natural and some appliances, like, as well as the myth of people ...... really beautiful! Of course, the stars are not only beautiful, and mysterious. If you do around the universe, you will find scattered all around the star, bright, dark, big, small, dark ...... In addition, see East and West. Ufo mystery of the mystery, the mystery of black holes, dark matter and antimatter mystery of the universe as it is ...... add a layer of mystery. Of the universe, is also a beautiful, mysterious place ah! Sun The sun is burning a big ball of fire, in the center of the solar system, Earth and its brother 9 rotating around the sun. The sun a lot, can be installed almost 1,300,000 under the earth. The sun is very hot, there are several thousand degrees Celsius surface temperature, the temperature of the center would also like it hot! Sun now has billion years old, scientists can also predict the existence of 50 million years. If the destruction of the sun, then how human beings do? Wait, then the human is very high already mastered the science and technology, already in another corner of the universe to build their own homes. Earth The Earth is the third planet of the solar system, according to the size of the fifth row. Earth is home of mankind, is a blue planet. Earth, 29% of the land, 71 percent of the ocean. The Earth is the only planet in the solar system suitable for living the life of the planet, is also to the human exploration of the planet, the only planet fit for human habitation. In the Earth's rotation around the sun kept at the same time also their rotation. The earth around the sun about a week, 365 days a rotation of about 24 hours a week. Earth's radius is about 6,400 km, the distance from the sun, about million meters. Earth has a satellite that is the moon. Stars In the universe, who can own light-emitting heat of the stars, known as the star. Stars are generally very, very bright, but there are a lot of light is very weak, or smaller than Earth's. Our sun is a star. The star's brightness varies, we will be able to set the star rating. 6, and other stars can barely see, 7 and so on can not see the following. 6 from the beginning, and so on, and so on the order of 5, 4, 3 and so on, such as 2, 1, and so on, such as 0, -1, and so on, -2, and so on ... ... than the first-class. The stars visible to the naked eye up to 6974. Stars have different colors, different colors represent different temperatures. Just like the blue stars and red the highest minimum temperature. A number of stars into constellations, the day a total of 88 constellations

太简单了！看着：Promote the development of the productive forces is the most contemporary computer positive factors, it has gone down to almost all areas of human life and production, raises economic structure, social structure and people's lives. Promote the development of the productive forces is the most contemporary computer positive factors, it has gone down to almost all areas of human life and production, raises economic structure, social structure and people's lifestyles dramatically. In a short span of 40 years, more than 4,000 of its application on all industries, more than 5,000 multiple uses, but also the continued development of new applications. These applications can be grouped into the following categories : one, terms this is the earliest computer applications. In modern scientific research and engineering, there are various complex mathematical problems, if the manual calculation, not only time-consuming effort, but difficult to provide timely and accurate data. High-speed computers and large-capacity, and other features to address these huge, complex calculations provided possible. In weather forecasting, astronomy research, irrigation design, structural analysis of atomic, biological molecular structure analysis, satellite orbit calculations, the research and development of many spacecraft, show that the computer unique advantages. Second, information management According to statistics, 80% of the current total global installed for information management, although the application of formula in this regard is not complicated, but a great volume of data. Such as finance, accounting, management, administration, education, research, medical, personnel, records, materials, and other aspects of a substantial need for timely analysis and processing of information in order to provide a basis for decision-making. In today's era of information explosion, it is difficult to perform this task has been artificial, the computer has become an important tool for information management. In information management, we are experiencing the electronic data-processing services from a single to a database-based management information system, and to databases, and methods for the model-based decision support system development process. Third, the process of using computers to control a dynamic process control, command and coordination, not only can reduce the intensity of the work, improve work efficiency, and to improve control of the accuracy, quality results. For example, in car manufacturing, have computer-controlled assembly, transmission, production lines, technicians need to be good procedures into the computer processing task, the production can in no case automatically. In addition, computer control of chemical in the production, traffic, satellite and missile launch many plays an irreplaceable role. 4, ancillary computer system can support a better accomplish various tasks, such as : computer-aided design (CAD) is the use of computers to help design personnel circuit design, architectural design, mechanical design, aircraft design, design work, raising the speed and quality of design. Computer-aided manufacture (CAM) is the use of computers to carry out the management and operation of production equipment to improve product quality and production efficiency. Computer-assisted test (Cat) is the use of computer help product testing, test automation to achieve and improve testing accuracy. Computer-aided instruction (CAI) is the use of computers as teaching media and tools to help teachers improve the quality and efficiency of teaching process. It is a teaching methods, education ideas and the education system changes. 5, artificial intelligence artificial intelligence (AI) is a vast new computer applications field. Scientists are studying how to make a computer simulation the human brain to carry out understanding, learning, analysis, reasoning, and other senior thinking activities for the computer with more human intelligence, to identify the environment and adapt to the environment, automatic acquisition of knowledge, problem-solving, in order to use computers in certain areas of mental work automation. Computer applications not only improve the efficiency and quality of work, but it is being addressed in the past that are beyond the capability of the problem. Currently, a computer multimedia technology for the development of various information media control center, audio-visual equipment associated with voice and Mau-way dissemination of information, computer applications to be extended to the family closer to the people learning and entertainment areas. The development of the computer network technology perfect combination of computers and communications, particularly Internet网, has spread to dozens of countries in the global network of tens of thousands, millions of computers linked together and communicate to the people of the world, the global sharing of information resources made inestimable contributions. 搞定！～
