Could it be when the original ancestors of the pile group activities around the campfire, and today we are still shining on the Olympic stadium? Prior history of human use of fire can be traced back 100 years, the fire started all human civilization, and even created mankind itself. Prometheus is unique because "theft" and subjected to pay homage to the hero, and fire by rubbing sticks Suiren is more simple and realistic. Ancient Olympic torch during the Peloponnesian dusty city-proclaimed "sacred dsc alarm truce" message, the modern Olympic Games Torch 1928 is officially lit stadium in Amsterdam. dsc alarm After the 1936 Berlin Olympic Games, the torch relay has become the harbinger of each Olympic Games and Overture. People devoted a infinite wisdom, effort and emotion, hoping in peace, unity and fraternity of the Olympic spirit around the world Passing the torch.
When the parabola along the symmetry axis of rotation, you can get a paraboloid. This is the "take Firearms" geometry. Parallel light after reflection can be parabolic, "focus", the mirror of the received radiation energy is highly concentrated. We know that the sun 150 million dsc alarm miles away the light toward the Earth's atmosphere perpendicular to the top and the sun per square meter will accept the 1368 watts of radiation, called the solar constant. dsc alarm Since the atmosphere and clouds obscured the sun irradiation intensity to the ground after will reduce sunlight at different latitudes and seasons are quite different. Flame lit mirror must have adequate lighting area and at the sun, the temperature of the focal part of the torch reached the ignition point. This is why when not lit torch encountered cloudy, sunny weather will only enable the pre-mining a good fire. From everyday life to a satellite dish and solar cookers reflecting telescope, we can often see large and small parabolic in the "sky looked." The searchlight put the light on the focal point of a parabolic mirror, which projected parallel rays.
Today more than 90% of human society is still using energy from burning. Regardless of how the Olympic torch "sacred" to burn on Earth must satisfy three elements. That is fuel, oxidizer and temperature, known as the "fire triangle." In 1772, French chemist Lavoisier first revealed the secret of fire, the oxidation theory proposed combustible substances. Burning is strongly exothermic chemical reaction process and fast luminous, higher ignition temperature of the fuel "forced fire", causing bond breaking molecules occur between atoms exchange and recombination in the combustion zone and combustion, heat released so After the oxidation reaction to continue the removal of the ignition source "self-sustaining" is carried. Olympic torch not like laboratory Bunsen burner as "hot dull" and should be colorful and bright. Olympic Games have used gunpowder, sulfur, resins, naphthalene, olive oil, hexamethylenetetramine do torch fuel, Berlin, dsc alarm London, Melbourne Olympic torch fuel into the main stadium have chosen magnesium, can emit dazzling brilliant though, But Mars scattered scenes that burns athletes arm urged the people to improve on the torch. 1972 Munich Olympics for the first time will be compressed by 24% and 76% propane, butane loaded into a liquid fuel in the tank to make the torch, after the election of liquefied gas into the Olympic torch. In fact, any flame burning substances are gaseous. Liquid evaporation before combustion must first solid combustion is released after pyrolysis volatile components reacted. Therefore, the shape of the flame in the wind always dsc alarm flashing jump, erratic it. Press the "appropriate scale" complete combustion flame is almost colorless, it is flame carbon particles as ten million little "filament" radiate light and heat. Smoke is "carbon residue" excessive characterization burning.
Almost every Olympics host country will desperately, odd meter is full, so that the torch relay extraordinary. In addition to taking the legs to run, from the bicycle, canoe, caravans, cars, trains, dsc alarm ships and planes to the supersonic Concorde, from horseback, camel, dog sledding to ski jumping and skydiving, the Olympic dsc alarm torch across thousands of miles The trip is almost exhausted human means of delivery. Here supreme mission is to ensure dsc alarm the torch going through "eighty-one difficult" does not go out, or we need to re-"back Buddhist sutras," the. 1976 Montreal Olympics, a heavy rain extinguished the torch Olympic Stadium, the venue under the supervision of Boucher dsc alarm ear so he took out a lighter "illegal dsc alarm lit" flame-known story, this is the real reason for stalling the rain will "fire triangle "The temperature dropped to below the ignition point. Water is second only to the specific heat capacity of liquid ammonia per kilogram of water by 1 degree Celsius rise to absorb 1,000 calories, and the heat of vaporization of water at 100 degrees is absorbed by the water rises from 0 degrees to 100 degrees dsc alarm 5 times the heat required, and no wonder fire department water as the best extinguishing material. 2004 Athens Olympics, the stadium winds blew out the Pana Xin ng Olympic officials dsc alarm lit the torch relay in the world, this is because "fire triangle" in the "fuel" was taken away, but the wind was too late to add. Therefore, the basic principles of the torch is designed to "fire triangle" consolidate and strengthen.
1996 Atlanta Olympic Torch dual flame structure, the gas from the tank in the "two-pronged" all the way "big flame" shine the torch tip and despite wind and rain, and the other way "small dsc alarm flame" hiding "big flame "following" wind wall "in dsc alarm the" recharge your batteries "and" escort "so that the" main flow "ready to receive" small flame "uninterrupted ignited. Sydney Olympic torch in 2000 to 65% butane and 35% propane as fuel, the use of the flame back to the heat pipe insulation, to overcome the pressure of liquid fuel tank caused by lower fuel vaporization endothermic, and use a metal foil made of highly heat torch shell on top to prevent rain water vaporization. According to the test, torch 65 kilometers per hour winds and driving rain still burning. As meticulous care of each Olympic Games special "torch dsc alarm seed" safety lamp, it is also to create the most secure burning "small environment", the "fire triangle" into the "iron triangle."
Underwater Sydney Olympic dsc alarm torch relay is bold and romantic dsc alarm attempt, biologists in the Great Barrier Reef Duncan 4-meter-deep water diving torch 3 minutes to start the engine, creating a "fire and water blend" is a great spectacle. In order to ensure a smooth discharge of gas in the deep water to form a stable combustion zone, the fuel tank must meet very high pressure, because there is no oxygen combustion underwater torch must "own" pre-mixing of oxygen and fuel, and ignited main light emission Fuel magnesium. dsc alarm On the ground of this torch burning temperatures exceeding dsc alarm 2,000 degrees Celsius, brightness up to 35,000 candles. While underwater torch complicated manufacturing process, but the basic principle is not difficult to demonstrate, China University of Technology Laboratory fire reproduce once underwater torch burning process.
Entering the era of human spaceflight ever tempted dsc alarm heroic hearts and impulses, trying to extend the Olympic torch into space. 1976 Montreal Olympic Games ingenuity, Pana Xin ng Stadium in Athens torch from Olympia direct "transfer" to the North American continent. This is a special holographic sensor signals and for collecting the flame ionization energy for storage, and then converted to acoustic signal code transmitted via satellite dsc alarm to Ottawa, dsc alarm and then through the ground receiver will demodulate the acoustic signal, and finally converted to the corresponding dsc alarm The laser beam enkindle. dsc alarm This "high tech" means although recently like "God's gift" but much criticized, just five days before and after the process dsc alarm has a negative long-awaited public Moreover, intercontinental delivery lost the "fire" of the entity only "Fire" message is too vague and deviate from the original intention dsc alarm of the torch relay. 1996 Atlanta Olympic organizers are much more realistic idea, they envision the torch to send the shuttle, but for security reasons, NASA has approved only carry Columbia extinguished torch. We might imagine that if the flame burning on the space shuttle is really what the scenario would be no convection of hot and cold gas, the flame will no longer be a steady upward "flames" weightless dsc alarm environment, and gradually expand and become a ball bleak "fireball."
2008 Beijing Olympic torch's biggest dsc alarm "bright spot" is on the world's "third pole" Everest. At an altitude of 8844 meters, "roof of the world", often at minus 40 degrees Celsius temperature, dsc alarm wind speed reached 10, only a third of the oxygen content at sea level. But the torch with advanced heat recovery function, design and dual fuel premixed flame device is fully capable of big shine in such a harsh harsh natural conditions. The real difficulty is that the torch and television personnel backpack weight limit life span, which is a group of Granville group biliary dsc alarm system engineering. When the torch on top of the earth hula burning, the world will witness the history of the Olympic torch relay and an unprecedented feat.
The most ambitious of the pattern and the most magnificent scenes Olympic Games, the opening dsc alarm ceremony than remarkable. This is an era of organizational capacity and civilized standards of human society logo. The torch is lit the opening ceremony of "finishing touch." As the main stadium beautiful flames into the sky, "Olympic Dragon" will be "broken and fly".
Could it be when the original ancestors of the pile group activities around the campfire, and today we are still shining on the Olympic stadium? Prior history of human use of fire can be traced back 100 years, the fire started all human civilization, and even created mankind itself.
