Underground Coal Fires Coal burning deep underground in China, India and Indonesia is threatening the environment and human life, scientists have warned. These large scale ______ (51) blazes (火焰) cause the ground temperature to heat up and kill surrounding vegetation, produce greenhouse gases and can ______ (52) ignite (点燃) forest fires, a group of scientists told the annual meeting of the American Association for the Advancement of Science in Denver . The resulting ______ (53) of poisonous elements like mercury can also pollute local water sources and soils, they warned. “Coal fires are a global disaster,” said Associate Professor Glenn Stracher of East Georgia Collage in Swainsboro, USA. But ______ (54) few people know about them. Coal can heat up on its own, and eventually catch fire and burn, if there is a continuous oxygen supply. The heat produced is not caused to ______ (55) and under the right combinations of sunlight and oxygen, can trigger spontaneous (自发的) catching fire and burning . This can occur underground, in coal stockpiles, abandoned mines or even as coal is transported. ______ (56) fires in China consume up to 200 million tons of coal per year, delegates were told. In ______ (57), the U.S economy consumes about one billion tons of coal annually, said Stracher, ______ (58) analysis of the likely impact of coal fires has been accepted for publication in the International Joomal of Acoal Ecology. ______ (59) underway, coal fires can burn for decades, even centuries. In the process, they release large ______ (60) of greenhouse gases, poisonous fumes and black particles into the atmosphere. The members of the panel discussed the ______ (61) these fires may be having on global and regional climate change, and agreed that the underground nature of the fires makes them difficult to ______ (62). Ultimately, the remote sensing and other techniques should allow scientists to ______ (63) how much carbon dioxide these fires are emitting (释放) 。 One suggested ______ (64) of containing the fires was presented by Gary Colaizzi, of the engineering firm Goodson, which has developed a heat-resistant grout (灌浆),which is designed to be pumped into the coal fire to ______ (65) the oxygen supply.

? ? ? ? ? {{B}}The Hyper-X{{/B}} ? ?The Hyper-X (超音速飞机) recently broke the record for air-breathing jet planes when it traveled at a Hypersonic speed (超音速) of seven times the speed of sound. That’s about 5,000 miles per hour: At this speed, you’d get around the world -flying along the equator (赤道) - in less than 5 hours. ? ?The Hyper-X is an unmanned, experimental aircraft just 12 feet long. It achieves hypersonic speed using a special sort of engine known as a scramjet (超音速冲压式喷气发动机). ? ?For an engine to burn fuel and produce energy, it needs oxygen. A jet engine, like those on passenger airplanes, gets oxygen from the air. A rocket engine typically goes faster but has to carry its own supply of oxygen. A scramjet engine goes as fast as a rocket, but it doesn’t have to carry its own oxygen supply. ? ?A scramjet’s special design allows it to obtain oxygen from the air that flows through the engine. And it does so without letting the fast-moving air put out the combustion (燃烧) flames. However, a scramjet engine works properly only at speeds greater than five times the speed of sound. ? ?A booster rocket (助推火箭) carried the Hyper-X to an altitude of about 100,000 feet for its test flight. The aircraft’s record-beating flight lasted just 11 seconds. That brief journey on March 27 makes a major milestone on the way to a new breed of very fast airplanes, says Werner J. A. Dahm of the University of Michigan in Ann Arbor. In the future, engineers predict, airplanes equipped with scramjet engines could transport cargo quickly and cheaply to the brink (边缘) of space. Such hypersonic jets could carry passengers anywhere in the world in just a few hours. ? ?Out of the three experimental Hyper-X aircrafts built for NASA, only one is now left. The agency has plans for another 11 -second hypersonic flight, this time at 10 times the speed of sound. |
