Nuclear power 1 Nuclear power can come from the fission of uranium plutonium or thorium or the fusion of hydrogen into helium. Today it is almost all uranium. The fission of an atom of uranium produces 10 million times the energy produced by the combustion of an atom of carbon from coal. By 1993, there'd been 109 licensed

1.分类 车用内燃机(internal combustion engine,根据其将热能转变为机械能的主 要构件的型式,可分为活塞式内燃机和燃气轮机两大类。前者又可按活塞运动方式 分为往复活塞式内燃机(reciprocating engine)和旋转活塞式内燃机两种。往复 活塞式内燃机在汽车上应用最为广泛,是本课研究的重点

Background Carbon monoxide( co)is a colorless odorless gas produced by incomplete combustion of carbonaceous material CO is formed as a by-product of burning organic compounds
