第二篇
Superconducting Ceramic(陶瓷)
An underaround revolution beqins this winter. With the flip(轻击)of a switch,
30,000 homes in one part of Detroit will soon become the first in the country to receive
electricity transmitted by ice-cold high-performance cables.Other American cities are
expected to follow Detroit's example in the years ahead,which could conserve enormous
amounts of rower.
The new electrical cables at the Frisbie power station in Detroit are revolutionary
because they are made of superconductors.A superconductor is a material that transmits
electricity with little or no resistance.Resistance is the degree to which a substance resists
electric current.All common electrical conductors have a certain amount of electrical
resistance.They convert at least some of the electrical energy passing through them into
waste heat.Superconductors don't.No one understands how superconductivity works.It
just does.
Making superconductors isn't easy.A superconducting material has to be cooled to an
extremely low temperature to lose its resistance.The first superconductors,made more
than 50 years ago,had to be cooled to -263 degrees Celsius before they lost their
resistance.Newer superconducting materials lose their resistance at-143 degrees Celsius.
The superconductors cable installed at the Frisbie station is made of a ceramic material
that contains copper,oxygen,bismuth(秘),strontium(锶)and calcium (钙).A
ceramic is a hard,strong compound made from clay or minerals.The superconducting
ceramic has been fashioned into a tape that is wrapped lengthwise around a long tube filled
with liquid nitrogen.Liquid nitrogen is supercold and lowers the temperature of the ceramic
tape to the point where it conveys electricity with zero resistance.
The United States loses an enormous amount of electricity each year to resistance.
Because cooled superconductors have no resistance,they waste much less power. Other
cities are watching the Frisbie experiment in the hope that they might switch to
superconducting cable and conserve power,too.
What is the benefit of the revolution mentioned in the first paragraph?
A.With a flip of switch,electricity can be transmitted,
B.Other American cities can benefit from the high-performance cables.
C.Great amounts of power can be conserved.
D.Detroit will first receive electricity transmitted by the new electrical cables.
