2024考研英语同源外刊:“室温超导”将如何改变世界?
Superconductors that can operate under normal ambient temperature and pressure have long been considered the holy grail of physics, replete with promises of revolutionizing everything from electricity transmission and transportation to electronics and nuclear fusion, all due to the miracle material's property of offering virtually no resistance to the passage of electric current.
长期以来,能够在常温常压下工作的超导体一直被认为是物理学的圣杯,因为它有望彻底改变从电力传输到电子和核聚变等一切领域,所有这一切都归功于这种神奇材料的特性,因为它几乎不对电流的通过产生任何阻力。
In India, with its creaking electrical infrastructure, electricity transmission losses are as high as 30 percent! In a world dominated by superconductors, such transmission losses would be non-existent, freeing up a lot of spare capacity that can then be idled to reduce carbon emissions from India's fossil fuel-reliant power plants.
在印度,电力基础设施摇摇欲坠,电力传输损耗达30%!在一个由超导体主导的世界里,这种传输损耗将不复存在,从而释放出大量闲置产能,以减少依赖化石燃料的印度发电厂的碳排放量。
Of course, with superconductors freely available, Maglev (Magnetic Levitation) trains would become ubiquitous. These trains rely on two sets of electromagnets, where one set keeps the train afloat on designated tracks using the magnetic repulsive force while the other propels the train forward.
当然,随着超导体的任意使用,磁悬浮列车将随处可见。这些列车依靠两组电磁铁,其中一组利用磁斥力使列车漂浮在指定的轨道上,而另一套则推动列车前进。
Given the lack of contact between the train and the track, Maglevs are quite energy efficient. With the advent of room-temperature superconductors, however, the cost of operating such trains would fall drastically, given the lack of electricity losses within the electromagnets.
由于列车与轨道之间没有接触,磁悬浮列车非常节能。不过,随着室温超导体的出现,由于电磁铁内没有电力损耗,这种列车的运营成本将大幅下降。
If superconductors become ubiquitous, everything from electric motors to everyday appliances would become a lot more energy efficient. In fact, room-temperature superconductors might well be a requirement for humanity as a whole to reach its zero-carbon targets.
如果超导体无处不在,从电动汽车到日常家电,这一切都将变得更加节能。事实上,室温超导体很可能满足人类作为一个整体实现其零碳排放目标的要求。
One of the most defining implications of room-temperature superconductors would likely emerge in the field of nuclear fusion. If a huge amount of current can be passed through a given wire without resulting in waste heat from electrical resistance, extremely powerful electromagnets could be created at reasonable costs.
室温超导体较具决定性的影响之一可能会出现核聚变。如果大量的电流可以通过给定的导线,而不会导致电阻产生余热,那可以用合理的价格制造出功率极大的电磁铁。
These magnets could then be used to confine plasma into a minuscule space, providing the requisite impetus to jump-start a nuclear fusion reaction and the attendant promise of near-limitless energy.
这些磁铁可以将等离子体限制在一个极小的空间内,为启动核聚变提供必要的动力,并随之带来近乎无限的能量。
