德国科学家在9月14日出版的英国《自然》杂志上报道说,他们研制出了临界电流强度高的钇钡铜氧化物超导体,可望大大降低超导线路传输电力的成本。钇钡铜氧化物超导体的临界温度为零下180摄氏度左右,因此它能够用沸点为零下196 German scientists in the September 14 issue of the British “Nature” magazine reported that they developed a high critical current strength of yttrium barium copper oxide superconductors, is expected to greatly reduce the cost of superconducting transmission lines. Yttrium barium copper oxide superconductors critical temperature is minus 180 degrees Celsius so it can be used with a boiling point of minus 196
