有日本专家组成的一个研究小组研制出迄今为止制造的精准度最高的原子钟。这台光晶格钟灵敏度极高,能够探测到地球引力发生的变化,允许科学家测量时间的精度达到令人吃惊的17位数。此外,它也可用于大幅改进GPS跟踪系统,探测最小10厘米的高度差。这台新原子钟由东京大学的英敏香取教授以及他的团队在澳大利亚新南威尔士大学维克多·弗拉姆鲍姆教授的帮助下研制。弗拉姆鲍姆表示,光晶格钟就像是一个放在草皮上装有原子的蛋格。“离子时钟通常只有一个原子,你必须等待很长时间,才能达到所希望的精确度。新发明的原子钟可以操 A team of Japanese experts has developed the most accurate atomic clocks ever made. The optical lattice clock is extremely sensitive and capable of detecting changes in the Earth’s gravitation, allowing scientists to measure the time to a staggering 17-digit accuracy. It can also be used to dramatically improve the GPS tracking system to detect height differences of up to 10 cm. The new atomic clock was developed by Professor Min Min Xiang and his team from the University of Tokyo with the help of Professor Victor Flambaugh, University of New South Wales, Australia. Flambbaum said that the light lattice clock is like an egg grid placed on the turf. ”The ion clock usually has only one atom, you have to wait a long time before you can achieve the desired accuracy. The newly invented atomic clock can be manipulated
