标题：中国科研人员刷新国际纪录，研发出稳定度极高的铷原子钟
武汉，1月13日 – 中国科学院精密测量科学与技术创新研究院的研究员梅刚华及其团队近日公布了一项重大科研成果，他们成功研制出一款新型铷原子钟，其稳定度刷新了国际纪录。
据梅刚华介绍，这款新型铷原子钟的秒级频率稳定度达到了9E-14，百秒级频率稳定度为9E-15。这一成果的取得，标志着中国在精密测量领域的研究实力再次取得了重大突破。
“1E-14是百万亿分之一，这意味着我们的铷原子钟的频率稳定度在全球范围内都是最高的。”梅刚华在接受采访时表示，“这一成果的取得，离不开我们团队的辛勤工作和不懈努力。”
铷原子钟是一种利用铷原子的振动频率来测量时间的高精度设备，广泛应用于全球定位系统、导航系统等领域。其稳定性能直接影响到这些系统的准确性和可靠性。因此，提高铷原子钟的稳定性一直是科研人员努力的方向。
这次中国科研人员研制出的新款铷原子钟，不仅在稳定性上刷新了国际纪录，也为全球精密测量领域的发展提供了新的可能。这一成果的取得，无疑将进一步提升中国在全球科研领域的影响力和地位。

News Content: Title: Chinese Researchers Break International Record with Highly Stable Rubidium Atomic Clock
Wuhan, January 13 – Researcher Mei Ganghua and his team from the Institute of Precision Measurement Science and Technology Innovation at the Chinese Academy of Sciences recently announced a major scientific achievement. They have successfully developed a new type of rubidium atomic clock with a stability that sets a new international record.
According to Mei Ganghua, the new rubidium atomic clock has a second-level frequency stability of 9E-14 and a hundred-second-level frequency stability of 9E-15. This achievement marks another significant breakthrough in China’s research capabilities in the field of precision measurement.
“1E-14 is one part in a million billion, which means our rubidium atomic clock has the highest frequency stability in the world,” Mei Ganghua said in an interview. “This achievement could not have been made without the hard work and unremitting efforts of our team.”
A rubidium atomic clock is a high-precision device that uses the vibration frequency of rubidium atoms to measure time. It is widely used in global positioning systems, navigation systems, and other fields. Its stability directly affects the accuracy and reliability of these systems. Therefore, improving the stability of rubidium atomic clocks has always been the focus of scientific research.
The new rubidium atomic clock developed by Chinese researchers not only sets a new international record for stability but also provides new possibilities for the development of precision measurement worldwide. This achievement will undoubtedly further enhance China’s influence and status in the global scientific research field.”
