新华社武汉７月１３日电（记者 黄艳）近日，中国科学院武汉物理与数学研究所高克林研究员领导的囚禁离子研究组，经过１０年努力，突破了系列关键技术，成功研制出我国首台基于单个囚禁钙离子的“光钟”，成为世界上少数几个掌握此项技术的国家。

    The xinhua news agency wuhan July 13 (Reuters)（Reporter HuangYan）recently，The Chinese academy of sciences and mathematics physics institute of wuhan GaoKeLin researchers leadership trapped ion of the research team，After ten years of hard work，Broke through the key technology series，Successfully developed the first in China based on a single imprisoned the calcium“Light clock”，As the world a few master the technique of the country。

    时间频率标准是人类生产和科学活动的基本条件。高克林介绍说，每一次时频精度的提高，都使人们在更深的层次上认识物质世界。“秒”的定义是时间标准的基础，目前通用“秒”的定义是以原子在微波波段上的跃迁为标准的。而“光钟”则是利用原子在光波波段上的跃迁为标准的。

    Time and frequency standards is the human production and scientific activity basic conditions。GaoKeLin introduced said，Each time the time-frequency accuracy，Make people in the deeper level the recognition of the material world。“seconds”Time is the definition of the foundation of the standard，Gm now“seconds”The definition of the atoms in the microwave band is the transition as the standard。and“Light clock”Is to use light wavelengths atoms in the transition as the standard。

    “由于光学频率比微波频率高出４到５个数量级，因此在相同跃迁谱线线宽的条件下，光钟的不确定精度将优于微波钟１００到１０００倍。通俗地讲就是用它计时精度更高。”高克林说。

    “Due to the optical frequency than microwave frequency than four or five orders of magnitude，So in the same transition wide spectrum under the condition of irrelevant，The light of the clock not sure precision microwave clock will better than 100 to 1000 times。Generally speaking with it is time a higher precision。”GaoKeLin said。

    此外，“光频标”技术不仅能提高计时精度，还能优化精密仪器制造、卫星定位等技术。

    In addition，“Light frequency standard”Technology can not only improve the precision of the time，Still can optimize precision instrument manufacturing、Satellite positioning technologies。

    今年６月３０日，我国与全球同步进行闰秒调整。这多出的１秒，是靠原子微波钟测量的，它的计时测量可达上万年不出偏差。而原子“光钟”比原子微波钟又要精准许多，是人类无限追求时间精确度的产物。

    June 30,，Our country and global synchronously leap second adjustments。This extra 1 second，Is the clock by atomic microwave measurement，Its timing measurement can reach tens of thousands of years a deviation。And atomic“Light clock”Atomic clock and microwave than precise many，Human is the product of infinite pursuit time accuracy。

    据了解，目前掌握此项技术的国家有美国、德国、英国、加拿大、奥地利和日本。据悉，国际计量协会正在考虑重新定义时间基准，这项技术有望为我国在世界时间标准的定义上争得一定话语权。

    According to understand，Have the technology in countries with the United States、Germany、British、Canada、Austria and Japan。It is reported，International measurement association is considering to redefine the time benchmark，The technology for our country in the world is expected to time standard definition of fiercely on certain right。
