中国建成核光钟：量子精密测量的新跨越

A Nuclear Clock Built in China

A new type of timekeeper, known as a nuclear clock, has been built and successfully operated by Chinese scientists, who say it is one of the most important advances in quantumprecision measurement this century.

Unlike atomic clocks, which rely on the energy transitions of electrons orbiting an atom, a nuclear clock is based on transitions deep inside the nucleus of thorium-229, a rare radioactive isotope. Because the nucleus is far smaller than the atom itself, its transitions are less disturbed by external electromagnetic fields and temperature changes, which is why the device is expected to offer greater accuracy. To drive the transition, the team built its own continuous-wave vacuum ultraviolet laser with a wavelength of 148 nanometres, and it also grew high-quality thorium-doped calcium fluoride crystals from just 1.4 micrograms of the scarce isotope.

The findings were published online in Nature on October 7. Several of the joint first authors are doctoral students born after 2000. Solid-state nuclear clocks are expected to be compact and easy to engineer, making them promising candidates for satellite navigation, deep-space missions and tests of fundamental physics.

一种被称为核光钟的新型计时装置已由中国科学家研制成功并实现稳定运行。他们表示，这是本世纪量子精密测量领域最重要的进展之一。

原子钟依靠绕原子运动的电子的能级跃迁来计时，核光钟则不同，它以稀有放射性同位素钍-229原子核深处的跃迁作为基准。因为原子核比原子本身小得多，其跃迁受外部电磁场和温度变化的干扰更小，所以这种装置有望提供更高的精度。为驱动这一跃迁，团队自行研制出波长为148纳米的连续波真空紫外激光，还用仅1.4微克这种稀缺同位素培育出高质量的掺钍氟化钙晶体。

相关成果于十月七日在《自然》杂志在线发表。几位共同第一作者都是2000年以后出生的博士研究生。固态核光钟有望做到体积紧凑、易于工程化，因而有可能应用于卫星导航、深空探测以及基本物理规律的检验。

守护长征记忆的一趟慢火车

The Slow Train That Keeps a Long March Memory

Every morning in Baiyin, Gansu Province, a slow green train sets off for Changzheng station — the only railway station in China named after the Long March.

The station, built in 1972 to commemorate the Red Army's meeting at Dalachi, serves a line that has been operated by train number 7515/6 for more than three decades. The whole journey covers 94 kilometres, takes a little over two hours and costs just 11.5 yuan, which makes it a lifeline for people in remote villages. Some of the smaller stops along the route have no platform at all; the train simply halts whenever a passenger is waiting to get on.

More than 90 years ago, the soldiers who set out on the Long March were, on average, under 20 years old, and they crossed mountains and rivers on foot for thousands of kilometres. Today, the children who take this train say they owe their peaceful lives to those young soldiers, and that the spirit of the Long March still lives in Chinese hearts. While high-speed trains race ahead, this slow green train quietly keeps a warmer promise — connecting the smallest stops to the wider world.

每天早晨，在甘肃省白银市，一趟绿皮慢火车驶向长征站——那是中国唯一以长征命名的火车站。

这座车站一九七二年建成，用以纪念红军打拉池会师。它所属的线路由7515/6次列车运营了三十多年。全程九十四公里，运行两个多小时，票价仅十一块五，是偏远村庄居民的“生命线”。沿线一些小站根本没有站台，只要有乘客要上车，列车就会停下来。

九十多年前，踏上长征路的士兵平均不到二十岁，他们靠双脚翻山越岭，走了几千公里。今天，乘坐这趟车的孩子们说，他们的安稳生活要归功于那些年轻的士兵，长征精神仍然活在中国人心中。当高铁一路飞驰向前时，这趟绿皮慢火车静静守护着一个更温暖的承诺——把最小的车站与更广阔的世界连接起来。

中国将牵头制定全球冰雪景观标准

China to Lead Global Ice and Snow Standards

China will lead the writing of global standards for man-made ice and snow landscapes, after a new committee was approved to base its office in Harbin, Heilongjiang Province.

According to the Standardization Administration of China, Harbin Ice and Snow World has been appointed to host the secretariat of ISO/TC358, a committee on artificial ice and snow landscapes. This is the first ISO technical body in China's ice and snow industry. The committee, proposed by China, will develop international standards covering the safety, design, construction, operation, maintenance and sustainable development of indoor and outdoor ice and snow structures, and its work will focus on terminology, engineering, safety and low-carbon technologies.

The application was submitted in October 2025 by Harbin Ice and Snow World together with the China National Institute of Standardization, and it was approved on July 20, 2026, after two rounds of voting by ISO member states. Because such parks now appear across the country, from large outdoor sites in the north to indoor ice halls in the south, the new standards should give the fast-growing industry a single set of technical rules and share Chinese experience with the world.

在一个新委员会获批把办公机构设在黑龙江省哈尔滨市之后，中国将牵头制定人工冰雪景观的全球标准。

据中国国家标准化管理委员会消息，哈尔滨冰雪大世界获准承担人工冰雪景观技术委员会 ISO/TC358 的秘书处工作。这是中国冰雪产业领域的首个 ISO 技术机构。该委员会由中国提议设立，将制定国际标准，涵盖室内外冰雪建筑的安全、设计、建造、运营、维护与可持续发展，其工作重点是术语、工程、安全与低碳技术。

申请由哈尔滨冰雪大世界联合中国标准化研究院于二〇二五年十月提交，在 ISO 成员国两轮投票后于二〇二六年七月二十日获批。由于如今这类园区遍布全国，从北方的大型户外场地到南方的室内冰雪馆，新标准应能为这一快速成长的产业提供统一的技术规则，并与世界分享中国经验。
