>Ultra-high-energy cosmic accelerators
我国发现最高能量光子

Chinese scientists have detected a dozen ultra-high-energy cosmic accelerators within the Milky Way, a find that could overturn humanity's understanding of the galaxy and help reveal the origin of cosmic rays, which have puzzled scientists for a century. The findings were based on the observations of China's Large High Altitude Air Shower Observatory, one of the country's key national science and technology infrastructure facilities, which is under construction in Daocheng, in Southwest China's Sichuan province.
由中国科学院高能物理研究所牵头的中国高海拔宇宙线观测站国际合作组近日宣布,中国高海拔宇宙线观测站(LHAASO拉索)在银河系内发现大量超高能宇宙加速器,这一发现可能颠覆人类对银河系的认识,并有助于揭示困扰科学家一个世纪的宇宙射线的起源问题。拉索是国家重大科技基础设施,位于四川省稻城县,目前仍在建设之中。

Scientists led by the Institute of High Energy Physics under the Chinese Academy of Sciences made the discoveries after an 11-month observation using the completed half of the installation.
科学家们使用已建成部分进行了11个月的观测,得出了这一重大发现。

One photon with an energy of 1.4 PeV was detected, the highest value ever observed by humans.
科学家们还记录到1.4拍电子伏的伽马光子(拍=千万亿),这是人类观测到的最高能量光子。

The new discoveries were published in Nature on Monday.
该成果于5月17日发表在《自然》杂志上。

China's fixed-asset investment went up 19.9 percent year-on-year in the first four months of this year, data from the National Bureau of Statistics showed Monday. Fixed-asset investment amounted to 14.38 trillion yuan in the first four months, according to the NBS.
国家统计局5月17日发布的数据显示,1—4月份,全国固定资产投资(不含农户)14.38万亿元,同比增长19.9%。

Compared with the 2019 level, FAI growth came in at 8 percent during the Jan-April period.
与2019年同期相比,1—4月份全国固定资产投资增长8%。

Investment by the state sector went up 18.6 percent during the period, while private-sector investment rose 21 percent.
国有控股投资同比增长18.6%,民间固定资产投资同比增长21%。

On a month-on-month basis, fixed-asset investment rose 1.49 percent in April.
从环比看,4月份固定资产投资(不含农户)增长1.49%。

The FAI includes capital spent on infrastructure, property, machinery and other physical assets.

中国正全力开展新冠疫苗接种工作。根据国家卫健委的最新通报,截至5月16日,全国新冠疫苗接种超4亿剂次,从3亿剂次到突破4亿剂次仅用9天时间。

安徽省和辽宁省最近出现新冠肺炎确诊病例,这在一定程度上加快推动了大规模疫苗接种工作。
