China's natural gas output up 7.1 pct in September******

BEIJING, Oct. 24 (Xinhua) -- China saw an increase in its natural gas output in September, official data showed.

The country's natural gas output totaled 15.7 billion cubic meters last month, rising 7.1 percent year on year, according to the National Bureau of Statistics (NBS).

The volume rose 15.2 percent from that in September 2019, putting the two-year average growth at 7.3 percent.

In the first nine months, China's natural gas output amounted to 151.8 billion cubic meters, increasing 10.4 percent from a year earlier, the NBS said.

Imports of natural gas rose 22.7 percent from a year earlier to 10.62 million tonnes in the same period. Enditem


大家希望的詹姆斯·韦伯太空望远镜(The James Webb Space Telescope ,JWST)将在12月22日发射火箭升空,科技界对它很有可能发觉的宇宙的奥秘激动不已。这台望眼镜的发射,早已延迟了十年之久,成本也大幅度超过预算约90亿美金。好多个小问题来简易了解一下这台深受希望的望远镜吧。

What is the James Webb Space Telescope and when will it launch?

Nasa is preparing to launch a space telescope that will see further into the Universe than anything else ever built.。


The James Webb Space Telescope (JWST) has taken 30 years and $10bn (£7.5bn) to develop, and is being described as one of the grand scientific endeavours of the 21st Century.。

詹姆斯·韦伯太空望远镜(JWST) 的开发设计用时 30 年,斥资 100 亿美金(75 亿英镑),被觉得是 21新世纪最宏伟的科学探索之一。

What is the goal of this telescope?


The telescope will be able to see just about anything in the sky. However, it has one overriding objective - to see the light coming from the very first stars to shine in the Universe.。


These pioneer stars are thought to have switched on about 100-200 million years after the Big Bang, or a little over 13.5 billion years ago.。

这种最开始星系被觉得是在爆发后差不多1亿到2亿光年,也就是大概 135 亿光年前打开的。

Why would we want to see the first stars?


这个由近万个星系构成的图像被称为哈勃超深空(the Hubble Ultra Deep Field),由哈勃太空望远镜在环绕地球400圈后积累影像数据而成。  这一由近万只星系组成的图象被称作哈勃超太空(the Hubble Ultra Deep Field),由哈勃太空望远镜在环绕地球400圈后累积影象数据信息而成。

When the Universe was formed in the Big Bang, it contained only three chemical elements - hydrogen, helium and a smattering of lithium.。


Every other chemical element - including those vital to life, such as carbon and oxygen - had to be forged, or "manufactured", by nuclear reactions at the centre of stars.。


Webb will help us understand the origins of everything we see around us, and how we came to be.。


How does Webb differ from existing space telescopes?



It's much bigger than the Hubble telescope, which has been orbiting Earth since 1990.。

它比自 1990 年至今一直紧紧围绕地球上运作的哈勃望眼镜大很多。

Hubble collects light using a main mirror that's 2.4m (7.8ft) across, while Webb has a primary mirror that's 6.5m in diameter.。

哈勃应用直徑为 2.4米(7.8 英寸)的主镜搜集光源,而韦伯则应用直徑为 6.5米的主镜。

With all the other associated equipment, Webb is about the size of a tennis court. It's so big, in fact, it has to be folded to fit inside its launch rocket.。


But the key aspect of Webb is that it is tuned to detect light that Hubble cannot - in the infrared. This light is invisible to the human eye, but it's the type of light in which the glow from the most distant objects in the Universe will show up.。


When will it launch?


At the moment, Webb - named after James E Webb, the Nasa boss who oversaw the Apollo Moon-landing project - is scheduled to go into orbit on Wednesday 22 December.。

现阶段,这台以承担阿波罗登月新项目的美国nasa厅长詹姆斯·韦伯的名称定名的太空望远镜方案于 12 月 22 日星期三进到路轨。

It will be launched on a European Ariane-5 rocket from French Guiana. The European Space Agency is a partner on the project, and has agreed to take on the responsibility of getting Webb into space.。


How much has Webb cost and why?


Nasa spent $8.8bn on Webb's design and build, and it will put in a further $860m to support five years of mission operations.。

美国nasa在韦伯的制定和修建上耗费了 88 亿美金,并将再资金投入 8.6 亿美金来适用五年的每日任务运作。

The European Space Agency has invested about €700m (£590m) in the project, contributing to two of Webb's four instruments and providing the Ariane launch rocket. The Canadian Space Agency (CSA) also put in about CA$200m (£120m).。

欧洲航天局已在该新项目中项目投资了约 7 亿欧(5.9 亿英镑),为韦伯的四台仪器设备中的两部作出了适用,并出示了阿丽亚娜火箭发动机。澳大利亚航天部门 (CSA) 也资金投入了约 2 亿加元(1.2 亿英镑)。

It all adds up to a figure in excess of $10bn (£7.5bn; €9bn; CA$12.7bn).。

这一切斥资加起來超出 100 亿美金(75 亿英镑;90 亿欧;127 亿加元)。

It's true Webb is years behind schedule, and it's suffered on occasions from poor project management. But some of the money has been spent on technology developments that have had wider application elsewhere - for instance, a measurement tool created for Webb is now used in precision eye surgery.。


For context, Hubble has so far cost close to $15bn in today's prices. Few would doubt its worth after all its discoveries over the past 30 years, and the James Webb Space Telescope is expected to be no less revolutionary.。

目前为止,哈勃以今日的价钱测算的成本费已贴近 150 亿美金。非常少有的人会猜疑它过去 30 年来的使用价值,并且詹姆斯·韦伯太空望远镜预估也一样具备颠覆性。

HK Spisska Nova Ves end Slovan Bratislava's ten******

BRATISLAVA, Dec. 21 (Xinhua) -- In the 27th round of Slovakia's ice hockey Tipos Extraliga, HC Slovan Bratislava's 10-game winning streak came to an end as league newcomers HK Spisska Nova Ves beat them 4-3 on Monday.。

After weeks of smooth sailing, HC Slovan Bratislava ran ashore, losing to HK Spisska Nova Ves in the final minute as Branislav Rapac secured the victory with only 23 seconds left on the clock.。

His teammate Andreas Strauch laid the foundations for the visitors' win with two goals in the first period. At the other end of the ice, Slovan forward Marcel Hascak had his stick in all three goals, scoring the first one and assisting the other two.。

Elsewhere, bottom side MHK 32 Liptovsky Mikulas put up a spirited defense before eventually losing 5-3 to reigning champions HKM Zvolen.。

The game was tied in the first period but the home team's Czech forward Petr Obdrzalek failed to capitalize on his penalty shot. Instead, Zvolen struck again in the final period and stretched the lead to 3-1.。

Liptovsky Mikulas tried to rally later on with two goals, effectively tying the game, but Zvolen did not lose focus and took the lead again in the penultimate minute.。

In other matches, HK Dukla Michalovce lost 3-1 to Nitra, HK Poprad beat Nove Zamky 3-0, HC '05 Banska Bystrica defeated HC Kosice 3-2, and HC Grotto Presov won 3-1 against HK Dukla Trencin. Enditem。
