又添4种元素！你的元素周期表又要更新了哦！

Get ready to ring in 2017 with a brand new Periodic Table, because four more elements have officially been added to the seventh row: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og).

做好准备吧！2017年你将面对周边全新的元素周期表，因为又有4种元素正式加入第7行了：nihonium（Nh）、moscovium（Mc）、tennessine（Ts）、oganesson（Og）。

We've been hearing about these four new elements since January, but the International Union of Pure and Applied Chemistry (IUPAC) has finally announced that the names have been officially approved, so we've got the go-ahead to tear down all our posters and find some new ones.

从今年一月份我们就听说过这4种新元素了，但国际理论（化学）与应用化学联合会（IUPAC）终于宣布了正式批准其命名，有了公告，我们就可以撕下所有周期表贴图再找些新的换上了。

"Following a five-month period of public review, the names earlier proposed by the discoverers have been approved by the IUPAC Bureau," the organisation announced today.

今天该组织宣布：“经过5个月的公开审议，早先由元素发现者提出的命名方案已由IUPAC批准通过。”

"Keeping with tradition, the newly discovered elements have been named after a place or geographical region, or a scientist," they add.

他们还补充说：“依照传统，新发现的元素都以地方名、地理区域名或一位科学家的名字命名。”

"The ending of the names also reflects and maintains historical and chemical consistency: '-ium' for elements 113 and 115 and as for all new elements of groups 1 to 16, '-ine' for element 117 and belonging to group 17 and '-on' for element 118 element belonging to group 18."

“刚完成的命名也反映并维护了历史和化学的一贯性：第113号和115号元素都有后缀‘-ium’，跟1至16组的所有新元素一样；第117号元素带有‘-ine’，属于第17组；第118号元素有‘-on’，属于第18组。

The teams of Russian, American, and Japanese researchers behind the four new element discoveries were then tasked with naming their respective finds, and in June, their suggestions were officially submitted for review.

发现这四种新元素的俄罗斯、美国、日本科学家团队随即接受了为它们命名的任务，6月份，他们的命名建议正式提交进行审议。

To get to know our four new friends a little better, nihonium is derived from "Nihon", a Japanese word for Japan, and moscovium honours the Russian capital city, Moscow.

为了更深入一点了解我们的新朋友：“nihonium”是由“Nihon”衍生来的，后者在日语中表示日本，而“moscovium”则是为了向俄罗斯首都莫斯科致敬。

Tennessine is named after the state of Tennessee, known for its pioneering research in chemistry, and it marks the second US state to be honoured on the periodic table. The first was California, referenced by californium (element 98).

“Tennessine”是根据田纳西州（Tennessee）来命名的，该州因化学研究成果卓越而闻名，它也是美国第二个在元素周期表中留名的州。第一个是加利福尼亚（California），第98号元素californium就是以它命名的。

Oganesson is named after 83-year-old Russian physicist Yuri Oganessian, and this is only the second time a new element has been named for a living scientist.

“Oganesson”是根据83岁的俄罗斯物理学家Yuri Oganessian的名字来命名的，这也是历史上仅有的第二次以一个在世科学家命名新元素的案例。
