中国为海军建造核反应堆测试版本
📖 逐句对照翻译
China has built a land-based test version of a nuclear reactor for a large warship.
中国已为大型战舰建造了一座陆基测试版核反应堆。
The development is the clearest sign yet that Beijing is moving toward producing the country’s first nuclear-powered aircraft carrier.
这一进展是迄今最明确的迹象，表明北京正朝着建造该国首艘核动力航空母舰的方向迈进。
This information comes from a new study of satellite imagery and Chinese government documents provided to the Associated Press.
这一信息来自一项对卫星图像和美国联合通讯社获得的中国政府文件的新研究。
Why is this development important?
为什么这一发展很重要？
There has long been talk that China is planning to build a nuclear-powered aircraft carrier.
长期以来，一直有传言称中国计划建造一艘核动力航空母舰。
But the recent research by the Middlebury Institute of International Studies in California is the first to confirm the country is working on a nuclear-powered movement system for a carrier-sized surface warship.
但加利福尼亚州明德国际研究所最近的这项研究首次证实，该国正在为航母大小的水面战舰研发核动力推进系统。
China’s navy is already the world’s largest in terms of numbers.
中国海军在数量上已经是世界最大。
China's navy has also been developing quickly.
中国海军也一直在快速发展。
Adding nuclear-powered carriers to its fleet would be a major step in realizing its hopes for a force capable of operating around the globe.
将核动力航母加入其舰队，将是实现其建立一支能够在全球范围内运作的部队的希望的重大步骤。
Nuclear carriers take longer to build than conventional carriers.
核动力航母的建造时间比常规航母更长。
But once nuclear carriers are in operation, they are able to stay at sea for much longer because they do not need to refuel.
但一旦核动力航母投入使用，它们就能在海上停留更长时间，因为它们不需要加油。
In addition, there is more room on board for fuel and weapons for aircraft.
此外，舰上还为飞机的燃料和武器提供了更多空间。
Nuclear carriers are also able to produce more power to run advanced systems.
核动力航母还能产生更多电力来运行先进系统。
Right now, only the United States and France have nuclear-powered carriers.
目前，只有美国和法国拥有核动力航母。
The U.S. has 11 in total, which permits it to keep multiple strike groups deployed around the world at all times, including in the Indo-Pacific area.
美国共有11艘，这使其能够始终在全球各地部署多个打击群，包括在印太地区。
But the Pentagon is increasingly concerned about China’s modernization of its fleet, including the design and building of new carriers.
但五角大楼越来越关注中国对其舰队的现代化改造，包括设计和建造新的航母。
China currently has three carriers, including the new Type 003 Fujian, which was the first both designed and built by China.
中国目前拥有三艘航母，包括新建的003型福建舰，这是中国第一艘自主设计和建造的航母。
Officials have said work is already underway on a fourth ship.
官员们表示，第四艘船的工作已经在进行中。
But the government has not announced whether that ship will be nuclear or conventionally powered.
但政府尚未宣布这艘船将采用核动力还是常规动力。
How did the researchers arrive at their conclusion?
研究人员是如何得出他们的结论的？
Middlebury researchers were at first investigating a mountain site outside the city of Leshan in the southwest Chinese province of Sichuan.
明德学院的研究人员起初在考察中国西南部四川省乐山市郊外的一处山地遗址。
They had suspicions that China was building a reactor to produce radioactive materials such as plutonium or tritium for weapons.
他们怀疑中国正在建造一座反应堆，用于生产钚或氚等用于武器的放射性材料。
Instead, the researchers said they determined that China was building a test version of a reactor for a large warship.
相反，研究人员表示，他们认定中国正在建造一种用于大型战舰的反应堆测试版本。
A number of sources, including satellite images, project tenders, employee files, and environmental impact studies, led researchers to their conclusion.
多项来源，包括卫星图像、项目招标、员工档案和环境影响研究，使研究人员得出了结论。
The reactor is housed in a new structure built at the site known as Base 909, which is under the control of the Nuclear Power Institute of China.
该反应堆安置在一座新建建筑内，该建筑位于代号为909基地的场址，该场址由中国核动力研究设计院控制。
Documents show that China’s 701 Institute, which is responsible for aircraft carrier development, got reactor equipment meant “for installation on a large surface warship.”
文件显示，负责航母研发的中国701研究所获得了“用于安装在一艘大型水面战舰上”的反应堆设备。
The project’s “national defense designation” also helped lead to the conclusion the sizeable reactor is a test version for a next-generation aircraft carrier.
该项目的“国防 designation”也有助于得出这样一个结论：这个相当大的反应堆是下一代航空母舰的试验版本。
What does China say?
中国怎么说？
Chinese President Xi Jinping has tasked defense officials with building a “first-class” navy and becoming a naval power as part of his plan for the country.
中国国家主席习近平要求国防官员建设“一流”海军，成为海军强国，作为其国家计划的一部分。
China’s most recent white paper on national defense, dated 2019, said the Chinese navy was changing due to strategic requirements.
中国最近于2019年发布的国家国防白皮书指出，中国海军正因战略需求而发生变化。
The goal was to speed up “the transition of its tasks from defense on the near seas to protection missions on the far seas.”
目标是加快“其任务从近海防御向远海保护任务的转变”。
