: 摘要:
: EM Drive Fuel-free engine could take a spacecraft to Mars in 10 weeks.
: Creates thrust by bouncing microwaves in chamber, using solar power.
: Nasa has conducted more tests using an improved experimental process.
: Test designed to remove errors from earlier study but still produced thrust.
: Scientists still aren't sure how this happens as it defies the laws of physics.

搭载EM drive 无燃料引擎的火箭到火星需十礼拜 借由太阳光所生产生的微波增幅动力
NASA 现在已经建立数个实验引擎 试图改善该引擎早期测试的诸多问题
科学家仍不能确定这到底如何发生好像是它打破了物理定律
全文:
: An 'impossible' fuel-free engine, which could take a humans to Mars in just
: 10 weeks, is still defying science after another batch of tests by Nasa
: suggested the thruster does work.
: The so-called EM Drive creates thrust by bouncing microwaves around in an
: enclosed chamber, and uses only solar power.
: When the concept was first proposed, it was considered implausible because it
: went against the laws of physics - and subsequent tests of the engine have
: shown that the idea could revolutionise space travel.
这引擎可能会改写太空旅程的进展
: Now Nasa has provided the first update on the test in months, and it seems to
: suggest that the futuristic engine does, in fact, work.
: Scientists, however, still don't know why.
NASA将会提供第一段的测试数据在数个月内
但科学家们仍不知道其原因
: The update was given by Paul March, one of the top engineers working the EM
: Drive thruster at the Eagleworks Laboratory at the Johnson Space Center in
: Texas.
Paul 是这方面顶尖的科学家 在德州的强纳森太空中心
: He said Nasa has managed to remove some of the errors from earlier tests -
: but still found signals of unexplained thrust.
: Among the criticisms of previous experiments were that the tests were not
: carried out in a vacuum, thereby mirroring the conditions in space.
: But the latest Nasa test appears to have addressed these concerns.
: March's announcement is the first direct announcement in months, with the
: space agency largely remaining silent about any developments on the
: controversial project.
他说仍有数个问题存于现在的早期测试 但发现有个不知从何而来的推力
尽管有许多批评包括早期测试不在真空中
因此更不接近于太空的条件
但NASA 的数据显示 太空中的真空条件更有利于该争议性计画
: March posted on the Nasa Spaceflight forum in reply to an unpublished paper
: that claims the unaccounted thrust is generated by something known as the
: Lorentz force.
: The Lorentz force is the force that is exerted by a magnetic field on a
: moving electric charge.
: But March says his tests prove this is not true.
: 'I will tell you that we first built and installed a second generation,
: closed face magnetic damper that reduced the stray magnetic fields in the
: vacuum chamber by at least an order of magnitude and any Lorentz force
: interactions it could produce,' he said
: 'And yet the anomalous thrust signals remain.'
: March also says that in the latest developments, thermal expansion of the
: thruster is taken into account to reduce all possible sources of error.
Paul March 在 NASA 太空论坛上回应关于一篇论文 该论文宣称 那种未知推力有点像
劳伦兹力
劳伦兹力 来自于 运动电荷在磁场中所产生的一种推力
但March 确认为他的测试显示那论文是错的
他说"我告诉你们 我认为我们建造的是一种第二代的引擎 其磁阻接近劳伦兹力并
减少磁场的迷散在真空中 生产至少一股以上的磁场与劳伦兹力的的交互作用所能
产生的作用力
但我们的不寻常的推力是可维持"
他也提到 最新的发展 我们仍试图在热膨胀理论上找出涡轮上问题
并减少其推力来源错误可能

简单翻一下 我不学物理的 有些不确定有没有翻错
只是测试好吗= =
