英汉例句

• with the magnetic field turned on, the iron layers both magnetize, say, in the spin-up direction, so all of the spin-down electrons move through the entire sample without scattering.

• with the more precise data and the sdo’s ability to see the whole sun at once, scientists anticipate that they’ll be able to solve some longstanding questions about how the sun’s magnetic field works.

  因为有更精确的数据，还有太阳动态观测台一次能够观察整个太阳的能力，科学家预计能够解决关于太阳磁场如何运作的一些长期存在的问题。

• this creates a secondary magnetic field around the cans that is repelled by the magnetic field of the rotor, literally ejecting the aluminium cans from the other waste materials.

  这样，被转子磁场隔开的铝罐周围就会产生一个二级磁场，实际上也就能将铝罐与其它废料隔离开来。

• in particular, every electron has its own magnetic field aligned with the axis of its spin.

  特别是每个电子自身都会产生与其自转轴相一致的磁场。

• electrons flowing through the chip would 「see」 a magnetic field that flips from one direction to the opposite every few hundred nanometres (billionths of a metre).

  穿过芯片的电子可以「识别」某一磁场，该磁场每隔几百纳米（十亿分之一米）就变换一次方向。

• the satellite is designed to study the sun「s magnetic field to help scientists better understand how its energy propagates through different layers of the sun」s atmosphere.

  这颗卫星设计的目的是研究太阳磁场以帮助科学家更好地理解它的能量怎样传播穿过太阳大气的不同层。

• lohmann speculates that hatchling turtles may imprint on the magnetic field of their home beach and, if so, such a phenomenon could be the basis of strategies for species preservation.

  罗曼推测，人工孵化的海龟也许会留下它们家乡海滩磁场的烙印，如果是这样，这种现象可能会成为物种保护的策略基础。

  这种手段在一小块头骨上形成一个磁场，既而在大脑中产生微弱的感应电流。

• such machines are known as 「asynchronous」 motors, because the rotor’s magnetic field never catches up with the stator’s field.

  因为其中转子的磁场与定子的磁场不同步，所以这种机器被称为「非同步」发动机。

• that reverses the polarity of the atom’s magnetic field and ejects it from the trap.

  这就会改变原子原来的极性和磁场，原子就会从磁阱中弹出去。

• since a magnetic field changes the resistance of ordinary metals by only a fraction of a percent, they dubbed this phenomenon 」giant magnetoresistance," or gmr.

  由于磁场变化对普通金属只会造成远远不到百份之一的电阻变化，这种现象被称为「巨磁电阻」或巨磁阻gmr。
