南极

The Geographic South Pole is where Earth's axis of rotation intersects its surface.

地理上的南极点是地球自转轴线与表面的交差处。

Astrophysicists working with groundbased detectors at South Pole and balloon-borne instruments are closing in on such structures,and may report their findings soon.

天体物理学家使用在南极的陆基探测仪和气球搭载的仪器进一步观察这种结构，很快就会报告他们的发现。

Astrophysicists working with groundbased detectors at the South Pole and balloon-borne instruments are closing in on such structures,and may report their findings soon.

天体物理学家使用南极路基探测器及球载仪器观察这些结构，并很快将报道他们的发现结果。

Similar low ozone amounts over the Antarctic continent have been observed by a TOMS instrument on a National Oceanic and Atmospheric Administration satellite, as well as by balloon-borne instruments flown from the South Pole and ground-based spectrometers.

另外，位于美国国家海洋气候管理局的卫星上的'TOMS'仪器，以及从南极放飞的由气球携带的仪器还有陆上的分光计，都已得到相似的数据表明，南极洲臭氧含量过低。

Around a bar magnet , for example, the lines of force point from the north pole to the south.

例如，在磁铁棒周围的磁力线从北极指向南极。

Both the sun's magnetic field and the Earth's magnetic field can be oriented northward or southward (Earth's magnetic field is often described as a giant bar magnet in space).

太阳和地球的磁场都可以定向为南极和北极（地球的磁场通常被描述为一个在空间中的巨大条形磁铁）。

Around a bar magnet , for example, the l s of force point from the north pole to the south.

例如，在磁铁棒周围的磁力线从北极指向南极。

At the South Pole the winter average is about 73 degrees below zero.

而在另一端的南极，冬天的平均气温则在零下73度左右。

The giant Pacific stretches 9300 miles from the Arctic Circle at Bering Strait to the South Polar zone.

巨大的太平洋延伸九千三百英里从北极圈白令海峡到南极区。

The giant Pacific stretches 9,300 miles from the Arctic Circle at Bering Strait to the South Polar zone.

浩瀚的太平洋从北极圈的白令海峡到南极地带绵延9300英里。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
