同样是这一天，站在南极点上的人也会看到太阳匆匆学过地平线，这便是长达六个月的极昼的开始。
On the same day, a person at the South Pole would also see the sun skim the horizon, beginning six months of uninterrupted daylight.
在北半球的秋分日那天，站在北极点上的人会看到太阳匆匆掠过地平线，这也预示着长达六个月的极夜的开始。
On the Northern Hemisphere's autumnal equinox day, a person at the North Pole would see the sun skimming across the horizon, signaling the start of six months of darkness.
这个平行线是一个有半径的圆，这个半径是小于a的，因为如果这个环越靠近北极点，它的半径实际上会越来越小。
So now, this parallel as a circle of radius, well, the radius is less than a because if your vertical is to the North Pole, it will be actually much smaller.
南纬60度线距南极点大约2000英里，它环绕地球，刚好错过南美洲的最南端，远在好望角和新西兰之南。
This line, running around the globe some 2, 000 miles from the South Pole itself, just misses the lower tip of South America, and is well below the Cape of Good Hope and New Zealand.
如果你以北极点为中心开始画圆，那么半径和半个子午线相等的圆周就是赤道，它包含的区域就是北半球。
If you start from that North Pole as centre, then the circle with radius equal to a half meridian is the equator, and the area included is the northern hemisphere.
然后构造了在预给极点情况下求主对角线和副对角线上向量值有理插值的矩阵算法。
In addition this paper constructs a matrix algorithm for computing bivariate diagonal vector valued rational interpolants with preassigned poles.
我们已经解释过了，行星X在围绕太阳南极点，上升到黄道的时候会沿著太阳的磁力线进行定位，在其轨道上朝著不幸的地球而来。
We have explained that Planet X positions itself along themagnetic flow lines of the Sun as it round the S. Pole of the Sunand rises to the Ecliptic, while heading toward the hapless Earthin its path.
最后根据焦点的“位迁”，在导出极点与极线式的基础上，阐述了各型镜面天线口径场的独有待色及其成因。
