您要查找的是不是：
- And some may exist in the southern polar cap -- but not much. 还有些存在于南部极地冰冠中一但不会太多。
- Zuber and her colleagues also analyzed Mars's much larger northern polar cap. 尤伯和她的同事也分析了火星上要大得多的北部极地冰冠。
- Because the crystalline cellular structure holds a higher vibration, global warming will continue and in time melt both polar caps of all ice. 因为水晶细胞结构持有一个更高的振动，全球变暖将继续，并在不久溶化南北极的全部冰帽。
- There is water on Mars. More specifically, there is ice in and on the ground (especially at the polar caps) and water vapor in the atmosphere. 火星上有水。更确切的说，地表和地下的冰（尤其在冰帽里）以及大气中的水汽。
- Yet another tipping point could come as ice sheets shrink and the polar caps start absorbing rather than reflecting energy from the sun. 然而另一个引爆点的出现，则可能是冰原的缩减，极冠转反射太阳的能量为吸收。
- So to maintain the topography of the south polar cap,there has to be water ice in there stiffening it up. 所以要想维持南部冰冠的地形，就必须有冰水使其变得坚固。
- Melt-Proof The south polar cap is mostly frozen carbon dioxide, which shrinks during the summer but never disappears. 南极盖上有很多冻结的碳氧化合物,这些东西在夏天会收缩,但从来没有消失过。
- Observations from Earth and the Hubble Space Telescope show that Pluto has a highly reflective surface with distinct markings that indicate the presence of expansive polar caps. 从地球与哈伯太空望远镜可以看到冥王星表面的反射性很强，还有很显著的斑纹，显示有广阔的极冠。
- The disappearance of polar cap will greatly affect polar bears and other halobios. 冰帽的融化会给北极熊等海洋生物造成严峻后果。
- An inexplicable new broad region of auroral light has been photographed at Saturn's polar cap. 一种无法解释的大范围新型极光出现在土星的极盖地区，被摄像机拍摄下来。
- Earth will become a desert planet, with at most a shrunken polar cap and only traces of precious liquid. 地球将会变成沙漠般的行星，最多还有个缩小的极帽和从前液体留下的遗迹。
- Amateur astronomers looking through backyard telescopes have reported in recent days great views of Mars's south polar cap. 最近,业余天文爱好者已能用自家院里的望远镜观测火星南极极冠的壮美景象。
- Visible also in the above images are the north polar cap of Mars, dark and light soil, clouds, and, in the early images, a global dust storm. 在上面的影像中还可以看到火星的北极冰帽，色彩深浅不一的土壤，云层，以及在早期相片中的出现的全球性沙尘暴。
- Generally the phase, of the potential distribution outside the polar cap is different from that of the driving potential at the polar cap, and so are the phases of the region 1 and 2 field-aligned currents. 一般说来,极盖区外电场分布的位相与极盖区边界的驱动势不同,一、二区场向电流的位相与驱动势也有差异。 这些现象都是场向电流与电导率共同影响的结果。
- The two systems of government are polar opposites. 这两种政体正好相反。
- Malin said images of Mars' southern polar cap showed that scarps formed there are retreating at "a prodigious rate" of about 10 feet per Mars year.Mars years are nearly twice as long as Earth years. 美国宇航局的科学家于9月20日表示，火星上的气候正显示出逐渐变暖的趋势，同时最近拍摄到的火星图像也显示出火星上存在地震活动的首个证据。
- Polarized caps will be gone, oceans will rise, entire countries will disappear. Life will change in ways you can't even imagine. 极地冰盖将不复存在，海洋会上升，整个国家都会消失。生活将以妳不能想象的方式变化。
- Most insect do not live in polar region. 大多数的昆虫不在极地地区生存。
- Who is the boy in the official school cap? 那个戴校帽的男孩是谁？
- Driving electric field at the polar cap boundary 极盖区边界驱动电场
