您要查找的是不是：
- An inexplicable new broad region of auroral light has been photographed at Saturn's polar cap. 一種無(wú)法解釋的大范圍新型極光出現在土星的極蓋地區，被攝像機拍攝下來(lái)。
- And some may exist in the southern polar cap -- but not much. 還有些存在于南部極地冰冠中一但不會(huì )太多。
- 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. 在上面的影像中還可以看到火星的北極冰帽，色彩深淺不一的土壤，云層，以及在早期相片中的出現的全球性沙塵暴。
- 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極地冰冠。
- So to maintain the topography of the south polar cap,there has to be water ice in there stiffening it up. 所以要想維持南部冰冠的地形，就必須有冰水使其變得堅固。
- Melt-Proof The south polar cap is mostly frozen carbon dioxide, which shrinks during the summer but never disappears. 南極蓋上有很多凍結的碳氧化合物,這些東西在夏天會(huì )收縮,但從來(lái)沒(méi)有消失過(guò)。
- The disappearance of polar cap will greatly affect polar bears and other halobios. 冰帽的融化會(huì )給北極熊等海洋生物造成嚴峻后果。
- Earth will become a desert planet, with at most a shrunken polar cap and only traces of precious liquid. 地球將會(huì )變成沙漠般的行星，最多還有個(gè)縮小的極帽和從前液體留下的遺跡。
- Amateur astronomers looking through backyard telescopes have reported in recent days great views of Mars's south polar cap. 最近,業(yè)余天文愛(ài)好者已能用自家院里的望遠鏡觀(guān)測火星南極極冠的壯美景象。
- 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. 一般說(shuō)來(lái),極蓋區外電場(chǎng)分布的位相與極蓋區邊界的驅動(dòng)勢不同,一、二區場(chǎng)向電流的位相與驅動(dòng)勢也有差異。 這些現象都是場(chǎng)向電流與電導率共同影響的結果。
- 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. 美國宇航局的科學(xué)家于9月20日表示，火星上的氣候正顯示出逐漸變暖的趨勢，同時(shí)最近拍攝到的火星圖像也顯示出火星上存在地震活動(dòng)的首個(gè)證據。
- The two systems of government are polar opposites. 這兩種政體正好相反。
- I groped for the light switch in the dark room. 我在黑暗的房間里摸索著(zhù)找電燈開(kāi)關(guān)。
- Driving electric field at the polar cap boundary 極蓋區邊界驅動(dòng)電場(chǎng)
- Because the crystalline cellular structure holds a higher vibration, global warming will continue and in time melt both polar caps of all ice. 因為水晶細胞結構持有一個(gè)更高的振動(dòng)，全球變暖將繼續，并在不久溶化南北極的全部冰帽。
- 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。更確切的說(shuō)，地表和地下的冰（尤其在冰帽里）以及大氣中的水汽。
- The portrait shows fine effects of light and shade. 這幅肖像畫(huà)的濃淡色調表現得很好。
- Yet another tipping point could come as ice sheets shrink and the polar caps start absorbing rather than reflecting energy from the sun. 然而另一個(gè)引爆點(diǎn)的出現，則可能是冰原的縮減，極冠轉反射太陽(yáng)的能量為吸收。
- A red light is usually a signal of danger. 紅燈通常是危險的信號。
- Now I begin to see light on their good intentions. 現在我對他們的良好動(dòng)機開(kāi)始有所領(lǐng)會(huì )了。
