The ice cap-made of solid carbon dioxide at temperatures as low as-143-'boils' every summer ( or, more correctly, 'sublimates' directly from solid form to gas), leaving huge pits in the Martian polar ice. 低至零下142度的气温下,由固体二氧化碳形成的冰冠每个夏天都会沸腾(或者更准确地说是从固体直接升华成气体),并在火星的极地冰里留下巨大的凹点。

These predict that if the level of carbon dioxide, methane and so on in the atmosphere continues to rise, then the Arctic Ocean will be free of floating summer ice by the end of the century. 假定大气层中二氧化碳及甲醇的排放量持续上升的话,模型预测到本世纪末北冰洋上的夏季浮冰将消失殆尽。
"The thought now is that carbon dioxide ice is so weak that it would flow away, like a glacier, even at very low temperatures," Zuber explains. 尤伯解释说:于冰太不稳定,甚至在温度很低的情况下,都会像冰川一样流走。
It showed that Mars 'polar ice caps are made of frozen water, not frozen carbon dioxide as previously thought. Like Antarctica, the Arctic is a land of ice and snow. 这表明火星极点冰盖是水冰,而不是先前认为的干冰。如同南极洲,北极是一个冰雪覆盖的大陆。
Black carbon in snow and ice is an important indicator of environment change and human activities. 储存在雪冰介质中的黑碳是了解古气候、古环境的变化以及人类活动历史的重要工具。
The clouds could also be depositing black carbon on the snow and ice, causing them to absorb, rather than reflect, solar radiation& and thus warm up. 这种云还能在雪和冰里沉积黑碳,导致它们吸收而不是反射辐射,从而让它们变暖。
A thaw occurs each spring in the Northern Hemisphere of Mars, as the warming climate causes solid carbon dioxide ice to sublimate directly to vapor. 火星北半球每到春天来临都会发生一次解冻,温暖的气候造成了固态的二氧化碳冰直接升华成气体。

The line is mainly used for washing, rilling sealing carbon dioxide drink, such as carbon dioxide water, cola, ice tea, aerated mineral water and so on. 该生产线主要用于矿泉水、纯净水、酒类等不含气饮料的冲洗、灌装、封口。
This article primarily discusses applications of carbon dioxide, dry ice and synthesis of chemical products, carbon dioxide supercritical carbon dioxide extraction technology. 主要论述了二氧化碳、干冰、二氧化碳合成化工产品以及二氧化碳的超临界萃取技术等方面的应用。
He is now studying the amounts of carbon dioxide and other gases in air bubbles in the ice, seeking to understand the ancient atmosphere. 他现在在研究冰的气泡中所含二氧化碳和其他气体的量,试图了解古代的大气状况。
At that time, dark sand on the interior of Martian sand dunes became more and more visible as the spring Sun melted the lighter carbon dioxide ice. 火星沙丘内部的暗沙,随着春日的阳光融化较薄的干冰而逐渐清晰可见。
Solid carbon dioxide ( dry ice) is used to cool meats prior to grinding and also to refrigerate meat and poultry during transit. 固态二氧化碳(干冰)用于在粉碎之前给肉类降温,还用于在运输过程中冷藏肉类和家禽。
Its surface temperature matches that of carbon dioxide ice, but might water ice lie underneath? 那里的地面温度符合使二氧化碳冰冻的温度,但在那之下是否还潜伏著水冰?
By use of carbon dioxide ice cleaning technology on the external surface of furnace tube by means of actual testing the furnace efficiency was raised 2.3%, the fuel was saved more than 980t per yea more than one million RMB economic benefit was created. 工业炉炉管外表面采用干冰清洗技术,经实际测试提高工业炉热效率2.3%,年节约燃料980t以上,创经济效益100多万元。
Black Carbon in Snow and Ice: A Review 雪冰中的黑碳记录研究的历史回顾
Abstract In order to study the long term performance reliability of solar powered carbon/ methanol ice maker, an investigation of thermal decomposition of methanol on alloy's surface under solar adsorption refrigeration condition has been carried out at Monash University. 本文介绍了在Monash大学开展的一项对固体吸附制冷机中的金属表面甲醇的热分解的研究,本研究目的是考察太阳能固体活性炭/甲醇制冰机运行性能的长久稳定性。
Different carbon source, nitrogen source and inorganic salts in medium affected the cell growth, the ice nucleation activity and the xanthan gum ratio. 培养基中不同的碳源、氮源和无机盐影响冰核细菌的生长、冰核蛋白的表达及黄原胶的产率。
If the mass transfer of solidified bed is improved, a two-bed adsorption ice maker ( each bed contains 48 kg activated carbon) could yield a daily 600 kg ice. 在块状活性炭吸附床的传质问题解决后,每个吸附床的吸附剂为48kg时,两床系统有望实现日制冰600kg。
A large number of carbon dioxide is the reason why there is close relationship between the Great Ice Age and organic evolution.

It is estimated that the amount of organic carbon in fired ice deposits on earth is twice as much as which included in the fossil energy, so fired ice is considered as backup energy in future. 据估计,地球上可燃冰矿藏中有机碳的含量是所有化石能源中有机碳含量的两倍,被认为是重要的后续能源。
Under the same pressure, with the increasing of the diameter of carbon nanotubes, the formation of ordered ice nanotubes show a more complex structure, and the phase transition temperature decreases. 在相同压强下,随着碳纳米管直径的增大,其形成的有序冰纳米管结构呈现更加复杂的结构,并且相变温度随管子直径的增大而降低,出现了与理论预测完全相反的结果。
