查询词典 ice-skate

It is found that water velocity vertical distribution under ice-cover is influenced mainly by the relative size of channel roughness and ice-cover roughness, less by the water depth and not sensitive to the variation of Reynold number as well, which is relatively uniform in the flow core and deviates from the logarithmic law.

结果表明：冰盖下水流流速垂向分布主要受床面与冰盖粗糙度的相对大小影响，受水深影响较小，对雷诺数变化并不敏感；在流动核心部分分布较为均匀，并不遵循对数分布规律。

Finaly, the reliability of static ice force for different reccurrence periods is calculated by taking Schwarz formula as formula of calculating static ice force and results are simulated by Monte Carlo important sampling method.

最后，以Schwarz公式为静冰力计算公式，结合得到的冰厚和冰强度的概率分布，采用映射变换法进行不同重现期静冰力的可靠度分析计算，并用蒙特卡罗重点抽样法进行模拟。

It then used the rasp on the scoop at the end of the arm to make 50 scrapes in the ice and then heaped the scrapings into little piles each with about two to four teaspoonfuls of ice.

然后，"凤凰"号用机械手末端铲子上的粗锉刀在冰上刮擦了50下，接着将刮下的冰屑堆成小堆，每堆约有冰屑2至4茶匙。

Polar Bear on Sea Ice、A polar bear leaps off of sea ice near Devon Island in the Canadian Arctic.

加拿大得文岛附近，一直北极熊纵身越向另一块海冰

They can not go deep into to the place that the north holds more in general , the sea dog also has no way to break ice but producing , not having food , polar bear at ease is not able to go to take risks including their mainest prey because of there floating ice has been very thick.

它们一般不会深入到更北端的地方，因为那里的浮冰太厚了，连它们的最主要猎物——海豹也无法破冰而出，没有食物，北极熊自然不会去冒险。

Patterns in Nature: Snow and Ice Cracks spider through Arctic sea ice in Franz Josef Land, Russia Photograph by Carsten Peter

意译：冰雪在自然界的模式。像蜘蛛般的并裂缝穿过北极圈的冰海在弗朗茨约瑟夫陆地，俄罗斯。

The micro crack behavior in ice is the key factor for describing and explaining ice-induced self-excited vibration.

冰内部的微裂纹行为是解释与描述冰致自激振动的关键要素。

The paper has given an overview on domestic and abroad research status of the climatic changes during The Little Ice Age, mainly depending on the different proxies such as ice cores, tree-ring, lake sediment, documentary and desert semimetal strata.

并重点从冰芯、树轮、湖泊沉积、历史文献和沙漠地层等方面综述了近年来国内外对小冰期气候变化的研究现状。

看着如此美丽动人的冰冰，男人都不是柳下惠，偶尔想占点廉价也可以理解，谁叫人家那么有杀伤力。

The operating principle and component of the shadowgraph experimental station were introduced. The clear shadowgraph of target was gained after construction. Using this technique, the calculative method of DT ice thickness and the surface roughness analytic method of target were realized. Through design simulative experiment, the shadowgraph of DT ice was got.

主要介绍了背光成像实验样机的组成及工作原理，讨论了各光学部件的选择，在原理型样机建成后，获得了玻璃微球靶高质量的背光图像，通过对背光影像的光路图分析与测量（测量精度达到1μm），掌握了靶球DT冰层厚度的计算方法；初步建立了靶球二维内外表面粗糙度分析方法；通过设计模拟实验，获得了冰层在微球靶丸内均匀分布后清晰的背光影像。
