On Earth, breccia is a jumble of broken rocks cemented together by fine-grained material that is found around volcanoes and impact craters.

在地球上，角砾岩是火山周围和遍布陨石坑中由破碎岩石胶混合粘结在一起的细粒物质。

In console land, they're already being treated to a new Battlefield game, Subtitled Bad Company, it's debut of the next-gen "Frostbite" engine. Aside from producing staggering draw distance that lets you pick off targets miles away, it's imbued with some serious deformation technology. Buildings can be blown apart, bridges burst and craters carved.

官方已经证实正在制作一个新的战地游戏，叫叛逆连队或者最差拍档，它的首次亮相在展示寒霜引擎，除了更高的视距，更强的画面，他还包含很多的物理特效，例如建筑物被炮弹吹飞，桥梁被爆炸炸出坑洼。

Like Callisto, the craters lack the high relief features seen on the Moon and Mercury.

像木卫四一样，这些陨石坑缺少在月球和水星上可看到的高度起伏的表面。

The material surface has a characteristic appearance composed of numerous small craters.

电火花加工后的材料表面具有的特点是它由许多小弹坑组成。

However, because of lacking high efficiency and high precision for the measurement of craters on the conical surface rock, the traditional single row drilling experiment is carried out on planar rock.

由于缺乏对锥面岩石破碎坑的有效的、高精度的测量手段，所以传统的单齿圈试验都是针对平面岩样进行的。

Pictured above, Telesto's unusually smooth surface was found to show some large craters and boulders, but not the high density of craters found on nearby Tethys or most other Saturnian moons.

在上面影像中，土卫十三不寻常的平滑表面上有一些较大型的陨石坑和圆形团块，但没有像邻近的土卫三或其他的土星卫星一样上面有密密麻麻的陨石坑。

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.

本项目立足于从火山岩属性和深源捕掳体反演源区成分与结构两个途径，利用火山岩综合研究成果对地幔源区进行了初步反演，提出源区经受过强烈钾质交代的观点；对重点工作区TM图像进行了初步解译，新发现若干了火山口，并对其中三个火山口作了实地查验，为进一步全面深入开展该区的火山地质学及相关科学问题打下了良好基础，认为托云盆地是一个火山群，而不是一个单一的火山构造盆地；系统测制了火山岩剖面，新采集了一批重要的火山岩和深源岩石捕虏体样品，为下一步工作打下基础，特别是采集到了直径打20cm的幔源橄榄岩包体，可用于各种测试，将可以结束西部造山带没有地幔岩化学分析结果的历史；对康西瓦玄武岩进行了测年分析，取得了我国目前最年轻的锆石U-Pb SHRIMP年龄，对青藏高原挽近地质时期的隆升提供了年代学约束；对帕米尔东缘塔什库尔干碱性岩体的动力学意义进行了探讨，提出青藏高原西部构造结的形成与岩浆活动有关的观点。

We find that 'secondaries'(craters formed by material ejected喷射 from large primary impact craters) comprise about 95 per cent of the small craters (diameters less than 1 km) on Europa.

我们发现，secondaris（火山口由从主要火山口抛出的材料形成）由欧罗巴上的将近95%的小火山构成。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
