Methods 477 cases (954 sides) of temporal CT images were retrospectively analyzed by statistics methods, and pneumatolysis types of processus mastoideus and petrous apex and the incidences of high jugular bulb in each type were calculated.

回顾性分析477例(954侧)颞骨CT片，统计乳突和岩尖的气化分型及各型颈静脉球高位的发生率，并对其作统计学分析。

Grain size refinement by dynamic recovery and recrystallization is thought to be responsible for the formation of foliated fault locks.

由动态恢复和动态重结晶控制的矿物颗粒的细粒化被认为是产生这些片理化断层岩的原因。

Rare elements and REE are mainly enriched in gray-black trachyte and less in other rocks. In addition, schistosity, pyritization, silicification and carbonation in gray-black trachyte are contributed to enrich rare element and REE. It is suggested that alkaline rocks in Hongyang area have the characteristics of subvocanics, and alkaline rocks in Hongyang and Miaoya areas all came from upper mantle and mixed with some substances of crust. Intrusion of alkaline rocks is related to the occurrence, development and evolvement of the deep rupture zone in the areas.

稀土、稀有元素主要富集于灰黑色粗面岩中，而在其他岩石类型中相对较少，同时岩石的片理化、黄铁矿化、硅化和碳酸盐化对稀土、稀有元素有进一步的富集作用；提出了本区的碱性岩组合具有次火山岩相的特征，讨论了本区碱性岩的成因，认为其与湖北庙垭地区的碱性岩可能均来自上地幔，并不同程度地混染了大陆壳的物质成分，其形成时代与断裂构造带的发生、发展和演化基本同步。

Have you ever been at sea in a dense fog, when it seemed as if a tangible white darkness shut you in , and the great ship, tense and anxious, groped her way toward the shore with plummet and sounding-line and you waited with beating heart for something to happen?

不知你是否有过这样的经历－在海上航行遇上了大雾，周围一片白，好像着实把你关在一个黑暗的地方，大船上的人又紧张又着急，一面用铅锤探测深浅，一面向岩边慢慢驶去，你的心也怦怦直跳，生怕出事。

The characteristic of the late Albian in Tethys Himalaya is deposition of black shale with glauconitic and phosphate beds, deposited during transgressive periods.

红层颜色醒目，岩性稳定，主要为紫红色-褐红色页片状泥岩和有孔虫泥质灰岩，其时代为晚白垩世Santonian期至Campanian期。

E. , the middle Devonian sedimentary event, which sedimented a suite of epicontinental -coasta1 paraf1ysch formation (the litholcgy was consisted of low fractoin feldspare sandstone and siltstone, and a layer of argilliferous limestone); secondly, the late Variscan magmatic-tectonic event , three biotite diorite batholiths ( previous K-Ar model isotope age was about 220～260Ma and our two -stage common lead isotope age was 260+ 70Ma) and a large number of fracture-controlled quartz diorite veins intrude, and a series of NS distributed tightly complex folds and fractures were developed; thirdly, the late Paleozoic very 1ow grade metamorphism- deformation event, the chlorite-illite crystallinity indices (Δ°2θ) XRD measurements were about 0.25～0.29, which was correlated to the lower part of the anchimetamorphism, and the extremely dense schists were developed throughout the district outcrops

相当于近变质带的下部，并形成切穿矿区几乎所有主要地质体的窃集片理，这与有限相系浅变质碎屑岩的基本宏观地质特征相吻合

This vast tweed of feathery grasses, red bearberries, and green crowberries attracts grazing reindeer, berrypicking bears, and curlews that swoop in by the thousands to strip the bushes of their fruit.

这片辽阔的粗花呢似的柔美草地、红色熊莓和绿色岩高兰吸引着放牧的训鹿、采摘浆果的熊，以及成千上万的采食矮树丛上水果的杓鹬。

In the river valley region,discal phenomena of drilling cores and laminated exfoliation of surrounding rock in the exploration tunnels are obvious.

拉西瓦水电工程坝址区为高山峡谷地貌，受地质构造应力、自重、地表剥蚀和河流侵蚀卸荷等多因素影响而赋存有高地应力，河谷区钻孔岩芯饼化与探洞片状剥落现象明显。

The samples on the right side of the table look like layered rocks. are they foliated fault rocks?

在桌子右边的岩石看起来像层状岩石，它们就是片理化的断层岩吧？

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。
