There are two kind of zicons in amphibolite from the Haiyangsuo area,eastern Shandong Province:(1)Xenocrysts,they give 207Pb/208Pb age of 2149Ma,which suggests an early proterozoic basement in this area;(2)Magmatic euhedral zircons,they give an upper intercept age of 1784±11Ma and lower intercept age of 448±13Ma.

中文摘要：胶东海阳所胶南群斜长角闪岩中的锆石有2类：（1）捕掳晶锆石，它给出2149Ma 的207Pb/206Pb 年龄，证明该区存在有早元古基底；（2）岩浆结晶锆石，它的不一致线上下交点年龄分别为1784±11Ma和448±13Ma。

The hypo-volcanic crytoexplosion Breccia rock body and the felstone in the east-western shear zone are the important symbol of the exploration.

东西向脆－韧性剪切带内次火山隐爆角砾岩体、霏细岩脉的存在是区内重要的找矿标志。

Most of the smaller hornblendite bodies contain about 5-10 percent magnetite , with only local sporadic enrichment

在小的角闪岩体中，磁铁矿可占510%，仅有局部的散染状富集。

It is confirmed that the correlation exists between head form and the angle of temporal petrous, as well as the height of internal occipital protuberance.

头型与颜骨岩矢角及枕内粗隆的解剖学特徵存在一定相关性，是影响颅脑CT扫描影像品质的因素之一。

The microfracturing process of Jinping marble specimen in Sichuan province under uniaxial compression is recorded by using the testing scheme. Quantitatively investigated the propagation and coalescent of cracks at meso-scale with digital technology, the basic geometric information of rock microcracks such as area, angle, length, width, perimeter, are obtained from binary images after segmentation. The failure mechanism of specimen under uniaxial compression with the quantitative information is studied from macro/micro scopic perspective. The result shows that during the damage of the specimen the distribution of microcracks in the whole specimen are still subjected to exponential distribution with some microcracks concentrated in certain regions.

应用于四川锦屏大理岩预制裂纹试样中进行单轴压缩破坏全程的数字化试验，对微裂纹的萌生、生长及贯通过程进行数字化定量分析，得到试样在受荷过程中微裂纹的面积、方位角、长度、宽度和周长基本几何数据，从宏细观角度描述了岩石试样单轴压缩过程中的破坏机制，并分析得出试样单轴受压破坏过程中虽然微裂纹在某些区域集中，但在整个试样中微裂纹的统计分布依然是服从某一指数分布的这一结论。

To explore the microdissection of the cerebellopontine angle as well as to study the advantage and disadvantage of the retrosigmoid approach and the retrosigmoid suprameatal approach, the relationship among the facial nerves, inter-medium nerves, anterior inferior cerebellar artery and petrosal vein were studied, and two approaches particularly also were explored from fifteen dry skulls and ten wet skulls, along the approach of RSA and RSSMA.

本研究旨在了解桥小脑角的显微解剖；探讨枕下乙状窦后入路及乙状窦后-内耳道上入路的优缺点。本实验采用15例(30侧)干标本和10例(20侧)湿标本，按照枕下乙状窦后入路和乙状窦后-内耳道上入路的所涉及的解剖区域，解剖观测面神经、中间神经、小脑前下动脉及岩静脉等诸多结构，并对神经外科手术乙状窦后入路及乙状窦后。

During retrograde metamorphism with amphibolite facies, a little Zr released from rutile, which was transformed into titanite, can be supplied to zircon overgrowth. Therefore, SHRIMP U-Pb ages of retrograde overgrowth zircon should represent retrograde amphibolite facies age.

在退变质过程中，金红石退变为榍石的反应可释放少量Zr，因此退变质增生锆石U-Pb年龄应指示角闪岩相退变质时代。

The Yiarmand gold deposit occurs in hydrothermally eruptive breccia of the 2nd Member of Lower Carboniferous Dahalajunshan Formation and its underlying arsenopyritized and pyritized tuffaceous clastic rocks,and the ore forming process can be divided into hydrothermally eruptive and sedimentary stage and metasomatic stage.

伊尔曼德金矿床赋存于下石炭统大哈拉军山组第二岩性段硅化热液喷发角砾岩及其下伏上泥盆统吐呼拉苏组毒砂黄铁矿化凝灰质碎屑岩中，成矿作用可分为热液喷发沉积期和热液交代蚀变成矿期。

Squatting, lying, and milling aimlessly about the lower level were a dozen of so large lizard-like beasts that looked like the product of some mad geneticist's cross of Tatooine krayt dragons wit h Haruun Kal ankkoxen : four meters tall at the shoulder, long crooked legs that ended in five-clawed feet clearly designed for scaling rocky cliffs, ten meters of powerful tail ridged with spines and tipped with a horn-bladed mace, a flexible neck leading up to an armor-plated head that sported an impressive cowl of spines of its own—they looked fearsome enough that Obi-Wan might have thought them some sort of dangerous wild predators or vi cious watchbeasts, were it not for the docile way they tolerated the team of Utai wranglers who walked among them, hosing them down, scraping muck from their scales, and letting them take bundles of greens from their hands.

在下层那儿，蹲着的，躺着的，或是在漫无目的地殴斗的，是整整一打类似蜥蜴的巨型野兽，它们看上去就像是某个科学狂人将塔图因的克雷特巨龙和哈伦·卡尔的安科森兽糅合在一起的成品：肩高四米，长而弯曲的腿的末梢长着五根用于攀登岩壁的爪子，十米长的强壮尾部上扎满了尖刺，末端是一个尖角满布的骨槌，柔韧的颈部支撑着一个布满铠甲的脑袋，脑袋上又炫耀着一簇可怕的尖刺——它们的长相实在太恐怖了，使得欧比旺不禁觉得这些家伙不是危险的野生掠食者，就是冷血的守卫神兽，可恰恰相反，它们在那些尤泰牧人面前却表现得十分乖巧温顺，任由他们从中穿行，往它们身上浇水降温，从它们的鳞片上刮去污物，以及将一捆捆青草递到它们嘴边。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
