Data of major andminor elements in magnetite, cassiterite, galena and sphalerite from oredeposits within this ore belt suggest that these ore deposits are of skarn,hydrothermal, porphyry and greisen types related to Yanshanian magmaticactivity and that iron in ores came from regional Permian marine interme-diate-basic volcanic rocks whereas partial lead and zinc from Permian geo-synclinic sediments.

矿带中各矿床的磁铁矿、锡石、方铅矿、闪锌矿的主元素和微量元素数据表明，这些矿床是属与燕山期岩浆活动有关的矽卡岩型、热液型、斑岩型和云英岩型矿床；其成矿金属组分中的铁来源于区域晚古生代海相中-基性火山岩，部分铅锌来源于区域二叠纪地槽沉积物。

We need to select multiple layers, you can by using the Select tool from the selected file, functioningas come up with a select gridlines, and then hold down the ALT key "", when the cursor turns into a corner with a small big ""-+"" numbers (this means that by selecting a zone or pixels), in the first box inside pull-out the second box and hold down the Shift key "", when the cursor changes to a corner with a small big ""++"" letter, and then in the second box inside out the third selection box so that you can use both on a rotational basis, multi-tier choice.

我们必给众层拔取时，可以不后用拔取东西选定文件洋的地区，拉制不入一个拔取虚框；然后按住"Alt"键，当光标酿成一个右下角带一小"-"的不小"＋"号时(这表现加少被拔取的地区或像素)，在第一个框的本质拉不入第二个框；而后按住"Shift"键，当光标变为一个右下角带一小"＋"的不小"＋"号时，再在第二个框的本质拉不入第三个拔取框，这样二者轮番搁置，即可进动众层拔取了。

Dr Gros and his colleagues are examining the second part of this process because it is after this stage that infected blood cells can become trapped in small blood vessels in the brain, causing cerebral malaria and, potentially, death.

Gros博士和他的同事们正在研究这个过程的第二部分。因为正是是经过这个阶段，被感染的血细胞可能滞留在大脑的小血管中，从而引起脑型疟疾，并可能最终导致死亡。

The microstructure of an uvarovite sample was analyzed using SEM methods. Tiny quartz and chromite inclusions, calcite filling in microfractures and grossularite that forms a solid solution with uvarovite were discovered in the sample. This demonstrates that the uvarovite of eastern Tibet is of skarn origin. The spectral characteristics of the uvarovite were investigated using UV-VIS absorption spectrometry.

采用扫描电镜观察钙铬榴石样品的显微结构并进行能谱分析，结果表明其内部含有颗粒很小的铬铁矿和石英包裹体，以及裂隙中充填的方解石和与钙铬榴石为类质同象连续关系的钙铝榴石，从而为该钙铬榴石的夕卡岩成因和产状提供了佐证。

The turn speed is measured with an external hall probe and the oscilloscope, this give me a precise measurement, for instance when I insert an 6mm aluminum sheet I can see on the scope the pulse periode increased quickly, this shows that the speed of the motor drops also quickly due to the eddy currents induced in the aluminum sheet.....

转速度是衡量一个外部霍尔探头和示波器，这给我一个精确的测量，例如，当我插入一个6mm的铝板，我可以看到的范围脉搏 periode迅速上升，这表明速度电机也下降很快，由于涡电流致该铝板。。。。。。

Hence, we first analyzed and studied the kinematics and dynamics of PDC bit, and that are utilized to analyzed how to hame cutters by PDC bit whirlpool. Onthe based of this, we do the cutting experiments. With the test, we not only think over the influence to force actting on cutters in rock nature, drilling parameter, cuttersdensity distributed, and also wear state of cutters and PDC bit appearance. Because the PDC bit's cutters are repeaded by polycrystalline-diamand and tungsten carbide, the specific property of PDC wear are not alike that of polycrystalline-diamand and not alike tungsten carbide.

因此，本文首先分析研究了PDC钻头的运动学和动力学，并利用分析的结果对PDC钻头的涡动是如何损坏切削齿的进行了探讨；在此基础上，进行了PDC钻头切削齿的受力实验，在受力实验研究中，不仅考虑了岩性、钻进参数、布齿密度等对切削齿受力的影响，而且考虑了切削齿不同的磨损状态、钻头的冠部形状对切削齿受力的影响；PDC钻头的切削齿是由聚晶金刚石层和碳化钨底层复合而成的，它的磨损特点既不同于金刚石的磨损又不同于碳化钨的磨损，因此，在分析了复合片磨损机理的基础上，进行了PDC钻头切削齿的磨损实验。

"This is great news for stroke survivors because results clearly demonstrate that long-term stroke damage is not immutable and that with exercise it's never too late for the brain and body to recover," says Daniel Hanley, MD, professor of neurology at the Johns Hopkins University School of Medicine.

"这是好消息，因为中风幸存者的结果清楚地表明，长期中风损害不是一成不变的，在行使它永远不会太晚的大脑和身体恢复，说："丹尼尔汉，医学博士，教授，神经病学上约翰霍普金斯大学医学院。

I felt we both knew that this story was risky and that he wanted to take the story on, probably for the creative challenge and, perhaps,(though he didn't say so) for the gasping euphoria when you get into unknown but hard-driving imaginative projects.

尽管李安没有说自己在转化这个悲伤。可能他也是为了进入一个艰难的拍摄计划而忘却逝父的悲伤从而从工作中吸取快乐？
