The growth and nucleation rates of〓 cleavage face of YbYAB crystal are all very fast, because so many growth steps and growth centers were formed within only 2～3 second at the temperature near the saturate point. No spiral growth steps can be found, so growth mechanism is twodimensional nucleation. When the flux temperature increases for only 0.5℃ above the saturate point, the spiral melting holes are formed. The transformation from growth morphologies to melting morphologies is very sensitive to the temperature. When the temperature increases another 1℃, the spiral melting holes transform into two-dimensional nucleation melting holes.

YbYAB的〓解理面的生长及成核速度都非常快，在比饱和点低0.5～1℃的温度下，当生长2～3秒钟时，可以看到许多生长中心与生长台阶的形成，在较宽的台阶上还可以看到二维核的形成，没有看到螺旋中心，说明生长机理是二维成核生长；当温度比饱和点高0.5℃时，在〓解理面上形成螺旋状熔坑，这表明形貌由生长到熔化的转变与温度的关系是非常敏感的；当温度比饱和点高1.5℃时，螺旋状熔坑转变为二维成核状熔坑。

"Families in the Gulf Coast see that as they wait to rebuild their lives," he said.

"当海湾附近的家庭无助地等待着重新恢复生活时，政府的态度让他们认清了现实；当失业的美国人期待着重新开始工作时，政府的态度让他们认清了现实；当我们的士兵们在伊拉克正努力重建一个国家时，政府的态度让他们认清了现实。"

While therefore being to meet a difficulty, you will not shrink back and you will brave to overcome;While meeting failure, you will not give up, you would heavy head again come;While meeting distress, you will not complain and you will presume to win.

因此，当遇到困难时，你不会退缩，你会勇于克服；当遇到失败时，你不会放弃，你会重头再来；当遇到苦难时，你不会抱怨，你会敢于战胜。

With a dip angle between 15° and 30°, the uplift of an obducted plate during continental collision is much higher, and able to form a high mountain. The uplift is greatest with a dip angle of 15°; whereas with a dip angle between 30° and 45°, the subduction depth of a plate is much deeper, and able to form a deep basin. The subduction depth is greatest with a dip angle of 45°. When the dip angle is equal to or greater than 75°, subduction and obduction movements between two continents become undistinguishable.

当断裂带倾角在15~30°时，两个大陆板块碰撞导致的仰冲板块一侧隆升高度相对更大，利于形成高大的山脉，其中以15°倾角对应的仰冲板块一侧隆升最高；当断裂带倾角在30~45°时，两个大陆板块碰撞导致的俯冲板块的俯冲深度相对更深，利于形成深陷的盆地，其中以45°倾角对应的俯冲陆块一侧俯冲最深；当断裂带倾角≥75°时，两个大陆板块之间的相对俯冲和仰冲作用变得不明显。

In the dissertation, we presented a method to calculate the start oscillation length and real starting asynchronous velocity parameter. In the meantime, when the effect of two or more azimuthally asymmetric space harmonics in the high power broadband helix TWT on the start oscillation length and real starting asynchronous velocity parameter were also analyzed.

数值计算表明：增大渐变的强度，就可以增加起振长度，而且当渐变的强度增大到一定值时就不会产生返波振荡；当衰减器靠近输入段时，起振长度就随之减小；当增大衰减器的长度或减小衰减量时，相对起振电流随之减小，可见衰减器对起振条件确实有明显的影响。

It shows in clinic as tooth sensitivity, pulpitis,periodontitis,food impaction ,deformation of basifacial caused of loss of occlusal height, temporomandibular disorder syndrome, etc. The wear property of artificial tooth material will lead a direct effect to restoration result, when it exists in oral environment. It will cause tooth enamel loss too much in a very short period, if the wear property of artificial tooth superior to tooth enamel; but if it is inferior to tooth enamel, serious wear will occur on restoration occlusions, which will lead to loss of bite functions and even decrease of occlusal vertical dimension, disorder of bite functions, etc. Therefore, it is important to artificialtooth material not only it"s biotic compatibility, mechanical function, chemistry property but also it"s wear property.

当口腔中存在修复体时，人工牙材料的磨耗性能也直接影响临床修复的效果，当其磨耗性能强于天然牙釉质门时，将会引起天然牙釉质过度磨耗；当其磨耗性低于天然牙釉质时，又会在较短时期内引起修复体咬合面磨损过度，失去咬合功能，严重者甚至出现咬合垂直距离降低，咬合功能紊乱等症状因此，对于人工牙材料除了考虑生物相容性、机械性能及化学性能外，还应考虑到材料的磨耗性能，而磨耗率的测定一直是评价天然牙及人工牙磨耗性能的优越指标之一。

The results show that the introducing of multivinyl monomer and CaCO3 can slow down polymerization rate to different extent.Using 1％～5％ trimethylolpropane trimetbacrylateor divinyl benzene,tight encapsulation of CaCO3 can be realized and beyond 94％PS cannot be extracted. The amount of crosslinker or emulsifier should be accommodated when the load amount of CaCO3 is increased.CaCO3 content in the product increases consequently with the increase of the loaded amount of CaCO3,which can be known from FT-IR and TGA.TEM observations reveal that when the load amount of CaCO3 is 14.8％,most CaCO3 particles are encapsulated and each latex particle contains one CaCO3 particle.Composite particles have well-defined core—shell structure and the thickness of polymer shells is around 10 nm.However,the thickness of polymer shell decreases and many free CaCO3 particles appear when the load amount of CaCO3 reaches 29.3％and 58.7％,respectively.

结果表明，多乙烯基单体以及碳酸钙的引入会使聚合反应速率有不同程度的降低；使用1%～5%的TMPTMA或DVB，可实现PS对碳酸钙颗粒的牢固包覆，不可抽提的PS达94%以上；当碳酸钙用量改变时，需要适当调整乳化剂和多乙烯基单体的用量；IR和TGA的结果表明，随着碳酸钙用量增加，产物中的碳酸钙含量也相应增加；TEM照片和计算结果显示，当碳酸钙用量为14.8%时，绝大部分碳酸钙颗粒被包覆，且基本上每个乳胶粒中包覆一个碳酸钙颗粒，复合粒子具有清晰的核壳结构，壳层厚度约为10 nm，而当碳酸钙用量增加到29.3%和58.7%时，壳层厚度减小，并且出现较多裸露的碳酸钙颗粒。

Certain things become clear to me when I'm running-only while running did I realize that "hippopotami" is possibly the funniest word in the English language, and only while running did I realize that the travel section of The York Times does not necessarily provide an accurate depiction of the entire world.

当我跑步时，有些事情对我会变得清晰。只有当我跑步时美国留学生美国留学签证，我才意识到，河马可能是英语里最搞笑的单词；只有当我跑步时，我才意识到《纽约时报》的旅游版并不一定提供了对整个世界的准确描绘。

What he wanted for Sydney was the effect he had noticed when tacking round the promontory at Elsinore, of the castle's piled-up turrets against the piled-up clouds and his own billowing white sails; the liberation he had felt on the great platforms of the Mayan temples in Mexico, of being lifted above the dark jungle into another world of light; the height and presence of Gothic cathedrals, whose ogival shape was to show in the cross-sections of the Sydney roof-shells; and the curved, three-dimensional rib-work of boat-building , as he had watched his own father doing it at Aalborg.

当他在艾尔西诺海岬旁作之字形航行时，天边积云朵朵，海水蓝天融为一色，海风一过，巨大的白帆随之鼓起，城堡上层叠而立的塔楼在一片湛蓝中像条游龙飘忽不定。如此景致早已收藏于心。他所向往的悉尼巨作不正是这幅美景的再现么？当他伫立于墨西哥玛雅寺庙辽阔的平台之上时，那份无拘无束的洒脱正从昏暗的丛林中抽身而出，徐徐升腾，遁入另一个光的世界。这不羁的心不正是他想施予悉尼的么？还有那直插云霄的哥特式大教堂，它们的伟岸和雍容时时撞击着他，剖开未来悉尼歌剧院的扇形穹顶吧，横截面上所展示的不正是带着尖顶拱的外形么？当他在奥尔堡傻傻地看着父亲建造船坞时，那有着优美弧线的三维肋拱结构不也是激活他未来创作的源泉么？

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.
