While we were trying to understand the origin of subcontinental mantle anisotropy by SKS splitting measurements in Qinghai-Xizang plateau, we were perplexed for answers to the following questions:(1) why the inefficient Sn propagation region correlates with the large delay time (1.91-2.40s) of SKS splitting,(2) why very strong δt variations occur at the edges of this region, and (3) what results in the abnormal delay time.

当人们试图解释青藏高原异常的剪切波分裂成因时，以下的问题让人们感到困惑：为什么异常大的SKS分裂延时(1.91-2.4s)出现在青藏高原北部Sn波缺失区；(2)为什么分裂延时突变（1.47s和1.09s）出现在Sn波缺失区的边缘；(3)为什么快波极化方向与地表大规模的构造走向之间存在约20°-30°的偏差。

Firstly, the distance between stocks are calculated by using prices of stocks, and subdominant ultra-metric space by associating the minimum spanning tree of portfolio. Secondly, the subdominant ultra-metric space to the chart of index hierarchical structure is transformed, and finally the distribution of style is gained. Using sample of Shanghai Stock 50 Index from 2004 to 2007, the demonstration result shows that style of industry is more prominent horizontally, especially in the bank and steel industries. The style of region and cross holding also exists. And after the reform of non-tradable shares, style of industry becomes more obvious vertically and more other styles also occur.

首先利用股票价格计算出股间距离，并采用关联该证券组合的最小生成树优化方法，从而得到亚超度量空间；其次将此亚超度量空间转换成指数分层结构树图，最后得到风格的分布特征。2004~2007年的上证50实证结果表明：横向来看以行业分类的风格较为显著，其中以银行和钢铁也最为明显，此外还有与地区差异、交叉持股相关的风格效应显现；纵向则在股改后行业风格效应更显著，其它的风格也显现得更多。

As this plate continues to subduct or dive beneath the plate next to it, more eruptions will undoubtedly occur...

随着这个板块继续潜没或潜入其相邻板块之下，将会毫无疑问地发生更多的喷发。。。

With an increasing percentage of future subsea production expected to occur in ultra-deep water, suppliers to t...

简介： 随着未来超深水在海上采油中的采油量所占比例越来越大，世界上的油气供应商不断开发新技术，以使超深水采油更加经济，风险更低。

Which of the following can be inferred about the theory of plate tectonics? It is no longer of great interest to geologists. It was first proposed in the 1960's. It fails to explain why earthquakes occur. It refutes the theory of the existence of a supercontinent.

解析：根据原文末段末句，在1960's以前地质学家没有办法解释，而在之后tectonics理论给出了解释，于是可以推断这个理论在1960年推出，典型的"取非"细节推断题。

She graduated two years before they asked how such a big change to occur, she smiled suspire said to be only as a sales girl for her "downsizing".

问她怎么才毕业两年就发生如此大的变化，她微笑着叹气说是当了售楼小姐才让她"瘦身"的。

Besides, terminal synapsis was observed to occur in the meiosis of spermatocytes based on the analysis of signal distribution of 5S rDNA on chromosomes obtained from testis.3. 18S rDNA and histone gene h3 were mapped to the chromosomes of C.

此外，通过对5S rDNA在精巢染色体上信号分布特征的观察，认为中国明对虾的同源染色体在第一次减数分裂中期可能发生了末端联会。3。

During the preparatory periods of the Haicheng earthquake and Tangshah earthquake, the occurrences of the stronger earthquakes in the precursory field were related to the moon's phase, the M_L≥4.5 earthquakes of the near-focus field in the trend precursory periods and the M_L≥4.0 earthquakes of the whole precursory field in the periods of the fast-changing precursors tended to occur around syzygy or quarter.

海城和唐山地震的孕震期间，前兆异常区域内的较强地震趋于发生在朔望和上下弦，海城和唐山地震的主序列以及前兆异常区域内1900年以来发生的六级以上强震与月相也存在类似的相关。这些关系可以在地震预报中作参考。

Would love to have a Feat to recognise having completed (pet + tabard) the '08 Spirit of Competition event, since this event is unlikely to occur for another few years.

Q：不知会不会火星，我是说成就系统是否包括这次奥运奖励的背心和宠物竞争之魂？这个恐怕在最近几年不可重现。

Machining is sometimes done on the actual surfaces as opposed to tessellated surfaces to obtain a higher quality output. However, quality problems sometimes occur with high-speed machining, as the material can overheat, cracks can develop and the material can move.

为了得到更高质量的零件，高速加工有时是在实际工件表面上而不是网格状表面进行的，但是在材料过热、裂缝扩展以及移除材料过程中，高速加工有时也会出现质量问题。
