In this part, carrier interferometry technique is combined with MIMO-OFDM architechure, resulting in the so called MIMO-CI/OFDM system. It is shown that the novel system can achieve dramatic performance gains by taking advantage of large frequency diversity inherent in the CI/OFDM technique. Further more, the proposed MIMO-CI/OFDM system has a more stable envelope and, ultimately, an average PAPR far smaller than that of MIMO-OFDM.

将载波干涉技术与多天线OFDM技术相结合实现了一种MIMO-CI／OFDM结构，由于CI／OFDM具有大的频率分集作用，该结构因而获得显著的性能增益；而且由于采用CI技术使得发射信号的包络更加平稳，与原有的MIMO-OFDM系统相比具有较低的PAPR。

In this paper, an extended divide and conquer algorithm is intended proposed, which is for solving the real symmetric band generalized eigenvalue problem under distributing environment Eigenvalue partition theorem is presented and proved Based on divide and conquer by extension, this algorithm computes generalized eigenpaires of symmetric band matrix pencil by bisection and generalized Rayleigh quotient iteration Theoretic analysis and numerical results show that this algorithm is better than the classic software package LAPACK when bandwidth is small and the scale is large Combined with multisection, which has good parallelism, it got good effects under distributed environments

Tuesday, a little slip changed the course of a ballgame, as Robertson was tagged for five runs on six hits in an explosion that sparked an 8-4 Yankee win that put Detroit in an 0-1 hole.

星期二，小小滑了一跤改变了球赛的结果，而萝卜生在一次打击大爆炸里被打出六支安打掉了五分，让洋基获得8比4的胜利也让老虎落入0胜1负的情况。

They also challenged the forces of Timothy and Bacchides, killed more than twenty thousand of them, and captured some very high fortresses. They divided the enormous plunder, allotting half to themselves and the rest to the persecuted, to orphans, widows, and the aged.

他们又与提摩太和巴基德的军队交战，杀死了他们两万多人，并且也占领了几座很高大的堡垒，将获得的无数战利品，平均分为两分：一份为他们自己，一份为受害的人、孤儿、寡妇和老人。

Time graded schemes such as over-current or distance protection schemes are examples of those providing inherent back-up protection; the faulty section is normally isolated discriminatively by the time grading, but if the appropriate relay fails or the circuit breaker fails to trip, the next relay in the grading sequence will complete its operation and trip the associated circuit breaker, thereby interrupting the fault circuit one section further back.

过流保护或距离保护可作为前一种方案的例子，通常采用分时限区别来隔离故障段，如果相应的继电器拒动或断路器拒跳，按时限下一个继电器动作跳开有关的断路器，这样就断开了故障回路的下一段。采用这种方法就获得了完整的后备保护。

The most important factor influencing implant survival in sinus augmentation, besides individual surgical technique, is the preexisting bone height between the sinus floor and alveolar crest. The key factor for success is to achieve primary stability. When the available bone height is less than 5mm or the thickness of the cortical bone is inadequate, two stage protocol (elevating the sinus floor to create sufficient bone height first, and then placing the implant at the second stage) is a safe, predictable treatment modality.

上颚窦植牙手术的成功与否，除个人手术技巧外，常取决於剩余齿槽骨之高度(residual bone height， RBH)，如何得到初期稳定度是一重要之关键，当可利用之齿槽骨高度小於5mm或皮质骨宽度不足以支撑植体获得理想初期稳定度时，分二阶段先提高上颚窦高度再植牙，不失为一理想，安全且可预期性高之植牙方法。

The categories and types that we isolate from the world of phenomena we do not find there because they stare every observer in the face; on the contrary, the world is presented in a kaleidoscopic flux of impressions which has to be organized by our minds 2）any influence is ascribed not to 'Language' as such or to one language compared with another, but to the use within a language of one variety rather than another (typically a sociolect - the language used primarily by members of a particular social group); 3） From the media theory perspective, the sociolects of sub-cultures and the idiolects of individuals represent a subtly selective view of the world: tending to support certain kinds of observations and interpretations and to restrict others.

After all the angular integrations and spin summations completed, the needed parameters in the non-relativistic wave functions have been acquired using the variational method and so the functions themselves have been established in this way.

在第三章中，利用对角和法则，导出了类硼离子基态及第一激发态非相对论能量的解析表达式，完成涉及到的角向积分和自旋求和后，利用变分原理求出了非相对论性波函数中的待定参数，从而确定了非相对论性波函数，并获得类硼离子基态及第一激发态非相对论能量。
