First, the stations'timing process and the slot aligning are discussed. Second, the dissertation propose a resource request random access method based on feedback. The performances of this method are analyzed. Third, proceed from the considerations of the MAC protocol for the HFC system, a QOS-oriental scheduling algorithm for the MAC protocol based on dynamic TDMA is proposed. Simulation results show that the performance of this algorithm is better than that of the first come first service. Forth, two contention resolution algorithms ----p-persistent CRA and tree CRA, which are usually adopted in the HFC system, are summarized. The delay and characteristic are compared. At last, the dissertation introduces the function implementation of the MAC layer based on COM21 UPSTREAMS.

首先，讨论了基站的同步进程和时隙同步的实现；然后，本文提出了一种带反馈模块的资源申请信号随机接入方法，并对其进行性能分析；然后，从HFC系统的MAC协议出发，提出了一种用于基于动态TDMA技术的MAC协议的业务安排算法，计算机仿真结果表明其性能优于先到先服务法的性能；然后概述了常用于HFC系统的两种冲突解决算法——p-坚持冲突解决算法和树型冲突解决算法，比较两者的时延性能与特征；最后，介绍了基于COM21 UPSTREAMS协议的MAC层功能实现，给出了硬件框图和照片。

For the first time, we investigated the possibility of using non-minimal coupled scalar field (include Real and Complex scalar fields) as the candidate of dark energy---Quintessence or Phantom. A cosmological model droved by real scalar field with accelerating and decelerating, forever cycling and expanding was constructed. Classical and quantum wormholes with Tachyon fields were discussed in detail. The entropy of sphere symmetric black holes due to arbitrary spin fields was studied, and the proportional relations between entropy and fields degeneracy was derived. For the first time, we investigated the neutrino quasinormal modes of stationary black holes in the background of de Sitter space-time, and the quasinormal modes of Schwarzschild black holes with arbitrary spin fields. We also studied the quantum teleportation in the background of curved space-time for the first time.

中文摘要：我们首次研究了非最小耦合标量场作为宇宙暗能量－Quintessence、Phantom的可能性；构造了一个实标量场驱动的加速－减速无限循环，永恒膨胀的宇宙模型；详尽讨论了具有Tachyon场的经典和量子虫洞；研究了一般球对称黑洞缘于任意自旋量子场的熵，给出了熵与量子场简并度之间的正比关系；首次研究了deSitter背景时空下具有中微子场的稳态黑洞的似正规模与具有任意自旋场的Schwarzschild黑洞的似正规模问题；首次研究了弯曲时空背景下的量子通讯问题。

At Maxville, it was my first time to realiae that I am abroad and I am a foreigner, because there is seldom Asian-faced people, even during this Games period. It was my first time to go camping, live in the tent, and sleep in the sleeping bag. It was my first time to take part in a real Canadian's party, drinking and chatting; sometimes we played cards and paper-folding frog.

在Maxville我第一次感受到自己是在国外，我是个外国人，因为那里几乎没有亚洲面孔的人，即使在这次活动期间；第一次camping，住在帐篷中，睡在睡袋里；第一次参加真正加拿大人的party，喝酒、聊天，无聊时就打牌、玩折纸青蛙；第一次玩草地槌球，一手拿酒瓶，一手握球棒。

Barbara Kendall took part in her first Olympic Games in 1992 in Barcelona. In the "lechner" board category, she took her first Olympic title at the end of 10 regattas. This title was already a feat in itself, as it was the first for a female New Zealand athlete for 40 years. It also allowed Barbara to equal her brother Anthony Bruce, himself an Olympic windsurfing champion in 1988 and bronze medallist in 1984 (when it was a demonstration discipline).At the Atlanta Olympic Games in 1996, the competitions took place in the "mistral" category. This change in no way affected Barbara's performance, as she came second in the competition behind Lai Shan Lee of Hong Kong.

1992年坎德尔在西班牙巴塞罗纳参加了自己的第一届夏季奥运会，在这里，她获得了自己的第一枚奥运金牌，这也是40年来新西兰第一位女子奥运会冠军。1996年美国亚特兰大夏季奥运会上，坎德尔参加了米斯特拉级的比赛，她也获得一枚银牌，这枚银牌也使她荣膺当年的新西兰最佳运动员。2000年坎德尔在澳大利亚悉尼参加了自己的第三届夏季奥运会，这次她获得了一枚铜牌，也成为奥运历史上，获得帆船项目奖牌最多的运动员之一。

Of course, we can leave this anecdote with unbeliveable attitude or just a smile, bue we can continue to watch a series of "Playbacks": Dell get his first computer on his fifteen's birthday, then he disintegrated it with high proficiency; Sixteen - years- old's Dell can easily get thousands of order when he look for orders for one newspaper via the method of fractionized the market;there are three PCs in the backseat of the car ,Dell drove the BMW which bought by the money of sale the newspapers when his first day to register in the university;1984,DELL set up with registered capital of USD1000 in the university dormitory.The youth Dell considered to take a part in the unlimited career and left the university when his first year in the university without considering when the computer business increased very quickly. We involuntary sigh that the youth Americans's persist in pursuing interest, grasping the business opportunities, determination of doing when thinking and doing the best.

我们当然可以对这段趣闻将信将疑或者干脆一笑了之，但当我们继续看到这样一组&回放镜头&——15岁生日时戴尔得到了第一台电脑，随即将它解体完毕，动作完全是熟门熟路；16岁的戴尔在为某报纸联系订户时通过细分市场的方法轻松找到了数千张定单；18岁的戴尔开着卖报纸赚钱买的宝马汽车去大学报到第一天，后座里藏着三部个人电脑；1984年，DELL公司以1000美元的注册资金在大学宿舍里成立，电脑升级销售的生意成长得如此之快，年轻的戴尔开始考虑&全职&从事这一充满潜力的事业，并径自办了退学，当时他只读完大学一年级，由此我们便不由自主地感叹于这个美国年轻人对兴趣的追求、对商机的把握、想到就做的果断以及那种既然要做就抛掉一切去做到最好的执著。
