In preface, author discusses the meaning of this study and the actual state of research about culture of Tibetan oath at home and abroad. The first chapter analyzes two basic sources of oath culture. In the second chapter, by analyzing literature and actual examples, author explores the problem which the definition of "oath" is unclear in Tibetan dictionary. Combining with the definition of oath, in the third chapter ,the author differs the concept among promise, treaty, bargain and caution money. The fourth chapter is mainly about the element of oath; In the fifth chapter , author divides and explores the different content and meaning of Tibetan oath.

The closest period of time everyday the snapshot circumstance of the website, website already a few months Baidu from collect experienced 10 days now half month updates snapshot to arrive 24 hours to update again to a week, update a few pages to update several much pages to from, arrive 24 hours from 24 hours of a few pages the snapshot of 200 much pages, this paragraph of time understands eventually, to Baidu snapshot should update ability 24 hours to be have weight, baidu did not use PR value to measure the weight of a website like Gu Ge, what does that use, I feel to return is the time that snapshot updates, the jump overing that a website updates in 24 hours has weight more more, because do not think what giving just is Baidu weight really, cannot use PR to see, of course this is pure belong to an individual close a point.
最近一段时间每天网站的快照情况,网站已经几个月了百度从收录到现在经历了十天半个月更新一次快照到一个星期再到24小时更新,从一次更新几页到一次更新数多页,从24小时几页到24小时200多页的快照,这段时间终于明白,对百度来说快照要24小时更新才算是有权重,百度没有像谷歌一样用PR值来衡量一个网站的权重,那用什么呢,我觉得还是快照更新的时间,一个网站在24小时更新的越多就越有权重,因为实在想不出什么才是百度权重,不能用PR一下看出来,当然这纯属个人的关点。

The Tanner Lectures were established by the American scholar, industrialist, and philanthropist, Obert Clark Tanner. In creating the lectureships, Professor Tanner said,"I hope these lectures will contribute to the intellectual and moral life of mankind. I see them simply as a search for a better understanding of human behavior and human values. This understanding may be pursued for its own intrinsic worth, but it may also eventually have practical consequences for the quality of personal and social life."

In chapter 2 and 3, experimentally, using the Angular-Resolved high-resolution fast Electron Energy Loss Spectrometer , at the condition of 2. 5 keV incident energy and 50-60 meV energy resolution, we measured the Optical Oscillator Strength Density Spectra for the excitations of 4p, 4s or 3d electron. The oscillator strengths for excitations of the valent shell 4p electron were obtained, and comparisons were done between presently experimental and previously experimental and theoretical results. The experimental results of different groups agree with each other approximately, but the semi-experientially theoretical results do not match with the experimental results. The delayed maximum in the photoabsorption spectra was discussed. It should arise from the transition of 4p→∈d. For the excitation of the inner-valent 4s electron, the discrepancies for the resonant structures in previous electron-impact results and photoionization results were clarified in present work, which confirms again that the fast electron impact method is suitable to measure the optical oscillator strengths. The autoionization Rydberg series 4s〓ns (n=5, 6, 7) and 4s〓nd (n=4, 5, 6, 7) were identified without ambiguity by the measurement at 0°, 2° and 4°scattering angles. The energy levels and natural widths of the excitations of Kr3d and Ar2p inner shell, including optically allowed and forbidden transitions, were determined. The widths of these inner shell excitations are nearly the same, which was interpreted by the Resonant Auger effect .
在第二章和第三章,实验上,使用角分辨的高能量分辨快电子能量损失谱仪,在2.5keV电子入射能量和50-60meV能量分辨下,测量了Kr原子由价壳层4p到内价壳层4s,再到内壳层3d电子激发的光学振子强度密度谱;得到了价壳层4p电子激发束缚态的光学振子强度,与前人实验和半经验理论结果作了细致的比较,说明几家实验是比较符合的,但半经验的理论计算存在问题;分析了光吸收谱中的延迟极大现象,说明在第一电离阈值以上几个eV范围内的极大值源于4p→εd跃迁产生的延迟极大;对于内价壳层4s激发的自电离区,澄清了前人实验中电子碰撞方法和光学方法在共振结构上存在差异的问题,再一次肯定了快电子碰撞方法是获得绝对光学振子强度的一种好方法;通过在非0°散射角的测量(如2°和4°),清楚地标识了4s电子激发的光学禁戒跃迁自电离里德堡系列4s〓ns(n=5,6,7)和4s〓nd(n=4,5,6,7);通过在0°和4°散射角的测量,观测并标识了几个新的内壳层光学禁戒跃迁能级,得到了Kr原子3d和Ar原子2p内壳层激发态(包括光学允许和禁戒跃迁形成的)的能级位置和自然宽度,用共振俄歇效应解释了这些内壳层激发态(不管是光学允许还是禁戒跃迁产生的)的自然宽度彼此比较接近的原因。
