The electronic structures of cluster Fe8 with D6h symmetry and Fe15 with Oh sysmmetry have been studied by MS-X method..The results show that(1 the exchange splittings of the d-band and the magnetic moments of the Fe-atoms are different in the two clusters;(2)the change distribution in both clusters is not uniform,showing that the electrons are transferred from peripheral atoms to inner atoms,and the spin-directionof the electrons transferred is in accordance with the symmetric characteristics...

用MS-Xα方法研究了Fe8原子簇（具有D6h对称）和Fe15原子簇的电子结构，结果表明：（1）两种原子簇中的Fe原子磁矩及其d能带中的交换劈裂性质互不相同；（2）两类原子簇中的电荷分布不是均匀的，电荷倾向于从外围原子向内部原子上转移，并且被转移电子的自旋方向与原子簇的对称性质密切相关。

This principle originated from the system of ""one record did not bring a case to court two times "" in the ancient Rome law, and developed along different directions in two genealogies of law. In Common Law System, it named ""Non Bis In Idem""; and in Civil Law System, it named ""the principle against double jeopardy"".

它起源于古罗马法中的&一案不二讼&的制度，在两大法系沿着不同的方向发展，分别成为大陆法系既判力式的一事不再理原则和英美法系的禁止双重危险原则，其共同之处在于保护被告使其免于基于同一事实的国家权力的两次追诉。

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。

But of course everything else about the Nile is different, like a scene from the Babar children's books. It has not been tampered with.

当然除此之外这里的尼罗河都是那么的不一样，就像Babar儿童读物中的一幕，一丝一毫也不曾被篡改过。

To call Levitt a "rogue economist" may be a tad hyperbolic. Certainly this epitome of antistyle ("his appearance is High Nerd: a plaid button-down shirt, nondescript khakis and a braided belt, brown sensible shoes") views the workaday world with different eyes; the young economist teases out meaning from juxtapositions that simply would not occur to other researchers.

如果称列维特为'流氓经济学家'也许有点夸张，当然这个反流行的典范（&他的外表相当讨厌：一件领尖订有钮扣的衬衫，极普通的卡其裤，一条麻花状的腰带，褐色的鞋子&）以不同的眼光看这个世界；这位年轻的经济学家轻易便能从并列的事物中发现其他研究者所不能发现的意义。

Before starting our tour of monticello, i'd like to give you some historical facts that might help you appreciate what you see today even more Monticello was very much loved home of thomas Jefferson for over fifty year Jeferson who was ,of course president,was also a great reader and language enthusiast he read widely on different subjects including architecture ,he wasn'tt formally trained in architecture but as a result of his study and observation of other bulidings he was able to help design and build the house he chose the site himself, nameing the estate"Monticello" which means"little mountain"in Italian in fact many of ideas behind the design also came from the Italian architect Andrea Palloadio who lived in the sixteenth century and who had a great influence on the architecture of england Jefferson,however,ignored one of Palladio's principles that is , not to bulid in a high place Monticello's elevation made the transportaion of what was needed at the house for example food --- especially difficult.

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
