原因与结果

Elegans were significantly decreased after exposure to ENIs（p.05）; also the brood size and the lifespan of C. elegans were significantly reduced after exposure to ENIs（p.05）. Moreover, after exposure to ENIs, the lifespan of mev-1 mutant hermaphrodites was shorter than that of wild type（p.05）, indicating that mev-1 gene mutant could result in more sensitivity of the mutant hermaphrodites to ENIs exposure than the wild type.

结果表明：空气负离子暴露可显著加速野生型和mev-1突变型线虫发育（p.05），缩短寿命（p.05），与野生型相比，空气负离子暴露对mev-1突变线虫寿命影响更大（p.05）；空气负离子暴露可显著降低线虫后代数量（p.05），原因可能在于空气负离子暴露显著诱导性腺细胞凋亡的增加（p.05）。

It is not only the result of the influences of the transformation of immigration with "European characteristics" to that with "non-European characteristics" and changes of immigration culture, but also the result of economic recession and inconstant politics and immigration policies in the European mem...

这既是进入欧洲国家的外国移民由&欧洲特点&向&非欧洲特点&转变、移民文化变更因素的结果，也有欧洲国家自身经济衰退、政治与移民政策摇摆不定的原因。

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。

Despite this change occurred for special incident, it was not completely accidental. Cen Chunxuan advanced with the political situation because of subjective and objective factors.

这种政治上的转变虽然可说是不得已而为之，但并不是偶然发生的，是在主客观两方面原因促成下，岑春煊一直能够与时而变所导致的结果。

Thus,whilethe Bueno de Mesquita results demonstrate that wars are usually consistentwith rational behavior on part of the aggressors, his model does notexplain why wars actually occur since it does not explain why the loserfought.

因此，尽管德梅斯基塔的研究结果证明了战争通常与侵略者一方的理性行为相一致，但由于他的模型并没有解释失败者参战的原因，因而实际上也就没有解释为什么会发生战争。
