其表现为：古典时代的民主思想在中世纪继续得到发展，古典时代的民主遗风制约中世纪各种君主制度的演变，古代社会所形成的体现权利与义务关系的社会契约规范着中世纪的权力关系，城市自治与市民社会也约束着君权并推动民主化进程。

Here, the pale clergyman piled up his library, rich with parchment-bound folios of the Fathers, and the lore of Rabbis, and monkish erudition, of which the Protestant divines, even while they vilified and decried that class of writers, were yet constrained often to avail themselves.

面色苍白的牧师在这里摞起他的丰富藏书，其中有对开桑皮纸精装本的先哲们的著作、拉比④们记下的传说、以及许多僧院的考证——对这类文献，请教教士们尽管竭力诋毁，却不得不备作不时之需。

SHRIMP technique is applied to the age determination of Shuiquangou alkalic complex. Zircons from monzonite and syenite of the complex in the Dongping and Hougou gold mining district are dated at age of (390± 6) Ma and (386±6) Ma, respectively with U-Pb method. Rock-forming times of the complex is confidently constrained in the Late Caledonian-Early Hercynian period.

Based on the problem of singlestage network bottleneck capacity expansion, according to different criteria, we bring forward three kinds of multistage network bottleneck capacity expansion programming, including expected value model, Chance-constrained programming model, and Dependent-chance programming mode, apply dynamic programming approach to deal with those multistage problems, and come out with the relevant hybrid intelligent algorithm in the third part i.e.

基于第二部分的单阶段网络瓶颈容量扩张问题的基础，本文的第三部分根据不同的准则，提出了三种随机型多阶段网络瓶颈容量扩张规划，包括期望值模型，机会约束模型，相关机会模型，我们通过应用动态规划的方法来处理该多阶段的问题，给出了相应的混合智能算法。

Color image sequence is presented by multivectors in geometric algebra,it is proved that if meet the constrained conditions for color optical flow analysis,a multivector instead of multichannel image processing method can be used to represent the continued distribution of images to expand the measurement range.

在几何代数域内对彩色图像序列用多重矢量表示，证明了彩色光流场分析时进行约束条件时的测量问题，通过多重矢量而非多通道的图像处理方法来表示图像连续特性，从而扩大了测量范围；然后依据物体色彩在运动过程中保持不变的原理，在几何代数域内推导了彩色图像序列的光流约束方程及其解法。
