The results showed that the statistical characteristics and changing regularity of the integer multiple spiking from the experiment were similar to those from the stochastic Chay model, but different obviously to those from the deterministic Wang model.

结果发现，实验和随机模型经随机自共振产生的整数倍峰放电节律具有相同的统计性质(峰峰间期越大，出现的频度越低，约呈指数递减)和变化规律，与确定性Wang模型产生的整数倍节律明显不同。

The results show that the period-adding bifurcation obeys the deterministic mechanism decribed by Chay model and lightly affected by stochastic factors. In the corresponding parameter region, the integer multiple spiking generates only when the stochastic factors are introduced to the model. The phenomenon is autonomous stochastic resonance.

从模拟实验结果的角度看，加周期分叉过程遵从Chay模型决定的确定性机制，随机因素对其有影响但影响较小；而在相应的参数区间，整数倍节律则是在随机因素驱动下产生，是随机共振现象，是由确定性机制和随机因素共同作用的结果。

According to Sarkovskii's theorem, if the continuous self-map f of the closed interval has a 3-periodic orbit, then f must has an n-periodic orbit for any positive integer n But f can not has all n-periodic orbits for some n.

但f不可能有所有类型的n-周期轨。例如：则f仅有两种类型的3-周期轨中的一类。这表明Sarkovskii定理远远没有给出周期轨之间的关系的全部信息。

Firstly establishing mechanical model of casing structure , and then processing casing forces analysis using space finite-element method and superposition method(put structure stress and outer force stress together), it computes the stress of casing in three dimensions, and gets the internal force and transmutation. The structure of casing-coadjutor is computed overlaply and the question of contact is solved. In the aspect of design, it provides the mixed integer-discrete variable optimization method of casing cross section size and coadjutor layout.

本文就上述两个问题的最优化设计展开研究，首先建立了套管结构的力学模型，进行套管的受力分析，用了空间有限元法和叠加法(结构应力和外载应力相叠加)，对套管进行三维计算，确定结构的内力和变形，对套管—扶正器结构进行整体的叠代计算，解决接触问题；在设计方面，提出了解决套管截面尺寸参数和扶正器布局的混合整数—离散变量优化方法。

If cohomology with integer coefficients is used, so that

它在霍奇的著述的一个结果中出现，他在1930至1940年间通过包含额外的结构丰富了德拉姆上同调的表述，这种结构出现于代数簇的情况。

Ifσ: I→C is an incidence coloring of G and |C|=k, k is a positive integer, then we say that G is k- incidence colorable andσis a k - incidence coloring of G; The minimum value of k such that G is k -incidence colorable is called the incidence chromatic number of G, and is denoted byχ_i, namelyχ_i = min {|C||σ: I→C is an incidence coloring of G}.

若σ：I(G→C是G的一个关联着色且|C|=k，k是一个正整数，则称G是k-可关联着色的，σ是G的一个k-关联着色；使得G是k-可关联着色的最小的k值称为G的关联色数，记为X_i，即X_i=min{|C||σ：I→C是G的关联着色}。
