吸引性

Chapter 6, consider a coupled generalized KdV-Burgers equation. In section 6.2, we study the initial-boundary value problem in the semi-unbounded domain, the existence of global solutions and global attractors is proved by means of a uniform priori estimate for time. In section 6.3, the Cauchy problem by using the weighted space, the existence of the global attractors for a coupled generalized KdV-Burgers in an semi-unbounded domain is proved.

在第二章中研究了一类具有时滞的捕食与被捕食系统，分析了系统的正不变集，运用了特征值理论得到了边界平衡点性质，当时滞很小时，得到了系统在正平衡点局部渐近稳定的充分条件，以及当T增加到T_0时，系统在正平衡点附近产生Hopf分支的充分条件；利用局部渐近稳定性加吸引性得到了边界平衡点全局渐近稳定性的充分条件，且应用一致排斥定理得到了种群持久生存的条件。

Satio and Takeuchi proposed this model and then they establishedsu?cient conditions for global attractivity of an interior equilibrium.

Satio和Takeuchi提出了该模型并且给出了保证全局吸引性的充分条件。

However, due to the substantially different allocation of resources in various geographic regions, along with their own characteristic formation, agglomerate economies show rather a strong tendency of unhomogeneity, which leads to the unhomogeneous characteristics of their advantages regarding FDI attraction. Therefore, this paper proposes there exists an interactive relationship between the primary advantage and the multi-level agglomerate advantages by dividing the latter one into original agglomerate advantage and late-developing agglomerate advantage.

本文认为虽然随着经济全球化和信息技术的进一步发展，基础性优势的重要性逐步下降，从一种显性优势转化为潜在优势，是东道国吸引FDI的一种比较优势，集聚性优势则起着越来越重要的作用，是东道国吸引FDI的一种竞争优势，两者之间存在着质的差别，但作为分别作用于国家和次国家两个不同层面上的优势，基础性优势和集聚性优势之间存在着互动互补关系，基础性优势是集聚性优势形成的前提，集聚性优势则是对基础性优势的提升，两者共同构成了东道国吸引FDI的二重优势，在东道国吸引FDI中缺一不可。

Furthermore, we found that the Sema3F-triggered growth cone attraction was abolished by inhibition of the cGMP signaling pathway but not by inhibition of the cAMP signaling pathway, and the attraction was suppressed when elevating the intracellular cGMP level.

而且，在组织块共培养中，分泌Sema3F的细胞团能使小脑颗粒细胞偏向它迁移。我们发现Sema3F的吸引性作用在cGMP信号通路被抑制时受阻断，在细胞内cGMP水平增加时被削弱。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
