集聚

To keep certain number of greater patches through protection and restoration in urban area is meaningful;(2) small greenland patches with diverse structure may promote the heterogeneity of urban landscape, and serve as colonial land and stepping stones for certain populations, and create rich types of habitats and ecological niches. So laying small patches in urban environment is also important. Incorporation of the coarse grain and fine grain, aggregation and outliner of landscape elements may creates better landscape patterns;(3) many literatures have showed that good landscape connectivity benefits the longer persistence of species and the conservation of biodiversity.

大的绿地斑块有多种作用，通过城市地区自然景观斑块的保护或城市绿地的建设，在城市中维持一定的较大规模的绿地斑块是有积极意义的；（2）结构不同的小的绿地斑块可增加城市的景观异质性，为生物提供迁徙地、扩散暂歇地，创造丰富的生境资源和生态位，因此，结合大的绿地斑块的建设，同时布置小的绿地斑块作为补充，粗粒、细粒结合，集聚、分散结合是形成优良绿地景观格局的途径；（3）诸多的文献已显示，好的景观连接性有利于物种持续较长的时间，从而有利于生物多样性的保护。

They also enabled us to conduct the comparisons of cross-industry and cross-location.In addition,the latest distance-based measurement method proposed by Duranton and Overman(2005) meets many industry measurement requirements.

此外，最新的Duranton和Overman(2005)基于距离提出的测度方法虽然满足了产业集聚测度的众多要求，但囿于对数据的要求过高，实用性不强。

Note: In particular, a pondage station permits the cumulative water flows to be stored during periods of low load to enable the turbine to operate during high load periods on the same or following days.

由径流量向水库蓄水时间最多不超过几个星期的水电站。注：特别是低负荷期间，径流量集聚在水库中，以便水轮机在日后的高负荷期间或随后的数天内能够运行。

There is a common postulation that geographic concentration will increase the productivity of the firms and make them accelerate competition and finally induce a higher industry concentration ratio.

一般研究认为企业在空间布局上的集聚将提高生产效率，使得企业间竞争加剧，最终导致产业集中度上升。

In the view of Macker Pott, a professor of University of Harvard, USA, the industrial cluster means a phenomenon that in a specific field (usually with one leading industry as the core) a large number of interrelated enterprises and support organizations concentrate in space and form a strong and continued competitive excellence.

按照美国哈佛大学迈克尔·波特教授的观点，产业集群是指在某一特定领域中(通常以一个主导产业为核心)，大量相互关联的企业及支撑机构在空间上集聚，并形成强劲、持续的竞争优势的现象。

All of these will contribute to make our program the "sacred land" of China's silver industry and the "rallying point" of the imported silver.

这些都将使本项目最终成为中国白银产业的"圣地"，国外白银产业进入中国的集聚地。

In the thermodynamic limit, the zeros accumulate nearly the transition point z_0 in the real axis and the density of zeros near z_0 determines the order of the phase transition.

在热力学极限下，配分函数零点在正实轴上集聚的那些点z_0给出了相变的位置，同时在z_0附近的配分函数零点密度决定了相变的类型。

The process can be visualized as a wavefront being reflected back and forth between the two ends of the laser, picking up more photons with each reflection.

这过程可以想象波阵面在两个激光终端来回反射，伴随每一次反射集聚更多的光子。
