多中心的

It means that the city's spatial expansion has not been supported effectively by the transportation system. The polycentric industrial areas and the annularly distributed population do not match spatially.

具体而言，广州市多中心的产业增长和圈层式的人口分布在空间上不匹配，城市未来钟摆式通勤交通的压力将不断加大，而单中心放射状的"双快"交通系统在解决这一问题上是失效的；另外，"双快"系统不利于外围新城市副中心的建设，相反由于与中心城区的快速联系，有可能将大量的人口留在中心城区边缘，给中心城区带来巨大的服务压力。

Objective: Through the clinical and experimernt study of many centres of the method of cauterization cure chronic tonsillitis to appraise curative effect of this therapy.

目的：通过对中医烙法治疗慢性扁桃体炎多中心的临床与实验研究，科学评价该疗法的有效性和安全性。

Methods 265 cases gathered from multi-centric clinic were studied through layerage and cross-section by using the method of data mining such as free-scale-networks, and so on.

采集来自多中心的临床病例，运用无尺度网络等数据挖掘方法对其进行分层、横断面研究。

Its structure has already developed from simple star topology ,which is used to serve schedular center, to todays multicenter network to assure that the network can serve the requirement of increasing transmission of electric power information.

电力通信网的结构也已从单一服务于调度中心的简单星形方式发展到今天多中心的网状网络，以保证能为日益增长的电力信息传输需求服务。

Its structure has already developed from simple star topology , which is used to serve schedular center , to today ' s multicenter network to assure that the network can serve the requirement of increasing transmission of electric power information

电力通信网的结构也已从单一服务于调度中心的简单星形方式发展到今天多中心的网状网络，以保证能为日益增长的电力信息传输需求服务。

So here we have a very large multi-center randomized control trial that show you really need 24 weeks of therapy.

所以我们需要根据24周的治疗疗程再进行多一些多中心的随机对照组研究。

In this section, applying the method, from abstract to specific and from history to present, it analyzes the operation mechanism of urbanization economy affected by market mechanism; puts forward four theories of urbanization economy from economic perspective, including agriculture surplus and comparison advantage; non-agricultural industry; agglomeration economy and spillover effect, on this basis of the theories, it, on one hand, analyzes two kinds of internal mechanism in the chronologic operation of urbanization economies: increasing mechanism of urbanization economies in urban output industry; and changing mechanism from specialization to integration, which are the representations of the evolution of "mart" development; on the other hand, it analyzes two internal mechanism of dimensional operation of urbanization economy: internal spatial enlargement mechanism of urbanization economies from monocentric city to multi-center city, and external spatial enhancement mechanism which represents city-regionalization and city-chain connection, the later two mechanism represent the evolution of "polis" development.

这一部分，按照由抽象到具体和由历史到现代的研究方法，分析了市场机制作用下的城市化经济运行机理，从经济学角度提出了农业剩余与比较优势、非农产业、聚集经济、外溢效应四大城市化经济定理；在此基础上，一方面分析了城市化经济运行沿时间增长的两个内在内容提要机制：城市输出产业的城市化经济增长机制和从专业化到综合化的城市性质变迁机制，它们主要表现为&市&发展的延续；另一方面分析了城市化经济运行沿空间增长的两个内在机制：从单中心到多中心的城市化经济运行的内部空间扩展机理和表现为城市区域化、城市连绵体的城市化经济运行的外部空间扩展机理，它们主要表现为&城&发展的延续。

Methods: An open,multicentral clinical trial was conducted in 100 patients with BPH.

为了进一步评价爱活尿通治疗国人BPH的安全性和有效性，2004年7月至12月，我们对该药进行了为期12周的开放性、多中心的临床研究，现报告如下。1对象和方法1.1试验设计采用开放性、多中心的临床研究。

In a randomized, multicenter trial, 341 patients with moderate or extensive bullous pemphigoid received large doses of high-potency topical corticosteroids -- either topical clobetasolpropionate cream (40 g per day) or oral prednisone (0.5 mg perkilogram of body weight per day for those with moderate diseaseand 1 mg/kg/day for those with extensive disease)-- applied over their entire body.

在此次追踪多中心的试验中，341位中度或广泛性大水疱性类天疱疮患者接受大剂量较强外用皮质肾上腺类脂醇全身治疗──使用外用clobetasol propionate乳剂（40g/日）或者口服prednisone（中度患者0.5mg/千克体重/日，重度患者1mg/千克体重/日）。

For this, we recommend a multicenter, randomized clinical trial.

因此，我们提议开展一个多中心的随机临床试验。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
