Petrochemical industry Rising stem resilient gate valve majopplications API standard gate valve, globe valve and check valves; electricity sector, mainly in power stations using high-temperature pressure valve, globe valve, check valve and safety valve, and part of the low-pressure water supply and drainage valve butterfly valve, gate valve; chemical industry is mainly made of stainless steel valve, globe valve, check valve; metallurgical industry Forged steel welding gate valve mainly uses low-voltage large-diameter butterfly valve, oxygen valve and oxygen valves; urban construction department used mainly low-pressure valve, Such as urban water supply pipeline used mainly large-diameter valve, floor, blending the building of the center line butterfly valve used mainly in urban heating primarily metal sealing butterfly valve; oil pipeline used mainly flat gate valve and ball valve; the pharmaceutical industry mainly uses stainless steel ball valve; the food industry mainly uses stainless steel ball valve and so on.

石化行业主要应用API标准的闸阀、截止阀和止回阀；电力部门主要采用电站用高温压闸阀、截止阀、止回阀和安全阀及一部分给排水阀的低压蝶阀、闸阀；化工行业主要采用不锈钢闸阀、截止阀、止回阀；冶金行业主要采用低压大口径蝶阀、氧气截止阀和氧气球阀；城市建设部门主要采用低压阀，如城市自来水管道主要采用大口径闸阀，楼寓建设主要采用中线蝶阀，城市供热主要采用金属密封蝶阀；输油管线主要采用平板闸阀和球阀；制药行业主要采用不锈钢球阀；食品行业主要采用不锈钢球阀等。

By theory analyzing and example calculation and comparison, the conclusion is obtained that the traditional inferential method can be applied in the design flood peak flow calculation, yet it cannot truly express the runoff process of the rain drainage inlet, the instantaneous unit hydrograph depending on the real and actual datum is different to be used in the runoff discharge hydrograph calculation, and the no linearity reservoir means and the isochronal method have some physics base and its parameters easily evaluated and its runoff discharge hydrograph still more is close to practice.

5通过城市雨水地表汇流特性及计算方法的理论分析、实例计算和对比得出：传统推理法可应用于城市设计洪峰流量的计算，但不能真实地反映雨水口径流流量过程；瞬时单位线法等对实测资料有较大依赖，难以应用于城市径流流量过程线的计算；非线性水库法和等流时线法的径流流量过程线接近实际。

With the inducement of market economy, there are large-scale urban construction, for example, increasing of the urban population continuously, absenting the land gradually, and promoting the extensive urban housing construction. Comprehensively, which bring many puzzling issues in China, especially in recent years since the open policy was carried out.

在市场经济利益的引导下，我国城市大规模的建设，这带来很多问题，例如城市人口不断增加，土地的稀缺性逐渐显现，大规模的城市住宅建设全面推进。

These were partly due to the explosion in population, but also to concentrate economic power at strategic locations, while formerly cities only existed in the shape of either old Roman foundations or older bishoprics.

这一部分是因为人口膨胀而造成的，但也是为了集中战略地域的经济力量，当传统的城市仅仅建于古罗马或者早期教区的基础上。12世纪建立的这些城市中包括作为后来许多城市的经济典范的弗莱堡和慕尼黑。

As Lee McIsaac has shown, when Shanghai urbanites got to Chongqing in late 1938, they looked down on Chongqing residents as country bumpkins, even though they lived in the cultural heartland of southwestern China (see "The City as Nation: Creating a Wartime Capital in Chongqing" in Joe Esherick's edited volume, Remaking the Chinese City ).

李 mcisaac 表明，当上海城市居民到了重庆，在1938年年底，他们看不起对重庆市居民作为国家 bumpkins ，即使他们住在文化中心地带的中国西南地区（见&城市作为国家：建立一个在战时资本重庆&在 Joe esherick 的编辑量，重塑中国城市）。

It can be applied in planning consulta- tion business and information-generated seminars. Information resource,Planning consultation,Planning management,Land market

在土地从资源向资本转变的市场化进程中，城市建设进入了一个全新、快速的发展轨道，城市规划管理方式也发生着日新月异的变化，对实现科学、高效的城市规划宏观调控功能的要求也日益迫切

There're cyclicity laws existing in between urban development and commercial development, each of which is the precondition and accelerant for the other. Furthermore, there're co-matching adaptability laws for developing harmoniously; growing laws for urban forms development and commercial formats transformation; and the radiation laws, which come into being in the course of the co-influence among the cities.

在城市发展与商业发展之间，存在着互为前提，相互促进的周期性规律；存在着相互匹配，协调发展的适应性规律；存在着城市形态发展和商业业态变化的成长性规律；存在着城市间相互影响的辐射性规律。

Compared to other models pointed out by foreign scholars, my model was characteristic of multiple periods during evolution of urban systems, complexities of the course of forming urban systems, multiple types of urban functions, periodicity of regional changes of the important regions of urban development, periodicity of dominances of inland central city and seaport gateway city.

此后，随着海疆由开启转为封闭，再由封闭转为开启，最大城市由青岛转为济南，再由济南转为青岛；中心地职能体系由&青岛单中心体系&转换为&青岛、济南双中心体系&，再转换为&青岛单中心体系&；工业发展重点区域也由沿海转向内陆，再由内陆转向沿海；口岸城市的门户职能强度也经历了增强、减弱、增强的不对称&U&型变动；城市体系的空间结构经历了碎化—整合—碎化的过程。

GBD-Beijing's new map is located in the East along its urban centers located in conjunction with the exurb of the new city map, Set in a variety of styles and inclusive from the Beijing city cultural increased the Gaobeidian cultural district.

GBD 地处北京市新地图的东沿，它定位于城市中心与卫星城结合部的新版图城市，集多种样式于一身，并包容在从北京城市文化中上升的大高碑店文化里。
