regional concentration
地区集中度
The results indicate that market concentration、regional concentration 、ownership structure and entry barriers de-termine the performance of individual industry, but capital intensity has insignificant effect on industry performance. 截面数据的回归结果表明,市场集中度、地区集中度、所有权结构以及进入壁垒基本决定了行业的绩效表现,而资本密集度对行业绩效的作用并不明显。 短句来源 “regional concentration”译为未确定词的双语例句

This article introduced an important step for heavymetal pollution control in electroplating—a centralized waste treatment(CWT),that is,regional concentration of various pollution sourceswith a centralized waste treatment system.The practical experiencesand feasibility analysis of CWT in Federal Republic of Germany,Japanand the United States showed that CWT was an effective method forcontrol of heavy metal wastes,especially in small electroplating plants.This could achieve obvious economic and e... 本文以电镀行业废水治理为中心,介绍了国际上一种重要的控制重金属污染的途径——区域集中防治法(CWT),即重金属污染源的区城集中和重金属废水(物)的集中处理。西德、日本以及美国的实践经验和可行性分析表明,这种方法具有明显的经济效益和环境效益,是解决重金属污染的一种很有前途的措施。 文摘来源 In this region, magnetite deposits and minor occurrences are controlled by the magmatic evolution of Carboniferous volcanic-intrusive activity. The in- trusive rocks related to Yamansu deposit are quartz albitophyre, and to Heifengshan and Shaquanzi deposit and Shuangfengshan occurrence are gabbroic diabase, fine-grained quartz diorite and tonalite. The regional concentration of the deposits is controlled by the Aqqikkuduk great profound fracture zone near the boundary between Mid-Tianshan upli... 本区位于北天山华力西地向斜褶皱带东段南缘。磁铁矿床及矿点受石炭纪火山侵入岩控制,其中雅满苏矿床为石英钠长斑岩组合,黑峰山、沙泉子矿床及双峰山矿点为辉长辉绿岩一细粒石英闪长岩一英闪岩组合。中天山隆起与北天山地向斜褶皱带接壤处的阿奇克库都克深大断裂带控制铁矿集中区,可能是火山一侵入岩浆活动的深部通道。容矿空间主要为层间裂隙。围岩为较纯的石灰岩或大理岩,尤其是上盘有中酸性一酸性熔岩、凝灰岩作为遮挡层时,对控制成矿更有利。磁铁矿成矿伴随有强烈的气液渗滤交代作用。虽然磁铁矿成矿看起来与矽卡岩矿床某些方面有相似性,但成矿作用是火山一侵入岩浆活动的继续,而且成矿物质主要是火山侵入岩岩浆期后气液从深部带上来的。因此,把矿床成因划为火山喷发晚期(或喷发期后)与火山侵入岩有关的气液交代一充填类型。 文摘来源 It had been found that vasoactive intestinal pcptide (VIP) could increase cerebral blood flow. The purpose of this study was to investigate the effect of hypoxia on the cerebral concentration of VIP. 32 male adult rabbits were divided into acute hypoxia (simulated altitude 5 000m, 2 hours), hypoxia-adapted (simulated altitude 5 000m, 2 weeks) and sea level control groups randomly. Radioimmunoassay method was employed to determine the regional concentration of VIP in cortex, hypothalamus an... 本实验采用雄性青紫蓝家兔32只,随机分为急性缺氧组(模拟海拔5000m,2h)、低氧适应组(模拟海拔5000m,2周)和对照组。用放射免疫分析法分别测定了海平和模拟缺氧后大脑皮层、下丘脑和海马三个部位血管活性肠肽含量的变化。测定结果表明,急性缺氧组所测三个部位的血管活性肠肽含量较海平对照均有增高,其中下丘脑的含量自对照的12.1±1.1ng/g增至21.1±2.9ng/g(p<0.05),海马的含量自35.7±2.6ng/g增至45.9±1.7ng(p<0.01)。适应组三个部位的血管活性肠肽含量虽略高于对照,但均无统计学意义。这一结果与前人报道的在相应低氧条件下脑血流变化规律是吻合的。因此我们推测血管活性肠肽在缺氧条件下对脑血流的调节可能起重要作用。 文摘来源 << 更多相关文摘
