特别是CSP?技术的引进,热轧带钢市场在生产技术和产品范围经历了连续的改变,这明显地反映在25套CSP?生产线中的42台CSP?连铸机上.在过去15年中,发展的焦点--CSP?连铸技术是提高产量和产品质量的一个关键因素.需要提到的开发步骤是连续开发结晶器的几何形状和浸入式水口的设计,电磁制动影响钢水的流动特性,振动装置和新的振动曲线,铸坯导向和板坯的几何尺寸及二冷水的改进.所有的这些开发都是为了生产高表面质量的板坯.为了完全满足极高的表面质量,一种革新式的除鳞装置布置在连铸机后部.在TKAST获得的初步结果显示对质量有正面的影响.上述提到的开发为生产钢种范围的扩大提供了坚实的基础.特别是高碳和裂纹敏感钢种及内部质量要求苛刻的钢种,今天都可以通过CSP?浇注工艺可靠地生产.

Background: The global decrease in wildlife populations, especially birds, is mainly due to land use change and increasing intensity of land use(Parmesan and Yohe 2003). However, impacts of management tools to mitigate biodiversity loss at regional and global scales are less apparent in forest regions that have a constant forest area,and which did not suffer from habitat degradation, and where forests are sustainably managed, such as in Central Europe or the northeastern USA. A biodiversity assessment for Germany suggested, for example, that bird populations were constant(Bundesamt für Naturschutz 2015).Results: This study shows that changes in the environment and in forest management over the past 45 years have had a significant, positive effect on the abundance of non-migratory forest bird species in Central Europe. Economy(timber prices and GDP), forest management(timber harvest and mixed forest area), and environmental factors(atmospheric CO_2 concentration and nitrogen deposition) were investigated together with changes in abundances of migratory and non-migratory forest birds using partial least squares path modeling. Climate change, resulting in longer seasons and milder winters, and forest management, promoting tree diversity, were significantly positively related to the abundance of non-migratory forest birds and explained 92% of the variation in their abundance in Europe. Regionally-migrating forest birds had stable populations with large variation, while birds migrating across continents declined in recent decades, suggesting significant, contrasting changes in bird populations in Europe. In northeastern North America we also found evidence that non-migratory forests have experienced long-term increases in abundance, and this increase was related to management. The increase of populations of nonmigratory forest birds in Europe and North America is associated with an increase in structural diversity and disturbances at the landscape ***: Our

＜正＞ MR Tomography has entered clinical practice in the early 1980s with the introduction of the first commercial scanners. In its twenty years of history it went through several developmental cycles. Development and progress today is as steep and rapid as ever, as illustrated by the record participation of the recent meeting of the International Society of Magnetic Resonance in Medicine in Glasgow. MR instrumentation is going through a rapid change affecting all components of a MR-system:

摘要背景:随着功能磁共振成像(fMRI)的引入,其无损伤性的研究手段,为古老针刺方法的研究带来了新的前景,人们从大脑的不同功能着手,尝试着用fMRI来解开经络穴位与大脑的相关性。目的:通过fMRI观察针刺光明、太冲穴位时,大脑不同区域的相关反应。设计:以医学院的健康自愿参加实验的学生为研究对象,随机对照的验证性研究。单位:一所中医药大学医院的针灸科,一所中医药大学的基础医学院及德国弗莱堡大学医学院放射医疗中心。对象:实验于1997-06在德国弗莱堡大学医学院放射医疗中心进行,健康志愿者19例,皆为医学院学生。男4例,女15例。受试者均自愿参加,无针刺经历,无神经及精神病史。按随机对照原则分为视觉刺激加针刺单侧组7例,男2例,女5例。视觉刺激加针刺双侧组6例,男1例,女5例。单纯针刺双侧组6例,男1例,女5例。方法:用fMRI对不同条件的各组学生在针刺光明、太冲穴时,视觉皮质区与相关脑区的反映以及是否诱导其功能进行了观察。针刺用无菌无磁性的不锈钢针(直径为0.25mm,长约30mm,华佗牌,苏州医疗器械公司生产),每穴操作完后,询问其得气情况。针刺的所有例数统一由有多年工作经验的针灸医师完成。主要观察指标:大脑皮质的血氧饱和水平(BOLD)的变化,幅度,响应延迟,时间波动。
