日本的中京圈和首都圈、关西圈并列被称为具有代表性的三大经济圈。中京圈和首都圈、关西圈相比规模和人口略小,但是以技术密集型工业为主体的产业结构使其在全日本占有举足轻重的地位。战后尤其是以汽车、航空工业为主的运输器械工业得到了空前的发展。进入90年代以来,随着经济全球化和信息化的到来,以重型工业为中心的中京圈迎来了极大的挑战。因此,中京圈在制定产业功能定位、发挥中心区位优势的作用以及基础设施配套建设等方面提出了新的发展规划。2005年在中京圈举行的爱知世博会是21世纪第一个世界博览会。爱知世博会的主题是“自然的睿智”。大会将探讨一些全球性课题的解决方向和可持续发展问题,体现人与自然的和谐。此外,日本也希望通过这些战略性的思考,为中京圈的可持续发展寻找出路。 相似文献

After the 2005 Kashmir earthquake, we mapped surface ground fractures in Tangdhar, Uri, Rajouri and Punch sectors and liquefaction features in Jammu area lying close to the eastern side of the Line of Control (LOC) in Kashmir, India. The NW trending ground fractures occurred largely in the hanging wall zone of the southeastern extension of the causative fault in Tangdhar and Uri sectors. The principal compressive stress deduced from the earthquake induced ground fractures is oriented at N10°, whereas the causative Balakot–Bagh fault strikes 330°. The fault-plane solution indicates primarily SW thrusting of the causative fault with a component of strike–slip motion. The ground fractures reflect pronounced strike–slip together with some tensile component. The Tangdhar area showing left-lateral strike–slip motion lies on the hanging wall, and the Uri region showing right-lateral strike–slip movement is located towards the southeastern extension of the causative fault zone. The shear fractures are related to static stress that was responsible for the failure of causative fault. The tensile fractures with offsets are attributed to combination of both static and dynamic stresses, and the fractures and openings without offsets owe their origin due to dynamic stress. In Punch–Rajouri and Jammu area, which lies on the footwall, the fractures and liquefactions were generated by dynamic stress. The occurrence of liquefaction features in the out board part of the Himalayan range front near Jammu is suggestive of stress transfer 230 km southeast of the epicenter. The Balakot–Bagh Fault (BBF), the Muzaffarabad anticline, the rupture zone of causative fault and the zone of aftershocks — all are aligned in a 25 km wide belt along the NW–SE trending regional Himalayan strike of Kashmir region and lying between the MBT and the Riasi Thrust (Murree Thrust), suggesting a seismogenic zone that may propagate towards the southeast to trigger an earthquake in the eastern part of the Kashmir region. 相似文献

为使用嫦娥一号三线阵光学影像进行月球测图,本文研究月球测图的特殊性问题及其解决方案,提出基于Cle-mentine卫星影像数据和ULCN 2005月球控制网进行月球测图的方法,应用商业数字摄影测量软件和自主研发的辅助软件系统进行了月球测图实验.该实验选择了月球近南极的一块区域(W109.7°~W163.4°,S69.3°~S84.2°,面积约1.5×105km2),采用10个轨道的60景Clementine的UVVIS影像、408个ULCN 2005控制点(其中56个作为检查点)和1 337个连接点,建立该区的DTM和地形图,水平中误差和垂直中误差分别为98.639 m(0.19pixel)和1 003.751 m(1.93pixel).论证基于嫦娥数据生成月球DTM和地形图的可行性. 相似文献

利用欧拉定律和ITRF2005的速度场,给出了全球板块运动模型ITRF2005VEL,并计算了全球地壳旋转总角动量之和。采用离散的Tisserand条件对实测的全球台站运动速度进行约束,建立了一个新的基于NNR参考框架的实测的绝对板块运动模型NNR-ITRF2005,并与地学模型NNR-NUVEL1A和ITRF其他序列建立的NNR模型进行了比较和分析。结果表明,从整体上来看,NNR-ITRF2005比较接近于NNR-NU-VEL1A,但个别板块由于测站较少、分布不均或者测站观测时间短对板块的约束不够等原因,使得这些板块的欧拉极与地学模型的偏差较大。 相似文献
