The volcanic rocks of the Xiong'er Group occur widely in the southern part of the North China Craton, which mark the beginning of the cover in the southern part of the North China Craton. The age of the volcanic rocks is thus crucial to understand the tectonic regime and evolutionary history of the North China Craton in the Proterozoic age. Zircons from five volcanic rocks and intrusions were dated by U-Pb SHRIMP method. The results indicate that the Xiong'er Group formed in 1.80--1.75 Ga of Paleo-Proterozoic. Since the Xiong'er Group formed earlier than the Changcheng System, the earliest rocks in the Changcheng System is therefore assumed to be formed in 1.75 Ga. A thermal-tectonic event of ca. 1.84 Ga is indicated by new zircon U-Pb SHRIMP ages in the southern part of the North China Craton. The volcanic rocks of the Xiong'er Group thus represent the initial magmatism of the Paleo-Proterozoic breakup of the North China Craton. Numerous inherited zircons in the volcanic rocks mainly formed in ～2.20 Ga, indicating that the source magma of the volcanic rocks may be derived from the ～2.20 Ga crust, or from a mantle magma with significant contamination of the ～2.20 Ga crust.

The granulitic xenoliths discovered in the late Cretaceous basaltic rocks from Tuoyun basin, western Xinjiang Province contain the assemblage of Opx + Cpx + Pl ± Grt ± Qtz ± Kfs. Mineral chemistry, petrochemistry and zircon U-Pb ages from the xenoliths have been reported in the paper. Petrogenesis, the lower crustal nature and the mantle-crust interaction reflected by the granulites are discussed as well. Tuoyun granulites are mainly mafic with few intermediate components, and represent the magmatic products underwent granulite-facies metamorphism in lower crustal condition. Equilibrium temperature and the maximum pressure estimates of the granulites are 910 ± 35℃ and 13.5 × 108 Pa respectively, indicating that the crust beneath southwestern Tianshan had the thickness of less than 44 km and high geotherm (e.g. > 80 mW/m2) when the host magma erupted. During their formation, the fractional crystallization of olivine, pyroxene, plagioclase and ilmenite, plagioclase accumulation and the contamination of felsic components or fluid metasomatism processes had happened. Metamorphic zircon U-Pb age of 253 Ma may record the crust-mantle interaction caused by the orogenic root delamination beneath the southwestern Tianshan.

向前方向性效应是近断层地震动的重要特征之一,使得在垂直于断层方向上表现出明显的速度脉冲分量,引起结构的严重破坏。为考察该类特殊地震动作用下RC框架结构的损伤程度,基于传统的增量动力分析方法,建立考虑材料不确定性和输入地震动不确定性的结构-地震动样本,对一个12层框架结构进行地震易损性研究。利用易损性分析结果计算出结构的破坏状态概率,结合群体结构震害评估中的震害指数经验值,得到多遇地震、设防地震和罕遇地震的易损性指数。研究结果表明:近断层向前方向性地震动作用下,依据我国抗震规范设计的RC框架结构能够满足小震不坏、中震可修、大震不倒的抗震设防目标。尤其在大震作用下,结构仍处于中等破坏水平,表明结构在发生倒塌之前具备充分的富裕度。

地名是随着人类社会的发展,逐渐衍生出的用于标记各种地理实体、行政区域以及居民聚落等的名称,可分为自然地理类地名和人文地理类地名两大类,按照地名的命名渊源,又可以细分为事件地名、人物地名、祈福地名等等。一个城市的地名包含着当地丰富的历史、经济、民俗等诸多文化内涵,是一笔宝贵的财富和重要的文化遗产。然而随着城市化进程的加快,某种程度上对地名演变产生了一些不利的影响,甚者,对集体记忆空间产生了一定的破坏,作为能集中凸显地域特色、展现地域文脉的地名文化,应得到大力传承和保护。可喜的是,文化传承与遗产保护的观念越来越深入人心,各地已陆续深入开展对地名文化的研究、保护与开发利用工作,这对于加强文化建设、弘扬优秀传统文化、树立城市形象、传承城市文脉等都具有十分重要的意义。目前,成都正在积极打造世界旅游目的地,在这个契机下,研究成都地名文化,挖掘成都地名文化价值,将其与旅游挂钩,进行合理的旅游开发与利用,既可以很好的保护成都地名文化遗产,又有助于成都城市形象的树立,还可以为旅游开发提供新的视角,盘活当地旅游业,有着深刻的理论意义和现实意义。成都位于拥有“水旱从人,不知饥谨”美誉的天府之国四川省,历史悠久,人文济盛,是首批国家历史文化名城,在2300多年历史长河的浸润下,形成了特色鲜明、内涵丰富的地名文化,从这些地名中我们可以窥见这个城市所经历的点点滴滴。本文主要采用历史追溯法、地理考察法、语言分析法、文献法和地图法、综合分析比较法等研究方法,梳理成都浩如烟海的地名,剖析其纷繁复杂的地名文化内涵,在此基础上挖掘其价值,充分发挥其旅游功能,探究其用于旅游开发的可能性,提出一系列相应的对策,尽可能的使成都地名文化得到很好的传承、保护与利用。

Objective To investigate the methods of dynamic enhanced multi-slice spiral CT in evaluation of blood flow patterns of solitary pulmonary nodules (SPNs) with enhancement. Methods Seventy-eight patients with SPNs (≤4 cm) with strong enhancement underwent dynamic multi-slice spiral CT (Marconi Mx8000) scan before and after contrast enhancement by injecting contrast material with a rate of 4 mL/s. For the 40 patients in protocol one, one scan was obtained every 2 seconds during 15--45 and 75--105 seconds after injection, while for the 38 patients in protocol two, one scan was obtained every 2 seconds during 11--41 and 71--101 seconds. For all the patients, one scan was obtained every 30 seconds during 2--9 minutes. The section thickness was 2.5 mm for lesions ≤3 cm and 5 mm for lesions >3 cm. Standard algorithm was used in the image reconstruction. Precontrast and postcontrast attenuation on every scan was recorded. The perfusion, peak height, ratio of peak height of the SPN to that of the aorta and mean transit time were calculated. Results The peak height, perfusion, ratio of peak height of the SPN to that of the aorta and mean transit time in malignant SPNs were 34.85 Hu±10.87 Hu, 30.37 ml/(min·100 g)±11.14 ml/(min·100 g), 13.78%± 3.96% , 14.19 s±6.19 s respectively in protocol one, while those in protocol two were 36.62 Hu±10.75 Hu, 30.01 ml/(min·100 g)±8.10 ml/(min·100 g), 14.70 %±4.71%, 13.91 s±4.82 s respectively. No statistically significant differences were found between the peak height (t= 0.673, P=0.503), perfusion (t= 0.152 , P=0.880), ratio of peak height of the SPN to that of the aorta (t= 0.861, P=0.393) and mean transit time (t= 0.199, P=0.843) in malignant SPNs measured in protocol one and those measured in protocol two. All mean transit time in protocol two (36/36) were obtained, but only part of them (25/32) were obtained in protocol one. Conclusion Dynamic enhanced multi-slice spiral CT is a non-invasive method for quantitative evaluation of blood f
