谁把太空敲粉碎 满天星斗落人间——访凉山散记

记得一首歌儿唱得好:"一座座青山紧相连,一朵朵白云绕山间……"哦,凉山,在我的脑海中她是一个神秘而遥远的地方,然而走进她时,跃入眼帘的却是另样的天地、别样的景。这里峰峦重叠,云雾缭绕,湖涌微波,海鸥翱翔,放眼望去,滴翠     

秦汉边郡概念小考

郡在设置之初就与边地有着密切的关系,传世文献中《史记》最早出现"边郡"一词。边郡成为秦汉一个习见的概念,它的认定是要有一定标准的,必须有"障徼"等边防设施才能称为边郡。边郡意涵其实有广义狭义之分,有时并不能严格按"有障徼"的边境线所在来划分界定。边郡与内郡的众多差异中,生产方式的差异有决定性的意义,这些差异影响到人们的习性风气。在中国领土幅员初步成形的时期,秦始皇、汉武帝在位时有过两次大的开边扩土的浪潮,这也是边郡设置的两个高潮,设置过众多的边郡。     

乌尔第三王朝温马地区法庭判案文件译注与简析

乌尔第三王朝时期的法庭判案文件,苏美尔语称为"di-til-la",意为"最终裁决".吉尔苏出土文献最多,在温马也出土了少数泥板,基本上属于财产争诉案件.与吉尔苏的相比,温马的法庭判案文件有自己的特点.本文根据出土于温马地区的20块判案泥板文书,探讨了乌尔第三王朝时期温马地区的民法案例以及涉及的经济和社会制度.     

Study on Low-Frequency Characterizations of Pulse-Type Ground Motions through Multi-Resolution Analysis

This article makes an attempt to investigate the low-frequency characterizations of pulse-type ground motions through ground motion components instead of original records. A decomposed method based on multi-resolution analysis is introduced in this article. The accuracy and validity of the method is tested in frequency domain, time domain and dynamic response. A dataset of 398 low-frequency components is obtained after the decomposition of 91 typical pulse-type records. A probabilistic model to describe the proportion of low-frequency components in corresponding original ground motions is established. At last, the decomposed method is used to investigate the impulsive characterizations of pulse-type ground motions.     

清宫藏成扇鉴赏

扇子,古有＂箑＂、＂翣＂及＂便面＂等称,在我国有着悠久的历史。随着漫长的岁月,扇子历经了不断演变、创新与完善,最终发展成为一个庞大的＂家族＂。扇子有不同的分类法,按形制来分,可分为折叠的折扇及不可折叠的平扇;按材质来分,可分为纨扇（团扇）、竹扇、羽扇、蒲扇、麦秆扇、象牙扇等;按地区来分,可分为川扇、杭扇、潮州扇等。故宫博物院现收藏有成扇类文物近万件,其中绝大部分属于清宫旧藏。清宫成扇品类繁多,囊括了其时成扇的主要品种,这些成扇以折扇和团扇（纨扇）为主,质地有纸、绢、绸、缎、纱、缂丝等,除此之外,

青海地域文化与非物质文化遗产保护

青海从历史上就是个少数民族聚居地,各民族人民在这里创造出了丰富多彩的民族文化,留存下了丰厚的非物质文化遗产。更好地定位与保护好这些有形文化与无形文化,对于发展青海的经济和民族文化具有极其重要的意义。     

Seismic Performance to Emergency Centers,Communication and Hospital Facilities Subjected to Nepal Earthquakes, 2015

Emergency centers, communication systems, and hospitals are essential infrastructures for emergency rescue and subsequent reconstruction activities. An investigation into the Nepal 2015 earthquake sequences found that the visited government offices were functioning normally 40 days after the main shock; that the local media failed to coordinate with the entire society at the beginning, but mobile phone-based communication recovered quickly; and that the hospitals in high-intensity areas were badly damaged as a result of improper design and adverse site configuration. Recommendations are proposed to enhance the aseismic capacity of structural and non-structural components using earthquake early warning and base isolation.
