Overview of Preventive Conservation Research Work on Seismic Mitigation and Subway Vibration Control in Chengdu Museum of China

ABSTRACT

The 2008 Wenchuan earthquake brought numerous issues to the attention of researchers of seismic mitigation in Chinese museums. After the Wenchuan earthquake, the structural design team of Chengdu Museum conducted a series of research projects on seismic mitigation and subway vibration control design of buildings. These projects included the following topics: optimization of design, numerical simulation of seismic performance, analysis of key technologies for the base isolation structure, in-depth studies on structural vibrations caused by the nearby subway, and proposals for reducing structural vibrations. In 2015, after the superstructure of Chengdu Museum was completed, conservators evaluated the safety of permanent exhibitions under earthquake conditions. Seismic protection devices were installed on the showcases according to the preventive conservation requirements for museum collections. Reinforced measures were used for museum collections according to the methods suggested in the document ‘Specification for seismic protection of museum collection’ (WW/T 0069-2015). The conservators also built a systematic platform for earthquake monitoring for museum collections. Preventive conservation studies on seismic protection and subway vibration control in Chengdu Museum are summarized and forecasted.     

构建编辑人的和谐世界

中国人民大学公共管理组织与人力资源研究所会同新浪新闻频道联合文施了"2006年中国上班族工作和谐指数调查",共有近4000名存职人员通过网络接受了调查.调查结果让人惊讶,近七成的上班族郜感到工作不和谐.     

羌族宰相谢方叔

谢方叔,南宋末大臣,威州(今四川理县东北)人。嘉定十六年进士。那时,正是大宋国日渐衰微,亡国的征兆已日渐显现出来。谢方叔就是在这样的大背影下走上了历史舞台。1251年,宋理宗授予谢方叔"知枢密院事兼参政知事"辅佐赵昀掌管军事机密、边防事务,与宰相同议朝政。接着宋理宗拜谢方叔为左宰相,同时授予枢密院最高长官——枢密使一职,担起了负责大宋军国大事的重任。谢方叔上任后一方面关心庶民百姓,另一方面不断与宦官、内侍作斗争,但最后以彻底失败而告结束,以自己坎坷的一生陪伴南宋王朝走完了最艰难困苦的岁月。     

洪秀全妇女思想之"耶儒合流"——以"一言两书"为例

《劝世良言》、《钦定旧遗诏圣书》和《钦定前遗诏圣书》对洪秀全思想影响巨大,洪秀全"男女平等"思想、禁止奸淫妇女和反对淫乱思想、"为妇之道"思想、多妻制思想、对待女奴婢的思想以及妇女贞节观皆同这三本书有着直接的渊源关系,它们是洪秀全"耶儒合流"思想的主要来源.但从实质上看,洪秀全的妇女观仍然是中国传统的封建伦理道德观,而且在西方上帝的宗教招牌下有过之而无不及.洪秀全不可能具有男女平等的思想.     

Genetic analysis of fruit shape traits at different maturation stages in sponge gourd

The fruit shape is important quantitative trait closely related to the fruit quality. However, the genetic model of fruit shapes has not been proposed. Therefore, in the present study, analysis of genetic effects for fruit shape traits （fruit length and fruit perimeter） in sponge gourd was conducted by employing a developmental genetic model including fruit direct effects and maternal effects. Analysis approaches of unconditional and conditional variances were applied to evaluate the genetic behavior of fruit shape traits at economical and physiological maturation times. The results of variance analysis indicated that fruit length and fruit perimeter were simultaneously affected by fruit direct genetic effects and maternal effects. Fruit direct genetic effects were relatively more important for fruit shape traits at whole developmental period. The gene expression was most active at the economical maturation stage （1-12 d after flowering） for two shape traits, and the activation of gene was mostly due to direct dominance effects at physiological maturation stage （13-60 datter flowering）. The coefficients due to different genetic effects, as well as the phenotypic correlation coefficients, varied significantly between fruit shape traits themselves at various maturation stages. The results showed that it was relatively easy to improve fruit shape traits for industrial purpose by carefully selecting the parents at economical maturation stage instead of that at physiological maturation stage.     

《四库全书》馆的机构与运作——以《四库全书》职名表为中心的考察

目前通行的浙本职名表与殿本职名表有较大的不同,这是由于两表的编排原则不一造成的。以殿本职名表为主,通过浙本职名表与殿本职名表的比较、参证、互补,更能全面真实地反映四库馆的机构与运作情况。四库馆的机构分为两大系统:其一为翰林院系统,专司《四库全书》的校阅与编修;其二为武英殿系统,专司《四库全书》的缮写、校对与装印。两者互不统属,但又互相配合,统归于总裁官掌控。四库馆中各馆职分工清晰,统属明确,环环相扣,构成一个有机的整体,有利于四库馆的良性运作,保证《四库全书》编修的顺利完成。     

生物化学综合性实验的探索与评价

以河北科技师范学院2005级生物科学、生物技术专业学生为样本,通过对生物化学综合性实验效果的调查,说明综合性实验在突出学生主体地位、激发学生兴趣等方面起到了积极的作用,能够在培养学生团队合作精神、科研能力等多方面综合能力的提升。     

文科综合实验教学示范中心建设的基本经验——基于协同理论的思考

文科综合实验教学示范中心的建设,是我国高等学校文科实验教学改革创新的重要成果。基于协同理论,对文科综合实验教学示范中心的孕育过程、决定因素和发展动力3个方面进行了深入思考,并总结了文科综合实验教学示范中心的建设经验。     

文科实验教学的探索

河北大学以推进文科综合实验教学中心建设为契机,坚持以人为本,以培养实践能力和创新能力人才为目标,从多个方面推动实验教学改革。中心加强了通识教育实验,完善了专业实验教学体系,开设了实战型实验和创业型实验,并以研究性实验和开放性实验以及各种大赛作为实验教学的补充。     

反美主义与韩国外交政策

反美主义目前已成为国际关系中的重要现象。韩国的反美主义已经成为影响韩国政治与外交的重要因素。其实质是一种反美情绪而非根深蒂固的意识形态敌对,源自韩国经济发展的促进、民主化的推动、民族主义的膨胀与美韩不平等关系的刺激。通过利益表达机制与媒体报道,韩国反美主义的社会影响与政治效应愈加明显。对美韩同盟、美韩关系、朝鲜半岛问题以及东北亚格局都有所影响。成为研究韩国外交政策不可或缺的元素。
