试论清代皇帝明黄色朝袍的功用   总被引:2,自引:0,他引:2  
在清代皇帝冠服中,明黄色朝袍的功用尤其引人关注。但是,长期以来人们对“朝祭所御”的概念往往含混不清,以至认为清帝明黄色朝袍既可亲郊飨庙又能御殿朝贺,模糊了朝服与祭服的区别。顺治十年(1653年)都察院左副都御史傅景星奏言:“自古帝王一代之兴,必有一代之制,黄帝尧舜垂衣裳而天下治。衮冕黼黻代有不同,朝有朝服,祭有祭服,所以肃臣民而格上下也……”。本文旨在讨论清帝明黄色朝袍的不同作用,从而区分出朝服与祭服的不同。  相似文献

A small pit in the articular surfaces of the third tarsometatarsal joint has been noted with particularly high frequency in North American Indians. This pit varies in depth, and covers most of the inferior third of the articular surfaces of the third metatarsal and the lateral cuneiform; it is accompanied by remodelling of the inferior surfaces of the bones involved. In the present study, patterns of occurrence are examined in a prehistoric skeletal population from west-central Illinois. This population is extremely well preserved, enabling a thorough examination of feet as well as hands for most individuals. The sample included 496 adults and juveniles above the age of 6 years. Of this total population, 18 per cent exhibit the variation, which occurs more frequently in females and is unrelated to size. Furthermore, 29 per cent of the individuals in which it occurs exhibit this variant only unilaterally, with no significant side differences. Various lesions, trauma and acquired or activity-related aetiologies are explored, as are the patterns of sex association, occurrence near an area of ligamentous attachment and lack of age and size association. It is hypothesized that a discrete genetic trait is represented in the third tarsometatarsal joint of this population in the form of an anomalous interosseous plantar ligament. © 1997 by John Wiley & Sons, Ltd.

ABSTRACT

The employment of timber pegs in timber structure joints is a widespread technology in the field of timber frame building in the United States, where the Timber Frame Engineering Council has published a special Standard to supplement the National Design Specification for Wood Construction. The authors have been studying the possibility of supplementing the Eurocode 5 design formulas, thought for timber joints with metal connectors, with specifications needed for a reliable design when employing timber pegs. The field of application envisaged is that of restoring timber structures and results obtained until now are quite encouraging. In this step of the research, more attention has been paid to deformation process: fir and chestnut samples have been tested to determine their dowel-bearing behavior with steel and ash timber peg while double-shear plane joints made of the same wood species, and fastened with steel as well as timber pegs, have been analyzed.  相似文献

历史时期射阳湖演变模式研究   总被引:2,自引:0,他引:2  
射阳湖历史上曾是江苏境内著名的大湖。历史时期,湖区经历了浅水海湾—古泻湖—淡水湖泊—沼泽性湖泊—平原沼泽的演变模式。春秋以前,本区是里下河浅水海湾的一部分;春秋至唐代,本区由古泻湖逐步演变为淡水湖;南宋以来,1128年黄河夺淮以后,大量泥沙进入本区,湖区淤积迅速,成为沼泽性湖泊,加之人类开发活动的深刻影响,射阳湖逐渐演变为里下河平原的一部分。  相似文献

抗美援朝运动期间,南京市医药卫生界组建医疗团奔赴前线。为保证顺利完成各项任务,医疗团在组织宣传、任务分配、经费筹措、人员轮换及家属安抚等方面均做了有效安排。服务期间,医疗团在救治伤病员、建立血库、营地防疫及帮助野战医院建章立制、改进设施、培训人才等正规化建设方面贡献突出。通过前线实践锻炼,医疗团团员提高了医疗技术水平和思想政治觉悟,多数成为优秀业务骨干,推动了南京市卫生事业的发展,但仓促组织医疗团也曾给南京市的医疗卫生工作在短期内带来一些问题。  相似文献

1956年,全行业公私合营后不久,鉴于建立统一的政治体制及与计划经济体制相适应的新工资制度的需要,国家开始在新公私合营企业中实行工资改革。上海新合营企业的工资改革与全国各地一样正式开始于1956年9月,但由于情况复杂,历经准备试点及全面推开等阶段,直到1957年10月才基本结束。其中工资改革的集中统一领导,工资水平与工资增长指标,新工资等级,变相工资、计件工资、保留工资等问题成为工资改革中最重要的内容。新合营企业工资改革的完成,标志着与计划经济体制相适应的统一的企业工资制度开始全面确立,在收入分配环节上,基本完成了对新合营企业从产权到治理结构、再到分配制度的崭新的企业制度安排。  相似文献

Dislocation is the most severe form of developmental dysplasia of the hip (DDH). It significantly impairs hip function in the young, and may lead to debilitating early‐onset osteoarthritis in adults. To our knowledge no thorough study of a large skeletal population has ever been undertaken to determine the wide range of diagnostic criteria for this condition in pathological specimens. To identify these criteria we have analysed the cases of developmental dislocation from a large series of 6000 individuals (6580 hips) from the medieval cemetery at Spitalfields in London, UK. We describe the changes at the true acetabulum, and have created a four‐stage classification of the false acetabulum. The skeletal response to the altered biomechanics and limb shortening that occurs in developmental dislocation is described in the pelvis, lower limb and spine. This includes asymmetric growth in childhood, and asymmetric degenerative change in adulthood. We conclude with a discussion of the clinical literature on developmental dislocation of the hip that will aid palaeopathologists to estimate the symptoms that an excavated individual may have experienced during their lifetime.

This study examines possible morphological variation in the knee joint of Homo sapiens with increasing age in ostensively healthy and non‐pathological distal femora and proximal tibiae. Throughout the lifetime of each individual, the hard tissue of the knee undergoes considerable remodelling as a response to biomechanical stresses, changes in bone microarchitecture and reduction of bone mineral content as a concomitant of ageing. The knee is also subject to greater levels of degenerative joint disease than any other joint. If death occurs whilst such diseases are in the earliest stages, initial bone changes may not be visually obvious in museum specimens. If such specimens are used for comparative analyses, it is hypothesised that changes might render it problematic if all ages are conglomerated into discrete samples. This study therefore investigates the degree to which the distal femur and proximal tibia change shape during ageing and, if changes are present, whether they are expressed similarly in males and females. It also examines whether changes are of greater magnitude than those morphological differences which might exist between populations. In an example population of African‐Americans, results indicate that there is a statistically significant difference in shape between age groups and those differences become progressively greater between the youngest and oldest adults. Results also show that although morphological variation caused by ageing is apparent, those shape differences attributable to sexual dimorphism are more powerful. When two additional populations are analysed jointly with the African‐Americans (Caucasian Americans and the European Spitalfields sample), results indicate that inter‐population shape differences are considerably greater than differences caused by increasing age. Results imply that it is justifiable to combine specimens of all ages into discrete samples for comparative purposes. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献
