ABSTRACTGuanhua (official language), Guoyu (national language), and Putonghua (common language) are generally regarded as different names for the same thing in different eras, but from the perspective of cultural history, there are many subtle semantic differences between these three concepts, symbolizing how different social classes and political groups defined their particular experiences, expectations, and efforts to take action. Guoyu, which replaced Guanhua in the late Qing Dynasty, is closely bound up with the construction of modern nationalism. In the 1930s, leftist intellectuals imbued Putonghua with strong proletariat attributes and overtones of indigenous and ethnic equality, wielding it as a tool for critiques against Guoyu. Although Putonghua returned to certain key positions of Guoyu after the mid-1950s, it putatively emphasized the legacy of the leftist language movement, and represented a new political identity. Through these “proper names” for the standard language, it was possible not only to launch a political and social “revolution,” but also to smooth over the historical rifts that this engendered, by repeatedly revising the concepts of “written” and “standard” to form a linear national narrative. 相似文献

Ostrich eggshell (OES) beads are an important kind of human ornaments, because their production reflects the development of modern human behavior, thinking ability, and cognitive level. Although the manufacture procedure of OES beads has been reconstructed in some Later Stone Age sites and early Neolithic sites, little information is known about detailed drilling technologies. In this study, synchrotron radiation micro-CT (SR-μCT) was firstly used to scan OES beads to understand microstructure, drilling marks, and perforation shape in a non-destructive mode. In contrast to other method to research drilling technologies, SR-μCT has a unique advantage that it could eliminate the influence of the adhering soils in a perforation in case that they are not easily removed. The results indicate that (1) SR-μCT could differentiate the eggshell species between Struthio camelus and Struthio anderssoni in terms of pore distribution. Compared to other destructive methods, including the anatomical method, DNA and protein analysis, the species identification through SR-μCT is non-destructive and faster; (2) the outer and inner surface of OES could be non-destructively judged according to OES microstructure, which would help infer the drilling direction; and (3) the perforation shape and drilling marks are distinct between the discontinuous twisting drilling and the multi-rotary drilling methods on the basis of replication experiments. According to these criteria, SR-μCT was applied to examine OES beads found in Locality 12 of the Shuidonggou (SDG) site in China, which were probably discarded in 1.1 k yr BP. The results show that most of ancient beads were firstly drilled from inside. According to the perforation shape and drilling marks, both the twisting drilling and the multi-rotary drilling method with different kinds of drill bits were used in working beads. Therefore, the people in SDG site mastered a few drilling technologies in the early Holocene, and the use of the multi-rotary drilling method reflects the technical development of ancient people. Up to our knowledge, it is the earliest known evidence of the application of the multi-rotary drilling method in China. Furthermore, this study will provide a new approach and important reference to understand drilling technologies of much older OES beads in the Later Stone Age or Upper Paleolithic Age. 相似文献

Echinochloa was an important prehistoric food crop of early agriculture in Asia. Macro-remains can be used to identify Echinochloa. However, when few macro-remains are available, phytolith analysis can be performed. In this study, we examined the phytolith morphology of the glumes, lemmas, and paleas from the inflorescence bracts of nine Echinochloa species from different regions of China and obtained diagnostic, morphological, and morphometric characteristics for Echinochloa. Phytoliths in Echinochloa are different from those in most known crops except those in Setaria italica and Panicum miliaceum. We found the following two diagnostic features within an epidermal silica layer that can be used to distinguish Echinochloa sp. from S. italica and P. miliaceum: (1) the β-type undulated patterns with constricted top of the undulation amplitude and (2) the discriminant functions based on the morphometric data of the β-type undulated patterns, which suggested that 94.9 % of the cross-validated data were correctly classified into Echinochloa, S. italica, and P. miliaceum. Thus, we established the phytolith identification criteria for Echinochloa; this could have important implications in plant taxonomy, archaeobotany, and plant domestication. 相似文献

AUTHOR, N. &; AUTHOR, P. December 2017. Article title. Alcheringa 42, 301-305. ISSN 0311-5518. Dysagrionidae are common in Paleogene sedimentary rocks, but rarely recorded in the Mesozoic. This family, however, is diverse in Burmese amber. A new dysagrionid damselfly, Palaeodysagrion youlini Zheng, Chang &; Chang sp. nov., is described here based on a well-preserved specimen (holotype) in Burmese amber. The new damselfly provides wing apex and body characters for Palaeodysagrion. It differs from Palaeodysagrion cretacia in having Arc slightly distal of Ax2, the midfork slightly basal of the nodus, Cr and Sn almost perpendicular to RA and RP and in having a simple wing system. This is the fourth dysagrionid damselfly described from the Burmese amber.Daran Zheng* [dranzheng@gmail. com], State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, 39 East Beijing Road, Nanjing 210,008, PR China; Su-Chin Chang [suchin@hku. hk]*, Department of Earth Sciences, The University of Hong Kong, Hong Kong Special Administrative Region, PR China; Bo Wang?

The gut contents of ancient humans have been proven to be the most direct evidence for palaeodietary study. In the Xinjiang region of north-west China, large numbers of mummies are well preserved owing to the extremely dry environment to be found there. Fourier-transform infrared spectroscopy (FTIR) combined with multi-archaeobotanical methods, including macrofossil examination, starch grain analysis, phytolith analysis and bran fragments analysis, were applied to investigate the possible gut contents (c.1300 bp by 14C dating) of a person unearthed at tomb 75TAM601 in Astana Cemetery, which were the public graveyards of the ancient Gaochang people (residents of Turpan, dating from about the third to the ninth centuries ce ), in Turpan, Xinjiang. The result of the FTIR analysis showed that the matrix of the possible gut contents consisted of protein and starch and was characterized as undigested food residue. The white mineral fragments of this sample were from the decomposition products of the skeleton. The microfossil analysis demonstrated that Setaria italica, Panicum miliaceum and Triticum aestivum were the main cereal resources for the last meals eaten by the deceased. Moreover, direct macrofossil evidence also advocates for the importance of the three aforementioned cereal crops and fruits of Cucumis melo and Vitis vinifera in the person's diet. 相似文献

Lead isotopic analyses of copper ores in the Early Bronze Age central Hexi Corridor,north-west China
This paper explores the possible provenance of ores employed for metallurgical production during the Early Bronze Age in the central Hexi Corridor of north-west China. In total, 78 pieces of copper (Cu) ore samples were collected from five Early Bronze Age sites and one Cu deposit site (the Beishantang Cu deposit) in the Heihe River region of the central corridor. These sites were dated to the late Machang (4100–4000 bp ), Xichengyi (4000–3700 bp ), Qijia (4000–3600 bp ) and Siba (3700–3400 bp ) cultures. After comparing with published lead (Pb) isotopic data from other possible Cu deposits in north-west China, the results show that the Cu ores collected from the Early Bronze Age sites were most likely derived from the adjacent Beishan Cu deposit. More intriguingly, for the first time in Hexi Corridor, a dozen Cu ores were discovered containing highly radiogenic Pb. Though fundamentally different from those in the Central Plains, they illustrate a possible new type of Cu used in Bronze Age western China, and the first-hand materials are significant for further understanding the provenance of raw metals for metallurgical production in the prehistoric Hexi Corridor. 相似文献
