金沙遗址出土青铜器的初步研究

金沙遗址出土青铜器1200余件,初步观察,金沙铜器的铸造工艺技术沿袭三星堆时期的传统技法;在装饰技法上主要有墨绘、穿孔、立体装饰、铸纹、镶嵌等。从金沙青铜器材质分析,其青铜矿产地具多源性。从金沙青铜器的文化内涵来看,其与三星堆文化之间有不可分割的延续性。     

An Early Permian brachiopod fauna of Gondwanan affinity from the Baoshan block,western Yunnan,China

The present paper describes and illustrates an Early Permian brachiopod fauna collected from two localities from the upper part of the type Dingjiazhai Formation near Youwang, 30 km south of Baoshan in the Baoshan block, western Yunnan, China. The brachiopod fauna is dominated by Stenoscisma sp. and Elivina yunnanensis sp. nov. and exhibits strong generic and some specific links with faunas from the Bisnain assemblage of Timor and the Callytharra Formation of Western Australia and, to a lesser extent, faunas from the Jilong Formation of southern Tibet, the Tashkazyk Formation of southeastern Pamir, the lower Toinlungkongba Formation of northwestern Tibet, the upper Pondo Group of central Tibet, and the Jimba Jimba Calcarenite of the Carnarvon Basin, Western Australia. Based on these correlations, a Late Sakmarian (Sterlitamakian) age is preferred for the Dingjiazhai brachiopod fauna. Two new species are proposed: Globiella youwangensis sp. nov. and Elivina yunnanensis sp. nov.

SPACE–TIME MEASURES OF DEMAND FOR SERVICE: BRIDGING LOCATION MODELLING AND ACCESSIBILITY STUDIES THROUGH A TIME‐GEOGRAPHIC FRAMEWORK

Demand for service in location modelling is often evaluated based on the spatial proximity of fixed and static reference locations of demand (e.g. home) to a facility, which ignores person‐specific activity–travel patterns and the temporal changes in demand for service throughout the day. To address these limitations, this study draws upon recent developments in space–time measures of individual accessibility to explore the spatial and temporal structures of demand by considering individuals' space–time constraints and impact of existing urban structures. Based on a time‐geographic framework, eight space–time demand measures were developed and compared with three conventional location‐based demand measures for 12 hospitals through an empirical study conducted in Columbus, Ohio. The results show that geographic proximity between clients' home and facilities may not be an effective indicator for service demand, and conventional demand measures tend to underestimate potential demand for service in most situations. The study concludes that space–time demand measures that take into account people's activity‐travel patterns in space–time would lead to better estimation of demand for service in most cases.     

典型环氧类粘结材料老化过程的探索性研究

环氧树脂类粘结材料目前已成为文物保护工作中常用的粘结材料。但是,在一些应用案例中经常发现环氧树脂类粘结材料有变色、脆化、剥落等老化现象。为了了解环氧类粘结材料的老化规律,摸清材料成分、配方和环境因素的影响,以通用双酚A型环氧树脂为主剂与各种典型固化剂、稀释剂、偶联剂等配制成黏结材料,模拟自然界极端环境条件,通过反复的破坏循环实验,探讨典型环氧类粘结材料的老化过程和机理。     

Isotopic Reconstruction of the Late Longshan Period (ca. 4200–3900 BP) Dietary Complexity before the Onset of State‐Level Societies at the Wadian Site in the Ying River Valley,Central Plains,China

During the late Longshan period (ca. 4200–3900 BP) settlements on the Central Plains of China underwent a diversification in food production technologies, which set the stage for rapid economic and social development. The introduction of novel domesticates such as rice, wheat, cattle, and sheep not only provided more food choices, but also changed ideas concerning land use, farming techniques, and the use and mobilization of large scale labor forces. To better understand the contribution that these new dietary items and practices made to shaping the late Longshan period societies, a stable isotope ratio study of humans (n = 12) and animals (n = 42) was conducted at the late Longshan period site of Wadian. The human δ¹³C and δ¹⁵N values are clustered into two distinct groups. One group of nine individuals (δ¹³C = −9.9 ± 0.7‰; δ¹⁵N = 7.5 ± 0.5‰) had a predominately C₄ diet based on millet grains with little protein input from the domestic animals. The other group of three individuals (δ¹³C = −14.3 ± 0.8‰; δ¹⁵N = 10.2 ± 0.3‰) had a mixed C₃/C₄ diet of millets and rice and were consuming sheep and cattle. The animals also displayed dietary diversity with the pigs (δ¹³C = −11.3 ± 2.5‰; δ¹⁵N = 6.9 ± 1.0‰, n = 10) and dogs (δ¹³C = −10.1 ± 1.0‰; δ¹⁵N = 7.2 ± 1.1‰, n = 7) having mostly a C₄ plant based diet (millets). In contrast, the cattle (δ¹³C = −12.8 ± 2.1‰; δ¹⁵N = 7.6 ± 0.7‰, n = 9), sheep (δ¹³C = −16.7 ± 0.9‰; δ¹⁵N = 7.6 ± 0.1‰, n = 2), and cervids (δ¹³C = −20.8 ± 0.9‰; δ¹⁵N = 5.0 ± 1.2‰, n = 10) had diets with a greater contribution from C₃ sources such as rice and wild plants. The discovery that humans and animals had different subsistence patterns indicates dietary complexity at Wadian and that rice agriculture, and cattle and sheep husbandry practices were already an important part of the local economy by the late Longshan period in the southern region of the Central Plains of China.

河南禹州瓦店遗址出土植物遗存分析

《河南禹州瓦店遗址出土植物遗存分析》是一篇浮选报告。浮选法是通过考古发掘获取古代植物遗存的最为有效的手段。通过在瓦店遗址开展的浮选工作,获得了丰富的属于龙山时代的炭化植物遗存,其中包括了粟、黍、水稻、小麦和大豆五种农作物。通过量化分析发现,在出土的农作物品种中,粟和水稻的出土概率几乎相当,这说明,北方旱作农业的代表作物～粟和南方稻作农业的代表作物～水稻,在瓦店遗址的龙山时代的农业生产中是同等重要的。文章从文化因素和环境背景两个方面对这一现象进行了分析,认为文化因素可能起到了更大的作用。瓦店浮选结果中发现了原产于西亚的小麦,说明至迟在距今4500年前后小麦已经传入中原的腹心地区。
