Nearly 200000 animal skeletons are unearthed in the Unit T0202 from Zhongba Site of Zhongxian *** to the analysis of 129165 specimens,these skeletons may be classified into 5 kinds, namely,Mammalia,Osteichthys,Aves,Amphibian and Reptilia,which belong to 13 orders,28 families and 42 *** this paper,based on archeological dating and AMS 14 C data,through statistically analyzing the unearthed skeletons and studying the change of the smallest individual numbers,these research results detected the following:1)In almost all the time of 2370―200 BC,in Zhongba region, some animals distributed widely,such as Muntiacus sp,Elaphodus cephalophus and Muntiacus sp. inhabiting in glade and grassland,Scrofa *** Canis familiaris raised by the ancient people,rodentia rabbit and Rattus rattus,which suggested that a fairly good ecological environment of forest and grassland was preserved at that period and the predecessors began to raise domestic animals from 1750 to 1000 BC,which has lasted until today.2)Rhinoceros only lived during 2000―1750 BC,1000― 700 BC and 700―500 BC,which indicates that the ecological environment of grassland and wetland might be better in these phases.3)Macaca *** Ursus arctos appeared only after 1750―1000 BC, which may show that the forest condition is better for animals to live during 1750―200 BC.4)The smallest individual numbers of Bublus sp.,bos *** otters emerged during about 2370―1750 BC, which perhaps infers that water area during the early period was wider than that of the late period.5) Since skeletons of rhinoceros are discovered in strata of Zhongba Site during 2000―1750 BC and 1000―500 BC,according to the climate and ecology environment which rhinoceros live in now,the average annual temperature and precipitation during 2000―1750 BC and 1000―500 BC are supposed to be probably higher than that of *** Zhu Kezhen considered that the first low temperature period in the past 5000 years of china was between 1100 BC a

龙垭旧石器遗址位于四川省简阳市沱江二级支流康家河左岸,2010年7~9月,四川省文物考古研究院等单位对该遗址进行了抢救性发掘,清理面积87 m^(2),出土石制品559件,动物骨骼化石数千件。石制品原料多选用砾石,岩性以石英岩为主,其次有硅化木、石英等。石制品类型主要有石核、石片、断块及手镐、大型石刀、似手斧、重型刮削器、砍砸器、刮削器、尖状器、凹缺器和石球等石器,并有三组可拼合标本。从石制品面貌上看,古人类能够剥取大石片、以之加工石器,两面器技术不典型,初步呈现出似阿舍利技术特征。光释光测年显示,遗址年代可能达到旧石器时代中期。这批材料为研究四川盆地中部丘陵地区沱江流域更新世人类生存、生产提供了重要资料。

川渝地区分布有8000余处石窟和摩崖造像,大部分凿刻在砂岩中,长期环境作用导致砂岩性能出现劣化现象,对赋存文化遗产的安全造成了不同程度的威胁。为了提升传统修复材料的性能,使用玄武岩纤维(BF)和聚乙烯醇纤维(PVAF)替代传统修复材料中的麻刀,研究纤维种类和掺量对修复材料性能的影响规律。结果表明:掺加BF、PVAF能够提高修复材料的抗折强度、劈裂抗拉强度和体积稳定性,而对抗压强度和固化反应产物影响较小;当BF、PVAF掺量较高时,纤维的分散效果较差,产生的摩擦阻力随之减少;相同掺量下,BF的增强效果比PVAF更为显著。
