This paper reports the study of ancient potteries unearthed from the Guangfulin site in Shanghai. From the external features of these potteries, archeologists can classify them into two different cultural types: Liangzhu culture (local culture) and a new culture which might be derived elsewhere, but they can not recognize whether they were produced in the same place. Proton induced X-ray emission (pixe) and instrumental neutron activation analysis (INAA) were used to measure the chemical compositions of the samples and the results were analyzed using multivariate statistics. We found that the two methods can complement each other and their database can be mutually referenced in the study of ancient potteries. Experimental results show that the compositions of the potteries from the two cultural types are different, which means that the materials for ancient potteries of new culture originate from elsewhere. This supports the archaeologists’ speculation that a group of ancient people migrated to Shanghai from some other places 4000 years ago.

Transfer characterization of sulfur from coal-burning emission to plant leaves by pixe and XANES

引用

Chinese Physics C 2009年第11期33卷 1010-1015页

作者：包良满张桂林张元勋李燕林俊刘卫曹清晨赵屹东马陈燕韩勇 Shanghai Institute of Applied Physics Chinese Academy of Sciences Graduate University of Chinese Academy of Sciences Institute of High Energy Physics Chinese Academy of Sciences

The impact of coal-burning emission on sulfur in camphor leaves was investigated using Proton Induced X-ray Emission （pixe） and synchrotron radiation technique X-ray Absorption Near-Edge Structure （XANES） spectroscopy. The pixe results show that the sulfur concentrations in the leaves collected at the polluted site are significantly higher than those in controls. The Sulfur XANES spectra show the presence of organic （disulfides, thiols, thioethers, sulfonates and sulfoxides） and inorganic sulfur （sulfates） in the leaves. The inorganic sulfur in the leaves of camphor tree polluted by coal combustion is 15% more than that of the control site. The results suggest that the long-term coal-burning pollution resulted in an enhanced content of the total sulfur and sulfate in the leaves, and the uptake of sulfur by leaves had exceeded the metabolic requirement of plants and the excess of sulfur was stored as SO4^2-. It can monitor the sulfur pollution in atmosphere.

Study on Shaxi porphyry copper-gold deposit in Anhui:gold mineralization and occurrence determination by pixe

引用

Journal of Central South University of Technology 2003年第4期10卷 352-358页

作者：杨晓勇李勋贵黄德志王奎仁 School of Earth and Space Sciences Jewelery Department College of Geology and Environmental Engineering

Shaxi porphyry Cu-Au deposit was one of the important discoveries of the exploration in the middle-lower reaches of Yangtze River in China in 1970s. Gold occurrence in the Shaxi porphyry copper-gold deposit (central (Anhui) province, eastern China) was investigated by means of microscope analyses, EPMA and pixe. Combined with geological and mineralogical methods, the characteristics of occurrence of gold in the large scale sulfide mineralization in this region were fully investigated. The results show that gold distributes in both chalcopyrite and pyrite as submicroscopic inclusions (less than 1 μm) . Au is positively correlated with As, Fe, S, Cu, Zn and Ti. The condition of gold transformation in thermal fluid system controlling deposition of Au in the region is probably the oxidation potential of the red sedimentary rocks of shale and fine grain sandstone which may be crucial as a geochemical barrier to the reducing fluid. This study lays foundation for the further research and exploration of the porphyry copper-gold deposit both theoretically and practically in the lower reaches of Yangtze region.

以蛇纹石这一中国传统的玉材为对象,旨在通过微量元素含量分析来探索古代蛇纹石玉器原料的可能来源。采用无损的外束质子激发X射线荧光技术(pixe)对来自中国几个典型矿区的蛇纹石样品主量元素和微量元素进行了分析。同时也采用有损的电感耦合等离子体原子发射光谱技术(ICP-AES)对这些蛇纹石样品的微量元素含量进行了比较分析。结果表明,两种分析方法所获取的蛇纹石微量元素含量趋势具有一致性,说明pixe无损分析技术可以应用于蛇纹石的微量元素分析研究。讨论了蛇纹石的微量元素含量与地质成因之间的关系,这些蛇纹石的微量元素含量存在明显的差异,这种差异可以用来区分不同地质成因的蛇纹石。Ⅰ型地质成因的蛇纹石中微量元素中Ni含量较低,且几乎不含Cr和Co,而Ⅱ型地质成因的蛇纹石中则含有较高微量元素的Cr,Co和Ni。采用pixe技术分析了来自浙江、江苏、河南、安徽和湖北等省出土的新石器时代至战国时期(4585BC—221BC)14个遗址或墓葬出土的18件蛇纹石玉器的化学成分,通过与两种地质成因类型蛇纹石的微量元素比较分析,初步推测了这些蛇纹石玉器原料的可能来源。以蛇纹石微量元素含量与地质成因类型之间的关系来探索古代蛇纹石玉器玉料可能的来源是一种有益的尝试。

pixe ANALYSIS OF GRAPHITE PHASE IN NODULAR CAST IRON

Nuclear Science and Techniques 1992年第3期3卷 210-215页

作者：钟溟冯松林王禹任闽秦刘年庆张晓峰焉伶娜韩其勇 Institute of High Energy Physics Academia Sinica Beijing 100080 China Beijing University of Science and Technology Beijing 100083 China

The graphite phase has been extracted from the nodular cast iron to measure the concentration of trace element in it. The impurity phase was removed from the extracted matter by dissolving it with HCl and HCl+H2O2 to get the pure graphite phase. pixe measurements were performed with thick targets of the pure graphite phase. Differences in the trace element concentrations between the graphite phase and the matrix have been observed. The effect of Ti and As in graphite phase on the nodularization rate and the mechanical properties have been studied.

作者：邬显慷曾先周杨福家 InstituteofNuclearResearch theChineseAcademyofSciencesShanghai201800China

The study of paper damage under bombardments of protons and X--rays is reported. An on--demand beam pulsing system is useful for the pixe analysis of delicate objectS. IXX (or pixe--induced XRF) is more suitable than pixe in terms of damage to the sample. Some new pixe and IXX applications of archaeological paper--like samples in recent years are given.
