徐州市表层土壤中金属、S、Br等元素与磁学参数的多元统计解析

系统采集了徐州表层土壤样品21件,测定了土壤中Al,Fe,Ti,Ag,Se,Sc,Ga,Ba,Li,Bi,V,Pb,Cu,Zn,Cd,Ni,Co,Cr,As,Hg,Sb,Mn,Mo,Be,Sn,Br,S,Pt,Au,Pd等元素含量,以及χ,χfd,χARM,SIRM,SOFT5个磁学参数的数值。利用多元统计的方法对30种元素和5个磁学参数进行了因子分析、聚类分析和典范相关分析。结果表明,磁学参数χ,χARM,SIRM,SOFT所表征的磁性矿物与表层土壤中Ag,Se,Sc,Pb,Cu,Zn,Mo,Pt等元素具有内在联系,这些磁学参数有可能作为这些元素的代用指标;χfd所表征的磁性矿物与来自土壤母质的元素Al,Ti,Ga,Li,V,Mn,Be,Au等显著相关,而Bi,Co,Cr,As,Hg,Sb,Pd等则与土壤中的磁性矿物没有联系。典范相关分析表明,表层土壤中磁性矿物主要来自交通运输和煤炭燃烧。     

圈养大熊猫血清中无机元素的研究

Pseudo-dipole signal removal from WMAP data

We have discovered in our previous work that different observational systematics, e.g. errors from antenna pointing directions or an asynchronism between the attitude and science data may generate a pseudo-dipole signal in the full-sky maps of the cosmic microwave background (CMB) anisotropy that have been published by the Wilkinson Microwave Anisotropy Probe (WMAP) team. We have found that the antenna sidelobe response to the Doppler signal produces a similar effect. In this work, independent from the sources, we have uniformly modeled the pseudo-dipole signal and have removed it from the published WMAP7 CMB maps by model fitting. The result demonstrates that the released WMAP CMB quadrupole is almost completely artificial.

Mapping-Based 3D Hexahedral Finite Element Mesh Generation Method

Mapping mesh generation is widely applied in pre-processes of Finite Element Method （FEM）. In this study, the basic 3D mapping equations by Lagrange interpolating function are founded. Based these equations, a mapping pattern library, which maps essential configurations e.g. line, circle, rotary body, sphere etc. to hexahedral FEM mesh, has been built. Then available FEM mesh will be generated by clipping and assembling the mapped essential objects. Study case illustrates that the proposed method is simple and efficient to generate valid FEM mesh for complex 3D engineering structure.

Use of a multi-temporal grid method to analyze changes in glacier coverage in the Tibetan Plateau

This paper describes a multi-temporal grid method for quantifying changes in glacier coverage. A multi-temporal grid synthesizes spatial, attribute and process components of glacier information by sequentially combining spatial data from satellite images or maps. It enables us to identify glacier retreat and advance areas in individual grid cells for three or more periods of data sets. Discrepancies among the sequential data sets were detected graphically and numerically, including noise from geo-location error, misclassification, or different interpretation results in various pixel resolutions. Noise was detected and corrected to a large extent by visualization of the synthetic grid. The paper compares the results with that from a common method based on individual data sets, focusing on the Mt. Naimona'Nyi and Mt. Qomolangma regions at the northern slopes of the Himalayas. Results show that the identified noise (e.g. by 2.5 km2 in the Mt. Naimona'Nyi region) is much larger than measurement uncertainty calculated by sensor resolution and co-registration error (e.g. by 0.015 km2 in the Mt. Naimona'Nyi region). After noise removal, we notice that glacier recession clearly accelerates. The multi-temporal grid method results in a better quantification of glacier variation. It shows that glaciers in the Himalayas have both retreated and advanced during the last several decades, with retreat dominating and accelerating. Glaciers on the northern slope of Mt. Qomolangma in the middle Himalayas retreat more extensively and faster than those in the Mt. Naimona'Nyi region in the western Himalayas.
