摘要：
This issue is numerically investigated by schematic model in which the optical scattering and aborption behavior of sphereical nanopaticle is discussed. On the basis of classics effective medium theoretical, the renormalized effective parameters have been introduced. The simulation results are presented by comparisons with effective property models, the screening effect is also discussed in alalyzing the cross-sections in different nanometric size. The phenomena of the shift in resonance frequency by varying the radii of the grain has been shown by the theoretical result.

摘要：
Based on the analysis of accomplishments and trends of modern technologies (such as the computer, wireless communication, creature science, nanotechnology, medical science, et al.), this paper makes a prediction of the future network, and proposes a new concept - the Human Body Network (HBN), which is formed by people around the world whom are equipped with special micro chip in their body. The HBN is the integration and evolution of modern concepts of the Wireless Body Area Network (WBAN), the Wireless Personal Area Network (WPAN) and the Wireless Sensor Network (WSN), and it has abilities in long distance communication. Some key issues such as the structure, protocol, identification code, benefits, and problems waiting to solve are discussed.

摘要：
Based on the rough set theory, this paper consider the contribution of each decision attributes to entire classification through calculate weighted average of its branches, and gather the contribution to avoid local best effect. In this foundation, we can integrate variable precision model and replace approximate precision with variable approximate precision. Then we offer a new concept of variable precision weighted average roughness which was regarded as the criteria for choosing attributes when constructing a decision tree. It improve the accuracy of attribute selection, overcame the impact of noise data effectively and strengthened generalization ability of the decision tree. The algorithm was applied in information management systems of Wuhan City KANG Long Yi-jun health examination centers. Actual data shows that the algorithm offer low complexity and better classification results.
摘要：
In the paper the features and origins of two different gei(给)before VP are presented and discussed.Meanwhile,a diachronic research on their evolution is made,and a typological comparison among dialects is also made to prove the point.

摘要：
In the title compound, [Ir(C10H8N3)(C11H8N)2], the Ir center is octa-hedrally coordinated by the three chelating ligands, with two cyclo-metalated 2-pyridylphenyl ligands [Ir - N = 2.049 (5) and 2.030 (5) Å; Ir - C = 2.016 (6) and 2.012 (6) Å] and a bidentate 2-(phenyl-diazen-yl)pyrrolate ligand [Ir - N = 2.204 (5) and 2.079 (5) Å]. The Ir - N(diazen-yl) bond is longer than the Ir - N(pyrrolate) bond. The structure is stabilized by aromatic π-π stacking, the shortest parallel distance between ring centroids being 3.426 (8) Å..
