Chinese Quarterly Journal of Mathematics 2012年第3期27卷 364-370页

作者： PIA o Yong-jie SHI Rcn-shu Department of Mathematics Yanbian University Yanji 133002 China

We introduce the concept of a weakly G-quasiconvex map with respect to a map on generalized convex spaces and use the concept to prove coincidence point theorems and almost-like coincidence point theorems. As applications of the above results, we derive almost fixed point theorems and fixed point theorem. These main results generalize and improve some known results in the literature.

小麦生育期组织果糖分布(英文)

作物学报 2000年第5期26卷 549-556页

Tissue fructan content of vegetative parts was examined in four wheat genotypes to determine genotypic differences and distribution and accumulation patterns throughout growing season. Effects indicated that significant genotypic differences were established for tissue fructan content of stem, chaff, leaf, peduncle and total plant throughout growing season and grain protein content and grain yield. Total plant fructan content accumulated to a peak at about milk stage, and then rapidly declined until maturity, coinciding with the period of rapid grain filling. The two high protein genotypes, Cunningham and PST90 19, had lower tissue fructan content in the stem and the total plant than their low protein lower case counterparts, SUN109A and TM56, at most sampling dates. Among plant parts, stem was the most important tissue for fructan reserve and the greatest contributor to grain filling. Tissue fructan content was negatively correlated with grain protein content between heading and maturity, but not correlated with grain yield.

Materials with a high on-off resistance ratio could become the basis for resistive random-access memory (RRAM). It is assumed that one of RRAM types can be based on hybrid organic-inorganic systems, while particular attention is focused on hybrid systems consisting of metal nanoparticles (NP) embedded in organic matrix (oM). In this investigation we created and studied the hybrid organic-inorganic systems made of metal (Ag) nanoparticles embedded in organic semiconductor material CuPc. The LEED patterns and NEXAFS data demonstrate that the CuPc films deposited on Au(001) substrate are highly ordered and molecular planes lie parallel to the gold surface. The metal atoms were deposited on the outer surface of the organic molecular film and self-assembled into nanoparticles due to surface and bulk diffusion. The properties of nano-composite materials seem to be significantly dependent on the microstructure, i.e. the size, concentration, bulk- and size-distribution of nanoparticles;therefore we have studied by high resolution transmission electron microscopy the evolution of morphology of nano-composite films as a function of nominal metal deposition. The filled and empty electronic states of the hybrid organic-inorganic systems, energy level alignment at interfaces formed between metal nanoparticles and the organic semiconductor CuPc as well as the chemical interaction at the NP/oM interface were studied by UPS, XPS and NEXAFS methods.

从等离子体动力论出发,推导尘埃等离子体介电张量表达式,用它研究尘埃等离子体的低频电荷密度涨落.结果表明描述尘埃粒子“浓度”的参量P,及反映尘埃粒子电荷可变性的参量:尘埃粒子充电频率Ω_c,决定了尘埃等离子体中的低频电荷密度涨落的特征.对于P>l的尘埃等离子体,当Ω_(?)远大于(?)时,电荷密度涨落强度小,且涨落具有宽的频谱.将此结果用于讨论地球电离层,计算结果表明当电离层中存在的尘埃粒子的密度和尘埃粒子的半径在一定的范围内时,电离层中存在强度大的并具有尘埃粒子声波本征模频谱特征的甚低频电荷密度涨落.
