常熟家谱姓氏趣谈

常熟在唐代时不足10万人，后因北方战乱，中原民众大量逃到南方，常熟人口大增，元代时达40万。到清代乾、嘉时，突破百万。人口的流动使常熟吸纳了许多外来姓氏。如南宋抗金名将周虎，祖籍临准，后迁居常熟。元朝时四川人董元斋，官居吏科给事中，因钟情常熟山青水秀，弃官后在此定居，所在地遂成董浜。元初名士顾细二，至大年间从浙江上虞移居常熟，他的后代山东按察使顾玉柱于嘉靖间将祖业扩建，植芙蓉数百，名芙蓉村；其子顾耿光又增植梧桐，并手植从海南移栽过来的红豆树二株，而把庄名改称碧梧红豆庄。清初湖北黄冈人王材任，康熙十八年进士，官至左佥都御史。其父王泽宏，官礼部尚书，自金陵来游，见这里山水秀美，     

Reading Disability in Chinese Children Learning English as an L2

To examine whether there are common or specific deficits of reading disability (RD) in first (L1) and second languages (L2), Chinese children (9–11 years, N = 76) with or without RD who learn English as an L2 were studied during a visual word rhyming judgment task. Evidence was found for common deficits in L1 and L2 in visuo-orthographic processes in left inferior temporal gyrus and left precuneus, as well as in phonological processes in left dorsal inferior frontal gyrus as children with RD showed less activation than controls in both languages. Furthermore, the visuo-orthographic deficit appears to be a RD effect, whereas the phonological deficit appears to be a reading/performance effect. Some weak evidence for language specific effects was also found.     

Hydrogen Bonding-Assisted Synthesis of Silica/Oxidized Mesocarbon Microbeads Encapsulated in Amorphous Carbon as Stable Anode for Optimized/Enhanced Lithium Storage

The practical application of silica-based composites as an alternative to commercial graphite anode materials is hampered by their large volumetric expansion,poor conductivity,and low Coulombic efficiency.In this work,a novel silica/oxidized mesocarbon microbead/amorphous carbon(SiO_2/O'MCMB/C) hierarchical structure in which SiO_2 is sandwiched between spherical graphite and amorphous carbon shell was succes sfully fabricated through hydrogen bonding-assisted self-assembly and post-carbon coating method.The obtained three-layer hierarchical structure effectively accommodates the volumetric expansion of SiO_2 and significantly enhances the electronic conductivity of composite materials.Moreover,the outer layer of amorphous carbon effectively increases the diffusion rate of lithium ions and promotes the formation of stable SEI film.As a result,the SiO_2/O'MCMB/C composite exhibits superior electrochemical performance with a reversible capacity of 459.5 mA h/g in the first cycle,and the corresponding Coulombic efficiency is 62.8%.After 300 cycles,the capacity climbs to around 600 mA h/g.This synthetic route provides an efficient method for preparing SiO_2 supported on graphite with excellent electrochemical performance,which is likely to promote its commercial applications.     

滇缅战役中的中美英关系——博弈论视角的解读

博弈论对于分析滇缅战役中中美英关系有重要的启示意义。为了追求各自收益的最大化,并把损失减少到最小限度,中美英三国在滇缅战役的合作与冲突中表现出"猎鹿困境"、"囚犯困境"、"胆小鬼困境"。     

加强修辞实践 增强修辞能力——修辞教学改革谈

修辞能力主要包括辨别能力、鉴赏能力和运用能力,教师要在修辞教学中引导学生加强修辞实践,在辨别修辞现象的实践中增强辨别能力,在阅读和鉴赏修辞现象的实践中增强鉴赏能力,在反复运用修辞现象的说写实践中增强运用能力。     

对我国社会的性质的思考

对于我国社会的性质,我们很多人并不能明确理解.改革开放后,我国提出了建设有中国特色社会主义理论,对社会主义的认识逐步加深,并揭示了社会主义本质.我们必须把马恩在19世纪科学预见的共产主义社会第一阶段,同20世纪出现的现实的社会主义社会相区别.     

静电照相数字印刷颜色均匀性研究

颜色均匀性是数字印刷颜色复制性能的重要指标之一,特别是对于打印大块平网、实地或渐变色等尤其显得重要。本文研究不同类型墨粉及纸张对静电照相数字印刷颜色均匀性的影响。实验结果表明：液态墨粉静电照相数字印刷机沿走纸方向和激光主扫描方向上具有较好的颜色均匀性能;固态墨粉静电照相数字印刷机沿走纸方向具有较好的颜色均匀性能,激光主扫描方向的颜色均匀性能不是很理想,需要进一步的提高和改善;不同纸张对于静电照相数字印刷的颜色均匀性能影响不大。
