基于改进等分节点法的启发式布局算法

针对集成电路标准单元模式的布局问题，提出了一个全新的基于改进等分节点法的启发式标准单元布局算法(TETP)，该算法在优化布局过程中采用改进的等分节点法寻找单元目标位置，同时结合局部寻优的启发式算法，对MCNC(Microelectronics Centre of North-Carolina)标准单元测试电路进行实验。结果表明，与布局工具Timber Wolf7．0和FengShui相比，电路布局的总线长度分别平均减少了16％和17％。     

技术视野下的人与自然关系

为构建人与自然的和谐相处,现代技术的“双刃剑”效应需要人们理性的思考和认真的对待。本文从马克思主义哲学的角度阐述了技术不同于科学的内涵、负面效应及人的责任;从分析技术悲观主义、技术乐观主义与技术现实主义的基础上审视技术价值观的选择,实施可持续发展的生态文明模式;并要求在意识、科教、法律与道德和国际合作等方面采取措施,促进人与自然关系的和谐发展。     

人文视野里的语文和语文教育

人文是人对自身本质特性的思索和探寻,包括理想人性及其实现方式,这种实现方式在人类社会主要体现为文化行为.人文视野里的语文表现出学科文化内蕴的综合性,言语符号内容与形式的同步性,人文精神展示的完整性等突出特点.要在语文教学中凸现人文性,必须注重教学行为的人文方式,教学材料的人文底蕴,文本解读的人文基点.

The Symbolic Meanings of the Forest in The Scarlet Letter by Nathaniel Hawthorn

The symbols in Hawthorne’s masterpiece The Scarlet Letter have the characteristics of indefiniteness and multi-sense. Each character brings out a different side of the forest,however the forest also brings out a different side in each character.The forest reflects multi-dimension. The image of ＂woods＂ or ＂forest＂ in The Scarlet Letter manifests Horthorne＇s understanding and exploring of the human nature. The forest may stand for individual freedom,innocence,truth,danger and evil as well.     

Theoretical study on the lithium bond interaction of furan homologues C_4H_4Y (Y=O, S) with LiCH_3 via DFT and MP2

The optimizations geometries and interaction energy corrected by BSSE of the complexes between C4H4Y (Y=O, S) and CH3Li have been calculated at the B3LYP/6-311 G** and MP2/6-311 G** levels. Three complexes were obtained. Abnormally, the calculations showed that all the C10—Li14 bond lengths increased obviously but the blue-shift of C10—Li14 stretching frequency occurred after formed complexes. The calculated binding energy with basis set super-position error (BSSE) and zero-point vibrational energy corrections of complexes I―III is ?45.757, ?35.700 and ?39.107 kJ·mol?1, respectively. The analyses on the combining interaction with the atom-in-molecules theory (AIM) also showed that a relatively strong lithium bond interaction presented in furan homologues C4H4Y---LiCH3 systems. Natural bond orbital theory (NBO) analysis has been performed, and the results revealed that the com- plex I is formed with n-σ type lithium bond interaction between C4H4O and LiCH3, complex II is formed with π-s type lithium bond interaction between C4H4O and LiCH3, and complex III is formed with π-s and n-s type lithium bond interactions between C4H4S and LiCH3, respectively.
