Further, the atomic valence orbital electronegativity can be also obtained from TAE of an atom.      所指出的新电负性标度χCL与总吸引能TAE除以原子价壳层电子数目Σni之值即平均吸引能成正比：χCL＝0．1813AAE＝0．1813TAE／Σni＝0．1813（ΣniEi＋EA）／Σni，进一步从原子总吸引能TAE可确定其价轨道电负性。 短句来源      Regarding 0 VEI, 1VEI,total ionization energy of valence shell electrons n iE i and total valence shell electrons n i as fundamental parameters,the electronegativity of element can be defined as follows: X N =0.444067+1.190653(1-1.32775/n i) ( 0VEI)-3.154675( 1VEI)+0.134591(n iE i/ n i).      以0 VEI,1VEI,价壳层电子总离子化能 ( niEi)和总价电子数 ( ni)为基本参数 ,定义了元素的电负性 :XN=0 .44 40 6 7+1.190 6 5 3(1- 1.32 775 / ni) (0 VEI) - 3.15 46 75 (1VEI) +0 .134 5 91·( niEi/ ni) . 短句来源      Electroaffinity or electronegativity X LL is approximately proportional to the average ionization energy B , the total ionization energy U divided by the number of atomic valence shell electrons N , due to its vecy small electron affinity E .      应用原子的平均电离能来近似度量电亲性或电负性。 所提出的电亲性新标度XLL与总电离能U除以原子价壳层电子数目N即平均电离能B成正比 ,进一步地从原子总电离能T或平均电离能B可确定其价与杂化轨道电亲性。 短句来源      A NOVEL ELECTRONEGATIVITY χ CL FOR ELEMENTS AND ORBITALS BASED ON AVERAGE ATTRACTING ENERGY OF VALENCE SHELL ELECTRONS IN GROUND STATE FREE ATOMS      一种电负性新标度:基态自由原子价壳层电子平均吸引能 短句来源   相似匹配句对      Valence Shell Orbital Hybridization Theory      试论价层轨道的杂化——兼论杂化轨道理论与价层电子对互斥理论的统一 短句来源      Valence shell electronrepulsion theory and its applications      价层电子对互斥理论及应用 短句来源      The Shell Of History      历史之壳 短句来源      Shell Seeks for Change      壳牌能否再续辉煌? 短句来源      Valence of French verbs      法语动词Valence 短句来源 查询“valence shell electrons”译词为用户自定义的双语例句     我想查看译文中含有：的双语例句 为了更好的帮助您理解掌握查询词或其译词在地道英语中的实际用法，我们为您准备了出自英文原文的大量英语例句，供您参考。   valence shell electrons For atoms of a certain row of the periodic system, this quality appears to depend not only on the number of basis functions used in the calculations, as is usually accepted, but also on the number of valence shell electrons of the various atoms. 例句来源       The molecules BeH2, Be2H4 and Be3H6 are investigated by means of ab initio calculations including the electron correlation of the valence shell electrons. 例句来源       Internal conversion of valence shell electrons: Measurement and analysis for the 10.84 keV transition in206Bi 例句来源                The crystal structure of (C5H7S2)2 ((SbCl3)2S) has been determined by the heavy atom method and refined by full matrix least squares technique on CAD-4 diffractometer to R=0.067. The space group is C2/c with a=14.531(2), b=11.265(2), c=15.364(3)A. β=112.72(1) and 2=4. The result shows that the crystal is ionic,consisting of a planar five-membered ring (C5H7S2)+ cation and a((SbCl3)2S)2- anion. In the anion, each Sb atom makes use of foursp3d hybrid orbitals to combine with three Cl atoms and a bridging S at...             [C_5H_7S_2]_2[(SbC1_3)_2S]的晶体结构采用x射线衍射法测定。晶体属于卑斜晶系,空间群C2/c,a=14.531(2),b=11.265(2),c=15.364(3),B=112.72(1)°,Z=4。在CAD-4四圆衍射仪上收集数据,用重原子法解出结构并经全矩阵最小二乘法修正。R=0.067。研究表明,该离子晶体中,[C_5H_7S_2]~+的C、S骨架具有平面构型,而[(SbCl_3)_2S]~(2-)的构型是:Sb原子周围形成缺位的准三角双锥构型,两个Sb准三角双锥通过共用S桥形成二聚体,∠Sb-S-Sb=98°,整个阴离子具有C_2对称性。 文摘来源          In order to study the alternations of properties in d~(10)electronic config- uration metal ions,we heve introduced turnning scale parameter,which is used to represent the potential energy of valence shell electrons.These para- meters with the effective nuclear charge Z*and atomic radii of metals rm have been calculated and some correlative phonomenon may be explained.The result is likely to be reasonable.             为了解释 d~(10)离子性质具有同族交替的现象,本文拟定以离子的有效核电荷 z 对金属原子半径 rm 之比,来表征价层电子位能函数.此参量 z~*/rm 定义为“拐标”。用拐标对 Z 作图时可得到同族交替变化的山形曲线。推测这种电子位能的山形变化是由于 d 或 f 轨道径向分布的拖尾所引起的。按此所得的结论同重原子的相对论效应完全一致。 文摘来源          The Carbon KLL Auger yields from CH4, CH3Cl, CHCl2F and CF4 have bees measured for 4He+ bombardment in the incident energy range of 0.8-2.0 MeV.The yields are seen to vary significantly with the chemical environments with variations greater than30% between CH4 and CHCl2F,CF4 yields. The variation seem to be reproducible by two scaling laws, that based op the inelastic scattering of Auger electrons by the various molecular components and that uses the effective numberof valence-shell ele...             实验测量了CH_4,CH_3Cl,CHCl_2F,CH_4在0。8—2。0MeV~4He~+束流轰击下碳原KLL俄歇电子产生率,结果表明产生率随碳原子化学环境的不同有明显的差别,CH_4和CHCl_2F,CF_4的俄歇电子产生率差异达30%以上。这种差异和非弹性散射修正或碳原子外层有效价电子校正结果均相符合,虽然前者符合可能稍好。测量结果显示可能存在其他因素或综合因素对产生率的影响。 文摘来源   << 更多相关文摘         相关查询: valence shell valence-shell valence shell electron valence shell electronrepulsion valence shell electronic valence electron shell valence shell excitation valence shell electron pair valence shell electronic structure shell valence valence shell electronrepulsion theory  对查询结果不满意
