The results indicate, the ground state energy increased quickly as the decrease of ZnO QD radius, when the radius decreased to the effective Bohr radius of ZnO exciton (aB=1.8nm), the ground state energy is 488meV higher than the conduction band bottom, about 8 times of binding energy of ZnO free exciton. When the radius is larger, the ground state energy inclined to a constant (under conductor bottom about 65meV), approximate the binding energy of the exciton in bulk crystal ZnO.
计算结果表明,激子的基态能随着粒径的减小而迅速增大,当粒径减小至ZnO的激子玻尔半径时,其基态能高出体相ZnO禁带宽度488meV,约为ZnO自由激子结合能的8倍,而当粒径较大时,其基态能比ZnO导带底低65meV,与ZnO自由激子的结合能基本一致。

The B3LYP/6-31G calculations on the four complexes show that the largest interaction energy is-13.98 kJmol^(-1) in the complex composed of HMX and hexaazacalix [3]-p-triarene [3]-2-amido-1, 3, 5-triazine. Results show that intermolecular interaction energies of azacalix [6] arenes with substituted groups are stronger than that without substituted groups, and intermolecular interaction energies of azacalix [6] arenes with amido groups are stronger than that with nitryl groups.

The spermatozoa are embeded in a extracellalar matrix composed of high dense fibrils matrix and flocculent and concentric vesicles similar to that in the primary spermatophore layer, but the later lack of spermotozoa. The flocculent and concentric vesicles are often seen to release their contents around the main body of spermatozoa. The spermatozoa may absorb the contents to form vesicular zone and membrane zone in sperm nucleu. The secondary spermatophore layer is distinctly subdivided into inner region and outer region. The loose outer region consists of canaliculated reticulum and large flocculent vesicles.

The results of calculation will be fundmentally consistent with the experimental values.In addition, we calculated dibenzene chromium and its derivatives, ferroceneand its derivatives. The former had higher symmetry. We studied the substituenteffects by calculating their NMR spectra. The results show that: when we add asubstitute group on one ring of dibenzene chromium, the substitute group will affecttwo benzene rings. The effect is similar to the effect of branched alkanes, namely:the effect on neighbouring groups has transmissibility. Furthermore, the nearer theneighbouring group is, the stronger the effect is. This effect is observed not only onthe substituted ring, but also on the unsubstituted ring.
