3.We obtain a new quark potential from the effective dilaton-gluon-coupling inspired by superstring theory, and by using this static potential, we explore the mechanism of quark confinement through calculations of the spin-average energy levels, the widths of the leptonic decays and radiative transitions for heavy quarkonium. The obtained results are compared with that of the Cornell potenial.

4.the latter is very important for the properties of the spectral structure of 86Nb and My(4) In this theoretic model Hamiltonian, the recoil term makes the energy levels slightlyregular but the Coriolis force depending on the spin makes the energy levels tend to bechaotic.
(3)在此理论模型中,体系哈密顿量的单粒子项和纯转子项对能谱结构的影响都很小,而反冲项和科氏力项对能谱结构的影响较大,其中科氏力作用尤甚。收藏指正
5.For the binary CrS, our computational results indicate that the spin-up(majority spin) electrons of zincblende CrS are metallic while there is an obvious energy gap around the Fermi level.
对于二元化合物CrS , 我们的计算发现zincblende 相的CrS 的自旋向上(majority-spin)的电子的能带是金属性的,而自旋向下(minority-spin)电子的能带在费米(Fermi)面附近有一个明显的能隙(Energy gap)。收藏指正
6.By using the rare-earth spectroscopy theory, the coulomb interactions between f electrons and d electron of 4 f N-15d configurations of rare earth are calculated. It is found that the energy of spin-allowed levels is higher than that of spin-forbidden levels for heavy lanthanide ions(N>7), and the energy difference between the spin-allowed and the spin-forbidden levels decreases with the increase in N.

7.In this paper,the bond operator representation of quantum spin S 1/2 is used to study the spin 1/2 bond alternating Heisenberg chain. The energy gap between the ground state and the first excited state is obtained. Our result is very close to the result of the exact diagonalization method.
应用S=1/2量子键算符方法研究了S=1/2反铁磁海森堡交替链的激发谱,该方法比严格对角化方法简单而有效.当J′=J时,第一激发态和基态之间能隙为零,这与各向同性的S=1/2反铁磁海森堡链的结论一致.当J′=-J时,第一激发态和基态之间能隙为0.5888J.收藏指正
8.In some ways, an electron is just like such a spinning sphere of charge—an electron has a quantity of angular momentum (its “spin”) and an associated magnetism, and in an ambient magnetic field its energy depends on how its spin vector is oriented.
就某种意义而言,电子可类比于一个旋转的带电小球:它带有角动量(就是「自旋」)以及伴随而来的磁性,而它的能量是由自旋向量与外加磁场的关系来决定。收藏指正
