本文在相对论平均场理论框架下,用手征对称破缺模型讨论核物质的可压缩因子,用局域的Lorentz变换和Scaling坐标方法讨论了巨单极和巨四极共振激发能量.将所得结果与QHD(Quantum hadrodynamics)的σ-ω模型计算结果比较,发现可压缩因子、巨单极及巨四极态的激发能都比σ-ω模型的计算结果更加接近于实验值. 相似文献

用Poisson-Boltzmann方程,计算了在具有单价离子的电解质溶液中均匀地带同号电荷的两无限大平行平板间的有效相互作用,以及用Derjaguin近似研究了边界对带电胶体球的影响.不考虑微离子相互作用时,两带电平板只有排斥作用,而且边界条件(面电荷密度)的改变对它们之间的有效相互作用影响不大.带电平板与带电胶体球之间的相互作用也有类似规律.

The dynamics of two confined colloidal particles is studied by means
of Brownian dynamics simulation. The autocorrelation function and
cross-correlation function of the two colloidal spheres are computed
by utilizing the formulae of hydrodynamic diffusion matrix expanded
to different orders, as well as the accurate tensor through
numerical algorithm. Furthermore, the numerical results are compared
with the experimental results and the theoretical approximation. It
is found that the relatively simple theoretical approximation gives
good predictions when two spheres are far away from each other, but
fails when the two spheres are very close. 相似文献
