We investigate the differential cross sections of the elastic electron scattering from ~(12,16)O and ~(28,32)S by the relativistic partial-wave expansion method using the static charge density distribution from the self-consistent relativistic mean field model and also calculate the charge form factor of ~(12,16)O and ~(28,32)S.

用相对论分波展开法研究了电子与12,16O和28,32S弹性散射的微分截面以及12,16O和28,32S的电荷形状因子,其中核的电荷密度分布利用自洽相对论平均场模型来计算。

In this paper, the Payne-Whitham-type macroscopic model is discussed for the properties of describing the propagation of perturbations along the equilibrium traffic flow through the wavefront expansion techniques.

文章采用波前展开的方法,研究Payne-Whitham型宏观交通流模型描述扰动沿交通流波动的特性,同时给出了相应的稳定性条件。
