The pressure drop of pipe increases with increasing of flux, liquid density, liquid viscosity, particle density and particle volume density.
管路压降随着流量、颗粒密度、颗粒初始加入量及液相介质密度和粘度增大而增大。

Using the periodic orbit theory, we computed the quantum level density of a particle in the two-dimensional harmonic oscillator potential with and without the magnetic flux line for different cases.
