Based on the analysis of the excitation spectrum, we obtain the superfluid-Mott-insulator phase transition condition, and superfluid velocity of ultracold dilute gas of bosonic atoms in an optical lattice, and point out that the velocity of superfluid can be experimentally adjusted by controlling the parameters of optical lattice.

On the basis of single phase lattice Boltzmann model,we construct anew and simple lattice Boltzmann model,which is more physical and computationalefficient,to simulate immiscible two-phase flow by introducing an item to strengthen thepressure gradient effect for particles with the same color and weaken those with differentcolors so that two fluids can be separated.

On the basis of analyzing the principles of interleaver filters of the interference of polarized light and planar lightwave circuit-type lattice structure, the equivalent mathematical representation of the spectral transmittance of the two kinds of interlearers is revealed. The equivalent relationships of the structural parameters of them are given.

The dislocable distribution of pedestrians in initial status as well as movement process enhances the interactions among pedestrians.The walking speed is adjustable because the pedestrian can move one or more small grids in each time step.The exit is figured more accurately because of the finer lattice,which reduces the probability of pedestrians passing the exit abreast. When one pedestrian walks in the middle of an exit and no pedestrian could share the exit with him,then the evacuation efficiency is decreased.
