  colliding particles
For a one-dimensional gas of elastically colliding particles of unequal masses, heat conduction is anomalous due to momentum conservation, and the divergence exponent of heat conductivity is estimated as α≈0.33 in k ~ Lα.

The properties of the collision integral in a quantum Boltzmann-type kinetic equation are studied under the conditions of spatially nonuniform distributions of colliding particles interacting with an external electromagnetic field.
      
Since the real number of interaction types for colliding particles exceeds that used in the classical Hund coupling scheme, there are intermediate cases of momentum coupling outside the standard Hund scheme.
      
The partial cross section of the resonant charge exchange process depends on quantum numbers of the colliding particles.

  scattered particle
The number of such peaks is determined by the distance between the impurities and the energy of the scattered particle.
      
The momentum-transfer scattering cross section is proportional to the average transfer of the longitudinal momentum of the scattered particle and can be expressed in terms of a force operator.
      
We note that, in principle, virtual vacuum processes in an external field influence the phase of the wave function of the scattered particle.
      
The three dimensional motion of the scattered particle (in particular the transfer of parallel momentum) increases the sticking coefficient by a factor of about three as compared to one dimensional treatments.
      
We investigate the dependence of the Debye-Waller factor on various parameters characterizing the adsorbate as well as the scattered particle.

The paper offers a new kind of particles collision model by only considering the effect which the gravity and resistance of air current have on the particles and omitting particles rotation and liftting force . Upon Codition that the conveying capacity is 9.13×10 - 3 Kg/s, the mixing ratio is about 0.3, by aking numerical calculatjon it is known that the velocity of different diame ter particles tends to be average because of the particles collision with each other.The particles collision is one of the causes of particles suspension.

A simple relativistic hadronic cascade model is given and then applied to simulate the reaction of Si(14.6AGeV/c)+Au.The △ resonance effects on the rapidity distributions of proton and pion and on the transverse mass distribution of proton are investigared.In this model,the longitudinal momentum of scattered particle is given by stopping law while the transverse momentum is sampled from exponential or Guassian distribution.The theoretical results are in a good agreement with the E802 new results and with the E810(E814)data.This indicates that that introduction of △ resonance is necessary for the better description of the reaction process.It is also convinced that the strong nuclear stopping at AGS energy is no doubt any more.
