a collision
The North Qilian orogenic belt is an elongate tectonic unit that lies between the North China plate to the north and the Middle Qilian microplate to the south, and is formed by a collision of the two plates in the Caledonian.
      
A solution is obtained by the moment method based on the Boltzmann equation with a collision integral of Maxwellian molecules.
      
The influence of the solid particles on the carrier gas is taken into account by introducing in the kinetic equation a collision operator of special form.
      
In the two-dimensional case an approximate solution of the model equations is constructed, and steady nonlinear waves and their interaction in a collision are considered.
      
The properties of these distributions do not permit the realization of the moment method (in the case of a collision integral in Boltzmann form) in specific transport boundary-value problems.
      
The weak evaporation and temperature jump problems are solved analytically for the Shakhov kinetic equation with a collision frequency proportional to the molecular velocity.
      
Instability of a Collision Surface During High-Velocity Impact
      
A collision-radiative model describing the state-to-state kinetics of titanium atoms and ions at various stages of flight of laser-induced plasma was proposed.
      
A modification of the Enskog kinetic equation for dense gases and gas mixtures of hard spheres is given for the case where the particle diameter depends on the relative velocity in a collision.
      
These codes can be used as protocol sequences for successful packet transmission over a collision channel without feedback.
      
It has been found that the meteor streams observed from the Earth were most likely produced as a result of a collision with a small body.
      
At present, the trajectory of Apophis has been calculated more accurately, and a collision in 2029 has ruled out; the asteroid will pass Earth at a distance of about 37 000 km from its center.
      
Our analysis indicates that galaxies can merge, lose one or both of their gaseous components, or totally disintegrate as a result of a collision; ultimately, a new galaxy may form from the gas lost by the colliding galaxies.
      
An experiment on optical orientation of atoms established that the rate constant for spin exchange in a collision of a metastable 23S1 helium atom with a cesium atom in the 62S1/2 ground state equals (2.8±0.8)×10-9 cm3 s-1.
      
It has been shown that such a collision can be accompanied by the generation of radiation at multiple frequencies with a duration smaller than the durations of the initial pulses.
      
The average energy ?ΔE? transferred during a collision in the V-V process is comparable with the energy predicted by the statistical theory of ergodic transfer.
      
Formation of a sequence of ultrashort signals in a collision of pulses consisting of a small number of oscillations of the light
      
A collision of two parallel domain walls in a supersymmetric model is analyzed by using both the effective-Lagrangian approximation and a numerical solution to the equations of motion for the scalar components of the superfields involved.
      
For the first case, it is shown that, at low initial velocities, a collision of the walls is virtually an elastic reflection somewhat delayed in time.
      
Its unitarization leads to inelastic cross sections growing in proportion to s and corresponds to the pattern of a collision between black disks of radius about Ei1/2.
