摘要:

Small‐amplitude wave motion in a gravitationally stratified atmosphere permeated by a magnetic field consists, for each Fourier component with a certain frequency and horizontal wavenumber, of six quasiplane waves. Their mixture varies with height due to the continual interaction among these quasiplane waves. The simultaneous effects of compressibility, gravity, and a horizontal or a vertical magnetic field are shown by various wavenumber surfaces for decoupled plane waves.

摘要:

A criterion for the gyration phase being well randomized through binary collisions for a bounce motion of a charged particle in a magnetic mirror is investigated theoretically. The resultant criterion is seen to be easily satisfied even for the case of very rare collisions.

摘要:

The resistive torque exerted upon a rotating cylinder by a rarefied gas may be computed by an expansion in powers of the inverse Knudsen number. The first correction diverges logarithmically, and the renormalized theory should replace the argument of the divergent logarithm by the Knudsen number.

摘要:

A Hamiltonian for the microscopic plasma model is derived from the Low Lagrangian after the dual roles of the generalized variables are taken into account. The resulting Hamilton equations are shown to agree with the Euler‐Lagrange equations of the Low Lagrangian.
