摘要:

In the levitated spherator, a plasma confinement time of150 ∼ 200msec was obtained at a plasma density of 2 × 1011cm−3and an electron temperature of 1 eV. This confinement time is 1/3−1/6 of the classical decay time. It was observed that the confinement time increased with an increase in the electron temperature in the range of 0.1 to 5.0 eV. At higher electron temperature the plasma decay time was reduced with an increase in the electron temperature.

摘要:

The effect of variation of the coefficient of thermal expansion through a fluid with a linear temperature gradient at the onset of Be´nard convection can be resolved in terms of a nonlinear density profile.

摘要:

There is a close relation between the Knudsen number dependence of the drag coefficient for a macroscopic body in a gas stream, and the density dependence of the transport coefficients for moderately dense gases in both two and three dimensions.

摘要:

The dispersion relation for backward‐stimulated Brillouin scattering shows that near threshold the most unstable reflected wave rapidly outruns a laser driven underdense plasma. Laser energy absorption may, however, be affected at power flux densities above 1015Ws/cm2for1.06 &mgr;radiation.

摘要:

The characteristic properties of the electromagnetic wave instability driven by an electron thermal anisotropy are presented in terms of asymptotic pulse shapes computed for typical laboratory parameters. Maximum spatial growth rates for the convective regime are also given.
