Based on the consideration of coupling of the rotational and thermal evolution, I research two kinds of heating mechanisms induced by the spin-down of the star: crust deconfinement heating and r-mode dissipation heating.
The additional attenuation of the power spectrum density with respect to the WKB model can be written as exp [-2(r-ro)/λ], where r=0.87 AU, ro=0.29 AU, λ is the dissipation length.
In the present paper, we deal with the long-time behavior of dissipative partial differential equations, and we construct the approximate inertial manifolds for the nonlinear Schr?dinger equation with a zero order dissipation.
The relative dielectric constant εr and the dissipation factor tgδ of the PZT thin films were measured with an LCR meter and were found to be 158 and 0.04-0.005, respectively.
The sap flow density, water consumption, and related environmental factors were also measured using thermal dissipation method and ICT-2000TE (Transpiration-Environment) automatic measuring system for tree transpiration and environmental factors.
From a systematic analysis of the whole history of the protoplanetary cloud and the observational facts of the Earth's atmosphere, we propose a new theory on the Origin of the atmospheres of the Earth and the planets. For the Earth-like planets, there were profound primordial atmospheres originated from the protoplanetary cloud by the accretion of the embryoes of planets. These primordial atmospheres has existed in a time scale of 10~8—10~7 years and were composite from chemically reducing gases. The presen...
In this paper, we propose a model to explain the energy supply of cosmic γ-ray burst by means of magnetic energy annihilation in neutral sheets formed in local active region on the magnetic white dwarf. According to this model the instability process in plasma consists of two phases, namely, the thermal explosive phase and the steady annihilation phase. The magnetic energy stored in the local source is efficiently converted into kinetic energy and cosmic dissipation energy of plasma at a rate that is ...
In this paper, the propagation of perturbations in the stellar atmosphere strati fied due to gravity with steep density drop is studied. The results obtained in our work is very different from that derived under the adiabatic assumption. It is shown that the dynamic property is of importance to the propagation of perturbations in the stellar atmospllere and the height where the shocks dire formed. our calculations in dieate that the small perturbations under the photosphere can’t propagate outwards with flu...
