This paper establishes a global attractor of hemigroup produced by the initial boundary value problem of generalized convection and expansion equation.
Boundary layer theorem, isothermal and isoflux vertical plates, asymmetric isoflux vertical parallel plates of free convection, optimum and maximum channel space will be discussed.
The relationship between arctic tropopause height and surface air temperature is discussed by using the aerological sounding and surface data during 1977-1990 in Beijing area.
Experimental study was performed using water as working medium to investigate the flow instability in a vertical narrow annuli with both subcooled and saturated boilings.
With the numerical simulated data of the storm, the structure and evolution of the helicity, superhelicity and their dynamical influences on the development of the storm are investigated.
The indicator light is lit, the switch of fan shall be turned on as soon as the instrument is warm, so that the heat produced can be forced to convect through the air channel.
