conservation of mass
5.Under the assumption of the constant temperature, pressure, smoke concentration within each layer and by using conservation of mass, energy, components and the state equation of the ideal gas, a multi-layer zone model is introduced.
6.The dynamic significances of the circulation pattern of Jun 26th ,1999 are documented at the end of this paper from the mass angular momentum and moisture circulation perspectives, which suggest that the configure having cyclonic inwards and anticyclonic outwards in lower and upper troposphere respectively is of great benefit to the conservation of mass and angular momentum in the whole atmosphere.
7.We build various dispersion relations for temporal,convective and absolute instability analysis from both liquid and gas phase conservation of mass and momentum. There are two modes of solutions:para sinuous and para varicose.
9.GRAVITATIONAL MASS DEFECT IN REISSNER-NORDSTR?M METRIC (WITH CONSERVATION OF CHARGE)
10.The result shows that the general form of mass conservation can be applied to describe the percolation features of the porous media fluids in single phase, multiphase and solid phase in deformation media.
