The catatrophe theory was applied to the forest fire model, and the conservation of energy and mass of it was analyzed, the catatrophe has an elementary application in the forest fire model.

A systematic and exclusive measurement of the energy and mass dependence of particle production, correlations and collective effects in Au+Au collisions in the beam energy range 2-10 A GeV has been carried out on the experiment E895 at the AGS.

A greenhouse microclimate simulation model was developed based on the principle of greenhouse energy and mass (moisture) balances. Experiments were carried out in a Dutch Venlo-type greenhouse in Shanghai during three seasons to collect microclimate and crop data to validate the model.

Based on the energy and mass balance, Two hydrodynamics ingredients which affect the venting coefficient C_d have been derivative, and the simple calculate formula is gained.

Based on the study of mass and heat transfer law about thermolysis separation of compound particles in(1)paper,the energy and mass balance method was carried out in engineering de sign.

The Rayleigh-Ritz variational method is used with multiconfigurationinterraction wave function and restricted variation method to obtain the energies of 1s~22s~2p()~1P~o,1s~22s~2p()~3P~0,and 1s~22p~2()~3P states in berylliumlike CⅢ and OⅤ,including the mass polarization and relativistic corrections.

The bound state (1s 22s 2 1S ) and three excited states ( 1s 22s2p 1P 0, 1s 22s2p 3P 0, 1s 22p 2 3P) of beryllium like N 3+ are calculated using the Rayleigh Ritz variational method with a multiconfiguration interaction wave function. A restricted variational method is used to extrapolate a better nonrelativistic energy. The relativistic corrections and mass polarization are included.

The dynamic system model is coupled with geothermal heat exchanger model and heat pump unit model,which is based on the conservation of mass and energy.

This paper derives the formulas to calculate equal_diameter flow rate distributors and der ives the expressions to calculate the homogeneity the distributed liquids, the d eviation between the calculative and experimental values being about 0.23% for p ressures 1.73% for hole velocities.

The nucleus and the inner part of the coma are closely related to each other as physical subsystems, and physical processes in these regions are in close symbiosis because of the permanent exchange of both energy and mass.

The nucleus and the inner part of the coma are closely related to each other as physical subsystems, and physical processes in these regions are in close symbiosis because of the permanent exchange of both energy and mass.

The nucleus and the inner part of the coma are closely related to each other because of the permanent exchange of energy and mass; therefore, they are modeled consistently.

Relation between energy and mass in Bohr's essay on his debate with einstein

The analyzed correlation between the total kinetic energy and mass distribution of fission fragments is connected with the shell structure of the formed fragments of fission.

Quasi elastic and deep inelastic collision induced by ~(16)O+~(27)Al at the bombarding energiesbelow 5.3 MeV/A have been studied in detail.Experimental angular energy atomic charge dis-tribution and contour plots of the differential cross sections d~3σ/dEdΩdZ on E-θ plan are pre-sented,their evolution with the bombarding energies are analysed.The competion between quasielastic and deep inelastic collision as a function of the bombarding energies has been dis-cussed.

In 1986, experiment of ion implantation improvement of rice startedin our laboratory and Institute of Rice, AAAS. It was discovered thation implantation as a new mutagen caused high mutation rate of rice plantswith low damage. This method was then widely introduced for the mutationbreeding of other crops in China. In this paper, progress of biological effects and crop breeding by ioninjections was reported. General principle of the interaction between injectedions and biological materials was discribed, the...

The two-fluid model is a new method proposed recently to calculate the two-phase flow problem. In solving the governing equations of each phase, it also considers the momentum, energe and mass transmission between the two phases. The objective of this work is by using this model to calculate the vapour-liquid flow through a heated pipe. The result seems physically reasonable. This shows that the two-fluid model is a potiential way for analysing two-phase flow, but some of its assumptions have not yet been verified,...
