A new method,the space-time conservation element and solution element(CE/SE) method for solving one-dimension convection diffusion equation is introduced.

In order to simulate micromechanical damage behavior of heterogeneous materials,the micromechanics model with the consideration of temperature effect near a crack-tip in a composite has been presented by using the method of analytical cells,and the influences of initial defect on mechanical properties of heterogeneous materials were analyzed.

This paper deals with the anti-lipid oxidation capacity of the hydrolytic glycone of bamboo leaf flavone glycoside,as well as its ability to scavenge hydroxyl radical (·OH).

The accuracy of numerical solution—finite element solution of the eigenvalue of second kind Fredholm integral equation is improved by the extrapolation method.

The otherness of fatality rate in every calculated unit interior and between the units applying different mining technologies are analyzed, a dualistic analysis calculation model is established to calculate fatality rate per million man hour and per million tons adopting different mining methods like mechanized and non mechanized mining methods or the like.
