A method of accelerating molecular dynamics simulation for atomic diffusion in metallic interface;

Rheological Behavior and Atomic Diffusion of Pd-based and Zr-based Bulk Metallic Glasses;

It isconsidered after analysing and processing the above n1entioned phenomena by means of dy-namic theory that the atomic diffusion of P and Ni can cause the crystallization and equiphasesettling of Ni and P forming metallurgical combination between the pla.

It has been found that atom diffusion is strengthened with the increasing of temperature and treatment time,new kind of compound emerges in ceramic layer and interface, all these can remarkably improve the interface shear stress,reduce the brittleness of ceramics.

The present situation of experimental studies on atom diffusion at metal/metal interfaces induced by energetic ion irradiations is reviewed.

The atom diffusion at the interfaces and necks of specimen under SPS was also investigated and compared with Hot Pressing(HP).

Further Studies on Nucleon-Nucleon Scattering and Non-perturbative Renormalization;

Beginning from 90 s, employing the QCD-based effective field theory methods, Weinberg proposed to construct the potential of nucleon-nucleon interactions order by order from chiral perturbation theory and then calculate the T-matrix using Lippmann-Schwinger equation to obtain the phase shifts for nucleon-nucleon scattering.

In the article we finely study on the choice of integration contours in Greed′s functions in the atomic scattering theory,and draw a conclusion that the choice of manifold integration contours are equivalent by using of the theory of mathematics physics and complex function method.
