A new computation of the relaxation activation energy of P 1 peak in metallic glass is presented in this paper.

P1 sequence analysis indicated that adenosine(A) was rich, guanosine(G) and cytidine (C) were poor and A-G,C-T changing rates were high.

Methods A recombinant hIL-2-LuffinP1 DNA fragment was subcloned into an expression plasmid pET32a(+).

With the help of the dynamic stiffness matrix of saturated soil stratum and half space,the relation between the free surface motion of the half space and the value of incident waves under different saturated conditions are put forward;and the influence of the angle of incidence of P1 waves on free surface motion of the saturated half space is analyzed.
