This paper is the continuation of the authors' previous investigation([1]) in which the formula of total energy release rate at each point along the delamination boundary is derived by using variational method of moving boundary. In the present paper, the analytical model is reformed and the individual components of energy release rate are derived in the form of plate theory. The circular delamination embedded in circular laminates is analysed and some conclusions are obtained.

Electrochemical behavior of the transfer of H+ across polypyrrole membrane (PPM) was studied. The transfer process was quasi-reversible and mainly diffusion-controlled. PPM electropolymerized in water solution has better reversibility than that in CH3CN solution for the transfer of H+. The transfer process of H+ across the two kinds of PPM indicated that the PPM electrochemically polymerized was of asymmetry.

A theoretical model has been established for calculating the infiltration pressure of metal melt into the preform of ceramic fibers according to the basic principle of hydromechanics. There are three forces acting on the infiltration process in the model, i.e. viscous friction, capillary force, and gravity. The effects of the volume fraction of fibers (V-f) and infiltrating depth on the infiltration pressure are discussed. the results show that the infiltration pressure increases with tile increase of fiber volume fraction and infiltration depth. There is a linear relationship between infiltration pressure and infiltration depth. The effect of gravity on the infiltration pressure can be ignored.

Influence of Ti on MC carbide of M2 high speed steel was investigated by experimental observation, thermodynamic calculation and crystallographic calculation. With addition of Ti into M2 steel, large quantities of dispersed TiC particles formed in the steel melt at higher temperature than that of the formation of MC carbide. TiC can act as heterogeneous nuclei for the crystallization of MC carbide particles, and therefore promote the formation of blocky MC carbide.

Two new diterpenoids, named isodoternifolins A(1) and B(2), together with seven known compounds were isolated from the ethanol extract of dried stems and leaves of Isodon ternifolius (D. Don) Kudo. The structures of 1 and 2 were determined as 7 beta-hydroxy-6 beta,11 alpha,15 beta-triacetoxy-7 alpha, 20-epoxy-entkaur-16-ene and 6 beta,7 beta,15 beta-trihydroxy-11 alpha-acetoxy-7 alpha,20-epoxy-entkaur-16-ene by chemical and spectral evidence respectively.
