The damage to the ferroelectric properties caused by the impregnation of hydrogen would be due to pinning of the domains, which is pinned by the lack of oxygen derived from the inside of the film by a strong reduction ambient of hydrogen treatment process [5].
Fig. 2 XPS data of Bi element at interface of Pt top electrode and SBT thin films: (a) before and (b) after annealing at 300 � in 5 % H2 ambient for 10 min.

Introduction With the development of the aerospace industry, weight reduction and comprehensive performance requirements for materials are strongly demanded.
After welding,the metallographic specimens were cross-sectioned through the centre of welded joint, then polished and etched in a solution of 1%HF +1.5%HCL + 2.5%HNO3,and the microstructures were observed by light optical microscope (LOM).The welded parts were subjected to tensile-shear loads with the head speed of 1 mm/min to determine the tensile-shear force in a universal testing machine ,the final figure is an average of the three sets of data under the same welding parameters.

Kaolinite organic intercalation compound was also used as starting material to synthesize non- oxide ceramics by carbothermal reduction and nitridation processing [3].
The data show that the hydrogen bonds between the inner surface hydroxyl groups and the adjacent siloxane layer were broken and that the formamide molecule was hydrogen bonded to the inner surface hydroxyl groups because of the formamide intercalation.

The driving force for the surface segregations are reduction in surface free energy, bulk elastic strain energy, and size effects.
The thermal properties of the segregated surface are then computed by simply averaging over the configurations produced in the simulations and the compositions corresponding to the equilibrium are calculated. 3.0 Surface segregation of Au-Ti nanoparticles The experimental data on surface segregation in Au-Ti nanoparticles have not been reported in the literature to date.

Results and discussion Biochemical evaluation of the seeded Bonelike  showed that human bone marrow cells proliferated during approximately three weeks and attained a stationary phase afterwards, as shown by the results concerning the MTT reduction and total protein content (Figs. 1 A and B).
Bonelike  is composed of an HA matrix with bioresorbable β- and α- tricalcium phosphate phases (XRD data not shown), which are more soluble than single HA and liberate Ca and P ionic species to the local environment.

Because of the small amount of feed, the feed force data is also smaller, the axis deviation of the hole in this case see figure 3.
This shows that: ①When decreasing the feed speed, the feed force reduction, so it can improve the linearity of the hole.
