In this notation A represents a mono-, bi- or trivalent ion, B denotes a tetra-, penta- or hexavalent ion, and m is the number of BO6 octahedral in each pseudo-perovskite block (m=1,2,3,4,5) [2].
The platelike morphology of the SBT7 ceramic grains was observed.

The required security capabilities require that we are able at run-time to take decisions about the types of services interacting, the current context and the security policies from a number of different domains.
Semantic Web technologies are currently the only viable option for enabling us to perform such reasoning, since they allow for a more fine-grained description and reasoning over the relevant issues in a manner that could also address the challenges placed by the open and heterogeneous nature of the service-oriented environment envisioned.

Data sources Model is based on a large number of experimental data, especially the variable test data from Yasin(1998) [2] and Yasin Tatsuoka(2000) [3], who had done many stress path [6] of saturated close-grained Toyoura sand drainage tests along with a series of accurate stress testing [7] in geotechnical engineering laboratory at the university of Tokyo.

Models with crystal plasticity require detailed information about the deformation mechanisms and texture taking into account the crystallographic orientation of individual grains, thus needing unreasonable computational time for simulations at structural level.
If the number of elements were increased, the results would be much better.

Since the early demonstration of bulging of superplastic Zn-Al eutectoid alloy using a small air pressure [1], a number of mathematical analyses were reported to predict biaxial bulging behavior [2,3].
Results and Discussion The average grain size of the sheet received is 15micron.

Figure 2 The XRD pattern of the samples calcined at 1200℃ for 5 h by grinding at different times Others peak number is reduced while YAG characteristic peak becomes stronger gradually, along with the increase of ball milling time.
In addition, after ball milling, the powder generated multiple fresh surfaces, the particle size was decreased and the specific surface was increased which contributed to improving the surface energy of crystal grains and reducing the heat-treating activation energy.
Meanwhile, a large number of high energy defects could be introduced in the crystals in the process.

The grain size distribution is shown in figure 2.
Reflection targets were attached onto the wall facing units at a number of pre selected locations.
Typical records of lateral wall displacements measured at a number of selected survey targets attached onto the wall facing are plotted in Figure 5.

Introduction For improving the emergency handling capabilities, a large number of emergency command information systems have been built in China recently.
Accordingly, larger-grained command business service will be formed to meet more advanced command business needs of command force.
The redundancy based reliability model described with cycle flow As it is shown in Figure 4, g is cycle number and this structure can be seen as cascading g sequence flow structure.
