Fig. 1 SDG Data modeling Structure modeling The causes and effects of fault propagation in complex system are related with its hierarchical structure.
Structural model is established by packaging all diagnostic knowledge to the framework of product structure tree model.
FFA based on the product structure tree model and system principle is carried at first.
The results of analysis are stored into relational database in form of table structure.

At the thickness up to 100 nm films had single-crystal structure, and in film layers with thickness more than ~ 100 nm the structure was already polycrystalline.
Such method of chemical vapor deposition (CVD) is widely used for filming with perfect structure.
Figure 1 shows the structured diagram of measuring stand of dielectric characteristics of thin-film specimen.
Figure 2 presents schedules of dependence of loss angle tangent tgδ value on h thickness of ferroelectric structure Ba0,8Sr0,2TiO3 which is grown up on MgO and Si single-crystal substrates, as well as on the diamond-like film deposited on a silicon substrate by a plasma chemistry method.

Usually adapter uses simple entity structure such as cylinder or cuboid, but the simple structures of adapter can't satisfy the damping performance requirements of submarine-launched missile, therefore it needs to redesign the adapter structure according to the performance requirements of adapter[1].
Especially in the submarine-lunched system, the missile adapter is widely adopted V-shape structure, which is used for providing support and damping[2-7].
Optimized the structure of V-sharp adapter, it has a guiding significance to design and test of the submarine-launched missile launch system.
The structure of V-sharp adapter is shown in figure 1.

This product is widely used in petro-chemistry, rubbish burning, dope and treatment for waste gas and in water industry and catalytic converters.
Figure 1 shows the honeycomb cordierite structure.
The sintering process caused interaction between the molecules or atomic structures of the raw materials.
Hence it was not possible to produce the true honeycomb structure.

This may due to accumulation of a-C structure at the outer part of tube.
The sample were also covered with non-tubular carbon structure.
D peak corresponded to the disorder or defect of the carbon structure which was observed at around 1347.11-1351.72 cm-1 while the G peaks indicated the graphitic structure was seen at 1579.85-1591.26 cm-1.
Quantum confinement in 1D structure would improve the carrier transport or mobility [18].

However, due to the strong hydrophilicity caused by silicon-oxygen structure at its surface and the strong hydrolysis of interlayer cation, it is difficult for unmodified bentonite to adsorb organic matters in water [3-4].
