N-heterocyclic compounds have important functions in pharmaceuticals, materials chemistry, organic synthetic chemistry, and dyes, and therefore have attracted extensive attention [5].
Especially the synthesis of some benzo N-heterocyclic compounds, such as indole, quinoline and their saturated derivatives is very important, because these structures exist in some natural products with physiological activity.
Quinoline compounds are widely used in medicinal chemistry, especially anti-malarial, anti-tuberculosis, anti-tumor and anti-viral drugs.

The result shows that: the crystal structure of zeolite P has been determined in the tetragonal crystal system, lattice constants are 10.049Å, 10.047 Å and the crystallinity of zeolite P is 97%.
The basic structure unit is aluminium-silicon tetrahedra linked by sharing of oxygen atoms.
Because of the special structure, zeolite has been used in a lot of fields, such as ion exchange (K+, NH+), chemical separation, adsorption, heterogeneous catalysis, host/guest chemistry.
It implied that the crystal structure of zeolite are all destroyed, and exist in amorphous amorphous as precursor.

Biominerals have fewer degrees of freedom, and undergo three changes in state from a disorganized structure to a structured arrangement.
The case for a material with a chemistry of hydroxyapatite (Ca10(PO4)6(OH)2) is shown in Fig 1.
An amorphous phase consisting of a chemistry that allows crystallization of apatite occurs in mollusca, chordates and arthropods.

Fundamental Theories for Stability Analysis Factor of stability is a ratio of the critical load at the failure of the structure to the service load of itself.
The factor of stability is defined as follow, (1) Where is the critical load at the failure of the structure, and are the dead load and the live load applied to the structure.
For multi-degree-of-freedom system, the problem can be converted as the solving of the structure’s eigenvalue, in other words, the minimum eigenvalue can be considered as the critical load for instability.

So organic electronics emerged as a dynamic field in terms of research and development includes chemistry, physics and technology [1-6].
The results obtained were compared with the structure of the surface morphology of a thin layer of Fe-porphyrin standards.
Clearly observed from the figure, the surface structure of the thin layer was formed of islands.

In order to synthesis the porous low-k films, sol-gel spin coating method is used due to its ability to introduce porosity and less polar bonds in the film matrix by changing solution chemistry [2].
To study the electrical properties of the deposited films, the MIS structure was developed by fabricating Al\low-k\Si structure.
The C sample is prepared by synthesizing a Si-O-Si structure connected by a benzene ring, and the film contains a pore structure having a dielectric constant of 2.5.
