Raman spectroscopy is a simple and good tool for analyzing the structure of CNFs.
It has a high sensitivity to the disordered structures in carbon materials. 1550-1600cm-1 is the graphite band (G-band) which is produced from the high degree of symmetry and order of carbon materials, and generally used to identify well-ordered CNTs [7].

Since 1986, microwave irradiation as a heating method has found a number of applications in chemistry [15].
The crystal structures of the ferrite powders were examined via X-ray diffraction (XRD) with Cu Kа radiation.
Clearly, microwave heating produced a product with a much smaller and more uniform grain structure as shown in Fig. 2(a and b).

The composition, morphologies, structure, and the luminescent properties of the sample were characterized by element analyses, TEM, XRD, FTIR, TGA, UV-vis DRS, and PL spectra.
The structure of the sample was measured by a RIGAKU D/max-II B X-ray diffractometer (XRD) using Cu Kα radiation (λ = 0.1542 nm).

The luminescent intensity of fluorescent material is not only related to its structure, but also related to the environment.
The fluorescent quantum yield related to molecule structure can represent the ability of fluorescent emission, but compound molecules is always in a certain environment, so the research on excited state’s disintegration is inseparable from its environment, the luminescent intensity can be increased by changing external environment[5].

This is mainly due to the oxygen content in the fuel molecular structure and the low volatility of the oxygenated fuel.
Property DMMn has the general structure of CH3-O-(CH2-O)n-CH3 with n ranging from 1 to 8.
However, information about the heat resistance, pressure resistance and chemistry inert will be discussed in future.

He paints synergetic as a new discipline [1], but there are many fundamental researches to support its theoretical structure.
And there are lots of achievements on application researching in physics, chemistry and biology, military science, economics, urban planning and population cybernetics, and cognitive sciences [2-4]. [5] discusses what the essence of a control system is from the synergetic perspective.
Combine (1) with (2), it is obtained by Laplace transform: (3) (4) The structure of hydraulic cylinder driving control system is shown as Fig 2.
