In this paper, a chemistry model including surface deposition and hydrogen etching is first described.
The chemistry model that has been used for SiC deposition and SiC etching by hydrogen is a simplified model including some organosilicon species.
Special attention has been given to the description of SiH4/C3H8 chemistry model.
On the first wafer, in the first millimetres, the layer surface presents a silicon-rich polycrystalline structure (fig. 1a), with silicon droplets (fig. 1b), while the other part of the wafer is covered with high crystalline quality layer (fig. 1c).
There is good agreement between experimental and simulation results when gas and surface chemistry include etching phenomena during the growth process.

The structure of the experiment device and the actual discharge effect are shown in Fig.1.
Raman spectra are an effective tool for studying the structure of diamond thin film.
G peak is scalable vibration of the E2g mode of sp2C-C bond in graphite structure.
In wear experiment, the wearing on the surface of DLC thin film comes from two destroying mechanisms of adherence and friction chemistry.
From Raman spectra, we can know the structure of the prepared DLC thin film not only differs from the lamellar structure of graphite, but also from the tetrahedral structure of diamond, it is a kind of amorphous state (amorphous form) structure

To indentify the influence of human activities on groundwater chemistry, fifteen groundwater samples, from the mostly exploited aquifers, were collected at Tanghai County.
Multivariable statistical methods have been widely used in many geologic fields as a reliable method to discuss the impact of human activities and natural processes to groundwater chemistry [7,8], especially during the early stage of the evolution of groundwater chemistry [9].
The purpose of factor analysis is to generate a new group of correlated elements from the initial variable dataset, rearranging data using fewer variables to present it in a better manner that explains the structure of the origin dataset.

The hydrophilicity, stability and surface structure of the coatings were measured by dynamic contact angles (DCA) in water.
The structure and purity of the monomer were confirmed by 1H NMR spectroscopy (INOVA400 spectrometer, Varian, Inc.).
The structures were identified by 1H NMR spectra (1:1v/v CDCl3:CD3OD mixture as the solvent).
The crucial factor might be the surface chemical structure of the materials.

In addition, they have been extensively reported in recent coordination chemistry and materials chemistry because of their importance in optical devices and asymmetric catalysis [2].
The structure was solved by direct methods and refined by fullmatrix least-squares refinement on F 2 using SHELXTL-97 [3c].
Results and Discussion The single crystal structure analysis shows that compound 1 crystallizes in the monoclinic system with chiral space group, P21, yielding a conventional R factor of 0.0291 and the Flack absolute structure parameter of -0.008(18).
The helical component of these structures contains only polyoxovanadium chains rather than the organic ligand, which has rarely been reported in comparable helical chiral structures.
