Early stage sedimentation of basin evolvement during Mesozoic went through an overlapping process from continental to marine facies, sedimentary overlap started from the alluvial/fluvial facies, along with intrusion, eruption and pyroclaistic sedimentation, reflecting a upward deepened transgression sequence, which indicates a rift basin.

Influence of deposition voltage on nanoporous ZnO films by electrochemical synthesis;

The influence of deposition voltage on the phase composition and microstructure of HAp coatings was investigated.

The effect of deposition voltage on auxiliary heat PCVD-TiN coatings has been studied.

The effect of deposition pressure on the properties of PC film;

The structure and properties of the films during the course of deposition and polymerization were dominated by deposition pressure.

Effects of deposition pressure on structure and properties of thin film were investigated using XRD,SEM,UV-Vis spectrometer and FT-IR four-probe resistivity meter.

To lower the surface roughness of diamond thin films by improving the CVD depositing technology, two kinds of new technical methods are proposed by appropriately increasing the carbon source concentration and controlling the deposition pressure.

For the diamond films prepared at high deposition pressure,scanning electron microscope images show clearly the crystals and the Raman spectra have sharp peaks at 1332 cm-1,which shows good quality of diamond films.

The influence of different substrate temperature and different deposition pressure on the crystallinity of GaN films are systematically studied by X-ray Diffraction(XRD),Atomic Force Microscope(AFM).
