It is beneficial for the fracturing because the deposition happened in Permian was far from the material edge and the content of quartz was high in the coal-bearing formation strata.
Hence, to create the new situation of multi-energy exploration and development, more analysis and test work involved in oil and gas exploration is necessary as follows: 1) Sampling and testing such as porosity and permeability 2) Test gas content during the drilling 3) The evaluation of source rock including organic carbon content, organic matter type, thermal evolution and so on 4) Carry on gas source correlation to make sure the sufficient of the gas supply Acknowledgements This work was financially supported by National Natural Science Foundation of China（41272181）, Research Fund for the Doctoral Program of Higher Education of China（20110023110003） and the Fundamental Research Funds for the Central Universities（2010YD11）.

Teaching Materials and Teaching Environment This does not include some of the edge of the textbooks and literature, such as "reading of Japanese literature and translation" (Science and Technology University Press).
These materials can be divided into two categories, one for the chronological history of literature.
Appreciation class materials have interesting strengths, students easily accepted.
I have several textbooks, in the three works Appreciation class materials, jointly select the "The Izu Dancer," "bird" and other works.
Selected or use materials, do not take into account the contemporary outstanding new work is really far away.

Introduction Carbon nanofiber and carbon nanofiber (CNT/CNF) has been widely used in chemistry, chemical engineering, materials science, biology, medical science and other fields because of their excellent properties.
They thought about how to control the CF surface structure, diameter, length and mechanical properties for the preparation of high-strength bulk materials.
These composites can not meet the potential mechanical properties of complex materials.
Experiment Raw materials.

However during dynamic impact loading of rigid materials, this condition is generally not fulfilled and determination of the Fmax force is not possible.
The physical background of the elector-emission measurement, that in certain materials in the moment of the break microstructural changes occur, that modify the properties of the surrounding electric space.
E.g. metallic materials always release electro-emission (EE) sign during breaking, while electro-emission activity of polymers and ceramics during failure are restricted for limited types of these materials.

For the plastic material, it characterized the resistance of the largest uniform plastic deformation of materials.
For there is no (or very small) uniform plastic deformation of the brittle material, it reflects the fracture resistance of the materials.
