Our calculated results may be one of the reasons why Nb doping can improve oxidation resistance of γ-TiAl. 1 Introduction γ-TiAl alloy is one of the most widely investigated materials, due to its potential application in the aerospace and automotive industries.
As a material relating to the oxidation resistance of γ-TiAl, TiO2 has not been theoretically studied.

While the demand for the material and spiritual civilization greatly enriched, the demand for ecological civilization are gradually improving.
Ecological civilization is an integrated matter of material civilization, spiritual civilization and political civilization[2].
The strong economic strength of the southeast coastal regions guaranteed research and development of ecological protection technology and application, which made these regions had the advantage in eco-environmental protection such as development of new production technology, efficient recycling of energy and raw material, purification treatment of pollutants, priority to the development of high-tech industry, clean energy research and development etc.

Parameter Sensitivity Analysis of Airport Rigid Pavement Thickness Using FAARFIELD Program Merhej Tammam1, a and Feng Decheng2, b 1Ph.D Student, School of transportation Science and Engineering, Harbin Institute of Technology, Harbin 150001, P.R of China 2Professor, School of transportation Science and Engineering, Harbin Institute of Technology, Harbin 150001, P.R of China amerhej78@yahoo.com, bfdcgxy@vip.sina.com Keywords: Sensitivity analysis; FAARFIELD; airport rigid pavement Abstract.
FAARFIELD requires five groups of design input data: 1) airplane mixture information including airplane type, gross weight number of annual departures and percentage of annual growth; 2) concrete flexural strength (modulus of rupture, MOR) which measured in accordance with ASTM C79 [2]; 3) Subgrade reaction Modulus; 4) Design life; and 5) material Properties for Subbase Layers. [1] Sensitivity analysis can help in identifying critical control points, prioritizing additional data collection or research, and verifying and validating a model. [3].

However, the inherent properties of magnetic materials, lead to difficult to adjust the magnetic field of the motor air gap, and this restricted the use of PM motor, especially in electrical vehicles and other areas that needed wide speed regulation.
The DSPM motor, which stator and rotor are both the salient structure, is the switched reluctance motor (SRM) combination with the high-performance permanent magnet material.

Through the two stages above, acidic substances in the oil would up to a certain concentration and start to produce polymerization reaction, form condensation and generate water, a neutral polymer resin and asphalt material.
The drafting of the code named "energy 20120491" oil phenol and amine antioxidants content determination method standard by Chinese Northeast Electric Power Research Institute, according to the American Society for testing and materials (US-ASTM), "Standard Test Method for published Measurement of Hindered Phenolicand Aromatic Amine Antioxidant Contentin Non-zinc Turbine Oilsby Linear Sweep Voltammetry" (ASTMD6971-2004) published in 2004[4], mainly describe a test method for determination of the contents of T501 and amine antioxidants oil by linear sweep voltammetry.
