Orthogonal Experiment Study on the Hydrogen Desorption Properties of NaAlH4 and LiAlH4 Zheng Xueping1, a, Feng Xin2,b , Lin Xiaobin AND Liu Shenglin3 School of Materials Science and Engineering, Chang’an University, Xi’an 710061, China aemail: zxp2004b@yahoo.com.cn, bemail: fixer308849846@yahoo,com.cn Keywords: Orthogonal experiment; NaAlH4; hydrogen desorption; ball-milling Abstract.
One of the most promising materials has been metal hydrides, but they have long suffered from poor hydrogen weight density.
The materials were characterized by pressure-composition-temperature (PCT) apparatus which can be operated up to 6 MPa and 400°C.

Amongst other works, his projects integrating kinetic structures e.g. include 'Ernsting Warehouse and Distribution Centre' (1985) and the 'Planetarium of the Valencia Science Centre' (1991).
This principle allows the reduction of input energy activating spring-back effects through bend-stiffening of the material.
The co-produced cavities for functional integrations of structural and sandwich materials, piping, smart sensing/wiring and mechanically responsive components are chances for the production of multivalent building envelopes.
Furthermore, activation of such smart elements may be optimized through additional introduction of ducts, cuttings, perforations and layering developing composite material characteristics.

Altering the Mn3+/Mn4+ ratio will affect the FM coupling which in turn affects the electrical conductivity of these types of materials [2].
La0.7Sr0.3MnO3 is one of the candidates for a good CMR material.
As stated by Feng et al., nickel substitution in La0.7Sr0.3Mn1-xNixO3 material decrease the metal-insulator transitions temperature and increases the overall resistivity [11].

In recent years, although many studies have been reported on the growth and characterization of the non-polar AlGaN materials [6, 7], the non-polar AlGaN epi-layers grown on sapphire substrates still suffer from a high density of threading dislocations (TDs) and basal stacking faults (BSFs) owing to the large lattice mismatch between AlGaN epi-layer and the sapphire substrate [8, 9].

Considering the anisotropy of the non-polar material, the strain between the quantum wells and barriers along the (1-100) m-direction and the (0001) c-direction could be respectively defined as:

By the knowledge of mechanics of materials, the bending moment of homogeneous elastic beam satisfies the following equation: (1.1) In the equation, stand for the curvature of retaining wall deformation curves, stand for the radius of curvature, stand for bending stiffness of retaining wall.
For homogeneous elastic beam, the bending stiffness could be determined accordingly when parameters like section size and strength of materials are given.
According to the mechanics of materials, Eq.1.4 can be further decomposed into: (1.8) In Eq.1.8: stand for distribution of load which retaining wall bear.
