Biological catalysis method to prepare L-tert-leucine, need inorganic ammonium as auxiliary raw material [5], the reaction of inorganic ammonium and derivatization reagent forms fluorescent derivatives [4], retention time of it and L-tert-leucine derivatives are nearly the same, which affect the detection of L-tert-leucine seriously, so it is not suitable for the L-ter-leucine to determine by derivative method in the enzyme catalytic reaction system.

To fully understand and predict the mechanical behavior of bones, not only the mechanical characteristics but also the morphological characteristics should be investigated, because bone tissues are a porous composite material.
Materials and Methods The 12 th thoracic vertebrae were obtained from 85 years female and 48 years male cadavers and these were immediately kept in freezer at -25�.
For the material properties of vertebral trabecular bone in the FE models, the Young's modulus of 10� and the poisson's ratio of 0.3 [1] were utilized.
The material property for the FE analysis was considered to be isotropic and displacement boundary conditions were applied to the specimens to simulate a uniaxial compression test using ABAQUS6.4 (HKS INC., USA).

Ferris, Jr. drew a decay curve for different band waves that penetrated walls with different materials [12].
The wall materials included concrete walls, brick, clay, glass, wood, and cardboard.
It should be noted that the wall material made a significant difference in results.

Such materials include a-Zr and a-Zr based alloys employed in the nuclear energetic [1].
Detailed studies of regular evolution of material dislocation substructure were carried out for FCC and BCC materials [2].
The plastic deformation processes in polycrystalline and structurally inhomogeneous materials is frequently addressed in terms of GND.
