Different organic materials played different roles on morphologic transformation of Mn, fertilizers only led the fractions of Mn transform from low bio-availability to high bio-availability, which called active transformation[[] Sun H, Tan C Y, Huang D Y: Journal of Natural Science of Hunan Normal University. vol.34 (2011), p.82. ].
Different kinds of organic materials all increased the total Mn contents, Xie Z L explained that the total heavy metal contents was determined by the entrance and export of Cu and Zn in soil [[] Xie Z L, Zhu H S, Li W Y: Journal of Agro-Environment Science.

In order to improve management level of mining materials, optimum loading scheme is important.
The result shows that genetic algorithm in solving the optimum loading scheme of mining materials has quick convergence, short term, and higher precision.
Introduction In the mining enterprises, materials supply has many varieties, expensive and other significant characteristics, involving more than 30 kinds of million product such as building materials, machinery parts, equipment, explosive device, wood[1~2].
The paper solves loading problem of mining materials by genetic algorithm.

In the years passed since the first conference held in 1999 [1] the subject has expanded from isolated pioneering publications to one of the most actively developing trends in materials science and related disciplines such as materials processing technology, solid state physics and chemistry.
Recently the scope of NanoSPD was broadened to include further engineering and medical branches, thus increasing the number of publications in this field to several hundred per year and boasting top-cited papers in leading materials science journals [2].
As a resume of the scientific outcome of the conference, it was stated that bulk nanostructured materials produced by SPD have become an extensively pursued area of research in materials science.
In particular, the International Symposium on Ultrafine-Grained Materials moved its sessions on all aspects of science and technology of bulk ultrafine-grained materials produced by SPD techniques and other techniques.

Introduction J-integral in functionally graded material (FGM) is an important quantity of interest in material science.
Numerical simulation method has been developed for calculating the J-integral, for example, finite element method is a widely used to compute the J-integral in both homogeneous and nonhomogeneous materials.
By expanding the second integrand, (3) leads to . (4) Using equilibrium () and strain-displacement () conditions and noting that in homogeneous materials, the second integrand of Eq. (4) vanishes, yielding , (5) which is the classical domain form of the J-integral in homogeneous materials.
For nonhomogeous materials, even though the equilibrium and strain-displacement conditions are satisfied, the material gradient term of the second intgrand of (4) dose not vanish.
