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.

An experimental analysis of interior noise in an ambulance and noise reduction with damping materials BAI Song a, XU Xinxi b,*, YANG Meng c, LIU Xiaohui d, Su Weihua e, NIU Fu f (Institute of Medical Equipment, Academy of Military Medical Sciences, Tianjin 300161, China) asoon169@163.com, b xuxx1@sohu.com, cyangmeng@163.com, dliuxiaohui@163.com, edirectorsu@126.com, fniufu@163.com Keywords: vibration; vehicle interior noise; partial coherence analysis; panel acoustic contribution analysis (PACA); noise reduction with damping materials.
On the basis of analysis, the structural modification with damping materials is performed on the panels with greater contribution.
Figure 5 shows the panels covered with damping materials.
Additionally, comparing with the condition of covering damping materials layer at all panels, the added mass of the condition of partial covering damping materials layers at panels is 38.4kg, saving 24 kg.

Investigation of a Mode III Crack in Functionally Graded Magnetoelectroelastic Materials B.
Introduction Functionally graded materials are inhomogeneous materials in which the material properties vary continuously in one or more directions.
It is important to study the properties of functionally graded magnetoelectroelastic materials to have a better understanding of these materials under different conditions.

The problem following is that process brings too much unrecycle talc paper plate leftover materials when the talc paper plate is cut out and molding.
Those leftover materials always be abandoned as crab.
Different concentrations of immersion materials indicate the same variation rule.
Influence of immersion concentration Figure2 indicates that decomposition rate increases as concentration of immersion materials increases, but the variation amplitude is less.
