This paper introduces the basic methods of corrosion prediction for the materials in natural environment.
Materials corrosion prediction can speculate the long-term corrosion behavior using a short term corrosion data, speculate corrosion behavior of large samples based on small samples and speculate the materials corrosion in actual environmental with the simple condition indoor corrosion data.

In our numerical simulation, the emphases is the process for formation of fracture saturation in multilayer materials , we note that failure phenomena depend very strongly on the properties of the materials disorder and thus the involved material can not be treated as a homogeneous medium.
Our numerical simulation recurrence the phenomenon of fracture saturation in multilayer materials.

Pre-Treatment of Vegetable Waste in the Production of Composite Materials Ruslan R.
Currently, the use of technogenic raw materials, including wood waste is one of the trends in manufacturing of building materials.
This is due to the limited resources, the need for long-distance transportation, the high material and energy cost of some technological processes of raw materials extraction and processing.
All of them greatly hamper the development of the industry of building materials based on natural resources.
The currently produced wood-mineral composite materials are widely used in the construction, but have several drawbacks.

These types of structures are classified like composite materials with polymeric fiber matrix and in this field of activity are not many investigations.
In order to develop a more advanced model it is necessary of a multidisciplinary research group in order to combine the most advanced sciences at his moment, like: composite materials, textiles - microfibers, chemistry and also mechanical science.

Commonly used adsorbents include natural waste such as carbon-based materials, diatomaceous earth, fly ash, and sawdust.
However, there have been no reports on the oil absorption and regeneration performance of EG oil absorbing materials based on commercial expandable graphite, which is not conducive to the large-scale practical application of EG oil absorbing materials.
Simply put 50 ml of oil materials in a beaker, and then about 0.1 g of EG is weighed and poured into the oil and stirred to stand.

Effect of dynamic change of activities of enzymatic in Sugarcane field with different coating material wei-sheng Shi 1, a, hai-ming Liu, zheng Peng, yu-shu He and fu-jie Zhang 1 Faculty of Modern Agriculture Engineering, Journal of Kunming University of Science and Technology, Kunming 650500,China a shiweisheng888@sina.com Key words: coated material ; activities of enzymatic; dynamic change; Abstract: the effect of dynamic change activities of enzymatic in Sugarcane field with different coating material was studied With three kinds of coated compound fertilizer as raw materials.
In such an environment, the coated compound fertilizer as raw materials of the Idesia polycarpa var.vestita oil can induce the soil enzymatic activities of sucrase more effectively than the coated compound fertilizer as raw materials of polyolefins.
