The Concept and Characteristics of Mineral Resources Mineral resources have the characteristics of natural materials that objectively exist, at the same time have social, economic, political, and even military characteristics due to human’s gradual recognition of their natural characteristics.
The biggest difference between resources and resources assets is that the former focuses more on goods and materials with useful value, while the latter more on prospective earnings based on resources control, thus the latter has more economic and legal meanings.
Mining capital twice makes its appearances among mining sanzi: at the first time, the combination of capital and mineral resources makes mining resources-assets, and transforms mineral resources into production materials; at the second time, the combination of capital and mining resources-assets promotes the development and utilization of mineral resources and associate social resources.

However, oil production need a lot of biomass materials.
Biomass species fall into two broad categories [8, 9]: one is various kinds of biomass materials from industrial production and agricultural residues; another is energy crops from artificial cultivation.
Biomass materials from industrial production have advantage of huge quantity, concentrated distribution and local use of producing biomass fuels saves transportation cost.
Therefore, industrial residues as biomass materials to produce oil are one of novel areas in biomass utilization.

Very interestingly, beyond the doped semiconductor layers, the metallic and dielectric materials in the gate regions are also distinguished.
Therefore, the sMIM mode allows to analyze the local electrical properties of a large range of materials, independently on their electronic character.

Materials and methods Selection of fruit.
Small molecule like sucrose, fructose and glucose were also highly hydrophilic and soluble but their molecular weights were smaller than the polymer materials.
In another word, there were different water content combined with different macromolecular materials.
