The fuel of forest biomass power generation belongs to forest biomass material, thus makes much lower emission of SO2 and NOX, and creates almost zero emission of CO.
Furthermore, forest biomass material belongs to renewable energy, consequently, its emission and absorption of CO2 constitutes nature carbon cycling.If we do not take the CO2 emission from the acquisition and transportation links into account, its energy utilization can achieve the zero emission of CO2 , even negative emission.
At present, fire coals is the major materials for thermal power generation in China.
There is tremendous diversity of resources advantages among different regions in the vast China, thus the choice of form of clean energy power generation mainly depends on the local resource endowment and has little relation with environmental cost (it will create low environmental cost in all forms of clean energy power generation).Compared with other forms of power generation (especially the nuclear energy power generation),the forest biomass power generation has the advantages of the low risks, relatively simple devices, technology easy to be popularized and spread, and relatively cheaper materials.

The conversions of the thermal conductivity to design values can be done using the following formulas:
FT=efTT2-T1 (1)
Fm=efψψ2-ψ1 (2)
λ2=λ1∙FT∙Fm∙Fa [W·m-1·K-1] (3)
where FT, Fm are the conversion factors of temperature, moisture and ageing. fT is the temperature conversion coefficient, fψ is the moisture conversion coefficient volume by volume which values are specific to the materials.

When it comes to detecting physical signals, as body pressure, carbon-based materials are an adequate resource, mainly due to their thermal and mechanical properties, along with their piezoresistive behavior, that is, the ability to change its electrical resistance from a mechanical deformation.
Among these, graphene nanoplatelets (GNPs) have a more affordable price when compared to other carbon-based materials, making it more applicable on an industrial scale [6, 7].
Plasma treatment is a surface treatment of different materials that takes place from the equal discharge of positively and negatively charged particles [11].
Experimental Materials and methods Materials.
It is also possible to observe an increase in roughness in the samples that received the corrosion treatment with NaOH, due to the extraction of low molecular weight materials and the presence of lignin in them [15].

Moreover, there we do not
recognise an exchanging of materials there.
Let us remind that this way permits an approximation of materials by parameters and processes by interactions of them.
It was proofed that development and especially reproduction requires parameters (materials) capable of interaction with other parameters in different ways which cannot be expected from non-organic materials, but we can hope for this in organic ones.
In it we can expect to define necessary and sufficient conditions for development and reproduction irrespective of concrete processes and materials.
