Some countries control the price of global bio-energy raw materials [10], and manipulate the international raw materials market.
It not only increases the food production, but also provides rich raw materials for bio-energy development.
There are plenty of trees and flowers for urban greening and a large number of biomass materials.
If the materials developed reasonably, abundant raw materials and fertilizers would be provided for the development of bio-energy and circular agriculture, and that will have a wide prospect for development.

Poor style construction and temporary structures will be updated.Secondly, the walls will be refurbished, the wall materials will be restored, the existing coating paint will be removed.
The vertical projection billboards and shop front are advocated, the advertising materials are used in coordination with construction.
The third is to expand the width of sidewalk, change the material, and to use the neat green flagstone., and then to open up the street parking.

It is surmised from Eqs. (4)-(5) that the material removal rate depends only on r if parameters L, W, W1, and p are kept constant, indicating that the material removal is different at different working points.
It is obvious that the parameter W would affect the uniformity of material removal, (W), strongly in some ranges of W.
The results indicated that although as the parameter W increases the material removal increases monotonously, the parameter W should be setup at a range of 0.9-6 for improving the uniformity of material removal.

Illustrative Example There is a mobile phone enterprise which designs and products packaging materials for many type of handsets.
The development of the mobile phone packaging materials needs three enterprises cooperation: the supplier A designs and manufactures the packaging materials mold, the supplier B completes the proofing, the mobile phone enterprise designs the packaging materials and accepts the packaging material and mold.
We suppose there are three development projects to mobile phone packaging materials.
The project development process is presented as following: Designing packaging materials→Manufacturing mold→Proofing→acceptance of packaging material and mold.
The multi-project collaboration planning for design and manufacture of mobile phone packaging materials Here, ID1, ID2, ID3, ID4 are used to represent designing packaging materials task type, manufacturing mold task type, proofing task type and acceptance of packaging material and mold task type.

Experiment Methods Experiment materials.
By the way, the tensile strength of Nickel-plating CNTs reinforced composite is higher than the CNTs reinforced composite's, which shows that the plating CNTs can strengthen the composite materials obviously.
This also can infer that the dispersion and the binding between the CNTs and the matrix are the key factors to strengthen the composite materials.
b) Further research on the material microstructure, especially the interface properties of the matrix and the reinforced phase, and find out the relation between microstructure of materials and mechanical properties.

Introduction Glass-ceramics are polycrystalline materials containing residual glassy phase, obtained from glasses subjected to controlled crystallization. [1, 2] This definition is related to the glass-ceramic materials obtained through glass technology (melting).
Materials and experimental procedures A batch of glass composition 9.56Li2O.22.36ZrO2.68.08SiO2 (wt.%) was prepared from commercially available raw materials (Li2CO3, ZrSiO4 and quartz).The batch to produce 2 kg of glass was introduced into a Pt crucible and melted at 1550 ± 5°C in an electric furnace for 7 h.
In fact, according to Strnad (1986) [2] glass-ceramic materials have bending strength between 70 and 320 MPa while high alumina ceramics between 212 and 353 MPa.
