In this way, a substantial burden will be increase to the farmers, so we can take other ways to offset the farmers , such as reducing the price of seed, fertilizer and other production materials through industrialization and related policies ,and granting financial subsidies to farmers as compensation[4]

In electrical discharge machining (EDM), an electrical discharge occurs between a tool electrode and a work-piece, and removal of materials is carried out by vaporized explosion between the electrode and the work-piece.
However, the mechanism of material removal in EDM is not well understood.
However, the mechanism of material removal in EDM has not been fully clarified.

Effects of Carbon Nanotubes Incorporation on the Grain Growth and Properties of WC/Co Nanocomposites Faming Zhang 1, a, Jianfei Sun b and Jun Shen c 1 School of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, P.R.China a faming.zhang@hit.edu.cn, bjfsun_hit@263.net, cjunshen@public.hr.hl.cn Keywords: Carbon nanotubes, Nanocomposites, WC/Co, Grain growth, Mechanical Properties.
Carbon nanotubes (CNTs) combining unique mechanical and physical properties could offer a kind of nanosized reinforcements for composite materials.
Introduction Carbon nanotubes (CNTs) have attracted remarkable attention as the ultimate nanosized reinforcement for composite materials because of their exceptional mechanical, thermal and electronic properties [1].
It could be drawn that CNTs have not changed into other types of carbon materials, e.g. graphite, diamond etc. and can be used as reinforcements in spark plasma sintering process.

In certain developing nations, vast amounts of the leftover straw are burned in the fields or by the side of the road instead of being employed as industrial raw materials.
The raw materials utilized in this study were characterized by their environmentally-friendly properties and low cost.
Moreover, the employment of these materials in the process of oil-water separation demonstrated a highly successful waste management approach.
Experimental Materials: The AR grade of sodium hydroxide (NaOH) was procured from RCI Labscan Thailand.
FT-IR spectra of rice straw before and after boiling with NaOH solution, oil absorbent materials were prepared using 20, 30 and 40 g of rice straw.

Experiments Materials and Preparations.The Partial Y2O3 stabilized ZrO2coatings are METCO powders using an atmospheric arc plasma system equipped with an F4 plasmatron (Sulzer Metco) onto Al-based alloy substrates with a length of 150mm, width of 100mm and thickness of 10mm.
