The surface formation was main Quaternary, easy to lose circulation and the conventional plugging materials are no available.
After the processing agents for screening and research, the new materials meet the low permeability of coal bed methane drilling[7].
Conclusions Laboratory evaluation and application show that coalbed methane Fuzzy-Ball fluid, spot water drilling fluid, polymer drilling fluid and sealing with inert materials to match are different from each other.
Then add the recycling of inert materials to improve the drilling fluid density, effectively to balance the high pressure formation and to solve the coexistence of different pressure systems in the same hole.

Laser forming of sheet material has been widely investigated for the last 15 years.
The material used is stainless steel 304 of 1.04 ± 0.014 mm thickness with its chemical composition given in Table 1.
Practically, the start and end region of the last scan line is the place where the sample part stays attached to the base sheet material.
Acknowledgment Financial funding for this work was provided by the IWT, the Institute for the Promotion of Innovation by Science and Technology in Flanders.

Crops and their wild relatives are a reservoir of genetic diversity and provide the raw material for breeding new plant varieties, through classical breeding and biotechnological techniques, in response to environmental and demographic changes.
The science of modern plant breeding, including genetically modified organisms (GMOs) has allowed farmers to feed the world’s population except in cases of extreme climatic occurrences or political strife.
After examing large number of scientific reports it may be generalized that losses in plant material occurred in a specific order i.e. the highest in elite open pollinated cultivars of inbred lines.Among various categories of germplasm, wild germplasm and land races showed the highest genetic base of cultivated germplasm and or inbred line/hybrids (Fig 1) [4].

Abstract.
Significant differences between rural residential destruction due to construction location, structural types and different quality of materials used (1)buildings which built in the hillside and the peak have been more seriously damaged than ones in the flat terrain (2)Soil-wood structure, brick -wood house have been more seriously damaged than the brick-concrete ones.
(3)In remote rural, due to difficulties in transportation of materials, usually use local materials, choose local clay as wall materials.
And the immature soil wall can be mixed with artificial straw, straw, and some steel tie materials
