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.

The theory of pyrolysis Nowadays, the pyrolysis method of waste materials has become one of the most popular disposal methods.
As the higher temperature, the main chains are turns to split and form many materials at small molecular weight.
The gas produced after pyrolysis, once being cool, can be departed into flammable gas and liquid tar which can be collected through the outlet water while, the solid materials produced after reaction are the waste carbon (mainly is the coke and inorganic content).
At the basis of satisfying the technology request and function, by combining the theoretical drying area and pyrolysis area and named its volume at 0.4m3 we can achieve the input materials at 100kg once, then up to the 1t each 24 hours.
When designing this furnance, we take reference of the experiences both the country and outside, meanwhile, considering the technology, materials.

Introduction The shape memory alloys (SMA) represent a class of metallic materials with particular thermo-mechanical and electrical properties, high power density and ability of producing comparatively large actuation strains/stresses [1].
One is the characterization of the thermo-mechanical behavior of SMA materials [5] and the other is the actuator application of one-way shape memory effect (SME).
SMA material has an high electrical resistance, it can be heated to its transition temperature simply by passing current through it.
Different functions can need different materials and different physical connections.

Introduction The aiming for improved heat sink materials exhibiting highest thermal conductivities at tailored coefficients of thermal expansion motivates the search for improved composite materials and for improved interfaces between any matrix and highly conductive inclusion phases.
Experimental The method used for the roughening of the original smooth surface of the diamonds comprises the mixture of the respective diamond powders (Qiming Superabrasive Materials, Henan, China) with fine Fe-, or Mn-powders (BASF carbonyl iron powder CN, Mn-powder: Merck) at a weight ratio of diamond:metal = 1:1 followed by a heat treatment under inert (Ar gas or N2) or reducing gasatmospheres (H2 gas) in a muffle furnace.
