Thisconcept is named “self-matching fuzzy ball plugging”[12].Rigid material and flexible material use their own intensityto form a “wall” to resist the fluid into the formation, whilethe fuzzy balls take advantage of the pressure, temperatureand passage shape of the losing formation and combinetheir own properties of high viscosity and deformability toprevent the fluid losing.

Simultaneously we also discover software itself some questions, which needs to carry on the revision and processing here. 2.1 Manual input parameter First we must carry on the definition to each components material attribute, which needs the manual input material performance parameter.
If in the following computation, there is no finite element analysis, then only the material density parameter is defined; otherwise, need to define the elasticity coefficient and the Poisson’s ratio; If there is heat transfer computation, then needs to define the material thermal conductivity and the linear expansion coefficient.
In order to simulate the whole hoisting process and include all motion process, we use super calculation equipment in Chinese Academy of Science Modern times Institute of physics.
At present, we use super computer at Chinese Academy of Science's Modern times Institute of physics to calculate the equipment, through the external cooperation, and have already solve the integrity computation of tower equipment hoisting process, including the steel wire, the crane, the tower equipment.

Building churches beyond the Great Wall, even in Gothic style, obliged the missionaries to encounter the Chinese workers, construction methods, and buildings materials.
Furthermore, a great diversity of churches was built, of which the size, the style and the materials varied according to the function and the period.
Le Missionnaire Constructeur mentions that the different degree of slopes depending on the covering materials.
There were also churches covered by stone slates.[ During fieldwork in 2011, we have seen some remains at the church of Shuangshizi: hexagonal slates, 55 x 30 m, 0.80 cm thick. ] Materials, Craftsmen and Tools.

The main relevant difference with the classical materials consists of the increased value of the “a” exponent (a » 0.40).
The deformation was produced by the martensitic transformation, instead of a glide dislocation as in standard materials.
Therefore, less dislocations are expected to be created when cycling SMA materials at low levels of deformation (i.e., near 1 %) and stress (about 200 MPa), thus giving comparatively a longer life.

Introduction Calcium carbonate is a field of fine chemistry as domestic natural resources enhancing effective use of raw materials and added value in chemical industry.
In this study, the optimum experimental condition of electric conductivity, pH and reaction temperature were examined closely utilizing a carbonation process using Ca(OH)2 and CO2(g) as starting materials, while a reproductivity experiment was also conducted.
Experimental Procedure As starting materials for the experiment, 95% of Ca(OH)2[SIGMA] and 99.9% of CO2(g) were employed.
