According to this, we had been observing J. mimosifolia whole year to study the growth and development law and the phenology of J. mimosifolia, especially the relationship between growth features and temperature humidity, aiming to provide theoretical basis for J. mimosifolia on disposing and landscaping of garden plants. 1 Materials and Methods 1.1 Test Material and Situation of Experimental Field J. mimosifolia of 55-year-old in Meishan Park of Neijiang were selected as test material.
The plants were introduced from Guangdong Province in 1956 by seed propagation and could complete the whole growth and development cycle without diseases and insect pests. 6 strains of them were selected as test materials, which were numbered N1～N6.

There is no correlation in BK 8 as 222Rn concentration is found to be independence to the environmental factors. 222Rn concentration in BK 8 could be influenced by building materials, ventilations and weathers.

And materials data integration and control are one of core competences concerning with the development of mass data application in manufacturing enterprises.
In this paper, a context-aware materials data integration meta model is presented which is incorporating an advanced materials demand mapping and decomposition mechanism to support fine-grained materials data in the right time for the provision of materials services, based on the analysis of the application context involving the key points and relationships in their manufacturing processes.
Materials Data Context-aware Model Proper Data modeling is an essential task for providing an efficient and effective representation of the phenomena of interest.
Actually, this is the mechanism for obtaining first-order context information from raw materials data.

With the adoption of surface modification method, microencapsulated phase change materials (MEPCM) with polyurea as wall materials, paraffin as core materials were successfully prepared.
Experimental Materials.
Therefore, we preliminarily consider that core materials have been coated by wall materials to form paraffin microcapsules.
Another reason for heat storage reduction may be that microcapsule consists of wall materials and core materials, and is active ingredient is inferior to that of pure phase change materials.

FEM Simulation and Experimental Results Effects of Material Thickness.
However, the increase of the material thickness and the decrease of hole-flange forming ratio, resulted the material was difficult to move downward.
The material thickness affected the bending feature and material stretching and these effects could be theoretically clarified on the basis of stress distribution analysis.
As the material thickness increased, the effects of bending feature and the material stretching increased resulted in the crack formation was easily generated.

Another accepted method of the composite materials manufacturing is the in situ synthesis method.
A considerable part of such materials are composite materials based on aluminum or its alloys with a unique combination of physical and mechanical properties [1, 2].
