Key words: Value Engineering, High Compression Ratio, Concrete Frame Column, Ductility, Longitudinal Reinforcement, Tie.
The principles of value engineering were adopted to analyze the major factors affecting the ductility of reinforced concrete frame columns.
Their importance can be evaluated by using 04 grading method in value engineering.
It is known from [4] that the direct cost of a reinforced concrete frame columns consists of materials, labor and equipment, and the material cost is much higher than the sum of the latter two so that the cost analysis of a reinforced concrete frame column can be simplified as the analysis of its material cost.

Micro-milling technology characterizing in high efficiency, high
flexibility and ability of processing complex three-dimensional shapes and a large variety of
materials, has now become a research focus in micro-mould manufacturing technology.
Because of this, reverse engineering (RE) for complex surface reconstruction has become the key technology.
PMMA is adopted as the workpiece material.

Abstract:Intelligent materials had been widely used in many fields such as medical, civil construction and aerospace fields, but in agricultural field, there were little applications reported.
In this paper, the basic concept, function and application of intelligent materials were introduced, some key problems such as knowledge base, reasoning machine were explained, at last, the application prospect of intelligent materials were analyzed. 1 Characteristic and application of intelligent materials Intelligent materials were new materials that emerged and developed rapidly in the world.
Then this will give these materials, structure the bionic function and make them “intelligent”, this type of materials were called intelligent material.

Keywords: Light emitting diodes, packaging materials, stamp tooling, cavity molding
Abstracts: The high power light emitting diodes unit internal structure was elaborated from materials and tooling point of view, the unit matrix frame layout for mass production was presented for copper sheet stamping.
The packaging materials and tooling was analyzed from the materials processes and automatic stamping & transfer molding.
The key for photonics transduction rate improvement is the lens molding materials and the phosphor powder selection and optimization [3, 4].
As the polymer materials, epoxy resin and silicon resin thermal conductivity is poor intrinsically, high conductivity coefficient materials, such as SiC, AlN, Al2O3, and SiO2, were added into the matrix to form higher thermal conductivity coefficient composite materials.

In order to improve the efficiency of the traditional building materials information management, a construction materials quality detection management system is designed and developed.
This system has been successfully used in certain Building Materials Quality Supervision Station, which proved that the development process is suitable for Building Materials Supervision Station to quickly establish construction materials quality detection management system.
As the requirement of state construction engineering quality gradually improving year by year, national building materials cycle is also shorter (usually only 3 to 4 years).
