Expression characteristics of the model as a full feature information, and can reflect the correlation between the characteristics and the processing characteristics, including the geometric properties of each feature type, attribute accuracy, material heat treatment, the relationship between the properties and technical parameters required attribute information.
Wherein the characteristic information includes the geometry and dimensions of the geometry, such as the surface shape, the mutual position between the surfaces, dimensions and tolerances; also known as non-geometric information is the information technology rough features, parts, materials, processing accuracy, surface roughness, heat treatment , surface treatment, and engagement with relations and the corresponding technical requirements, this information is necessary for the formulation process.

Crystal growth control system block diagram Cadmium Zinc Tellurium Crystal Growth Principle By material science know CdZnTe Crystal melting point higher, its melting point values is in connection with CdZnTe three materials ratio; for example, Te Zn0.04 Cd0.96, Crystal melting point is 1095 ℃[1].
In order to guarantee that the tellurium zinc cadmium material interior elevation of temperature is even, the elevation of temperature process uses the curve control to make it to elevate temperature slowly.

That means the material removal can be controlled by selective deliquescence on the convex.
Consequently, the material removal ratio is directly proportional to pressure and fluid flow, as shown in Fig. 3 and Fig. 4.

Introduction Increased requirements for safety and performance of structural elements operating in difficult conditions, lead to the necessity of their manufacture from the most perspective materials.
Often the existence of desired structure is achieved by cooling of the material at a predetermined velocity [1].
The material properties of the billet is a functions of temperature Ts.
