Applications of Specific Forms in Modelling Design of Industrial Product Shape is mainly refers to outside basic shape of the product that corresponds to the contents or materials, and have characteristics of generalization and abstract.
Because, compared to rectangle, it is Specific forms and has strong contrast of quadrate and roundness, so on the modelling by combining different rectangles the huge disc is very outstanding which not only constructs the aesthetic characteristics of product modeling, but also strengthen the sense of science and technology of the machine tool.
The characteristics of square geometry totally different from ripple shape existing in the same continuous shape that reflects not only the continuation of same material but also the continuation of same shape .We can't split the shape into two separate parts，because they are in fact in a material entity that has the shape with some different local shapes.

Material balance equation of water-drive gas reservoir is pZ[1-Cp+SwcCw1-Swc∆p-We-WpBwGBgi]=piZi(1-GpG) （3） Water storage coefficient ω is defined as ω=We-WpBwGBgi （4） Dimensionless pressure PFD is defined as PFD=pZpiZi （5） Neglecting expansion energy of rock and irreducible water, material balance equation of water-drive gas reservoir is PFD=1-Rg1-ω （6） If gas reservoir is closed, water storage coefficient ω is equal to 0, the relationship curve between dimensionless pressure PFD and gas recovery degree Rg is a diagonal line.
There are two fundamental equations in this method, the first is production index equation of water layer qe=J(p-p) （13） The second is material balance equation of water layer supposing formation water compressibility factor is constant.
According to material balance equation of water-drive gas reservoir (Eq. 3), PH pressure is defined as PH=pZ[1-Cp+SwcCw1-Swc∆p-We-WpBwGBgi] （19） Corresponding value in extension line of initial PF line segment is target value of PH.

Introduction In recent years, with science and technology’s development, neural net was taken account of in the field of predicting properties of material.
Constitutive relationship of metallic rubber was related to density of material, more importantly, related to shape factor of the material in the documents [3~5].
In this paper, coefficients of constitutive relationship of the material in the two conditions that were only different shape factor, different density and shape factor respectively were trained and studied by BP neural net.
