Fig.3 The radial basis function neuron of having R dimension input
This paper chooses Guass function as radial basis function,for the radial basis layer neuron ,it uses the vector distance of neuron j’s weight vector and input vector to multiply by the deviation bj,and uses the product as basis function’s input.The mathematical expression of radial basis neuron j’s input is :
,=1,2...R (4)
The mathematical expression of radial basis neuron j’s output is:
, (5)
With the reduction of the distance of and ,radial basis function’s output value will increase;When the distance of and is 0,that is when the weight vector eaquls to the input vector ,the radial basis function’s input is 0,and the maximum outuput is 1.
Testing result.The calculated results of three experiments are 0.778L,0.782L and 0.791L,the average value is 0.784L,so the error is 2.04%.Then input the data into MATLAB for three-dimensional restoration,and compare with the actual material stack,the calculated result is close to the reality,so the accuracy is satisfied with the actual need.

It can be concluded that ASV, applying the portable metal analyzer, together with the standard addition method is certainly a valid analytical method (good selectivity and, especially, sensitivity, data omitted) for determining the four metal elements having very similar half-wave potentials.
When Cu(II) was added, the formation of the Cu-Zn intermetallic compound caused reduction in the Zn(II) peak (first ~3%, second ~17%, third ~13%, respectively).

These were found by processing of experimental data and by direct dimensional analysis using the Buckingham's π-theorem [10,11].
Than the value of is higher, so much greater is the contribution Ii of ions in the total current I, but this leads to the reduction of partial current Ip transmitted by separate particles (I = Ii + Ip = const) and the electro-separation process being less effective.

The crystallization behavior of the glass in the
ZrO2-ZnO-Al2O3-SiO2 system was also been investigated to provide useful data for further research.�
Materials and Methods
The glass was prepared from reagent grade SiO2, Al(OH)3, ZnO, ZrO2, K2CO3 and Sb2O3.
This causes the reduction of the value of Vickers microhardness of the glass ceramic.

That is of significance and valuable to those subjects of investigation of strength of coal seam in deep underground and mechanism of propagation and coalescence and evolvement of crack for coal seam in deep underground, it is shown by numerical simulation that failure shape of coal seam in deep underground under triaxial compressive experiment of lateral pressure of 25Mpa is typically shear failure, and characteristic of deformation is obviously elastic-brittle, which is significance to understand the performance of the coal seam in deep underground
Introduction
I For many years, many scientists analyze data of global weather and founded that global climate has becoming warming and those changes are relevant with atmosphere greenhouse effect,If emission in atmosphere is not controlled effectively, global average temperature will continue becoming higher.
Captured in the atomospher is injected into coal seam, its immediate significance is reduction of greenhouse gases emission in the atomospher, there are also indirect significance, Fist injection into coal seam can enhanced coal bed methane recovery, injection into coal seam can not only reduce greenhouse gases emission and but also enhance coal bed methane recovery, which is very importent significance.
