The determination of material properties on permanent magnet brake In the Ansoft software environment, the model can have one or more material regions which are air, paramagnetic materials, conductive materials and permanent magnetic material.
When establishing the model, the area of each material should enter the appropriate material properties, and the material properties can be linear or non-linear.
The figure shows that the flux of brake mainly has three parts: First, the main magnetic flux which comes from permanent magnet and through the pole shoes, air gap to the track; this part produces the suction for brake, and its flux is maximum; Second, the leakage magnetic flux which through the interval of magnetic board; this magnetic flux is small because of the separators are non-magnetic materials; Third, the magnetic flux which comes from the end of pole shoe and through the surrounding air to reach the other end of pole shoe.

Recently, P(VDF-co-HFP) has received many special attentions as a promising material for polymer electrolytes because of its excellent properties [6-14].
Experimental Materials.
To estimate the compatibility of two materials, a single parameter, the relative energy difference (RED) is calculated from HSP of the two materials according to the following expressions.
A small RED value means a strong interaction or a good compatibility between the two materials.

The introduction With the development of the semiconductor laser, the absorption peak in 0.8 ~ 1.1 mu m band Yb3 + doped laser materials is becoming a hot spot of solid laser research at home and abroad.
In all the Yb3 + doped laser material, Yb: YAG laser material has excellent optical and thermodynamic properties and chemical stability, mechanical processing, and YAG cubic structure but also to produce sharp fluorspar spectral lines, to achieve high gain, low threshold laser operation [1-5] At present, the domestic Yb: YAG laser materials and laser research has not yet fully mature, through system research, access to quality, large size of Yb: YAG laser material, will advance to high solid laser beam quality, high efficiency, high power and integration, miniaturization direction.
Practice has proved that laser in such aspects as performance, reliability, and cost significantly better than that of Nd: YAG laser matrix materials [6].
