Introduction As the third-generation rare-earth permanent magnet material, Nd-Fe-B permanent magnet was developed in the 1980s with excellent magnetic properties and high cost-effective.Nd-Fe-B permanent magnetic materials have became an important material basis of new technologies,which ensure the wide application in electron, household appliances, military, medical equipments and motors, etc...[1].
For large amounts of Nd element and strong reactions, Nd-Fe-B permanent magnetic materials were easily oxidized.
Among all surface coatings, Ni-P alloy coating which possesses more excellent mechanical, magnetic and anticorrosion performance over the crystal materials may be one of the excellent.
The Ni-P alloy coating of ultrasonic electroplating was investigated in details.朗显示对应的拉丁字符的拼显示对应的拉丁字符的拼音 Experiment Materials and specification.

Cubic boron nitride(CBN) is of outstanding mechanical and physical properties,including high hardness and thermal conductivity.moreover,the thermal stability,chemical stability and resistance to oxidation of the CBN are better than diamond[2].These unique properties make CBN as an ideal cutting-tool candidate in processing of the hard-to-machine materials,such as alloy steel,quenched steel and cast iron[3].
The Method of the Experiment Sample Preparation The Laser cladding experiment with DL-HL-T5000B-CO2 industrial laser, clad materials is CBN powder, comparison of properties between CBN and diamond as shown in Table 1,substrate material is TC11 titanium alloy. make the cuboid sample through the wire cutting .The Chemical composition of TC11 as shown in Table 2.Before the experiment,TC11 cladding surface to be sanded and cleaned with acetone,using precoated method for laser cladding experiment.Use argon as the protective gas,the argon gas with a higher sputtering capabilities , does not have the chemical reaction with the metallic element.

However, the prerequisites for these good properties of mullite rollers are using high-purity synthetic raw materials and the firing temperatures far beyond 1580℃.
Experimental Procedure Raw Materials.
The chemical compositions of the raw materials were listed in Table 1 and the XRD pattern of the mullite roller waste was shown in Fig.1.
The roller wastes and other powder materials were mixed with the ratio: the molar of Al2O3/SiO2 is 3:2.

The BP neural network does not need the precise mathematical model, does not have any supposition request to the material itself.
Because has not considered the data hierarchy structure’s existence in this kind of material, the multiple linear regressions and the variance analysis cause to mistaken analysis for influential factors, and will draw the completely opposite conclusions [7-8].
And because the BP neural network model does not need to consider that whether covariate is independent, whether the strain capacity satisfies normal distribution and so on, in hospital expense and continual material, I suggested that we use the BP neural network model.

However, its inherent brittleness and high cost are the major limitation for large-scale commercial applications in packaging materials and textiles.
To improve the mechanical properties of thermoplastic aliphatic polyester, many strategies have been proposed such as copolymerization with other biodegradable polymers and blending with various materials (plasticizers or fillers, organic or inorganic) [1-7].
