But in practical machining, it is hard to get the parameters by this way because of the different machine tools, different cutting tool and different materials.
The empirical formula of the life of the drill [1]: (m/s) (1) Where, Cv ——coefficient (which is related with drilling materials and feed ); T——life of drill(s); z, m, y——Index(which is the influence of d, T, f ); Kv——correction factor of cutting speed.

A model shows a system with simultaneous resin infusion from the inside and outside of the material.
Microscopic images of a slice from a part made with simultaneous resin infusion from the inside and outside of the reinforcement material.
In contrast, Figure 7 shows that resin impregnation via the guide sleeves resulted in relatively defect-free material.

This kind of fertilizers is prepared by granules of conventional fertilizer with various materials coated.
The release and dissolution rate of water-soluble fertilizer can be directly affected by the coating materials.
For some kinds of polymer coating materials, it takes a long time to degrade and they will cause a soil secondary pollution.

Optical Properties of Water-soluble Er-doped ZnS Quantum Dots Synthesized by a Hydrothermal Process Gang Li1, a, LiHua Li1,b, LiuShuan Yang1,c , JinLiang Huang1,d 1Department of Material Science and Engineering, Henan University of Science and Technology, Luoyang 471023,China alg337811663@163.com,blilihua7818@163.com,cliushuan@hncj.edu.cn,dhuangjl@haust.edu.cn Keywords: Er-doped ZnS; Quantum dots; hydrothermal process; Luminescence properties Abstract.
QDs are recognized as ideal ultrasensitive, multicolor and multicomponent fluorescent labeled probes due to their bright, photostable and color-tunable fluorescence characteristics.The most vestigated quantum dots (QDs) are usually cadmium-based materials, such as CdSe, CdTe, and CdS QDs [7-9].
ZnS is one of the important II-VI semiconductor materials.
Rare earth complexes became excellent luminescence materials, as lanthanide ions with peculiar characteristics.

The majority of SOFC development to date focuses on electrolyte-supported cells (ESCs), cathode-supported cells (CSCs), or anode-supported cells (ASCs), whose mechanical supports are brittle ceramic or cermet, and contains expensive materials.
Operation of the SOFC at a reduced temperature can overcome some of these problems and bring additional benefits, such as low cost materials, rapid start-up, and low corrosion rate.

The mechanism of material deformation is very similar for ECAE and orthogonal cutting process.
Conclusion A general streamline model was used to study the material flow in the primary shear zone.
The results showed that the streamline model presented in this paper is available in investigating the material flow in Metal Cutting.
