There is a strong demand for precision machining of non-conducting materials.
This objective however, requires new brittle materials with high strength and high thermal resistance.
For brittle materials, the material removal rate increases with the grit size.

Materials and methods Materials The wild Paris polyphylla collected from East Lashan Grand Canyon in Baoxing county, Ya’an city, Sichuan province in April 2012 is identified as P. polyphylla var. chinensis (Fr.)
After the materials were taken out, wash away the dirt on the surface and remove the root, and then brush off the residual soil with a soft brush, soak the materials in detergent solution for 30min, and flush the material with running water for more than 2h for standby application.
Inoculate the materials of explants obtained to the induction medium.

Study on the Function of Steel Tube Concrete in the Fire Prevention DESHENG Zhu1,a, LEI Shi2,b 1Fire prevention division of Qingdao fire department, Qingdao, 266071, China 2School of Materials Science and Engineering, Shandong Jianzhu University, Fengming Road,  Jinan 250101,China aliukg163@163.com, deshzhu126@126.com, bslcqj@sdjzu.edu.cn Keywords: steel tube concrete; fire prevention; mechanical property Abstract: Using circumferential constraint action of steel tube to concrete, steel tube concrete makes concrete be in the condition of three-dimensional pressure, to increase the strength of concrete and enhance the plastic performance.
Due to the existence of the concrete could prevent or delay the steel tube from crippling, it makes steel tube material performance can be fulfilled.
Steel tube concrete can not only make up two materials their shortcomings, but also give full play to the advantages of both.
Second, due to the characteristics of mutual contribution, coordination and complementary, between steel tube and concrete which consist of steel tube concrete, when the temperature goes up, two kinds of materials work together, and take changes of load distribution caused by the temperature going up, which can play their excellent properties of two materials.
