The machinability coefficient of the materials can be calculated with the relation: Kpr=τrσr=RfRm (3) where: τr, Rf – the tangential mechanical stress to failure by stretching, respectively by shear; σr, Rm – the normal mechanical stress to failure by stretching, respectively by shear.
Conclusions This research provides further evidence that the optimization of unconventional technologies cannot be considered definitively completed, as long as there is progress in science and technology.
The results obtained confirm the conclusions of other research on the hybridization of ultrasonic and magnetic activation of the processing space by WEDM [9], [10], but bring important openings in terms of process monitoring and correlation of activation parameters, in relation to the particularities given by the processed materials. final quality.

The basic principles are sunlight penetrating the south glass of the building into the interior, absorbing solar energy by the dense materials such as brick, adobe, concrete and water, converting it to heat and using it fully and reasonably, thereby creating a comfortable indoor thermal environment.
The designer should also consider the regenerative properties of interior surface materials in residential house, the outer layer materials of interior surfaces (floor, ceiling, walls, furniture) should choose high heat storage materials, in the daytime with sunshine, absorbed some solar radiation and stored it, released it when lacking of direct sunlight, adjusted the indoor temperature, avoided excessive volatility.

Discussion on Preprocessing Technique of Geophysical Logging Data Huaping Yu1, a, Huan Wu2,b 1 College of Computer Science of Yangtze University, Jingzhou, China 2 College of Petroleum Engineering of China University Of Petroleum, Beijing ,China a yhpjz@126.com, b wjndxf@126.com Keywords: logging data; environment correction; normalization; interpolation; standard procedure Abstract: Logging data preprocessing is the basis of reservoir description and reservoir evaluation with logging data, which is a technique that can reduce the influence generated by the non–geological factors (such as the logging environment, logging instrument precision and calibration, the artificial operation etc.) as much as possible by some mathematic methods.
In principle, the first way is most effective way, but it takes a lot of manpower, material and time resources, and it unable to make full use of existing data; the second way refers to the use of high resolution processing on mathematical processing to improve the vertical resolution and radial resolution of logging curve, eliminate the influence factors of surrounding rock, borehole and mud, restore the true value of formation logging parameters [3].
