Comparison of Measurement Methods to Acquire the Steel Tubes Characteristics IVAN Buranský1,a, EVA Buranská2,b 1,2Slovak University of Technology in Bratislava, Faculty of Materials Science and Technology in Trnava, Institute of Production Technologies, Jána Bottu 25, Trnava 91724, Slovak Republic aivan.buransky@stuba.sk, beva.buranska@stuba.sk Keywords: computed tomography, CMM, 3D optical scanner, steel drawing tubes Abstract.
The data acquisition is limited by wall thickness and material density and that is disadvantage.
Since 1980, CT became popular for material analysis and non-destructive testing (NDT): e.g. for observing the inner structure of materials (e.g. fiber-reinforced plastics) and detecting material defects.
Hence, qualitative statements on material defects can be made.

The analysis shows that: in comparison with coal-fired generation, wind power generation saves more energy and reduces emissions of pollutants markedly; the main energy consumption comes from production of raw materials, which takes 79.3% of the total energy consumption throughout the life cycle.
The target of this study is to analyze energy consumption and pollutant discharge quantitatively, calculate energy repayment time and clarify critical energy-consume processes about wind power generation including production of raw turbine materials, turbines manufacture and build-operate-scrap process of wind plants.
According to material composition of every subpart, energy consumption and environmental emission of producing one-ton principal raw materials (Table 1), total energy consumption and environmental emission in manufacture stage (Table 2) of wind power generation can be calculated.

NPEs are synthetic detergents main raw materials, very extensive.
Qiao, etc’s research [21], the survey results of sludge samples from 4 wastewater treatment plants were all detected NP kind material, and the concentration range in 1~ 128 mg/kg for three consecutive years since 2003.
The sludge was placed under 5 kGY of 60Co-ray irradiation in 24 hours, the sludge easily degradable organic matter content of contaminants was in the increase, and refractory material was reduced.
