Even if energy calculations or tabular data are stipulated, both meaningfulness and impact on the jury decision seem to be highly doubtful.
Major steps toward reduction of emissions and energy consumption need to be conducted in early design stages.
Ranking comparison between jury ranking, key performance data, and student’s subjective evaluation.
To find out, if gender or being a graduate or undergraduate student changes the average evaluation significantly, the collected survey data was clustered by these attributes.
Future Research should focus on fine-tuning of the subjective evaluation criteria, and encompass a larger data sample of different competitions.

For example, partial heating of the joining partners should result in a reduction of the process time.
Finally, due to the real tests and the use of the finite-element method, not only a reduction of the process time due to preheating could be confirmed, but also the use of the simulation software for the design of friction welding components could be proven.

Combining chemical environment analysis with the effective minority lifetime data, the effect of the surface conditions on the Al2O3 films passivation was discussed.
The recombination losses reduction at a semiconductor surface with Al2O3 passivation films can be attribute to strong field-effect passivation as well as excellent chemical passivation [2-4].

The results had significant application on tannery wastewater treatment with great reduction of pollution.
The average generation time of bacteria based on compound salt NaCl:Na2SO4 4:1 3:2 2:3 1:4 T/min 30.8 33.4 35.8 39.7 The data in Tab.3 showed that under the condition of pure salt, the average generation time of bacteria increased while the concentration of NaCl increased; it indicated that with the salinity increasing, the influence of salt on the average generation time of bacteria increased.
The relation between salinity of tannery wastewater and the generation time of bacteria under the condition of compound salt could be obtained by correction Eq. (9): (14) According to Eq.(10) and the data in Tab.4 , it could be obtained that KNaCl:KNa2SO4≈1:3.
The total salt concentration of actual tannery wastewater was about 5g/L,it could be calculated that KNaCl:K'≈1:2 according to the average generation time of bacteria estimated 34min and the data were in Tab.3.

The viscosity of ployacryamide(PAM) solution is measured by CVRO200 rheometer under low shear rate after different shear time.The results show that the viscosity of PAM solution having the same concentration and hydrolysis degree increases with the molecular weight increasing.The viscosity of ionic PAM solution is far more than that of non-ionic PAM in the case of the same mass concentration.The viscosity of PAM solution decreases significantly with the brine salinity increasing,and ionic PAM is influenced much more seriously than the non-ionic PAM.An increase in temperature and the concentration of sodium hydroxide causes a great reduction of the viscosity of PAM solution,and non-ionic surfactant can lower the viscosity of PAM solution,but the impact is not very serious.Moreover the viscosity of PAM solution reduces obviously with the increase of shear rate and shear time.At the same time,the relevant theoretical interpretation is given.All these might serve definite purpose for the study
The comparison of Table 3 with Table 1 and Table 2 obviously shows that the viscosity of ionic PAM solution is much larger than that of nonionic PAM solution at the same concentration.It is the structure of polymer in solution that results into the difference.The ionic PAM molecule in solution is charged which make the polymer molecule in the stretch state,but the nonionic polymer almost displays crimple state.Data in Table 3 show that molecular weight and viscosity of the polymer reduce as the shear time increases.So if we want to obtain anticipated viscosity of polymer solution,small amount of higher molecular weight polymer is economically superior to relatively large amount of lower molecular weight polymer[2].
Data in Table 4 shows that the difference of the viscosity of polymer in different shear time between the saltness of 30 g/L and without any sodium chloride at a constant shear rate,and the influence of sodium chloride on the polymer viscosity is considerably serious,which makes its viscosity reduce greatly.Because of the increase of salinity,the electrical repulsion force of carboxylate ions on the polymer is shielded,and the size of molecule crimped and decreased,which leaded to the decrease of polymer viscosity[3].
Data in Table 5 shows that the influence of the saltness on the viscosity of polymer solution becomes weaker and weaker.The comparison between table 4 and table 5 indicates that the influence of sodium chloride on the ionic PAM solution is more serious than that of nonionic PAM solution.The main reason is probably attributed to the difference of their hydrolytic molecular structure.Mechanism analysis of above-mentioned results can be explained as follows:In the solution of the partially hydrolyzed PAM,sodion in the sodium acetate group ionizes makes the group electron-negative.The mutual repulsion of acetate ion in the polymer makes the high molecule chain extended,and the size of the molecule is relatively large which makes both the flow resistance and the viscosity of the polymer solution increase.when the salinity increases,the sodium ion accumulates around the group of acetate ion and weakens the function of the negative ion,thus the mutual repulsion function of acetate ion weakens,
