The results show that with the increasing of hardness of 45 steel,its wearing resistance increases considerably when hardness of abrasive(Ha) is higher than hardness of 45 steel(Hm),however,it varys very slowly for Ha
74 signals of two types of vehicle collected on road in situ were analyzed. The results show that it is feasible to realize the automatic vehicle classification by the features of radiated noise extracted by the AR model,and the correctness rate of the classification is higher than 80%.
The HTGR supercritical (SC) steam cycle plant coupling the existing technologies of the current HTGR design with operational experiences of the SC fossil power plant (FPP) will achieve high cycle efficiency, 45% and above,which is 30% higher than that of the existing PWR plants (with net efficiency of 33%).
Results The iron content for feridex PLL labeling group was higher than for the control group (P<0.05). In the feridex PLL groups, the iron content of the 25ug/ml group was higher than of the 10ug/ml or below groups (P<0.05), but not lower than of the 50ug/ml or above groups.
②The infective rate of HBV and the carrying rate of HBsAg in the PHC group were both significantly higher than those in the non-PHC group and health check-up group (P<0.005), the relative risk(RR) both exceeded 1, and the attributable risk percentage (AR%) was all about or over 75%;
When electrolysis temperature changed in 720℃~780 ℃ , the current efficiency increased with raising of the electrolysis temperature, the highest was 81.3%. However, the current efficiency was reduced if the temperature was higher than 780 ℃ .
