These data demonstrated that the addition of Y2O3 could not increased the amount of Al4SiC4.
The first step begins with the reduction between Y2O3 and A12O3 particles, which is shown as: 2Y2O3(s)+ A12O3(s) = Y4Al2O9(s)(YAM)

More than ten years later, rubber tracks were studied in China, and even completed a batch production. 1.3 The function of the composite elastomer Rubber track is composed of four major parts: metal core components, strength layer, buffer layer and rubber composite elastomer.The rubber composite elastomer are closely bonded with other parts in order to provide the function of moving, buffering, shock absorption and noise reduction.
Physical and mechanical properties of the two kinds of rubber experiment data table: Item Hardness (shaw) A Tensile strength MPa Elongation at failure % Permanent deformation % Tear strength N/mm Abrasion cm3/ 1.61Km Pattern ground rubber 79 24 450 10 59 0.24 Base Grounding glue 72 26 510 17 98 0.21 Note:Conditions of vulcanization:152℃×15min Conclusion 3.1 Adding N330 carbon black in the NR/SBR system improves the strength of the composite materials.

Data from the pots without plants indicated that there were also TP losses, but that significantly less than the magnitude observed in the waters with plants(P< 0.05).
In both treatments, the order of TP concentration was: Acorus calamus > Iris sanguinea,> Iris pseudacorus. 3.3 TP removal efficiency Contribution of Iris pseudacorus group in T1 and all three species in T2 to the reduction of TP increased as the time increased during the first 3weeks, while TP removal efficiency of Acorus calamus group was the highest at 28d and still increasing, and Iris sanguinea group was the highest at 14d in T1(Figure 2).

Because North China Electric Power Research Institute has used the same experimental method for calcutating the rupture life of P91 steel welds, whose test data were listed in table2-1.
Conclusions (1) At 566 ℃ the creep damage cracking test shows that the ability for anti-plastic fracture, cracking and crack propagation of resistance to damage of high pressure steam conduit pipe with low hardness is very poor.In order to ensure safty temperature and pressure reduction operation on the unit should be done

The fatigue test data of the HTGN specimens are also plotted in the figure.
The S-N curves in 3%NaCl solution are represented in Fig.5, together with the data in laboratory air.
In addition, fatigue failure occurred at applied stresses below the fatigue limits in laboratory air, indicating the reduction of fatigue strength in the corrosive environment.
