in the corrosion resistance was revealed. The polarization resistance of the pure sol-gel coating was mildly increased by extending the immersion time from 15 to 30 min more probably due to the filling... by extending the immersion time due to gradual penetration of the corrosive solution through the micro and nano-metric defects. However, the polarization resistance of the sol-gel nanocomposite containing......
unrestricted root intermingling is permitted between ZhongyouzaⅠand pai-tsai. By taking 10 mg/kg Cd treatment into consideration, the shoots of pai-tsai attain the same biomass irrespective of the extending..., irrespective of the extending of root intermingling permitted (Fig.4(a), black bars). Similarly, shoot biomass of ZhongyouzaⅠ also remains unaffected when the roots intermingling of the two species......
in the zones around the rounded edge (see Fig.2) of punches (Fig.9(a)), and then the deformation zones extend (Fig.9(b)). The extending speed along loading direction of male die is quicker. Finally... until forging is close to ending (see Fig.10(c)) for the reason of the low extending speed of plastic deformation zone. 6 Conclusions 1) The simulations show that both loading paths allow for forming......
in the practicable rock mass. The deformation and fracture mechanisms of the rock mass are closely related with the cracks generating, extending and coalescing. So, more and more people think much of the long-term stability of rock engineering. And the extending mechanisms correlating with the environment of cracks are becoming a studied focus. According to the principle of fracture mechanics, before the stress......
recrystallization (DRX) in many metal targets (copper[6], iron[7], stainless steel[8]). A slightly softer zone of microhardness profiles extending from the crater bottom was observed as a consequence... diffraction rings in the SAED pattern in Fig.5 indicate that randomly oriented grains were obtained. Figure 6 illustrates residual microhardness profiles extending along the impact axes from the crater......
resistance Rp depend strongly on the immersion time. The polarization resistance Rp increases with extending immersion time from 1.7 h to 8.7 h. Correspondingly, the corrosion current density Jcorr... that the polarization resistance Rp increases with extending immersion time from 1.7 h to 8.7 h (Table 1). Then, during the immersion period from 7 h to about 60 h, Rt remains at a high stable value......
bound theorem, the factor of safety for slope is exactly 1.0. Extending this theory to tunnel stability analysis, we can conclude that when the actual supporting pressure is equal to the critical... water pressure is completely produced by the part of pressure acting on the failure boundary. As the pore water pressure has no effect on the failure mechanism of shallow tunnel, by extending......

The individual nanostructure usually exhibits a hierarchical structure with various sized... have been discussed in the above section. Further extending the reaction time up to 20 h (Fig. 3(d)), the flowerlike architecture gradually transforms into thick nanosheets and fragments. On the basis......
ductility of alloy is significant in exploring the potential of Al-Li alloys and extending their application in aerospace industry. Nowadays, the artificial neural network (ANN) is one of the most powerful.... Further, traditional T8 temper combining with pre-aging and mid-deformation may become an effective process in extending the potential of Al-Li alloy.
