The experimental results show that the diameter of primary Si particle in the semi-solid slurry is gradually increased with the increase of holding time,in which the growth velocity of the primary Si particle is very slow before 15 min while is rapidly increased after 15 min.
Observation by analytical electron microscopy showed that the (Ti_xV_(1-x))(C_yN_(1-y)) particles may be act as a role to slow the growth of grain boundary nucleated ferrite side plate (FSP) or not depending on the growth direction of the FSP.
The summarized results demonstrate that the dependence of pitting current on time comply with four functions of time, that are t1/2, t, t2 and t*ln(t), and each of them corresponds to a specific pattern of pitting growth.
The results show that with optimum addition of rare earth element yttrium in the alloy ZA-27 the fine YAl_3 phase forms. The fine YAl_3 granules can act as the condensation nuclei of α phase and the number of the α phase′s nuclei increases greatly and the growth of the nuclei comes in for restrict during the crystallization and the alloy's grains become fine and the segregation reduces.
The precursor matter can be obtained by the co-precipitation method in the prepared Ni-Zn-ferrite process, the properties such as particle size distribution, specific surface area, crystal growth and particle shape have changed before and after the hydrothermal process treated.
Complexity of Homogeneous Spaces and Growth of Multiplicities
We give a representation-theoretic interpretation of this number as the exponent of growth for multiplicities of simple G-modules in the spaces of sections of homogeneous line bundles on G/H.
A necessary and sufficient geometric condition on the growth of the boundary of approximate tiles is reduced to a problem in Fourier analysis that is shown to have an elegant simple solution in dimension one.
We prove a Tauberian theorem of the form $\phi * g (x)\sim p(x)w(x)$ as $x \to \infty,$ where p(x) is a bounded periodic function and w(x) is a weighted function of power growth.
A complex Radon measure μ on ?n is said to be of at most exponential-quadratic growth if there exist positive constants C and α such that.
