Build in numerical integration is used to determine the maximum values of the magnetic flux density according to the equation:
Bm= 1z2SFeu2dt (5)
us – the instantaneous value of the secondary voltage, z2 – are numbers of turns of the secondary windings, SFe - the surface area of the cross section of the magnetic core, lFe - the average magnetic flux path in the core.
The maximum value of the magnetic field strength is determined form equation: Hm= i1z1lFe (6) i1 - the instantaneous value of the primary current, z1 – numbers of turns of the primary winding.

A number of industries are focusing on the development of this special Mg alloys including i. aerospace application in order to minimize emission reduction and fuel efficiency, ii. medical application due to its high biocompatibility and self-degradable in human body and iii. electronic application since it exhibits great improvement in strength, heat transfer, and ability to shield electromagnetic interference and radio frequency interference as compared with current plastic counterparts [2].
This indicated that the formation of fine crystallite which is due to the increasing number of collisions per unit time during milling process.
The reduction of pore size and its distribution at higher speed increased the contact area between grains leading to enhance densification effect, sinterability and its properties afterward.

The grain size distribution curve indicated that sediment is predominantly silt-sized with 60% of clay; the percentage of particles whose diameter is less than 80µm is about 78%, and tuff particle size lays mainly around 500 um, with neither fraction of particles below 5 um or above
1.25 mm.
The ceramic waste powder shows a completely different size distribution, with a large number of coarse particles (about 92% above 1 mm) and nearly 34% ultrafine (size <125 um).

For the high mountains and steep on yunnan laterite area, there are a lot of lateritic slope, a long period in climate condition of warm, wet, more rainy and partial acid, In combined effects of underground water and infiltration of rainwater especially acid rain, will produce hydrolysis reactions and corrosion function to laterite particles and the connection among grains, leading to the composition of laterite happen migration with seepage flow, lead to the changes of macro and micro characteristics of slope laterite, lead to serious geological disasters.
(a) The effect of compaction energy or moisture content or temperature (b) The effect of immersion time Fig.2 The migration ability of iron ion in laterite in different effect factors The migration process of iron ion in laterite in water environment The migration process of iron ion in laterite is actually the process that adsorption iron ions in laterite grains surface dissolve and migrate into water solution in water environment.
With the extension of immersion time, the number of the iron ion migration out of the laterite is more and more large.
In the water environment especially seepage, the migration of iron ions directly affect to the linking performance between laterite grains, thereby affect to the structural stability of the laterite and even the occurrence and development of lateritic geological disasters.

., grain size can be reduced) [12], (2) Effective solidification allows for more precipitation hardening [13]; and (3) Balance Precipitation (i.e., phases detrimental to mechanics or corrosion properties) can be suppressed by rapid cooling [14].
Because traditional casting features grain separation at the contour, it requires further machining, which raises production costs [17].
PM avoids problems associated with the traditional smelting process, in addition to controlling the growth of the grain [21].
The trend analysis showed that there has been a growth in the number of publications, especially reflected in the last year; however, these publications were distributed in a wide range of journals.

The effect of the number of cycles of SILAR on the morphology and size of the quantum dots has been investigated.
The effect of SILAR cycles number on the QDs size and band gap was studied.
Repeating the number of cycles enables the particles grow in a controlled manner.
The images revealed that the surface consisted of spherical grains and it had a smooth appearance.
The intensity of the peak increased with the number of cycles increasing.
