However, fluidized-bed drying of RDX is liable to generate a large number of RDX dust, posing some difficulty in subsequent dust recovery, dust handling and air exhaustion.
MRpre,i is the ith predicted moisture ratio, N is the number of observations, n the number of constants in the regression model.
The solution of Fickian equation in such conditions for different geometries has been presented by Crank [26] in Eq. (9): (9) where,is the half thickness of t the thickness of the RDX layer for drying from one side, and n = 1, 2, 3 . . . the number of terms taken into consideration.
Stochastic modelling of grain drying: Part 2.
Grain drying theory I.

Measurement of a number of relevant diffusion coefficients in minerals in recent years is improving the quantification of this aspect (e.g. [13-19]).
The as deposited amorphous thin films can be crystallized to produce interesting geometries on the nanoscale and several aspects of diffusion behaviour (e.g. grain boundary diffusion, surface diffusion, diffusion across heterogeneous couples) can be studied using these thin film coated crystals.
To simplify numerical modeling of mass transfer under these conditions, a number of concepts have been borrowed and modified from the materials sciences.
In the second study, we extend this to a system consisting of any number of phases and components and handle the problem numerically.
Areas where Research in other areas may benefit Geosciences: There are a number of areas where the Earth and Planetary Sciences stand to benefit by importing expertise from other areas.

As a result of testing the large number of organic liquids, it was established that benzyl alcohol is the most suitable medium for the reduction of nickel compounds.
Mean size of grains in the aggregates, determined on the basis of broadening of X-ray lines, is approximately the same in all the cases: about 100 nm.

There are number of film deposition techniques known, but few of the most utilized ones are briefly discussed above for the sake of completeness, as it is the aim of the present paper.
Typically synthesized polycrystalline films exhibit a high recombination rate due to existence of excessive grain boundaries and oxygen vacancies.
The properties are greatly affected by the grain size and their distribution, chemical composition of constituent phases.
Such grain boundaries, hetero-phases, inter-phases or inter-surface state interactions greatly affect their performance [1].
Impurity doping is largely intended to improve electrical conduction, by raising the number of charge carriers and/or by increasing the carrier mobility.

This required generating a large number of specimens by systematically varying the gauge length, gauge width, grip length and width of a standard geometry.
Fig. 1 Overall test specimen geometry with a list of all the different geometrical parameters All specimens were machined from an AZ31B-H24 magnesium sheet; a material known for its relatively small grain size and hence good superplastic behaviour in the as-received condition.
Also, let us not forget that these numbers are based on a moderate plastic strain of 1.25; deforming other superplastic materials to larger strain limits would certainly inflate these numbers.

In order to improve the wetting property of the melted powder, the plate surface was sandblasted with #35 of average grain size[5].
The thickness of the beam model which was varied by the number of forming layers was ranged 1 - 30 mm.
Fig. 6 showed the influences of the layered number on the base plate deformation and the residual stress at the consolidated surface under the base plate height of ts=20 mm.
The deformation height and residual stress increased with the increase of the layered number, and then became almost constant when the layered number was over 400 layers.
The increase of the residual stress was due to the increase of the consolidated layer, which was equal to the laser irradiation number.

Using astronautical mutation breeding technique, a lot of new high-produced and well qualitative grain crops, cash crop flowers and antibiotics have been bred home and abroad.

But a large number of overflow bubbles influence the safety of equipments and cause the adverse effects of the site conditions.
Especially for long duration, the crystallization of gypsum particles is long, and the size of grains is big.

After optimization of heat treatment process for the production, uniform microstructure, austenite grain size is very small (see figure 4 ,  5 ,  7 ,  8 ), Not only ensured the General mechanical performance of drill pipe, improved product toughness reserves, increases security.

In fact, the mother of the glaze and crystallization associated peripheral crystal grain occasionally uneven nanoscale phase separation structure of diffraction and opalescence behavior is affected glazed coloring, emulsion and gloss level of an important structural factor.
The enamel matrix is larger uniform micron-scale crystals, bubbles, white glaze group size larger than the wavelength of the incident light is produced by reflection and refraction of the whole band, the number, the more opaque glaze degree is also higher, so that glaze showing a strong jade texture.
