This paper focus on the velocity with the number of 5m/s, 10m/s, 15m/s, 20m/s and 25m/s, and also considers different diameter of particles, shown in Tab. 1.
This thesis deals with the separation efficiency under different particles concentration with the number of 1%, 3%, 5% and 7% under the same flow rate.
Tab. 4 shows the simulation calculation number of total efficiency and separation efficiency under different particle concentrations, which has been drawn into Fig. 5 for visual understanding.
High separation efficiency can be obtained through the increase of processing volume, but the energy consumption is too large and some negative effects can be formed accompanied with grain crushing or wall abrasion when the volume reaches a certain extent.

Additionally, the ionic radius of lanthanides decreases with the increase of their atomic number [11].
The values of Z = +3 and coordination number CN = 6 are typical for most of the studied elements.
Subsequently, the variations of Tg found in the current study may be related to changes of the glass structure at elevated temperatures rather than to a change in coordination number.
Satet: Influence of Grain Boundary Properties on Microstructure Development and Mechanical Behavior of Silicon Nitride Ceramics (PhD Thesis, IKM 038, University of Karlsruhe (TH), Karlsruhe, Germany, 2003)

The deformation twins generate in the process of austenitic stainless steel tensiles at room temperature, their numbers increase with the increasing of the strain [5, 6].
In Fig.6 (b), (c) there are the α- martensite induced by strain indicated by the arrow, and the sheet organizations grow along the grain boundary to intracrystalline, formed in the twins crystal[4].
As shown in Fig.5 (b), part of the grid ε-martensites exist and a large number of α-lath martensite can be found, which is the intermediate phase form γ austenite deformation to the α-martensite.
The ε-martensite was the middle phase of γ → α-martensite transformation, and in the same method of cold working, the greater the cold deformation is, the larger the number of deformation twins and the martensite phase are.

However, the in situ reinforcement particles are coarse in size and sharp in circumference, meanwhile exist a large number of needle-like silicon phases.
A number of technological approaches have been proposed to address these problems[10-12].
When the melt is solidified, the α-Al come from eutectic α-Al+Al3Y become crystallization nuclei, which play the role of grain refinements[13].
Secondly, yttrium can form rare earth oxide solid particle with oxides in the melt, as the heterogeneous nucleation base of α-Al, part of them can promote a large number of α-Al nucleation, thus the alloy matrix is refined.

During choosing the initial clustering number, the paper references the characteristics of users, first select an appropriate number of clustering and analysis through clustering results, then adjusting the cluster number, seeking to achieve optimal clustering effect.
Where represents the satisfaction degree of interaction, represents the number of interaction.
(2) The number of interaction.
We use the interval number of interaction as the attenuation factor.
A fine grain trust model based on domain and Bayesian network for P2P E-commerce system [J].

Because of these advantages, it has been used in a number of fields, e.g., dynamic fracturing, wave propagation, and nuclear waste disposition.
The GPU computing is called as fine-grained parallelization.

Its rationalization that the bomb puts out a fire through window reliably was confirmed by using ANSYS/ LS-DANY to simulate the dynamic process that the extinguishing bomb penetrates window, which provides a reference for extinguishing bomb to conduct flight test, cut down test number and lower experimental cost.
Liqiang Du[4], etc studied the ultrafine dry powder fire extinguishing technology; Bin Zheng[5], etc studied the release and diffusion ability of ultrafine grain fire extinguishing agent.

Making China the number of cement concrete road construction in recent years, increasing year by year.
Coarse aggregate concrete surface must be graded with the system expected, the maximum diameter divided by 2 to 4 for grain size of aggregate blending.

In addition, the indexing of the nodes and elements is closed, which means there are no gaps in the numbering of the index, starting by zero.
This context involves not only multiple scales, but also different temporal and spatial resolutions as well as different data fields (e.g. temperatures at macro level, grain identifiers at micro level).
Thereby, multiple datasets are representing material and work piece states at different spatial scales, e.g. grain level (magnitude of µm) and work piece scale (magnitude of m), spatial locations, temporal scales (ranging from seconds to hours for sub-processes) and temporal locations.

Hemicellulose and lignin removal from brewer’s spent grain or steam pretreated corn stover make cellulose fibers more susceptible to the enzymatic attack, thus increased the glucose yield [6, 7], and it was also reported that biomass subjected to dilute-acid pretreatment to remove hemicellulose made it more susceptible to enzymatic attack [8, 9].
Viable yeast number was determined by plate counting method.
