The diameter of latex grain is an important index of good or bad performance of the emulsion[1-3].
Emulsifier concentration [s] and the number of micelles [Nm] has the following relationship: [ Nm ] ∝ [ s ]0.6 To obtain more latex number, small particles diameter, the amount of emulsifier is the more the better.
Both of them would cause the number of latex particles increased, the diameter decreased.
The initiator concentration was too low, resulting in too small number of free radicals and latex particle increasing.
This is because when other conditions were certain, the number of the latex particles was certain.

The simulation results show that the abrasive grains near the addendum, tooth surface and tooth root can be subjected to corresponding shear stress.
Introduction In order to meet the needs of high-speed, heavy duty, low noise and high life expectancy of modern mechanical transmission, a growing number of helical gear transmissions using hardened precision gear, perfection and application of hard-toothed surface finishing are the main development direction of modern gear manufacturing technology.
Helical gear is an involute-column-bevel gear, number of teeth Z=26,helix angle β=15°, normal plane modulus mn=1.25mm, normal plane pressure angle αn=20°, normal plane addendum coefficienth , normal plane headspace coefficient , tooth width B=48mm.
The experimental results display that the surface roughness Ra decreases when the number of machining cycles increases, and Ra value downward trend has slowed with the increase in the number of machining cycles.
Effects of number of working cycles on surface roughness at three positions.

With the increase of Nd, the number of spherical I-phases is reduced and rod-like phases increased.
There are a large number of rod-like phases in the matrix and spherical I-phase is correspondingly reduced.
At the same time, there is different distribution of the enrichment of Nd atoms on every crystal plane of formed tiny quasicrystal grains.
Adding 5% Nd, there is the largest number of spherical I-phases distributed evenly in the matrix.
With the increase of Nd, the number of spherical I-phases is reduced and rod-like phases increased

., a reference which would make connotations with others specifications: the materials, grain, strength, structure, binder [10].
The reference could be 30A60N5V_XXXX, were 30A represents the abrasive material, 60 – grain (medium), N – strength (medium), 5 – structure (medium), V – binder (ceramic), XXXX – dimensions.
On one sheet is described the product by a reference (Product reference), the components number (no_block) and the actions number (no_dyn) associated with the product (Table 4).
For each entity they are introduced different atributes such as the block’s name (name), the path where the macro find the block (path), point of insertion (x,y,z), block angle (angle), the entity layer (layer), the start/end point for a line/polyline/rectangle (point), the coordinates for a piece from a block (ech_x,ech_y), or the color number from AutoCAD files as presented in Table 5.
There were taken into considerations two of the parameters: rotation (r#1) with the rotation point (pt_rotation) radius (radius_parameter), angle (angle_parameter), the action locations (label location) and linear (L) with the start/end point, label location, numbers of grips (grips) and the corresponding block (block_dyn) (Table 10).

To obtain the Ca-TZP
materials with excellent mechanical properties related to the transformation toughening mechanism,
the extremely fine microstructure with tetragonal grains of ~0.1 μm in size is required.
Additionally, both the monoclinic phase content and number of the needle-shaped crystallites (Fig. 6) increased with the solution pH.
Number content of the needleshaped crystallites is also included.
This is consistent with the general knowledge on densification during compaction of the polymodal systems with controlled grain size distribution.
However, in this case it was connected with the increased number of the monoclinic needle-shaped crystallites and therefore increased monoclinic phase content in the calcia-zirconia nanopowder.

SPD processes use extensive hydrostatic pressure to impose very high strain on bulk solids, producing exceptional grain refinement without introducing any significant change in the overall dimensions of the sample [1].
In particular, biocompatible unalloyed titanium with improved mechanical properties can be used in a number of products instead of Ti-AI-V and Ti-Al alloys.
The number of TE passes can vary from 2 to 7 depending on the material, deformation conditions and requirements to the properties of the final product.
At the same time, with increasing the number of TE passes, the contribution of the mixing effect rises too.

As a complex physical process, grinding process is subject to a number of input factors and produces
a variety of physical and mechanical phenomena.
Suto and Sata [2, 3] by measuring the number of effective abrasive and wear area to get the grinding wheel topography.
Hegeman [6] found the shape of abrasive grains was more closely resemble the shape of ellipsoid rather than spherical by SEM photographs.
The results show that the algorithm using coupled FEM and SPH can simulate the deformation of any material cutting layer, while avoiding a large number of SPH particle calculation of time-consuming.
