And the intermediate phases dwindle in numbers.
And C2S minerals have regular form of round grain and clear boundary, about 20-30 μm.

In the last couple of decades, the issue of multi-physical coupled simulation technology for cast through process simulation has been a focus of many scientific research works, where a number of advanced simulation methods have been developed.
The sand casting molds were produced by 3D printing of 170µm grained silica sand bonded with furanic resin at a layer thickness of 280µm.

Finally the ingot was grained into the powders for X-ray diffraction measurement.
The contents of multiphase can be determined by the following formula according to the structural refinement parameters [15]: = (3) Where wi is the weight percentage of the ith phase, Zi, Mi, Vi and si represent the number of formula units per unit cell, molecular weight, cell volume, and scale factor in the ith phase.

The XRD pattern of pure Ni(OH)2 is shown in Fig. 1(c), combined with transmission electron microscopy analysis (not shown here), the structure of the as-deposited pure Ni(OH)2 exhibits poor crystallinity with very small grain size.
In the Ni 2p region (Fig. 3(b)), both for pure Ni(OH)2 and the composite, the spectrum shows a number of extra lines marked as satellites, Ni 2p3/2(s) at 860.9 eV and Ni 2p1/2(s) at 879.1 eV, in addition to the expected Ni 2p3/2 and Ni 2p1/2 signals (Ni 2p3/2: 855.9 eV, Ni 2p1/2: 880.3 eV).

The red loam was the main land to plant grain and fruit.
Rainfall uniformity formula is as follows: (1) In this formula: K-uniformity coefficient; xi-measuring points rainfall,mm; -average rainfall of point,mm; n-number of points[11]; The rainfall intensity runoff plots was heavy rain level.

It is the national dominant grain-producing area and the main ecological animal husbandry base in Shanxi Province.
In order to solve the problems of large number of per capita quantity of rural residential area, the scattered layout, lack of sound planning of village construction planning and shortage in public service facilities, the consolidation modes such as Abolishment and combination mode, Local transformation mode, Town import mode and Transference for ecological construction mode can be applied to rural residential area to promote intensive and economical utilization of land, realize the coordinated development between urban and rural and accomplish the construction of new rural area.

In their work, they have combined this law with another law to determine with a numerical model the final grain size in chip area.
σy= σs+ σ0-σs+Aεpnexp-rεp with σi=Ki.Zmi (2) Two sets of parameters reported in table 3 have to be determined for this law with reference to the variable Z which is the number of Zenner-Hollomon.

Raise in heating temperature (austenitizing) mainly affects properties of quenched and tempered deposited chromium-tungsten, which are associated with increase in carbides dissolution and growth of austenite grains.
According to [3], only a small number of positions in the cell are replaced by vanadium atoms, and iron and chromium replace tungsten in large quantities.

In zones, where the activity of the aquatic medium was minimal, fine-grained pelito-aleuritic sediments were deposited, characterized by lower reservoir properties; - conditionally, the whole area under study can be divided into five paleofacial zones generalized by geophysical features.
A detailed analysis of the experimental sites production well stock work showed that in a number of cases the technological effect was calculated without considering other interventions (formation hydraulic fracturing (FHF), "Galka" reagent injection into adjacent injection wells, unscheduled measures) or in conditions of unstable operation of production wells.
