It is presumed that the semisolid metal with a low solid fraction increased the number of globular crystals.
The dendrites shown by arrows A separated from the solidification layer as the grain boundaries were re-melted by the latent heat released from the semisolid metal at the center.
The thickness of the zone of globular crystals indicated by arrow Z decreased and the number of the fine globular crystal decreased as the pouring temperature of the molten metal decreased.
If this is true, the quantity of globular crystals increases when a semisolid slurry or low-temperature molten metal is poured, as the quantity of re-melted globular crystals formed on the roll at the tip of the back dam plate decreases and the number of newly formed crystals increases.
The number of dividing dendrites in Fig. 3(b) is fewer than that in Fig. 3(a).

In 2008, the reduction of rice in the world's major grain-producing countries led to sharp drop in their exports of agricultural products, which resulted in skyrocketing food prices, violence and even bloodshed in some areas of food-importing countries.
The forecast model of agricultural and livestock products price In fact, a phenomenon is often associated with a number of factors, and it is more effective and realistic to predict or estimate a common dependent variable by a number of the optimal combination of independent variables rather than just one variable.
A number of these factors are used as explanatory variables, and forecasted prices will be interpreted as variables, price forecasts multivariate linear regression equation is constructed. 1121 ii YQQX QX = +++ A

Silicone PSAs, solid content: 60%; nano-SiO2, average grain diameter: 30nm; ano-Al2O3, average diameter: 30nm; siliane coupling agent, A151.
In this study, the tack of PSAs was tested using the method of oblique plane by rolling boll, and the number in TableⅠ means the size of boll, that is, the bigger size is, the better tack PSAs has.

In the range from T5 to T20, weight loss is mainly due to the fracture of side chains and the degradation of molecules chains, the number of crosslinks was increased with the growing of content of nano-SiO2, so the system of bonding force also increased, thus the thermostablility of nanocomposite enhanced, and then the T10 and T20 grow with the increasing of nano-SiO2.

Thus, the structure of the coating is homogeneous, which indicates the completeness of the processes of interaction between the grains of frit compounds № 11 and 12.

The relative wear resistance of steel determined by the formula: , where gt, gr – value of the mass loss of test samples and reference samples of test material, g; ρt, ρr - density of the reference and the test material, g/cm2, Nt, and Nr - the number of revolutions of the reference roller during testing and study materials.
After nitriding there are structural changes in the steel R6M5 surface, reduce the number of carbide particles. 25 µm b) a) 50 µm Fig. 2.
It is visible, that in the initial state in the structure of steel there are two carbide types: very bright colored carbides containing higher-atomic-number elements and grey carbide containing lower-atomic-number element.
Under a light layer is observed fine-grained transitional structure, which is a nitrogen martensite with carbide and diameter nitrided inclusions.

For example, a number of steel grades are required to have a phosphorus content below 0.015%.
For a number of alloys with molybdenum, it is possible to significantly accelerate the oxidation process due to the formation of a low-melting oxide MoO3.
At 1250oС the number of defects in the form of bubbles, cracks in the scale layer, partial delaminations from the surface of iron increases significantly, the oxidation rate of the metal also increases.
In this case, the oxide is wedged into the metal on the side of the outer layer and surrounds the grain with a continuous layer, and is also released in the form of small coalesced particles [11].
The number of liquid iron oxides formed during the melting of the mixture can be regulated by the surface area of the charged mixture and the chemical composition of the scrap. including by applying the powder components to the surface of the loaded scrap.
