Introduction Recently there have rather actively been studied metastable condensed systems possessing a number of new physical-and-mechanical properties differing from the properties of equilibrium systems.
A special place among them is taken by nanostructured materials whose volume significant part make grains boundaries.

GCMS structure: Samples through interfaces (the interface is the key to the GC system, interface effect: 1 Pressure matching--mass spectrometer ion source vacuum whose pressure matching in 10-3 pa, and GC chromatography column whose outlet pressure as high as 105 pa, the role of the interface is to make both pressure match. 2 Component concentration-- There is a large number of carrier gas in the flow of gas from GC chromatography column, the role of the interface is used to discharge carrier gas, makes analyte concentrated then enter into ion source).

It’s generally believed that WPC tool wear is mainly due to mechanical abrasive grain wear and chemical wear.
For high speed milling which produces a large number of chips, high coefficient of friction between the chip and tool and structure of cutting tool may lead to obstructed chip.

. % Ni alloy, which has the Unified Numbering System (UNS) of C70600.
The microstructures of copper-nickel alloys with different alloying elements show a single phase for each alloy with small grains with an average diameter of 70 µm.

Higher shear stress value is needed to initiate shearing with the increase in slurry concentration due to the presence of relatively more numbers of solid particles.
Yang, Experimental study on correlativity between rheological parameters and grain grading of coal gauge backfill slurry, J.

Researches on material properties were mainly focused on impurity elements (such as P, S, Mn elements), yield strength and grain boundary carbide [1].
At the same time, a large number of intergranular fracture morphology (Fig. 6) was found, indicating that the rotor material was brittle.

Using a condition of balance of chemical potentials between a crystal grain of radius r, representing firm solution A in B, surrounded by its own melt in view of surface pressure [15], the equality of chemical potentials looks like: , (1) Using (1) for temperature of CM for nanoparticles it is possible to receive: , (2) And for nanofilms: , (3) Where - chemical potential; σ - interphase energy; Ω - atomic volume, λ - heat of CM.
It is necessary to note, that in a number of works [16-21] influence of pressure on phase transitions in nano-objects immersed in the matrix of the second phase was studied.

The mixture of α and b β phases was arranged like a weave pattern (Widmanstatten structure) on the primary β grain boundaries.
In the Ti-6Al-7Nb alloy, the number of the α phase decreased after solution treatment, and therefore the hardness value decreased.

The sand grain roughness height for the iced surface was calculated with an empirical NASA correlation described by Shin et al. [8, 9].
(2) where, is the water volume fraction, is the droplet velocity, is the droplet drag coefficient and Fr is the Froude number.

The products stored at 37˚C, the total number of colonies were determined, and the results showed that the products reached the standard.
