Measurement conditions and data treatment To implement the proposed adjustment system (Fig. 1), which includes the controller unit (CU), the transmission provides a constant current through the electrochemical cell (EC), and a feedback loop in which the determined value of the current correction: , (1) where - system’s reaction coefficient (feedback depth), - the slope of potential values,, token at adjustment’s time window, Т:.
For each chronopotentiogram an amount of electricity, wasted to the inversion reduction reaction of gold: . (2) The adjustment factors and , determining the amount of adjustment, have been identified by means the of steep ascent optimization method.

Due to the very small amount of published data the author has failed to confirm this assertion.
Summary The results of the analysis allow to conclude, than relief holes, used in thin-walled girders, ribs, etc. constructions, cause an increase of the critical force and a significant reduction in weight, but also carry the risk of create significant stress concentration in the webs and a significant increase of the load in connections webs and skeleton.

Hardness data may be strongly influenced by external and internal factors: deposition parametres, microstructure and residual stresses (σr) presented in thin coatings.
On the other hand, carbon addition has beneficial effect on the reduction of the coefficient of friction [4, 5].

Assume the input torque is 1Nm, and the reduction factor of the speed reducer is 4, thus the output torque of the speed reducer is 4Nm.
The sea –trial of this system is scheduled in the near future. 7 Further work Data get from the laboratory is not yet complete.

At present, different methods are used to treat chromium-containing wastewater, mainly including biological method, ion exchange method, chemical reduction method, electrolytic method, chemical precipitation method, membrane separation method [1].
Data Processing The removal rate and the equilibrium adsorption amount of Cr (VI) are as follows: D=×100% (1) qe= (2) Where Co is the initial concentration of Cr (VI) before the adsorption, Ce is the concentration of Cr (VI) after the adsorption, V is the volume of water sample and m is the quality of the adsorbent.

Besides, LaB6 nanoparticles attracted much attention due to excellent optical properties including remarkable reduction in UV transmission and addition in near-infrared absorption [4, 5].
The film had preferred orientation of (100) plane in comparison with the standard data for LaB6 (card file JCPDS 34-0427), as the nucleation migration rate of the film was relatively low due to the low temperature, it was against the growth of the crystal plane with high index.

Generally, the following forces actuate upon the tractor-trailer system, which leads to speed reduction: braking force, rolling resistance force, aerodynamic drag, frictions in the bearings of the rolling system etc.
For the mathematical model we considered the following input data [6]: mT = 3395 kg (unballasted tractor); m1 = 1376 kg – weight distributed on the front axle; m2 = 2019 kg – weight distributed on the rear axle; L = 2530 mm – wheel base; h = 847 mm - height of center of gravity of the tractor; v0 = = 42 km/h – initial braking speed; f = 0.03 – coefficient of rolling resistance; φ = 0.4, 0.5, 0.6, 0.7, 0.8 – coefficient of road adhesion.

Analyzing the data, it is possible to verify the predominance of Al2O3, SiO2, quartz, and Fe2O3 content in the composition of the clay.
Furthermore, this affects the reduction of the pieces dimensions.
