After 1~2 minutes until the constant-current potentiostat displays stable data, the displayed data will be recorded.
During the test, the average data of four specimens in one same group shall be taken as the test result.
These curves indicate that the corrosion potentials in galvanized bar specimen are very small, and the reduction of corrosion potentials is caused by the low corrosion potential of zinc.

Investigation content and method According to the 《Technical code of maintenance for urban road》(CJJ 36-2006) about the provisions that maintenance condition assessment[4], investigating the road conditions on site, mainly adopt the artificial data acquisition and photograph manners to record.
Compared with the previous pavement damage condition standard maps research results, we conduct the data acquisition and analysis.
The existence of these road diseases result in the reduction of roads’ traffic capacity, poor traffic organization, low comprehensive service capacity of road, seriously affect the smoothness and driving comfort of the road, some even have serious impact on traffic safety.
Conclusions In this investigation, the asphalt pavement roads mainly located in the core area in Hohhot, based on the relevant provisions of 《Technical code of maintenance for urban road》(CJJ 36-2006) and the previous pavement damage condition standard maps research results, conducting the data acquisition and analysis.

Fig. 2 – Denavit - Hartenberg system for axis coordination Robots 4R (serial) Both the kinematic chain modules and the mechanical hand are driven by DC motors by worm gear-wheel reduction.
The system is runs a MATLAB program on a PC which takes data from the serial port, through the data acquisition system, the current as read on the standard resistance of the motors force circuits.
Fig.6 Diagnosis of the of Kinematic Parameters Fig.7 Diagnosis of the of Dynamic Parameters Data acquisition is recorded and synchronized on RASTER, “.pcx” and “.bmp” files, as a function of various factors in connection with positioning and orientation accuracy.

Fatigue data, in the form of stress vs. cycles to failure (or) strain vs. cycles to failure (or) fatigue crack growth rate data is used to predict the residual life.
Often the quantity of material available for generating fatigue data is limited, especially, if the material is scooped out of existing component of a power plant.
This has prompted us to develop test procedures to determine the fatigue data of materials from a limited volume of material.
This poses restrictions on fatigue data generation for in-service components.
The force and displacement data was acquired at a data sampling frequency of 20 Hz and it was continuously monitored.

The database consisted of rupture life data in the range of 1,000 to 10,000h.
The predicted data compared well with the existing RCC-MR data upto 35 years.
Its efficacy vis-à-vis other methods for treating stress rupture data for multiple heats was also established.
Fig. 5 Multiple heat stress rupture correlations using heat indexing constants, P1 and P2, based on 590 data sets.
The results have shown that creep and fatigue design of components operating in sodium environment based on data from tests conducted in air, is conservative.

The experimental data was analysed by both Freundlich and Langmuir isotherm models.
Various methods have been studied for the removal of cadmium including electroplating, evaporating, oxidation, reduction, membrane separation, ion exchange and adsorption [5-6].
Kinetics studies and Adsorption Isotherms Model In this study, the kinetic data of Cd(II) on the adsorbent studied was analyzed in terms of pseudo-second-order reactions.
For the adsorption isotherm model, the equilibrium data obtained for Cd(II) removal using SPW, SB and AC was tested with one isotherm models which is Langmuir isotherm.
Adsorption Isotherm and Kinetic studies From Fig. 3(a) and Table 2, it was found that the data obtained is linear with good correlation coefficients where the correlation coefficients (R2) were more than 0.999 for the three types of adsorbents.

The data indicate that seeded mortars can improve performance in several areas, notably carbonation rate (25%-45%), flexural strength (16%-60%), compressive strength (20%-55%), and sorptivity (18%-25%).
However, the rapid hydration in the first stage causes a more non-uniform distribution of the hydration products, resulting in non-homogeneity in the microstructure and a considerable reduction in long-term strength development.
This initial hydrolysis slows rapidly once it begins, resulting in a reduction in heat evolution.
The data shows that MOS mortars carbonated quicker than the MC, by approximately 25%-45%.

However, comprehensive data on Namibia's wood waste generation, utilization, and disposal of unutilized waste are unavailable.
This lack of data hinders the development of effective and sustainable management strategies tailored to the country's unique needs.
This data is crucial for developing targeted management strategies.
It also provided data for estimating the percentage of the wood waste generated and for evaluating the quantity that remains unused.
Various statistical methods and tools were used to analyze the data.

The paper presents data about distribution of contact stresses on a rake surface and flank-land of a cutter in free orthogonal turning of a disk made from a titanium alloy (Ti-6Al-2Mo-2Cr).
Our experimental data allows calculating the components of cutting force and contact stresses on the rake and flank surfaces of cutting tools during titanium alloy (Ti-6Al-2Mo-2Cr) machining.
In our opinion it is connected with increase of temperature in the process of plastic deformation on an initial section of a flank surface chamfer and reduction of strength of workpiece material in the contact with a chamfer.
Our experimental data can be used to calculate the components of cutting force and contact stresses on a rake and a flank surfaces of cutting tools during machining of titanium alloy (Ti-6Al-2Mo-2Cr). 2.
