The joint deformation of the robot is mainly from the transmission, the reduction gear device and the servo driving system.
Firstly select the 40 sets of data as the initial population, the position of the 40 point data in the robot coordinate system is shown in Table 2, the individual genetic evaluation function (11) is used to solve the optimal position of the workpiece coordinate the iteration after 1000 times, the position of the point in the coordinate system of the robot is nij = [-804.282 -932.68 848.4414] , when the workpiece coordinate is in this point ,the deformation of the robot end-tool is minimum during the milling process , the machining errors is guaranteed within 1.04mm.As shown in Figure 3, the vertical axis shows the maximum of the deformation error of the the robot end-tool for each workpiece coordinate point corresponding the 100 feeding trajectory points , compared the maximum of the tool trajectory error shown in Figure 4 with each set of data in Figure 3, it shows that the deformation of the end-tool of the resulting workpiece position is the after the hybrid genetic algorithm optimization

X-ray diffraction (XRD) was used to test the crystallization properties of films, and relative calculation was conducted based on the diffraction peak width data in the XRD spectra to obtain the relationship between the grain size and laser fluence.
Full width at half maximum data of each diffraction peak is obtained by fitting of Mo (110) orientation diffraction peak under each laser fluence (XPS peak).
As shown in Figure 2, a fitted curve is obtained with data fitted by Equation (5).
Soft x-ray reduction lithography using multilayer mirrors [J].

If we could combine the biogas with sewage, it would play a significant role in the work of energy saving and emission reduction.
In this context, we can show locations, factors and sizes of exergy losses clearly with the exergy analysis of system or process, finding out what is the real energy loss, looking for the methods of energy conservation, so that we will get reliable data in improving system efficiency [9-12].
Based on the above data, the pressure-enthalpy diagram is given by fig. 2.
The data are as table II.

The data show that the arcing process is associated with the generation of a grey colour, which probably results from partial reduction due to localised melting [17,18].
These data show the following trends (Table 2): Table 2.
From these data, the following observations can be made with regard to the effect of the different parameters, as summarised below: 1.

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.

To achieve this goal, industrial waste can be used in the production of cement, which leads to a reduction of CO2 emissions and the use of natural resources.
However, data in the scientific literature on the effect of additives on the crystallization of these compounds and their properties are incomplete and often contradictory.
The CuKα radiation (U=40 kV and I=40 mA), 0.02 mm Ni filter, a Bragg–Brentano geometry, and a fast counting detector Bruker LynxEye were used for collect data.
The duration of hydrothermal treatment was 16 h (a and c) and 72 h (b and d) The XRD results were confirmed by STA analysis data.

Introduction The methanogenic bacteria are a diverse group of anaerobic archaebacteria, and metabolically are divided into those that specialize in CO2 reduction and those that also use acetate and/or methyl compounds [1, 2].
., Cary, NC, USA) was used for the experimental design and regression analysis of the data obtained.
The experimental data represented the means calculated from three independent samples Figure 2.
The experimental data represented the means (with standard deviation) calculated from five independent samples TABLE II.

However, the knowledge of how the magnetic field affects the kinetics of atomic diffusion in ferromagnetic materials is still lacking, and the corresponding experimental data are scarce.
The forged and hot rolled Fe sheet was further processed by two-step cold rolling with the total reduction of 85%, followed by recrystallization annealing at 850 °C for 80 s.
Interpolation (for the field of 5 kOe) and extrapolation (for zero field) of his data for the temperature of 747 °C gives M=5.58·10 -2 T and M=6.15·10 -2 T for the zero and 5 kOe magnetic fields, respectively.
However, the data on temperature dependence of surface [4] and dislocation pipe [6] self-diffusion indicate that magnetic effect in short-circuit selfdiffusion is much stronger than in the bulk one.

The data are summarized in Table 1.
Thermal data for the dehydration and decomposition of the complex contain latticed water.
Combine the IR, electronic absorption, and elemental analysis data the imaginable structure of the complex was given in the Scheme 1.
Increasing rutin-Mn concentration caused a reduction in the fluorescence of serum albumins, It is interpreted that the complex-system formed between serum albumins and rutin-Mn [7].

However, additional interpretation of these data is needed.
The sample had previously been compressed to a height reductions 13 %, 32% and 50%, and fore MPF had been measured after every deformation step.
