A measurement system for analysis of chemical and biological materials invasively has been developed by Fourier-transform infrared spectroscopy with attenuated total reflection (FTIR-ATR) techniques [7].
Experiment and Methods Experimental Materials, Instrument The experimental setup included an FTIR spectrometer(Vertex 70,Bruker Analytic GmbH Hamburg, Germany )with an attenuated total reflection (ATR) ZnSe prism(diameter=5mm) which represents the internal reflectance element(IRE).As shown in Figure 1,The incident light undergoes three total reflections of 45º at the prism/human skin interface, Each ATR spectrum in vivo of middle finger was the average of 32 scans in the spectral regions of 800 cm−1 - 1200 cm−1, the room temperature range oscillated between 25-27℃ ; resolution was set at 4cm-1.
about tissue fluid reached the surface of skin with time, finally the materials between the stratum corneum and the prism reached equilibrium and there was no additional materials could reach form the stratum corneum to the surface of skin, so the last six spectra remained stable as Figure 2 shows and the last six ratio values were nearly equal as Figure 3 shows.
The result shows there are some materials about tissue fluid reached the surface of skin with time.

Recently, by composing these two materials using ball milling, an increase of hydrogen storage properties has been observed [2,3].
Assessment of structural information contained in the powder XRD patterns was made using MAUD (Material Analysis Using Diffraction), a general diffraction/reflectivity analysis program mainly based on the Rietveld method and oriented to materials science studies [17].
However, these mixed or composing materials show incomplete desorption with only a partial formation of MgB2 and high content of side products NaBO2 and MgO.

Data on the state of production orders, machines, materials and human resources have to be automatically acquired, transmitted, archived, pre-processed and converted to a form compatible with business layer systems.
In order to cover the supervision of the equipment, personnel, materials, work in progress and other objects in non-automated production systems, it will be necessary to build an integrated system, based on automatic identification and other solutions enabling semi-automated data acquisition [9].
Summary Solutions integrating the company should provide the efficient flow of information - on one hand commands controlling the operation of production system and production orders and the tasks, and on the other – information on the execution of ordered tasks, activities of workers, flow of materials and products, problems encountered and the state of the production system.
