An important question is to indicate the position of the mechanical systems being only an element of the mechatronic structures.
The first part is analytical in character and consists in discussing elements of complex mechanical systems present in mechatronic structures.
Hence the presentation of the bearing structure and the tasks and problems related with it, such as design elements, joining solutions, maintaining the rigidity of the structure.
Within part II, the focus is on joining particular mechanical elements into complete systems, including both the bearing structure and the drive.
In the case of the bearing structure and of the drive, the focus is on using of the specific engineering knowledge within load calculations and elements selection, with the possibility of joining them.

Therefore, obtaining the composition and crystal structure of ammonium potassium chloride is of great importance for separation and purification of ammonium potassium chloride.
According to the second harmonic analysis of (NH4)1-xKxB5O8 [10] and Pb2-xSrxB5O9Cl [11], it could be determined whether they have crystal structure symmetry center.
But the composition and crystal structure of solid solution crystal has not been reported in literature.

It causes, among others, changes in polymer structure [1-4].
Silver crazes form as a result of coating structure's destruction resulting in pores and micro-fibrils forming, oriented in the direction of local deforming force's action [5].
They are released from the structure of a coating surface layer that causes real rise of its roughness [4,6].
Silver crazes consist of micropores that weaken the coating material structure changing thereby the erosive resistance of coating.

Sodium silicate was obtained from Shenyang Fangda Chemistry which module was 2.7 and the content of Na2O was 9.07%, SiO2 was 23.65%.
With polymerization been completed, Si and Al exist in the system in forms of [SiO4] and [AlO4] which constitute the basic structure.
Compact structure is developed and pores in the structure are diminished with increasing [SiO4].
However, too much [SiO4] will restrain the development of the structure for it has negative effect on polymerization and depolymerization, thus chloride diffusion coefficient increases as pores inside increased.
In the process of hydration, traditional cement of which dominated by van der Waals bond and hydrogen bond will produce pores and microcracks, therefore, structure of common concrete is not compact as that of geopolymer.

As a powerful type of quantitative structure-activity relationships (QSAR), known as 3D-QSAR, utilizes the three dimensional geometry of inhibitors in order to develop a model of the enzyme binding pocket.
So exploring the use of reliable descriptors, especially descriptors based on reasonably high level electronic structure calculations, could lead to significantly better QSAR results.

Introduction Wollastonite, a fibrous structure in the form of needle-shaped crystals, is a mineral comprising of calcium, silicon and oxygen in the form of calcium silicate or CaSiO3 [1].
After firing at 1000 oC and above, wollastonite; monoclinic structure (CaSiO3; JCPDS no. 43-1460) and gelehnite; tetragonal structure (Ca2Al2SiO7; JCPDS no. 35-0755) were the main crystalline phases.
Although the synthesized powder consists of the mixture of monoclinic structure wollastonite and gehlenite, but XRD analyses indicated that the crystalline phase of wollastonite increased with an excess content of silica.

a) a) b) b) All samples had a core-rim structure.
The elemental composition of the core-rim structure of all samples was investigated by EDX analysis.
It is evident that the grain boundary phase and the corerim structure have a strong influence on macro-hardness of LPS SiC.
In this case the grain boundaries have more 32 33 34 35 36 37 38 39 RIM RIM CORE CORE HV (GPa) Fig. 3: a) EDS analysis of core-rim structure, b) nano-hardness of core-rim structure.
The SiC grains of all compositions exhibit core-rim structure.

However, an explicit relationship between the TPA cross section and the molecular structure for the multi-branched compounds has not been established.
Therefore, synthesizing various new compounds with novel structure is helpful to understand the relationship between the cooperative effect and the molecular structure.
All calculations were performed using the Crystal Structure Analysis Package, SHELTX-97 programs.
The molecule structure was shown in fig.1.
Results shows TPEF has the similar vibronic structures to SPEF.

Therefore, LWC can be used in a wide variety of structures like walls, slabs, bridge constructions, transformer substations etc. [2].
Due to their hollow structure, they have density in the range of 600 to 900 kg/m3 [6].
Due to the hollow structure of cenospheres, considerable density reduction of LWC can be achieved by replacing silica sand with censopheres.
The first way allows to manufacture smaller and thinner concrete structures, but the second - provides producing lightweight units at the same thickness.

Later, first principles calculations confirmed BiCrO3 to be an AFM structure[13].
Below 420 K down to 7 K, a monoclinic structure is stable with C2/c symmetry (a=9.464 Å, b=5.479 Å, c=9.585 Å, β=108.56° at 7 K), and an AFM crystal structure with TN=109K[14].
