The crystalline of YSZ structure at 100W and temperature 300oC.
The crystal structure is essential for the electrical conductivity [22].
The increased grain size of the annealed YSZ electrolyte reduces the grain boundary density in the structure.
Therefore, further investigation into the effect of post-annealing on the electrolyte structure is currently underway.

The system consists of distributed data acquisition devices, a communication system based on field bus, and a host based on B/S structure.
During the long-term period of operation, the insulation strength of a circuit breaker will reduce, its electrical life will shorten, and its mechanical condition will be damaged, even it will break down, due to the influence of mechanics, hot and damp weather, high voltage, chemistry, and other environmental factors.
System Structure The data acquisition unit of the circuit breaker is based on a microprocessor, and it mainly acquires and transmits the monitoring data from the circuit breaker.
The host of the monitoring system is based on the B/S structure, namely Browser/Server structure, and the host is generally installed in the central control room of the plant where the monitored circuit breakers locate.
Therefore, its feature values will greatly change when loose, abrasion, rupture, and other abnormal events occur in the mechanical structure of the circuit breakers.

The structure, composition and morphology and electromagnetic property of the obtained samples were characterized by means of modern testing techniques.
Introduction M.X.Wan et al.[1] had reported the structure and electrical property of poly(o-toluidine) (POT) as early as in 1995.
The structure and morphology of obtained samples were characterized by means of TG-DTA, XRD, FT-IR, UV-Vis, TEM and SEM.
It was learned from Fig.1(a) that the main diffraction peaks of BFA samples in the range of 20~65° presented the characteristic of hexagonal structure, and the indices of crystal planes of each peak were consistent with standard card (JCPDS CARD 78-0133) of hexagonal structure.[9] The XRD patterns of POT doped with hydrochloric acid shown in Fig.1(c) presented two broad diffraction peaks at 13.9 ° and 24.8 ° and a weaker one at 19.1 °, which were in well agreement with the result reported by Karim et.al [10] .
Hence, POT/BFA composites showed an obvious core-shell structure, in which BFA particles were core and POT were shell.

The experimental results also indicated that PAM had a significantly adhesive effect on soil particles than EDTA,improved the soil structure to a certain role,each matrix pH value varies between 7-8, and there are no significant difference between PAM and EDTA processing matrix.
The structure of the matrix was observed by the microscope.
In this study, we use 16x4microscope observed soil structure under dry and wet two kinds of condition.
Adding appropriate red soil combined with PAM, can ameliorate the soil structure to a certain degree.

Fe2O3-C-Ni heterojunction structured composite on foam Ni was successfully prepared by simple and effective hydrothermal reaction.
The structure, ionic composition and the number of active sites were key factors determining the properties of electrode materials for electrochemical capacitors [1, 3].
The mesh structure is relatively uniform with the diameter of nanowires about 30-40 nm.
It is speculated that this structure is induced by growth of carbon microspheres.

Such reduction was achieved through a series of systematic changes and optimization in the pore's geometries by careful study, analysis, and changes in the experimental conditions such as temperature, acid concentration, chemistry of the etching solution, and time.
Certain porous Si structures have been used for gas detection as well [3].

The annealed Gd0.94-xAlxEu0.06VO4 phosphors crystallized in the tetragonal structure.
The crystal structure of the annealed Gd0.94-xAlxEu0.06VO4 powders was analyzed with an X-ray diffractometer (XRD; Rigaku RINT2000).
The patterns can be indexed as the tetragonal structure, irrespective of composition [10].
The doped Al3+ did not cause much change in the crystal structure of the phosphor powders.

SEM micrographs testified that PAFC-CPAM formed compact net structure which is different from PAFC and CPAM, resulting to its outstanding coagulation performance other than monomeric coagulant in treating oily wastewater.
Fig.3 (c) depicted CPAM on surface of PAFC that had changed PAFC crystal structure.
As can be seen from Fig.3(c), the surface structure of PAFC-CPAM came out many clumps that resembled many flowers.
From Fig.3 (d), it can be seen that every clump possessed the compact extent of net structure, which is more favorable to coagulate colloidal particles and form bridge-aggregation among flocs when compared with the branched structure [9].
SEM micrographs confirmed that PAFC-CPAM formed a new crystal structure that is different from (2) PAFC and CPAM; the compact net structure could strengthen its adsorption bridging ability and entrapment ability in treating oily wastewater

In 1971 the Spanish firm Porex Hispania registered a patent for the use of EPS as a material for lightening concrete structures.
Only fire, concentrated acids and some organic solvents may deteriorate the polymeric structure of EPS [3].
