Introduction The ternary Ce-Rh-Si system comprises a huge number of compounds crystallizing in different structure types with a broad spectrum of properties [1].
But the difference between measured and calculated spectra evidences a number of weak additional peaks, pointing to the presence of foreign phases, which are likely also the cause of the larger reliability factors.
The high RR ratio ρ(300 K)/ρ(2 K) = 31 indicates a low defect concentration in the main phase, suggesting that the comparatively high paramagnetic impurity content deduced from χ(T < 2 K) origins from grain boundaries.
Taking into account the sizeable number of atoms per formula unit, γ is not very large, indicating the mass enhancement due to VF to be rather small, in accordance with the high energy scale of these VF.
Analysis is complicate by the fact that Vcf increases not only upon decreasing distances, but also upon increasing number of ligands.

Co-simulation applications based on the second method is more common, it is based on a simulation model based on different disciplines, different professions, different simulation environment and heterogeneous platform for the main part of the simulation model using different propulsion mechanism to carry out run distribution of real-time interaction, comprehensive, fine-grained simulation job.
Has the following three advantages of multidisciplinary collaborative simulation method based on the interface The overall understanding and grasp of the aerospace system: the complex system of aerospace systems, co-simulation technology complex system can be divided into a number of sub-systems System, and enhance the robustness of the system, the modeling and simulation work easier analysis and control, easier to understand the values obtained in the simulation.
Federal initialization phase, the first to start the implementation of the RTI server RtiExec procedures, the program enters the monitoring state, the next general federate process FedExec, federal managers to create a good communication channel by prior agreement to establish contact with RtiExec, The registered host IP and port number, and other information.
And other federal request to join members to managers, managers, record information about members of the federal entity number of categories, such as members of the simulation, and on the outside of the corresponding.

Results and Discussion The microstructural analysis of both states of austenitic steel shows that the austenitic structure is formed by polyhedral grains of austenite of different sizes (Fig. 2).
There is a large number of inclusions in the microstructure and it is possible to monitor the presence of annealing and deformation twins.
The structure contains a large number of MnS-based non-metallic inclusions (Fig. 3).
The opposite results were obtained by Çetinarslan et al [12], who found that non-nitrided specimens withstood a higher number of cycles than specimens after nitriding.
After the three-point bending fatigue test, the nitride sample had a higher number of cycles.

The coarse aggregate was crushed basalt with the maximum grain size of 20 mm.
So the characteristic peak of C-O functional group in wave number range of 1375-1520 cm-1 could be used to determine the carbonation profiles of concrete samples [13].
The profile of CaCO3 was determined from the position of C-O peaks corresponding to the baseline at wave-number 1400-1510 cm-1.

But, the opportunity of the droplets getting together is very much , and form these ,wo can see that the impact can homogenize droplets and make the particle size distribution narrow which means that in the process of the impact tiny drops of grain tends to get together.

Each defect has its corresponding defect level, and the defect type determines the position and number of emission peak, but concentration determines the peak intensity.

There is a number of mid-low grade phosphorite waiting for development and utilization.
The one is the collophane encase fines, fine grain impurity inclusions; another is collophane and gangue always with metasomatism and they are always connect; and the third is that some collophinite is finely disseminated by iron and carbon clay.

The microstructure of the cladding tends to grain refinement with its inhomogeneity improved with increasing scanning speed. meanwhile, average microhardness increases,When scanning speed is low, the laser input energy is higher, lead to coating microstructure is bulky, the microhardness decreased.
Fig. 2 Micro-hardness of the coating at various scanning speeds Conclusion (1) The coatings of laser cladding were constituted by cladding zone (CZ), bonding zone (BZ) and heat affected zone (HAZ).The microhardness of test samples cross section results showed that it presented a good transition from substrate to coating surface.The coatings of laser cladding with high hardness is due to the in situ reaction caused by a large number of reinforced phase.The hardness was increased greatly which after Laser hardening.
