A reduction of Ni concentration from 80 to 50 percent was observed as the Sm concentration increased from 0 to 25%.
Introduction Thin films of rare earth-transition metal (RE-TM) amorphous magnetic alloys are most notable as data storage media because their recording bits are free from grain boundary effects thereby, allowing ultra high areal density memory capacity.
In both read and write elements of magnetic recording heads and MRAM devices, fast switching time is becoming relevant for achieving higher data transfer rates.

Depending on the control system, a continuous dimming strategy may be able to implement relative reduction, instead of absolute reduction.
Measurement instruments installed in mechanical and electrical equipment, and power subsystem of large public buildings, can not only collect the raw data of real-time operation of equipment when the system is running, but also achieve system energy-saving operation under the control of the system software.
The course of their work is that collect the original data of power equipment running by a variety of measuring instruments, which is transferred to the energy management platform via the data connection and the transformation, and is intelligently collated by system software and Energy Plus software, and then establish the system database of efficient low-energy to run, which is integrated into energy management system software, for any large-scale public buildings to provide energy analysis, cost budget, the daily energy consumption report and financial analysis.
In addition, energy management software can also automatically store or print the data and curve of equipment operation for the follow-up system to provide complete and reliable information.
The operation data of various measuring instruments can also be directly displayed through the screen to help managers to timely detect abnormal conditions of system operation and increase the awareness of energy savings [[] Guozhang Ruan, Xiren Miao: Low-voltage Electrical Device, Vol.36(2008)No.24,p.16.

Both of these mechanisms result in hydrogen detection by Schottky barrier height reduction and current increase.
The Schottky barrier height of the diode was calculated based on the forward biasing data [10].
The observed ohmicity of Au-TiO2 junction in hydrogen atmosphere is consistent with, at least, 0.5 eV reduction in WAu due to hydrogen adsorption.
This is comparable with the reported value of 0.7 eV reduction in the work function of platinum as a result of hydrogen adsorption [16].
This interaction results in a reduction in the oxygen concentration on silver surface which in turn, reduces the SBH at the junction and increases the reverse current (Fig. 4b).

The activity data of Ni/Mo/La2O3/SBA-15 catalyst for the CO2 reforming of methane is shown in Fig. 1.
The catalyst in fresh exhibits two reduction peaks at around 490 and 790◦C.
The peaks above 200 ◦C should mainly result from the reduction of Mo or Ni ions for La containing Ni -Mo-SBA-15 samples. besides two reduction peaks at high temperature around 600 and 764◦C, a low-temperature peak emerges at 274 ◦C followed by a broad shoulder near 350◦C, that can be ascribed to the reduction of NiMoO4, less stable NiO and the other, to the first step of reduction (from Mo6+ to Mo4+) of polymeric octahedral Mo species.
Ressler[4] and co-worker concluded that the onset of reduction of MoO3 and the formation of MoO2 can be observed at 400-450◦C.The broad reduction peak centered around 600◦C can be attributed to framework Ni2+ reduction; wide reduction temperature range reflects the inhomogeneous distribution of framework Ni2+[5].

Fig. 4 Number of GBs with SIBM, NSIBM, and grain sizes in L and ST directions, dL, dST, respectively, as a function of true strain (cold reduction) prior to solution treatment in 7CN.
It was found that SIBM is marked in the cold reduction ranging from 9 to 23% although grain coarsening also takes place in this reduction range.
In the specimens with cold reductions of 11 and 16%, values are significantly smaller than that of 0% cold-rolled specimen.

Even though the long-term performance of composites incorporating physical and chemical degradation is of great importance in pipeline applications, yet the data reflecting relevant environmental conditions is still sparse [4, 5].
It was shown by Benyahia et al [6] and Bezzerouki at al [7] that he reduction of the SIF by the wrap is very significant for this crack.
This reduction is more significant as the crack angle increases.
The rate of reduction of the SIF is about 60% for the bending moment, 45% for the internal pressure and 70% for the traction.
This optimization must equilibrate between the reduction of the stress intensity at the repaired defect and the reduction of the risk of adhesive failure.

The data for the adsorption dynamics to the ammonia nitrogen are in line with the pseudo-second order kinetics equation, and the adsorption isotherme is well fitted to the Langmuir model.
Introduction With the launch of the ammonia nitrogen emission reduction task in the “Twelfth Five-Year” plan of China, the emission standards of ammonia nitrogen in wastewater are bound to be increasingly stringent, and the method of how to economically and effectively remove ammonia nitrogen from the wastewater to complete the emission reduction task is a key point of wastewater treatment.
This is to accelerate the comprehensive utilization of coal fly ash and the recycling of wastewater of the rare earth industry and provide some experimental parameters and theoretical data for domestic study and practical industrial application in the field.
Therefore, the small pores changed to large pores, resulting to an increased in pore diameter and volume and reduction in specific surface area.
The data for the adsorption dynamics of LaZP to the ammonia nitrogen is in line with the pseudo-second order kinetics equation, and the adsorption isotherme is well fitted to the Langmuir model The desorption rate of ammonia nitrogen improved with an increased concentration of NaCl solution.

The ratio, F /σ , between the load of the SP-C test (F) and the stress of the uniaxial test (σ) was determined to be 2.4 for the same value of the Larson-Miller parameter in the creep rupture data.
Details of the conventional SP test and the data analysis are given in References [1-8].
The SP-C rupture data is plotted against Larson-Miller parameter (LMP) in Fig. 6, which has been generally used for arranging the creep rupture test results under various test conditions.
In this study, the correlation between the load of the SP-C test and the stress of the uniaxial test was examined to establish quantitatively correlation between both test data.
This figure was made so that the SP-C rupture data of the aged steel were completely coincident with the uniaxial data.
