Effects of Al and La elements on mechanical properties CoNiFe0.6Cr0.6 high-entropy alloys (HEAs) with face-centered cubic (FCC) structure were investigated by first-principles calculations. The variation curves relevant physical parameters, including lattice constants, formation enthalpy, elastic modulus, Poisson's ratio, Pugh's Cauchy pressure, anisotropy factors, Vickers hardness, yield strength, energy factor, as a function concentration discussed in detail. Results show that the...
Resonant converters are widely used in high voltage applications thanks to the soft switching technologies. The frequency and (HFHV) transformer is most complicated important part boost by tens or hundreds of times, parasitic capacitance transformers critical performances resonant converters. To reduce capacitance, multi-section winding technique usually employed HFHV transformers. However, values calculated classical methods not consistent with experimental results transformers, they...
The successful operation of the gyrotron strongly depends on proper alignment with magnet. difficulty will increase as frequency becomes higher, especially for terahertz pulsed gyrotron. In this article, we describe an easily implemented method in detail. A triaxial adjusting flange was designed to align can be identified by fluorescent effect electron beam sapphire output window, which captured triggering a charge-coupled device camera. affine transformation also used correct distorted...
This article proposes a technique of flat-top magnetic field for the goal high-frequency gyrotron with pulse duration several hundred milliseconds. A 14.8-T pulsed magnet is designed an 800-GHz second harmonic gyrotron. The energized by battery bank bypass circuit to achieve 620-ms duration. To fulfill requirements and power supply, genetic algorithm NSGA-II has been used in multiobjective optimization distribution dissipation magnet. Helix layered reinforcement introduced address problems...
With the green building research rising in these years, rational mode of human beings and nature China traditional architecture, which contains rich experience about ecological design, should be re-examined. The design strategies neo-vernacular is also becoming more important so we have to pay real attention to. This article demonstrates an integrated ecosystem approach a process architecture called Xijie hope providing certain reference help for similar study.
A triple-coil pulsed magnet aiming at 100 T (Tesla) was designed and tested the Wuhan National High Magnetic Field Center. The powered by a MJ pulse generator, battery bank, 25 kV capacitor banks in combination. failed 83 T, while whole structure remained intact. failure process analyzed using recorded waveforms of voltage current, as well disassembling dismantling magnet. It shows that inner coil broke down first, then electrical breakdown occurred between middle outer coils. possible...
China is facing an important period of rural governance innovation and restructuring territorial spatial patterns. This paper selects catchments as the most closely related units for industrial development settlement activities, profoundly revealing characteristics transformational in mountainous areas. To date, extensive literature this area has produced a broad multidisciplinary consensus on catchment water soil conservation industry development; however, interactive mechanism ecological,...
Ultra-high-frequency (UHF) technique for detecting partial discharge (PD) phenomenon is a useful method to avoid insulation accidents in gas insulated switchgear (GIS). However, the circumferential angle position of UHF Sensor GIS has great effect on PD detection, which not been investigated sufficiently. To deeply investigate propagation characteristics signal and improve application technique, influence studied by performing several experiment tests this paper. Applying two-arm equiangular...
A modified mechanical model for the stress analysis of solenoid pulsed magnets is presented, which includes influence bending on plane analysis. The effect in axial direction included by introducing discrete strain with assumption uniform distribution force load. improves accuracy remarkably compared to classical Generalized Plane Strain (GPS) results are verified FEA software. algorithm identifying optimum positions separations between windings also proposed. This achieves both high...
Nonsequential double ionization of He atom in the combined field a laser and static electric has been investigated. It is found that presence breaks inversion reflection symmetry, symmetric double-peak structure He2+ ion momentum parallel to polarization broken. Since ultrashort pulse similar asymmetric character, this study helpful understand mechanism process field.
This paper presents a method to maintain the output voltage constant under variable load resistance for ICPT power pick-ups. A phase-controlled inductor is dynamically swithched detune/tune resosant circuit according of pickup. Variations open and degraded resonance capacitor caused by high temperature are compensated controlling conduction delay angle with deliberately designed resonant parameters. The effect equivalent inductance on flow analyzed theoretically fundamental component ac...
The high-frequency method for solving the scattering of electrically large coated targets in half space is presented this paper. In order to consider influence environment, half-space physico-optical integral equation deduced by introducing Green's function into method.

The academy is a type of building which combines the function academic communication and ritual worship in ancient China.The construction academies Jiangxi Province Yangtze River valley South Area China was among forefront Chinese history.The are complete architectural form well preserved.This paper focuses on analysis spatial pattern Province, discusses space method, finds out essence order to provide basis reference for follow-up study.
The relationship between med-long term load forecasting and socio-economic indicators is very difficultly described by an accurate mathematical model. So needs to dig out few dominant factors from lots of indicators. By introducing data mining technology into the association analysis China's electricity consumption growth, many since 2000 are selected constitute relevant database. To complement a missing data, number closely related dug cluster analysis, distortion corrected, thus, more...
