Natural few-layer graphene is unambiguously identified from the Chang'e-5 lunar soil samples, which serves as a new platform for investigating extraterrestrial bodies.
To compare the influences of propofol, ciprofol and remimazolam on dreaming during painless gastrointestinal endoscopy.
Masonry structures are one of the most vulnerable to severe and extensive damage in terms previous earthquakes. It is significant quickly evaluate seismic levels masonry structures, reduce casualties economic losses caused by However, traditional methods based on manual judgment or finite element simulations tend be relatively slower . In this paper, a machine learning-based rapid prediction method was proposed for assessing structures. By analysis building data from several cities combining...
The production of municipal solid waste incineration bottom ash (MSWIBA) is very massive and has the potential to replace cement despite problems complex composition, uneven particle size distribution, low reactivity. This paper adopts sodium silicate activation MSWIBA-slag improve reactivity prepare composite cementitious materials. It explores hydration performance study materials by isothermal calorimetric analysis, Fourier Transform Infrared (FTIR) spectroscopy, XRD physical diffraction...
In order to provide technical support the quality check departments, this paper researches on identification of rhinoceros horn and its substitutes. The substitutes have been respectively studied by means appearance characteristic analysis infrared spectral analysis. results show: due their similar appearances characteristics, it is difficult distinguish has two absorption peaks P-H stretching vibration sphingolipid at 2350cm-1, while other horns only one or no peak in region. What’s more,...
The content and uniformity of impurities precipitates have an important role in the efficiency solar cells made multicrystalline silicon. We developed a transient global model heat mass transfer for directional solidification silicon dynamic SiC particles nitride precipitation molten based phase diagrams. Computations were carried out to clarify distributions carbon, nitrogen oxygen on segregation particle formation during process. It was shown that precipitated solidified ingots increases...
A simple and easy hydrothermal process has been employed to synthesize flower-like ZnO products consisting of numerous orderly oriented bundled nanorods. The structure morphology the novel are characterized in detail. ZnO-nanorod-based gas sensors investigated for their ethanol-sensing properties, results reveal that exhibit a high response 143.6 1000 ppm ethanol good selectivity at optimal operating temperature 250 C. effect morphol- ogy on is also investigated.
This article puts forward the practical significance of studying complex characteristic coal logistics network from resource effective utilization and rational allocation. According to characteristics enterprises, is defined as system. Based on system theory supply chain, analysed separately complexity node structure, small word property well scale-free it pointed out that has world property.
Abstract: The study systematically analyzes the impact of various parameters such as laser repetition frequency, pulse duration, average power, water jet pressure, repeat times, nozzle offset, focal position, offset distance between grooves, and processing speed on surface morphology stainless steel. findings reveal that micro-groove depth increases with higher power but decreases increasing pressure speed. Interestingly, times have minimal effect depth. On other hand, width By optimizing...
The production of municipal solid waste incineration bottom ash (MSWIBA) is substantial and has the potential to replace cement, despite challenges such as complex composition, uneven particle size distribution, low reactivity. This paper employs sodium silicate activation MSWIBA composite Ground-granulated Blast Furnace slag (GGBS) improve reactivity in preparing cementitious materials. It explores hydration performance materials using isothermal calorimetric analysis, Fourier-transform...
This paper introduces research situation and prospect of nanoimprint lithography technology. The process three common (Such as hot press printing, UV curing stamping Micro Contact stamping) is discussed. For getting better quality, the method main factors pattern are analyzed. Furthermore, some key problems solved for purpose further understands this process. A new way thinking provided development technology in paper.
In hydraulic suspension transport, the gelled crude oil particles are known to change shape in response local flow conditions. The phase field method is used simulate deformation for particle with same internal and external fluid viscosities. For this purpose, an Image Pro Plus software records major minor axises thus, analyzes digitally its degree. Initially spheroidal droplet simulated it shown that exhibits behavior as movement final stable close oval. shear stress a time of 0.08s...
SAGD technology is utilized to exploit heavy oil in Du 84 block Shu 1 area of Liaohe Oilfield, the temperature wellhead produced fluid can reach up 170-180°C. To avoid wasting thermal energy, a set scheme cascade utilization waste heat was proposed combine generation electrical energy and heating this paper. The generating capacity, its economic efficiency are calculated analyzed scheme. In addition, taking annual total cost condenser as objective function, parameters optimized by using...
Arc sound signal in MIG welding contains plenty of information, which is an important source weld penetration. Aiming at on-line monitoring penetration, the relationship between arc and penetration analyzed time-frequency domain through a reasonable selection sample data. The results show that spectrum status are highly correlative. changes can accurately detected by variation energy from 1500 Hz to 4500 process. above experiments verify feasibility provides theory application foundation for...
In order to rescue the problems of controlling laser bionic strengthening local stripe mould surface quality, it is put forward thoughts about melting quality detection based on acoustic signal. Analyzed with relationship between defocusing distance and signal characteristic, results show that weakened increased absolute value distance. As 0mm, role primarily ablation worst; function materials too weak strengthen when -4mm; target plays its strengthening, mainly owing melting, +4mm. Overall...
Support vector machines (SVMs) are a promising type of learning machine based on structural risk minimization and statistical theory, which can be divided into two categories: support classification (SVC) regression (SVR). The basic elements algorithms SVR discussed. As modeling prediction methods introduced the experiment microwave preparing partially stabilized zirconia (PSZ) built stability model, better accuracy fitting results verified analyzed.
