Proper orthogonal decomposition is used to study structure pump for advantages turbulence analysis. Further, complex vertical single-stage marine pumps have studied, relationship between energy distribution...
Abstract The intramolecular hydrogen‐bonding interactions and properties of a series nitroamino[1,3,5]triazine‐based guanidinium salts were studied by using the dispersion‐corrected density functional theory method (DFT‐D). Results show that there are evident LP(N or O; LP=lone pair)→σ*(NH) orbital related to O⋅⋅⋅HN N⋅⋅⋅HN hydrogen bonds. Quantum atoms in molecules (QTAIM) was applied characterize For studied, bonds associated with seven‐ eight‐membered pseudo‐ring. guanylurea cation is...
With a gradual increase in coal mining depth, the underground geological situation is more complex and threat of rock bursts prominent due to cross influence multiple factors, such as faults, thick hard roofs, pillars, high situ stress areas. Additionally, it difficult test effectiveness pressure relief measures after implementation areas with burst dangers. By evaluating geology conditions panel 5308 Tangkou mine, prevention control technology, combining pre-pressure danger measure, was...
Because it is difficult to measure the on-line apparent degree of calcination in New Suspension Preheater Dry Process (NSP) cement production line, a soft sensor model established by using technique and Least Squares Support Vector Machine (LS-SVM) with RBF kernel. The furnace temperature pressure calciner, outlet tertiary air lay off quantity raw are used as inputs model. output. A realization scheme programmed VC ++ based on DCS OPC presented. results experiment show that prediction...
In this study, a set of designed 2,4,6-trinitropyridine N-oxide (TNPyO) derivatives with different substituents were studied theoretically at the B3LYP/6-31G* level density functional theory. The gas-phase heats formation (HOFs) predicted based on isodesmic reactions. condensed-phase HOFs and sublimation estimated in framework Politzer approach. crystal densities computed from molecular packing which are confirmed to be able produce good estimation for TNPyO comparison available experimental...
In view of the urgent need for safety performance braided wire ropes in power grid construction, this study analyzes mechanical responds a rope under tension and torsional loads. The strands tension, torsional, tension–torsion loads are studied, response equations above obtained. Furthermore, respond model is established using method strand unfolding. strain axial direction used to determine rope. stress expressions whole tensile–torsional load test carried out, displacement curve same...
Filling mining is a main technology of coal resources under buildings, and it has good effect on preventing ground subsidence. Taking Wangtaipu mine the Shanxi Jincheng Anthracite Coal Mining Group as engineering background, in order to solve problem traditional closed brick wall at end working face, which consumes lot manpower material resources, low efficiency, rapid-molding in-closed retaining-wall was proposed. Through theoretical analysis analogy, overall structure size mold bag were...
Abstract Ninety‐one nitro and hydroxyl derivatives of benzene were studied at the B3LYP/6‐31G∗︁ level density functional theory. Detonation properties calculated using Kamlet‐Jacobs equation. Three candidates (pentanitrophenol, pentanitrobenzene, hexanitrobenzene) recommended as potential high energy compounds for their perfect detonation performances reasonable stability. The pyrolysis mechanism was by analyzing bond dissociation (BDE) activation ( E a ) hydrogen transfer (H–T) reaction...
Soft sensor technique is used to solve the problem of measuring on-line apparent degree calcination in New Suspension Preheater Dry Process (NSP) Kiln based on BP neural network this paper. According actual working conditions calcinations, a soft model with six Dimensional input vector and one output established by using Back-Propagation (BP) network. The Reliability prediction accuracy are verified compared data. results experiment show that can reach 96%. So measurement NSP be realized model.
The mechanic properties mainly the room temperature bending strength and creep of Al 2 O 3 ceramic specimens which were prepared by cold isostatic pressing had undergone different thermal histories have been measured compared. results suggest that increases after high soaking. can withstand cyclic rapid cooling with an initial 200 °C. sample has shown a very good dimensional stability long service time (50h) at 1550
Aiming at the problem that existing virtual assembly interfaces lack scenario analysis capabilities and can't effectively perceive user's intentions, scene knowledge model user are proposed in this paper. We establish base database according to respectively. To solve ambiguity of intention interaction, expert system uncertain reasoning is used for understanding specific semantics actions. The innovations work include: (1) we construct separately. combine closely build rule base, (2) because...
The implementation of user's interactive goal is completely dependent on the recognition rate gesture in smart TV's interaction. This increases load. So we propose an implicit interaction algorithm for TV based context. Firstly, implement data's fusion and feature's extraction Then, designed model(MLC-FCM) which Finally, MLC-FCM used to realize perception intention complete task. can improve accuracy operations, reduces time spending gesture's movement distance.
Underground coal resource excavation has caused a series of geological disasters and environment problems. Backfill-strip mining combined the advantages strip backfill can reduce subsidence, improve recovery rate resources.
