Steel E690 used in oceanographic engineering were direct-quenched and tempered at different temperatures under rapid heating by using a Gleeble-3500 thermo-mechanical simulator.Effects of different tempering temperatures on microstructure,precipitation and micro-hardness of the steel were investigated by means of opti…
The acceleration test recorder,which records the process of missile's penetrating the earth target,was studied.The design theory of internal test memory circuit was proposed.A shell of medium thickness was designed to protect the circuit.The experiment method was proposed to determine the thickness of the aluminum foa…
New natural cellulose fiber,with the advantage of environmentally friendly and biodegradable performance is bound to become an important part of future textile materials.This paper introduces the properties of several new types of cellulose fibers such as banana fiber,bamboo fiber,cotton stalk skin fiber,pineapple fib…
In this study,WC-10Co4Cr coating is used to protect AZ91D Magnesium alloy by JP-5000 high velocity oxy fuel(HVOF).In order to study the effect of spray parameters at interface between the surface of AZ91D Magnesium alloy and the coating,the SEM,EDS,XRD and other analytical methods were used for material structure and…
Stearic acid and two silane coupling agents were used on the surface modification of wollastonite.The effect of different modifiers and content of modified wollastonite on mechanical properties of the EP resin were studied.The impact fracture surface of the wollastonite toughing EP composite was also analyzed.The resu…
PbLa(ZrSnTi)O3 relaxor antiferroelectric single crystal was grown by the flux method.The domain structure was observed by the polarizing microscope.Two kinds of domain structures on the(001) face of PbLa(ZrSnTi)O3 single crystal were observed.There are antiferroelectric domains along and direction,and polar sub-domain…
Only SNCR process is suitable for circulating fluidized bed(CFB) boiler’s NOx emission reduction,its NOx initial discharge is much lower than other type of furnace,due to its low bed temperature,staged combustion.But if the implementation of the new standards of environmental protection,some CFB boiler can not meet th…
Water dispersion of magnetite(Fe3O4)affects its applications in biomedicine.Highly Water-Dispersible Fe3O4 has been prepared by hydrothermal method using FeSO4,EG and trisodium citrate.The phase,morphology,size and surface functional groups were characterized by X-ray powder diffraction(XRD),scanning electron microsco…
Validoxylamine A modified amphiphilic polymer networks(VACMPS) were prepared from the amination reaction of macroporous crosslinked chloromethyl polystyrene(CMPS) with validoxylamine A.The structure of the new adsorbent was evaluated through analysis of the residual chlorine content,BET specific surface area,and FT-IR…
This paper analyzed the texture synthesis’s classical algorithms based on sample,and study the advantages and shortcomings of each algorithm.In order to realize better results,texture synthesis,proposed improved Texture Synthesis based on Wang Tile,algorithm will look for the smallest error path method is applied to t…
Cell suspension turbidity(optical density at 660 nm,OD660 nm) was measured using an automated growth curve analyzer to investigate the growth of Bacillus subtilis natto during incubation in a liquid culture medium composed of soybean meal as nitrogen source and glucose as carbon source.The optimal concentrations of so…
Through the uniformized annealing,the step quench,quenches under the medium and different temperature quenching differently,the tempering,the effectiveness and the electrochemistry experiment,Unifies the DSC curve test,scans the electron microscope and the polarization curve,the impedance curve and so on the analysis,…
In the paper,two isolates of pathogen of plantain head blight from Ji'an county in Jiangxi province were molecularly identified.RDNA-ITS region of each of the two isolates was amplified by PCR,and the PCR products were sequenced.Both of them are 579 nt in length,and they have a consensus sequence.The sequence shares 9…
This paper introduced briefly preparing process of powdered aluminum-base filler metal,researched the technical performance of powdered aluminum-base filler metal.Proceed from the surface tension,discussed affects of powder sizes,oxygen content,heating velocity,heating homogeneity,ratios of filler powder and flux on t…
Multi-walled carbon nanotubes(MWCNTs)were oxidized with mixed acid,and then were functionized with phosphorus-containing compound 2-(6-oxido-6,H-dibenz c,e l,2 oxa phosphorin-6-yl)-1,4-dihydroxy phenylene(DOPO-HQ).The functionalized carbon nanotubes(MWCNTs-P)were used to modify epoxy resin.The effects of MWCNTs and MW…
The effect of ultra-fine fully vulcanized powdered styrene-butadiene rubber(UFPSBR) on the properties of NR/SBR/BR tread compound was investigated.The results showed that,compared with the tread compound without UFPSBR,the NR/SSBR/BR tread compound with 2~3 phr UFPSBR had lower tensile strength,better wear resistance…
