This paper introduces use of high frequency(HF) and ultrahigh frequency(UHF) in partial discharge test on HV cable terminals.UHF test system is used for preliminary test,then various signal detection modes are adopted to sample measured signals from cable terminals for in-depth measurement of HF.The measurement obtain…
The effects of two kinds of water-soluble silver salt(silver nitrate or silver acetate) on heating behaviors,bulk resistivity of ECAs and contact resistance of ECAs on tin surfaces under aging condition were investigated.The DSC results show the addition of silver salt does not influence curing behaviors of ECAs.The b…
Zinc doped Li(Ni1/3Co1/3Mn1/3)O2 cathode materials for lithium-ion batteries are synthesized by co-precipitation method.The first delithiation of the samples are studied by electrochemical impedance spectroscopy(EIS).The fitting results on EIS data indicate that the cathode delithiation is at 3.7~4.4V voltage range;th…
Using the high micro-Raman spectroscopy,the micro-structures of nonlinear optical crystal LiB_3O_5 and its high temperature solution were studied.The high temperature Raman spectra of LiB_3O_5 crystals,Raman spectra of lithium borate glasses Li_2O·4B_2O_3 at room temperature and its melt at high temperature were obtai…
Prepared B4C/AZ61 magnesium matrix composites by mechanical mixing method and analyzed how the B4C particles effect the creep and wear properties of AZ61 by comparing with the creep and wear test results of AZ61 matrix alloy and B4C/AZ61 magnesium matrix composites.The results show that: for the creep properties,the m…
The carbon footprint calculation processing is studied based on a real case of cotton wet process,in which all the inputs and outputs data of the whole dyeing and finishing process of black cotton-spandex weft elastic satin drill is collected.According to the pad-dyeing practice,black cotton-spandex weft elastic satin…
Ni nanowire arrays were synthesized using two simplified template-based electrochemical methods,in which a home-made porous anodic aluminum oxide(AAO) membrane and a commercial Cu-foil-AAO template were used as the template.The length of the prepared Ni nanowires is in micrometer scale while their diameters are 50nm a…
To study the influence of DMQA concentration on the performance of OLEDs,the devices of ITO/PEDOT: PSS/TPD/Alq3: DMQA/LiF/Al with the doping ratio ranging from 0.28 wt% to 4.5 wt% were investigated.When increasing the DMQA concentration,three phenomena were observed: the current characteristics decreased slightly,whic…
A series of Cu-Mn nanocomposite oxides is prepared by hydrothermal synthesis.The products are characterized by XRD,SEM and H2-TPR.The catalytic performance of the selective catalytic oxidation of benzyl alcohol is investigated.The results show that when the molar ratio of Cu and Mn is greater than 1,the products are c…
Objective This study was designed to investigate the anti-obesity mechanism of recombinant human ciliary neurotrophic factor(rhCNTF) in the Neonatally Monosodium Glutamate-Treated Obesity model rats and to provide the experiment data for the development of rhCNTF as a new drug.Methods MSG rat model was established in…
Through different water deficit treatments,the cumulative function of water sensitive index for cotton was established in this paper.The higher water sensitive index was in the period of 90-110 day after seeding and can reach 0.025.The results demonstrated that the cumulative function of sensitive index represented by…
Aluminum alloys,treated by chrome-free chemical conversion in titanium salt were powder coated.The adherence property,the corrosion property and the mechanical property of the powder coatings were tested according to related standards.The results showed that the properties of chrome-free chemical conversion coatings,e…
Isophorone diisocyanate was first reacted with bis(3-(1-methoxy-2-hydroxypropoxy) propyl) terminated polysiloxanes(PMTS) to attach cyanate groups to polysiloxane chain terminals,followed by reaction of these cyanate-containing polysiloxanes with poly(propylene glycol) to get polysiloxanes modified polyurethane prepoly…
Objective To approach genetic diversity of Cynanchum otophyllum among populations,within population and seeds.Methods AFLP molecular markers were used to analyze the genetic diversity among populations in different ecological environments,different plants,and different seeds of twins follicles.Results The results show…
This paper discusses the rolling force measurement of strip rolling mill.The results not only provide materials for the practical production,but also a practical basis for the study on the strip rolling mill concerned at present.
To improve the heat processing parameters in cold-punching mold manufacturing with high-speed steel W18Cr4V,the quenching temperature,tempering temperature,tempering times and influence of the volume of retained austenite on surface hardness and roughness of the material are researched.The results indicate that the vo…
