With the arrival of the Internet and information age,the traditional professional market has been facing a hitherto unknown challenge.As a professional market which leads in transforming and upgrading children's markets,the China Children Garments Market needs to complete its own transformation under the backgrounds o…
Thermoplastic rubber(TPR),is generally called as artificial rubber.In this task,SBS,antioxidant 1010,Liquid Paraffin 15# and 145# rosin pentaerythritol ester were used as raw materials to prepare TPR.On that basis,TPR gel matrix patch was prepared containing camphor,the camphor leached to ethanol was detected by GC.Th…
Surface flashover phenomena in vacuum often occur along the insulator,with its onset flashover voltage much lower than the breakdown voltage of either the insulator or the vacuum gap with the same length,so it seriously limits the development of high voltage electro-vacuum devices.Introducing a kind of machinable cera…
Using carambola as raw materials,fresh-cut carambola was processed by ascorbic acid combined with chitosan,and the physiological and biochemical changes of fresh-cut carambola were studied in this paper.The results showed that 6 g/L ascorbic acid combined with 15.0 g/L chitosan had a significant role for fresh-cut car…
The changes in the nature of trapped solution in Yingtan acid soil simulation solution were in-situ measured with rectangular disbonded model,and the simulated trapped solution of early and late corrosion were matched.The properties of the solutions were analyzed by potentiodynamic polarization curves,electrochemical…
The effects on the molybdenum alloy powder properties,sintering proceeding and sintering products density and mechanical properties of molybdenum alloy as-worked wire which was doped with rare-earth oxides particles such as La 2 O 3 、Y 2 O 3 、CeO 2 were studied.The results showed that the particles size of the molybde…
Atomic force microscope(AFM) was uesd for detecting collagen and its natural assembly structure, as well as the typical collagen assemblies formed in vitro. The ability and suitability of AFM in detecting collagen and its assemblies were summarized. The sample preparation and the optimized detection process were discu…
In order to obtain the factors affected flue gas desulfurization of activated coke,the simulated experiment of flue gas desulfurization was carried out in a fixed-bed adsorption column packed with activated coke made by our laboratory.The authors studied the influence of bed temperature,oxygen concentration,steam conc…
In order to understand function of serine protease inhibitor 5(Serpin-5) in silkworm(Bombyx mori),we prepared its polyclonal antibody and analyzed its expression pattern in various silkworm tissues.We first cloned and obtained the Bombyx mori serpin-5 gene without signal peptide.This gene is 1 140 bp long and encodes…
In order to realize the forming of a titanium alloy taper,direct extrusion forming process,two-stage extrusion forming process and composite extrusion forming process were designed.The forming loads and production efficiency were contrasted by analysis of Deform finite element software.The best extrusion forming proce…
Objective To explore the lung injury caused by rare earth neodymium oxide( Nd2O3) particles in rats. Methods Seventy-two wistar rats were randomly divided into 4 experimental groups: a control group and 3 Nd2O3treated groups( 25. 0,50. 0 and 100. 0 mg/kg). Disposable non-exposed type intratracheal perfusion was adopte…
In the present study,immobilization technology of recombinant Escherichia coli cells producing Thermobifida fusca glucose isomerase was studied using chitosan flocculation and glutaraldehyde cross-linking methods.In order to obtain the immobilization method for GIase with high performance and low cost,various factors…
This paper introduced the test principle and superiority of testing ON/OFF potential and PCM leakage of electricity to evaluate insulation performance of insulated joint for in-service pipeline.The test data indicate that insulation performance of insulated joints can be quantitatively evaluatedreliably,based on these…
The impacts of monoglyceride addition on interface emulsifier concentration,protein concentration in liquid phase,particle size distribution,partial coalescence of fat and centrifugal creaming ratio in a model emulsion stabilized by casein were studied.The possible mechanisms were also revealed.The results showed that…
In order to determine the impact of front cover fragmentation of the packaging launcher on warhead fuze crashing trigger switch and turbine generator when an individual rocket was launched,the LS-DYNA software was used to simulate the process of front cover crash through compressed air pressure and pushed to break whi…
The effects of the blending ratio of chlorinated paraffin/antimony trioxide,use of carbon black and silica on the combustion characteristics and smoldering property of flame-retardant SBR were investigated.The results showed that,when the blending ratio of chlorinated paraffin/antimony trioxide was 1∶1,the flame-retar…
Two new one-dimensional chain complexes,(NH4)2[Cu(NH3)2(CrO4)2](1) and(NH4)2·[Ni(NH3)2(CrO4)2](2),were obtained by mixing copper nitrate or nickel nitrate with the same molar of ammonium dichromate in ammonia water at room temperature,and they were characterized by single-crystal X-ray diffraction(XRD),thermogravimetr…
The production process of chloroprene rubber via calcium carbide route is sketched.The construction investment in 30 kt/a chloroprene rubber project via calcium carbide route,its consumption quota and economic benefits are estimated.This project has strong profitability and anti-risk ability,and is worthwhile for chlo…
Under conditions of low temperature SCR reaction,the effects of SO2 on the SCR activity of Mn/TiO2 and Mn-Ce/TiO2 catalysts as well as its mechanism were investigated in detail in this paper.It was found that Mn/TiO2 catalyst would deactivate quickly in the SO2 reaction atmosphere.The deposition of ammonium sulfate sp…
Polyhedral oligomeric silsesquioxanes(POSS) had a compact hybrid structure with an inorganic core made up of silicon and oxygen,which was used in the development of a wide range of hybrid nanomaterials with diverse properties.Hybrid organic/inorganic polymer systems by incorporating dispersed POSS into traditional org…
