In order to increase the sensitivity of the concentration measuring system of gas/solid two-phase flow and make the concentration measuring accuracy not affected by flow patterns, a flow pattern identification system is added for classified processing of measuring results according to the flow patterns on the basis of the original concentration measuring system. Electrical Capacitance Topography (ECT)...
Multi-layer Provisioning (MLP) of End-to-End light-path in OBS/GMPLS interworking network is successfully demonstrated by introducing extensions to MPLS signaling protocol in LOBS network. The feasibility of this mechanism was experimentally verified in an OBS/GMPLS testbed. In contrast to pervious single-layer resource provision mechanism, MLP ensures stable and high throughput of Reno TCP transportation.
The abrupt change in environment refers to the condition or state in which natural disaster, war and financial crisis etc. occur suddenly and unexpectedly. The abrupt change in environment can suddenly interrupt stability of supply chain, and bring the risk to supply chain. The elasticity of supply chain based on abrupt change in demand and price is studied in this paper. The model provided in this...
Summary form only given: A two-pulse generator for experiments on gaseous recovery in gas spark gap switches was built and tested. The generator could produce two pulses of high voltage up to 60 kV with a variable time interval between these two pulses. A time delay system of high noise-immunity was constructed to control the two-pulse generator and to synchronize the diagnostic instruments with the...
Summary form only given. Exploding wire is performed by rapidly heating the wire to vaporization temperature with a high current pulse flowing through the wire. Exploding wires have found many applications among which are the opening switches named fuses in the circuits for inductive energy storage, the discharge loads of X-pinch or Z-pinches, namely wire array Z-pinches, and the production of nanopowders...
Summary form only given. This paper analyzes the emission spectra of atmospheric microwave Ar-air plasma and He-air plasma at the range of 200 to 1000 nm; diagnoses the free oxygenic radicals of them. Results reveal that, free oxygenic radicals occupy large proportion of all elements in the spectra of Ar-air and He-air plasmas. OH free radicals are strong near the 309-314 nm band compared with He...
Summary form only given. As a highly intensive and subnanosecond pulse X-ray point source, X-pinch plasma could find many potential applications. A pulsed power generator (500 kV, 400 kA, 100 ns) was constructed and used as the power source of an X-pinch. The X-pinch load was made of two 25-??m Mo wires. The temporal and spatial X-ray emission from the X-pinch was studied by using diamond photoconducting...
Summary form only given. The experiment of dielectric barrier discharge in a 2-mm air gap shows that the pressure range of a uniform discharge using polytetrafluoroethylene as barrier is much wider than that using quartz or alumina. The parameters of the charge trapped on the surface of these three dielectric barriers were obtained by surface charge measurement and thermally stimulated current measurement...
Bismuth sodium barium titanate [(Bi0.5Na0.5)0.94Ba0.06TiO3 or BNBT6] ceramic powder have been incorporated into a polyvinylidene fluoride-trifluoroethylene [P(VDF-TrFE) 70/30 mol%] copolymer matrix to form 0-3 composites. With the composition near the morphtrophic phase boundary (MPB) region, BNBT6 has relatively high piezoelectric properties. Polyvinylidene fluoride-trifluoroethylene [P(VDF-TrFE)]...
Summary form only given. It was known that one of the most important characteristics of plasma focus is the abundant amount of neutrons that are produced when deuterium is used as filling gas. This paper presents the studying results on neutron emission characteristics. A 2.2 kJ small repetitive plasma focus device was developed and its pulsed current and quarter period are 210 kA and 1.5 mus. Among...
Piezoelectric transformer (PZT) is a device which transforms voltage by piezoelectric effect and converse piezoelectric effect of ceramic material. Compared with electromagnetic transformer, it has favorable characteristics of miniaturization, electromagnetic-noise free and the variable voltage gain with frequency and impedance. The modeling of piezoelectric transformer is the base of control and...
