As incineratio. pro.ides a relatively safe means o. dispo.al, significant reductio. o. weight and vo.ume, and energy reco.ery fro. the waste, it was ado.ted by many co.ntries. Fo. the experimental investigatio. o. the co.bustio. characteristics o. municipal so.id waste(MSW), a lab scale fluidized bed facility was co.structed. Many kinds o. co.bustio. runs were co.ducted in this fluidized bed co.bustio. facility. The examined parameters were bed temperature(773 to.1143K), fo.m o. fuels (scrap o. who.e), mo.sture o. fuels and so.o.. Co.centratio. o. Co. 2,Co.So. 2, o. 2 and No. in the flue gas were mo.ito.ed and reco.ded every 5 seco.ds. The temperatures alo.g the reacto. are reco.ded every 10 seco.ds. Experimental results were given and analyzed.

Rigid po.yurethane fo.ms blo.n by varying water level were prepared in this study. The structures and physical pro.erties o. rigid po.yurethane fo.ms blo.n by water were measured with FT-IR, universal testing machine (Instro.3365), scanning electro. micro.co.e (SEM) and differential scanning calo.imeter (DSC). The results sho. that po.yurea and po.ybiuret were the typical charac- teristics, and the cream time and gel time were sho.ter fo. the fully water blo.n rigid fo.ms than that fo. the fully cyclo.entane blo.n fo.ms. The density o. fo.m samples decreased fro. 45.0 kg/m3 to.27.4 kg/m3 with the increase o. water level fro. 3 pph to.7 pph. Co.pressive strength exhibited the similar behavio. with density. The average cell size o. fo.m samples ranged fro. 241 μm to.356 μm with the increase o. water level fro. 3 pph to.7 pph, respectively. At the same time, po.rer dimen- sio.al stability was enco.ntered with the increase o. average cell size due to.fast diffusio. rate o. Co. o.t o. the fo.m. The results o. thermal analysis sho. that the glass transitio. temperature (Tg) shifted to.a higher temperature with the increase o. iso.yanate level when mo.e water was used as chemical blo.ing agent.

An explicit functio. expressio. fo. the bias vo.tage o./and temperature dependences o. tunnel magneto.esistance ratio.and resistances were o.tained with a unique set o. intrinsic parameters. Two.o. these intrinsic parameters are the Curie temperature TC and the density o. state (Do.) fo. itinerant majo.ity and mino.ity electro.s ξ(ρM/ρm), which are the eigen parameters o. ferro.agnetic electro.es. o.hers are the spin-dependent matrix-element ratio.(i.e., |Td|2/|TJ|2 ) and the aniso.ro.ic-wavelength-cuto.f energy ECγ o. spin-wave spectrum in magnetic tunnel junctio. (MTJ), which are the structure parameters o. an MTJ. These intrinsic parameters can be predetermined using the experimental measurement o., in principle, using the first-principle calculatio. metho. fo. an MTJ with the three key layers o. FM/I/FM. Furthermo.e, a series o. experimental data fo. an MTJ, fo. example, a spin-valve-type MTJ o.

A co.per co.verter slag was examined chemically and mineralo.ically to.determine its existing phases, in particular tho.e co.taining Co.and Cu. The slag co.sists predo.inantly o. fayalite and magnetite, to.ether with so.e glass, chalco.ite, and metallic co.per. Co.per is entrapped in the slag mo.tly as chalco.ite and metallic co.per, as well as trace co.per o.ide. There was no.indicatio. o. any independent Co.mineral in the slag, but Co.was fo.nd to.be enriched in fayalite and megnetite as so.id so.utio., altho.gh Co.was detected in all the phases o. the slag by SEM-EDX (scanning electro. micro.co.y equipped with mo.el EDAX-9100 energy dispersive spectro.eter) and WDS (mo.el WDX-2A X-ray wave-length dispersive spectro.eter).
