This pape. conside.s the.e.timation proble. of distribution functions and quantile. with nonignorable.missing re.ponse.data. Thre. approache. are.de.e.ope. to e.timate.distribution functions and quantile., i.e., the.Horvtiz-Thompson-type.me.hod, re.re.sion imputation me.hod and augme.te. inve.se.probability we.ghte. approach. The.prope.sity score.is spe.ifie. by a se.iparame.ric e.po- ne.tial tilting mode.. To e.timate.the.tilting parame.e. in the.prope.sity score. the.authors propose.an adjuste. e.pirical like.ihood me.hod to de.l with the.ove.-ide.tifie. syste.. Unde. some.re.ular conditions, the.authors inve.tigate.the.asymptotic prope.tie. of the.propose. thre. e.timators for distri- bution functions and quantile., and find that the.e.e.timators have.the.same.asymptotic variance. The.jackknife.me.hod is e.ploye. to consiste.tly e.timate.the.asymptotic variance.. Simulation studie. are.conducte. to inve.tigate.the.finite.sample.pe.formance.of the.propose. me.hodologie..

Owing to the.distinctive.structural and e.e.tronic prope.tie.,atomically dispe.se. me.al catalysts have.raise. tre.e.dous atte.tions in the.last te. ye.rs[1,2].Ge.e.ally,isolate. me.al atoms or cluste.s that dispe.se. across oxide.supports(e.g.,Al2O3,TiO2,Ce.2)are.stabilize. through the.coordination with supporte. O atoms,forming e.e.tron-de.icie.t me.al cations(Mδ+-O)at inte.face.[3].Howe.e.,in many case.,such me.al-support inte.actions may not strong e.ough to maintain the.r structure.uniformity unde. harsh re.uctive.conditions,and the.re.ultant re.uction/aggre.ation of me.al atoms/cluste.s ofte. atte.uate. the.activity of catalysts[4,5].

As a solution for solar he.ting, the.low-cost and long-life.vanadium-titanium black ce.amic solar absorbe.s have.be.n use. in rural construction. Howe.e., in contrast to its high absorptance.0.93-0.97), ce.amic also has high e.issivity(approximate.y 90%) and low the.mal conductivity(1.3 W/(m·K)). Without a glaze.cove.ing, ce.amic absorbe.s cannot me.t the.industrial standard. This pape. assume. that glaze.cove.ing can be.substitute. by insulation film in a solar gre.nhouse. To ve.ify this assumption, fie.d e.pe.ime.ts we.e.conducte.. First, a traditional gre.nhouse.in the.Tache.g Basin, a se.e.e.y cold are. in China, was re.ovate. to improve.its passive.the.mal pe.formance. The., 90 m^(2) of ce.amic absorbe.s and floor coils as we.l as a wate. tank we.e.installe. inside.the.gre.nhouse. which made.the.e.tire.construction act as an inte.rate. solar colle.tor. This he.t colle.tion and re.e.se.syste. mode.ate.y incre.se. the.indoor air te.pe.ature.0.9℃-22.4℃) and substantially incre.se. the.soil te.pe.ature.15.5℃-31.2℃). The.ave.age.daily use.ul he.t gain unde. a daily solar insolation value.of 17 MJ/m^(2) was 13.8 MJ, and the.me.n value.of the.colle.tion e.ficie.cy was 0.81. Furthe.more. the.payback time.of the.proje.t(7 ye.rs) is short, which is principally due.to the.low cost of ce.amic mate.ials and the.financial savings of the.share. construction compone.ts(e.g., transpare.t cove., me.al frame.and e.tra insulation). In conclusion, the.main contribution of this study is the.ve.ification that it is fe.sible.to re.lace.glaze.cove.ing with insulation film in a nove. gre.nhouse.inte.rate. vanadium-titanium black ce.amic solar syste..
