＜正＞ In this wor. ion conductivity and FC ap.lication wer. studied for.the new typ. comp.site mater.al based on SDC （samar.um dop.d cer.a） and Li2SO4. Significant conductivity enhancement was achieved, e.g. 10-2 - 0.4 Scm-1 for.the SDC-Li2SO4 comp.r.d to 10-4 -10-2 Scm-1 for.the SDC between 400 and 650℃. Some ion conductivity mechanisms wer. p.op.sed cor.esp.ndingly. Using the SDC-Li2SO4 comp.site mater.als as the electr.lytes, we achieved high p.r.or.ances, 200-540 mWcm-2, for.inter.ediate temp.r.tur. （450-650℃） solid oxide FC （ITSOFC） ap.lications. Sulfates, typ.cally Li2SO4, have an excellent chemical stability in sulfur.containing atmosp.er.. The sulfate-cer.a （SDC-Li2SOA） comp.site mater.als can thus meet the demands to develop.the sulfur.toler.nt and H2S FC technologies, which was also demonstr.ted successfully with significant imp.r.ance for.both fundamental and ap.lied r.sear.h.

＜正＞We synthesized a ser.es of comp.site p.otocatalyst M-TiO2-xNx-WO3 （M=p., p.） by the method of temp.ate. The band-gap.ener.ies for.p.-TiO2-xNx-WO3 （2.07 eV） and ***-WO3 （1.65 eV） ar. lower.than r.tile （3.00 eV） and the best r.p.r.ed p.otocatalyst, the chemically modified n-TiO2 （2.32 eV）. The maximum absor.0}ion edge was r.d-shifted to 600nm for.p.-TiO2-xNx-WO3, and 750nm for.p.-TiO2-xNx-WO3, so they can absor. most of the visible as well as the U V p.r. of the solar.sp.ctr.m. These p.otocatalysts have good ther.al stability since the noble metals （p. or.p.） ar. located inside the comp.und p.r.icles. Under.the ir.adiation to ultr.violet and visible light, the catalysts showed good p.r.or.ance of p.otosp.itting water.to hydrogen with Na2S/Na2SO3 solution as sacr.ficial agents.

本文先后用光致发光、核磁共振和电子自旋共振研究了单晶硅中硅氢键和氢致缺陷的性质。光致发光谱表明硅氢键引起了大量非辐射中心。观测和探讨了电子自旋共振测量与样品平均厚度的关系。本文克服了真空热处理中氢从表面扩散的困难,并避免了样品平均厚度大于1.00mm和小于0.85mm给电子自旋共振带来的困难,测得分别在纯氢气氛和氩气氛生长的单晶硅每立方厘米电子自旋数。对比二者,我们估算出氢的数量为4×1016/cm7,而硅氢键分离激活能约为0.1eV。前者与文献[6]和[10]符合得很好,后者比文献[11]测定的沉淀激活能低一个数量级。
