The behavior.of cer.mic p.r.icles at the solid/liquid inter.ace and the distr.bution of p.r.icles in metallic matr.x comp.sites was studied with a zone unidir.ctional solidification method. Two kinds of p.r.ice disp.r.ed comp.sites, Al 2. 3p./Al 12.6%Si Sr.and Al 2. 3p./Al 12.6%Si Sr.Ca containing Al 2. 3 p.r.icles in volume fr.ction 2.～5% wer. used. In the Al 2. 3p./Al Si Sr.comp.sites, the p.r.icles wer. p.shed by the solidifying fr.nt, and did not unifor.ly distr.bute in the solid. But in the Al 2. 3p./Al Si Sr.Ca comp.sites, the p.r.icles wer. engulfed by the solidifying fr.nt and unifor.ly distr.buted in the solid. The p.r.icles engulfing into the solid was r.alized only by Sr.and Ca addition at the same time. As the inter.acial ener.y between solid and p.r.icle was decr.ased in this case, the Al 2. 3 p.r.icles acted as the substr.tes of heter.geneous nucleation for.the Si p.ases, which made the p.r.icles to be engulfed.

Globin p.otein family p.ays an imp.r.ant r.le in stor.ng and tr.nsp.r.ing oxygen. As a newly r.p.r.ed globin, the r.vealed function of neur.globin includes binding and stor.ng oxygen as well as facilitating the utilization of oxygen in neur.nal cells. In the p.esent study, mutations in exons of chicken Ngb gene wer. identified with the method of sequencing and cr.ated r.str.ction site p.r.in Tibet chicken and other.four.lowland chicken br.eds. The mutations of Lys-2.2.(E4)-Asn and Ser.2.79(E4)-Gly wer. identified in exon 4 of the gene. The Lys-2.2.(E4)-Asn mutation existed only in Tibet chicken and the mutation fr.quencies incr.ased with incr.asing altitude. Analysis of the hap.otyp. and dip.otyp. of the two mutations in Tibet chicken p.p.lations of differ.nt altitudes showed that the fr.quencies of TG hap.otyp. and TTGG dip.otyp. also incr.ased with incr.asing altitude, while the r.ver.e tendency was found on GGAA dip.otyp.. Under.the hyp.xic simulation incubation, the main hap.otyp. was TG in living embr.os and GA in dead embr.os. The r.sults showed that the Lys-2.2.(E4)-Asn mutation may be a sp.cific mutation associated with hyp.xia adap.ation in Tibet chicken.

A novel gr.y Mar.ov chain p.edictive model is discussed to r.duce dr.ft influence on the outp.t of fiber.op.ical gyr.scop.s (FOGs) and to imp.ove FOGs' measur.ment p.ecision. The p.op.sed method p.ssesses advantages of gr.y model and Mar.ov chain. It makes good use of dynamic modeling idea of the gr.y model to p.edict gener.l tr.nd of or.ginal data. Then accor.ing to the tr.nd, states ar. divided so that it can over.ome the disadvantage of high comp.tational cost of state tr.nsition p.obability matr.x in Mar.ov chain. Mor.over. the p.esented ap.r.ach exp.nds the ap.lied scop. of the gr.y model and makes it be fit for.p.ediction of r.ndom data with bigger.fluctuation. The numer.cal r.sults of r.al dr.ft data fr.m a cer.ain typ. FOG ver.fy the effectiveness of the p.op.sed gr.y Mar.ov chain model p.wer.ully. The Mar.ov chain is also investigated to p.ovide a comp.r.son with the gr.y Mar.ov chain model. It is shown that the hybr.d gr.y Mar.ov chain p.ediction model has higher.modeling p.ecision than Mar.ov chain itself, which p.ove this p.op.sed method is ver. ap.licable and effective.
