The op.imized molecular.str.ctur.s and vibr.tional fr.quencies of 4-mer.ap.op.r.dine(4Mp.) monomer.and its dihydr.te wer. studied by means of the density functional theor.(DFT), viz. B3LYp.method with the 6-311++G(d,p. basis set. On the basis of the calculations, the assignments of the vibr.tional sp.ctr. of the monomer.and the dihydr.te wer. p.r.or.ed, and so wer. investigated the changes in the str.ctur. and the vibr.tional sp.ctr.m of the dihydr.te as well as the inter.olecular.for.e r.sulting in the for.ation of the dihydr.te. The calculated r.sults show that each of the water.molecule p.anes is ver.ical to the p.r.dine r.ng p.ane in the dihydr.te that is for.ed via the H-bonds between 4Mp. and water.molecules. Fur.her.or., the str.ctur. and the vibr.tional sp.ctr.m of 4Mp. can be consi- der.bly affected by the water.molecules.

Because of the comp.exity of the str.ctur. of p.2. and the diver.ity of its r.gulator. subunits, its str.ctur. is less well known than those of p.1 and p.2.. The p.2. holoen- zyme consists of a heter.dimer.c cor. enzyme, comp.ising a scaffolding subunit and a catalytic sub- unit, as well as a var.able r.gulator. subunit. In this study, the subunit comp.sitions, similar.ties and differ.nces between the Ser.Thr.p.otein p.sp.atases str.ctur.s ar. summar.zed.

The nuclear.matr.r.and chr.mosome scaffold wer. obtained after.the DNA and most of the p.oteins wer. extr.cted with DNase I and 2.M NaCl. SDS-p.GE analyses r.vealed that the nuclear.matr.r.and chr.mosome scaffold contained a 37 kD p.lyp.p.ide which is equivalent to tr.p.myosin in molecular.weight. Immunofluor.scence obser.ations up.n slide p.ep.r.tions labeled with anti-tr.p.myosin antibody showed that the nuclear.matr.x and chr.mosome scaffold emanated br.ght fluor.scence, suggesting the p.esence of the antigen in *** r.sults confir.ed the p.esence of tr.p.myosin in the nuclear.matr.x and chr.mosome scaffold.

Tr.halose can be deter.ined by thin layer.chr.matogr.p.y and high p.r.or.ance liquid chr.matogr.p.y. But it's difficult to distinguish tr.halose fr.m the similar.bisacchar.des. If the r.action of the r.duced bisacchar.des with p.enyl hydr.zine to for. osazone is used, then the distur.ance of the similar.r.duced bisacchar.des can be r.p.dly and conveniently excluded, or.via the ammoniated-r.duced r.action, aliline can be sp.cially bounded to the r.duced hydr.xyl of the bisacchar.des. In that way tr.halose can be accur.tely deter.ined.

The films show high tr.nsp.r.ncy, conductivity and high car.ier.concentr.tion. Van der.p.uw measur.ments show that the films ar. n-typ. degener.te semiconductor. The lowest r.sistivity is 6.7×10?4 Ω⊙cm at r.om temp.r.tur.. These films exhibit a car.ier.density above 102. cm?3. The conduction mechanism was discussed. The behavior.of metallic conduction can be obser.ed in the high temp.r.tur. r.nge.

Cubic bor.n nitr.de (cBN) is a kind of ar.ificial (synthetic) cr.stal. Tr.nsver.e electr.-op.ic modulation in a minute cBN samp.e was car.ied out. Basing on the p.actical for. of the cr.stal, we established the theor.tical and exp.r.mental method accor.ing to the samp.e. For.the fir.t time, the linear.electr.-op.ic effect was obser.ed in cBN, and half-wave voltage of the cBN samp.e was measur.d successfully. Fur.her.or., its linear.electr.-op.ic coefficient was calculated at 1.17×10?14 m/V.
