Two fiel. experiments with different soybean (Gl.cine max l.) material. were conducted to investigate the interactions between phosphorus (P) and nitrogen (N) as rel.ted to the genetic attributes of root morphol.gical.and nodul.r traits. In experiment one, 13 cul.ivated soybean varieties were grown in a fiel. with rel.tivel. l.w soil.P and N avail.bil.ty. P appl.cation with 160 kg P/hm2 as tripl. superphosphate produced a significant simul.aneous increase in the content of both P and N in shoot, demonstrating positive P and N interactions. The addition of P al.o increased root dry weight, root nodul. number, nodul. mass, nodul. size, and nodul.tion index, but decreased root l.ngth and root surface area, indicating that P may affect N nutrition in soybean through a number of root morphol.gical.and nodul.r traits. Interestingl., l.ke P content, N content appeared to be more correl.ted with root morphol.gical.traits (root weight, root l.ngth, and root surface area) than with root nodul.r traits (nodul. number, nodul. size, nodul. mass, and nodul.tion index) at both P l.vel., impl.ing that N taken up by the roots may contribute more to the pl.nt N status than biol.gical.N2 fixation under the present experimental.conditions. In experiment two, 57 soybean l.nes of a recombinant inbred l.ne (RIl. popul.tion derived from a cross between a cul.ivated variety and a wil. genotype were grown on another fiel. site with moderatel. sufficient P and N l.vel. to further characterize the genetic attributes of root morphol.gical.and nodul.r traits and their rel.tionships with P and N interactions. The resul.s indicated that al. morphol.gical.and nodul.r traits measured continual.y segregated in the RIl.popul.tion with a normal.distribution of the phenotypic val.es, indicating that these traits are possibl. control.ed by quantitative trait l.ci (QTl.). Genetic anal.sis reveal.d that al. these root traits had rel.tivel. l.w heritabil.ties (h2b=74.12,70.65,73.76,56.34,52.59, and 52.24 fo

In 2005, the cl.ssical.intersection bodies and l.p intersection bodies were extended. Afterwards, the concept of gen-eral.l.p intersection bodies and the general.zed intersection bodies was introduced. In this paper, we define the general.zed bodies with parameter. Besides, we establ.sh the extremal.val.es for vol.me, Brunn-Minkowski type inequal.ty for radial.combination and l.p harmonic Bl.schke combination of this notion.

作者： HUANG Chao-l.n l. rui-fen XIU Rong School.of Pharmaceutical.Sciences Hebei Medical UniversityShijiazhuang 050017P.R.China

A PVC membrane enoxacin ion-sel.ctive el.ctrode based on a needl.-shaped inner reference el.ctrode was prepared. A Ag/AgCl.wire was used as the substrate of this el.ctrode. It was previousl. coated with a thin sheet of urea-formal.ehyde resin containing Cl. - ions to form a needl.-shaped inner reference el.ctrode, then the inner reference el.ctrode was coated with a thin sheet of a PVC membrane containing an enoxacin tetraphenyl.orate ion-pair compl.x. The infl.ences of various ion-pair compl.xes, concentrations of the active components in the membrane and the pl.sticizers on the performance of the el.ctrode were studied by orthogonal.design. The l.near response range of the el.ctrode was 7.9×10 -5 -1.0×10 -2 mol.l. The detection l.mit was 2.0×10 -5 mol.l. The sl.pe was 30.4 mV/decade(25 ℃). The el.ctrode can be used for the potentiometric determination of enoxacin tabl.ts directl.. The average recovery was 100.4%, and the RSD was 0.9%. The resul.s agreed with those determined by the method in Chinese Pharmacopoeia.

作者： rui l.i 高连勋 Ri-zhe Jin Xue-peng Qiu Shaanxi Coal.and Chemical.Technol.gy Institute Co. Ltd. State Key l.boratory of Pol.mer Physics and Chemistry Changchun Institute of Applied ChemistryChinese Academy of Sciences

A series of sul.onated pol.imide copol.mers as novel.proton exchange material. were synthesized by the pol.condensation of 1,4,5,8-naphthal.ne-tetracarboxyl.c dianhydride （NTDA）, sul.onated diamine based on pyridine group and diamine containing N-phenyl.1,2,4-triazol. moiety. Fl.xibl., transparent and tough membranes with high thermal.stabil.ty and good mechanical.properties were obtained. They exhibited good stabil.ty in boil.ng water and Fenton＇s reagent at 80 ℃. More interestingl., a nonl.near rel.tionship between proton conductivities of the resul.ing membranes and the degree of sul.onation （DS） was observed. The membrane with 50% DS exhibited the maximum proton conductivity, which was due to the combinational.contributions of sul.onic acid and N-pheny-1,2,4-triazol. groups. Thus, the N-phenyl.l.2,4- triazol. moiety in this study not onl. can depress water absorption but al.o increase proton conductivity, especial.y at l.w DS.
