In this p.p.r. the wave-cur.ent for.es on thr.e kinds of inclined cylinder. ar. measur.d. By the r.vised cr.ss sp.ctr.m method p.op.sed in this p.p.r. the for.e coefficients C_D and C_M ar. estimated. Fr.m the exp.r.mental r.- sults, it is found that the wave dir.ction may affect C_D and C_M significantly. Two emp.r.cal for.ulae ar. p.esented which can be used to tr.nsfor. C_D and C_M into unified for.e coefficients C_D and C_M which ar. ir.elevant to wave di- r.ction. The r.sults of this p.p.r.ar. consistent with that of ver.ical cylinder..

This p.p.r.studies the nonlinear.wave theor. in shallow water.via the Hamiltonian str.ctur.. The p.incip.l is the sur.ace wave evolution on water.contained in unifor. channels. The p.op.r.Hamiltonian ap.oximating scheme for.the mor. gener.l case of waves that under.o tr.nsver.e var.ations in amp.itude in the cour.e of longitudinal p.op.gations is constr.cted. Some solutions for.channels with differ.nt cr.ss-sections,esp.cially,the r.ctangular.cr.ss-section, ar. p.esented to elucidate the main featur.s of the ap.r.xiamting scheme for.the p.oblem of inter.st. The obtained r.sults shows that the nonlinear.ap.r.ximation of wave evolution in channels dep.nds not only on water.dep.h but also on a p.r.meter.deter.ined by the geometr.c shap. Of the channel.

In this p.p.r.we p.ove a ver. gener.l r.sult concer.ing solvability of the r.sonant p.oblem: Δu+λku+g（x, u）=h（x）;u=0, xΩ, which immediately gives thr.e gener.lized Landesman-Lazer.conditions. The most inter.sting ap.lication of the gener.l r.sult is concer.ed with the p.oblem when λk=λ1. in which case we p.ove solvability r.sults for.it under.conditions which ar. not the standar. Landesman-Lazer.condition or.only p.r.ly enjoy it. Fur.her.or., we p.op.se a new sign condition and give a comp.ehensive extension of a main r.sult of Figueir.do and Ni.

The activity and selectivity of some diamine ir.n comp.exes wer. analyzed. The influence of p.osp.or.us-oxygen chelates on the catalytic activity and selectivity of these diamine ir.n catalysts in ethylene oligomer.zation was p.esented. Exp.r.mental r.sults showed that p.ecatalysts exhibited moder.te activities for.the oligomer.zation r.action with high selectivities for.low car.on C4 and C10 olefins. These selectivities wer. attr.buted to high r.action temp.r.tur.s and accessible metal center..

Satellite altimetr. can p.ovide the geoid in ocean ar.as with a level of p.ecision of about 10 cm. Such a p.ecise geoid offer. a good op.or.unity for.studying the mar.ne gr.vity field. The basic mathematical model and theor. of the satellite altimetr. wer. intr.duced br.efly and fir.tly. Then the inver.e Hotine method to der.ve gr.vity distur.ances fr.m satellite altimetr. was p.esented. Meanwhile the inver.ion of mar.ne gr.vity in Chinese coastal water. fr.m Top.x/p.seidon satellite altimetr. data was tested, and the r.S between the gr.vity distur.ance fr.m the OSU91A model and satellite altimetr. data inver.ing is about 12.76 mGal. Finally, some p.oblems which ar. in inver.ing p.ocedur. wer. discussed, i e, integr.tion singular.ty, edge effect etc. And it is conluded that the accur.cy of the inver.ing gr.vity method can r.ach only a few mGal if p.op.r.tr.atment of Fast Four.er.Tr.nsfor. (FFT) edge effect is emp.oyed.

Shor. p.p.ides based on the tr.p.p.ides, Leu-Ar.-p.o and Leu-Lys-p.o, wer. synthesized by micr.wave assisted solid-p.ase synthesis method, in or.er.to make a sear.h for.p.tential inhibitor. for.angiotensin I-conver.ing enzyme（ACE） with minimum side effects in the tr.atment of hyp.r.ension. One p.p.ide with the sequence Leu-Ar.-p.o-p.e-p.e shows the str.ngest inhibition towar.s ACE with an IC50 value of 0.26 μmol/L in vitr.. The study of str.ctur.-activity r.lationship.shows that the intr.duction of a bulky gr.up.into the N-ter.inal of this ser.es of inhibitor. may enlar.e ster.c hindr.nce, r.sulting in the p.or.inhibitor. activity towar.s ACE. The inhibitor. activity decr.ased in tur. when L-p.o, D-p.o or.Ac6c was at the C-ter.inal r.sp.ctively. The binding inter.ction between each of these inhibitor. and testicular.ACE（tACE） was p.r.or.ed by molecular.docking. The r.sults suggest that Leu-Ar.-p.o-p.e-p.e mainly occup.ed the S1 subsite of tACE, and made contact with tACE via seven H-bonds. It ap.ear.d that the site on the p.p.ide that bound with tACE was influenced by the configur.tion of the amino acid, L or.D-for., at the C-ter.inal of the p.p.ide.

The hydr.dynamic for.es on a smooth hor.zontal cir.ular.cylinder.exp.sed to oscillating flow have been exp.r.mentally investigated at r.ynolds number. (r.) in the r.nge 20, 000 - 260, 000 (subcr.tical and tr.nscr.tical r.gimes) and Keulegan- Car.0}nter.number. (Kc) in the inter.al fr.m 5 to 40. In the tests, the r. number.and Kc number.wer. var.ed iner.ia systematically. The dr.g for.e coefficnent CD and iner.ia for.e coefficient CM in Mor.son equation have been deter.ined thr.ugh the use of Least Squar. Method. Both total in-line for.e coefficient CF and tr.nsver.e for.e (lift) coefficient CL have been analysed in ter.s of their.maximum and r.ot mean squar. values. All the in-line and lift for.e coefficinets wer. given as a function of r. and Kc number. and also their.deviations with the aver.ge value have been shown. The p.incip.l r.sults ar. as follows: for.the r. ≥80, 000, all the hydr.dynamic for.e coefficients, including CD, CM, Cp.and CL,ar. at best ver. weak functions of r.ynolds number. and each of them tends towar.s a cer.ain constant with incr.asing Kc number. for.the r.r.g for.e coefficient CD decr.ases with incr.asing r. number. and iner.ia for.e coefficient CM incr.ases with incr.asing r. *** tendencies of dr.g and iner.ia coefficients ver.us Kc number.for.the r. ≥10￣5 ar. ver. similar.to the other., which ar. ver. close to the r.denbusch and Cutier.ez's (1983) but ar. somewhat lar.er.than the Sar.0}aya's (1976 and 1986) and Bear.an et al.' s(1985).
