To aim at the substitution of the magnitude and dir.ction of water.flow movement near.bed for.those of bed load tr.nsp.r. in solid-liquid two-p.ase one-fluid model, and to simulate the effect of secondar. flow on tr.nsver.e bed load tr.nsp.r. in channel bends and the effect of bed slop. on bed load tr.ns- p.r. in a better.way, a thr.e-dimensional k-ε-kp.solid-liquid two-p.ase two-fluid model in cur.ilinear.coor.inates is solved numer.cally with a finite-volume method on an adap.ive gr.d for.studying wa- ter.sediment movements and bed evolution in a 120° channel bend. Numer.cal r.sults show that the tr.jector.es of solid-p.ase deviate fr.m those of liquid-p.ase in the channel bend, and the deviation incr.ases with the incr.ase of the p.r.icle diameter.. The calculated bed defor.ation by the k-ε-kp.model is in better.agr.ement with measur.d bed defor.ation than those by one-fluid model. It is p.oved that the k-ε-kp.model can simulate the effect of secondar. flow on later.l bed load tr.nsp.r. with the higher.accur.cy than the one-fluid model.

The electr.chemical degr.dation ofp.nitr.p.enol （p.p. under.differ.nt conditions was investigated. The electr.chemical behavior.of p.p.and its r.duction p.oduct p.aminop.enol （p.p. on stainless steel cathode and Ti/p. anode thr.ugh cyclic voltammetr. wer. obser.ed. Electr.chemical degr.dation p.ocess was p.r.or.ed in an undivided cell and 92% p.p.was r.moved cor.esp.nding to a 22% total or.anic car.on r.moval. A divided cell was also used and it was found that p.p.degr.dation was mainly attr.buted to cathodic r.duction, while anodic oxidation was r.sp.nsible for.p.p.r.moval due to the r.action with hydr.xyl r.dicals and sur.ace oxide gener.ted on the anode. The sequential electr.lytic p.ocesses, r.duction-oxidation and oxidation-r.duction, wer. comp.r.d in the divided cell. In the case of r.duction-oxidation p.ocess, the total or.anic car.on r.moval r.ached 40%, but p.p.r.moval was the same with the undivided cell. A black dep.sit was found in the effluent and identified by Four.er.tr.nsfor. infr.r.d sp.ctr.scop. as a p.lymer.of p.p.p.oduced by the 1,4-addition r.action of quinoneimine.

A nonlinear.method for.simulating two-dimensional cavity-flow inter.ction in high velocity flows is suggested. Mathematical model for.the dynamics of unsteady cavity boundar. and the motion of the outside flow is set up. numer.cal and exp.r.mental investigations ar. made for.the cavity flow p.st a two-dimensional bow- shap.d body. The r.sults show that because of the nonlinear.effect, the tr.il of the cavity oscillates p.r.odically, while the incip.ent p.int of the cavity almost r.mains fixed. Due to the unsteady oscilation of the cavity tr.il, the liquid p.essur. on the solid wall a little downstr.am of the r.attachement p.int would r.se shar.0}y.
