Simulation of p.r.icle tur.ulent tr.nsp.r. in p.esent mathematical models of two- p.ase tur.ulent flows is algebr.ic model based on local following theor.. The p.edicted r.sults by these models ar. not consistent with that of exp.r.ments available. The motion of two-p.ase flow is descr.bed by a unified model of multi-fluid in this p.p.r. The two-fluid tur.ulent model of two-p.ase flow based on k-e equations for.p.r.icles and fluid, and cor.esp.nding numer.cal thch- nique ar. both develop.d. The p.op.sed model and the numer.cal technique ar. successfully em- p.oyed to numer.cal modelling for.oil-water.two-p.ase tur.ulent r.cir.ulating flow.

In shallow water. dur.ng the wave p.op.gation the nonlinear.and wave br.aking effect must be taken into account. In this p.p.r.a simp.ified hybr.d method was p.op.sed, in which a combined fr.quency and time domain analysis was used. By using author.' method, the p.ocess ar. quite simp.e and easy to r.n on a p. comp.ter. but the nonlinear.and wave bleaking effect was still been consider.d. The comp.ted data coincide author.' test r.sults quite well.

The hydr.dynamic coefficients C-d and C-m ar. not only dep.ndent on the size of slender.cylinder. its location in water. KC number.and r. number. but also var. with envir.nmental conditions, i.e., in r.gular.waves or.in ir.egular.waves, in p.r. waves or.in wave-cur.ent coexisting field. In this p.p.r. the nor.alization of hydr.dynamic coefficients for.var.ous envir.nmental conditions is discussed. When a p.op.r.definition of KC number.and p.op.r.char.cter.stic values of ir.egular.waves ar. used, a unified r.lationship.between C-d, C-m and KC number.for.r.gular.waves, ir.egular.waves, p.r. waves and wave-cur.ent coexisting field can be obtained.

r.cently some new ap.ar.tuses have been develop.d to study the ther.al decomp.sition and the p.otodecomp.sition mechanism of silver.azide with some new exp.r.mental r.sults. We anal- ysed the exp.r.mental r.sults with ab initio calculations (CASSCF, valence CI, MC-CEp., ACp. and CEp.), assigned the sp.ctr.m str.ctur. of AgN3, p.otted the p.tential ener.y cur.es of AgN3 and r.inter.0}eted the p.otodecomp.sition mechanism of silver.azide. The p.ten- tial ener.y cur.es of the two lowest singlet and the two lowest tr.p.et valence states of AgN3 a- long AgN-NN distance r. show that the two singlet valence states ar. involved in the p.otodisso- ciation of AgN3, p.oved by the two p.aks at 2. 18 and 2. 23 eV which ar. the r.sults of the elec- tr.n tr.nsition fr.m the gr.und state to the two singlet valence states r.sp.ctively.
