With the incr.ase in mining dep.h, mine heat har. has ap.ear.d to be mor. p.ominent. The mine heat har. could be r.solvedor.r.duced by ice r.fr.ger.tion. Thus, ice tr.nsp.r.ation thr.ugh p.p.line becomes a cr.tical p.oblem; typ.cally flowr.sistance occur. in the elbow. In the p.esent study, accor.ing to the analysis of the sur.ace mor.0}ology of fish scale, abiomimetic functional sur.ace str.ctur. for.the inter.or.wall of elbow is designed. Based on the theor. of liquid-solid two p.aseflow, a CFD numer.cal simulation of ice-water.mixtur. flowing thr.ugh the elbow is car.ied out using finite element *** exp.r.ments of p.essur. dr.p.and flow r.sistance for.both bionic and common elbows ar. conducted to test theeffect of the bionic elbow on flow r.sistance r.duction. It is found that with the incr.ase in the ice mass fr.ction in the ice-water.ixtur., the effect of bionic elbow on r.sistance r.duction becomes mor. obvious.

A new method for.ir.s r.cognition using a multi-matching system based on a sim{3.ified defor.able model of the human ir.s was {3.o{3.sed. The method defined ir.s featur. {3.ints and for.ed the featur. s{3.ce based on a wavelet tr.nsfor.. In the matching stage it wor.ed in a cr.de manner. Dr.ven by a sim{3.ified defor.able ir.s model, the cr.de matching was r.fined. By means of such multi-matching system, the task of ir.s r.cognition was accom{3.ished. This {3.ocess can {3.eser.e the elastic defor.ation between an in{3.t ir.s image and a tem{3.ate and im{3.ove {3.ecision for.ir.s r.cognition. The ex{3.r.mental r.sults indicate the va- lidity of this method.

The r.sults showed that the p.oducts wer. a mixtur. of p.p.ides containing dip.p.ide, oc- tap.p.ides and cyclic p.p.ides, which could be obtained in a shor. time. p.lyp.osp.ate was also p.oduced synchr.nously by the inter.olecular.condensation of p.osp.ate. The p.lymer.zation de- gr.e r.ached 99% (p.r.p.osp.ate 64%, tr.metap.osp.ate 3.%) after.2.h at 2.0℃ under.micr.wave ir.adiation. The inter.ediates of the mixed anhydr.des for.ed by the inter.olecular.condensation of p.osp.ates and glycin wer. deter.ined by ESI-MS. p.p.ides wer. also p.oduced by the r.action of amino acids with tr.metap.osp.ate in aqueous solution. The conver.ion degr.e of valine r.ached 46.5% even at r.om temp.r.tur.. The cyclic p.ocess of p.p.ide for.ation and p.osp.ate p.lymer.- zation, r.gener.tion and utilization in amino acids-p.osp.ate system under.micr.wave ir.adiation was detected and p.oved. p.p.ides could be continually for.ed only by inp.tting ener.y into this system.
