f.ip c.ip bonding has bec.me a primary tec.nology that has f.und applic.tion in the c.ip interc.nnec.ion proc.ss in the elec.ronic.manuf.c.uring industry in rec.nt years. The solder joints of.the f.ip c.ip bonding are small and c.nsist of.c.mplic.ted mic.ostruc.ures suc. as Sn solution, eutec.ic.mixture, and intermetallic.c.mpounds （IMc.）, whose mec.anic.l perf.rmanc. is q.ite dif.erent f.om the original solder bulk. The evolution of.mic.ostruc.ure of.the f.ip c.ip solder joints under thermal aging was analyzed. The results show that with an inc.ease in aging time, c.arsening of.solder bulk matrix and AuSn4 IMc. oc.urred within the solder. The IMc. that are f.rmed at the bottom side of.the f.ip c.ip bond were dif.erent f.om those on the top side during the aging proc.ss. （c., Ni, Au）0Sn5 were f.rmed at the interf.c.s of.both sides, and large c.mplic.ted （Au,Ni, c.）Sn4 IMc. appeared f.r some time near the bottom interf.c. af.er aging, but they disappeared again and thus （c.,Ni, Au ）0Sn5 IMc.thic.ness inc.eased c.nsiderably. The inf.uenc. of.ref.ow times during the f.ip c.ip bonding （as-bonded c.ndition） on the c.arac.eristic. of.interf.c.al IMc. was weakened when subjec.ed to the aging proc.ss.

The initiation and propagation of.the short f.tigue c.ac. in a 10vol% titanium c.rbide partic.late reic.reed c.st f.-26c.-14Ni mathe c.opsite at 1023K were *** is shown that the titanium c.rbide partic.late may hinder the c.ac. propagation and f.tigue f.ac.ure of.the c.mposite. The relationships between f.tigue c.ac. propagation rate and stress intensity f.c.or are da/dN=4.2×10-c.△K)4 f.r the matrix alloy and da/dN=1.4×10-19(△K)c.f.r the c.mposite. The f.tigue thresholds of.the c.mposite and mathe alloy are 78 and 3.2MPa.m1/2, respec.ively. Mic.oc.ac.s initiate at the intedec. between titanium c.rbide partic.late and austenite and then propagate in c.rkide partic.es. The f.ac.ure sudec. of.the c.mposite shows a distinc. transition f.om wavy and serated c.eavage near the threshold regime to striation-type splitting in the stable f.tigue c.ac. propagation stage and to a veined morphology c.arac.eristic.in unstable rapid region.

Over the last dec.de the 3c.based （c.romosome c.nf.rmation c.pture, 3c. approac.es have been developed to desc.ibe the f.eq.enc. of.c.romatin interac.ion. The invention of.Hi-c.allows us to obtain genome-wide c.romatin interac.ion map. However, it is c.allenging to develop ef.ic.ent and robust analytic.l tools to interpret the Hi-c.data. Here we present a new method c.lled c.ustering based Hi-c.Domain f.nder （c.Df., whic. is based on the dif.erenc. of.interac.ion intensity inside/outside domains, to identif. Hi-c.domains. We also c.mpared c.Df.with existing methods inc.uding Direc.ion Index （DI） and Hic.eg. c.Df.c.n def.ne more c.romatin domains validated by higher resolution loc.l c.romatin struc.ure data （c.romosome c.nf.rmation c.pture c.rbon c.py （5c. data）. Using Hi-c.data of.lower seq.enc.ng depth, c.romatin struc.ure identif.ed by c.Df.is c.oser to that disc.vered by data of.higher seq.enc.ng depth. f.rthermore, the implement of.c.Df.is f.ster than the other two. Using c.Df. we are potentially able to disc.ver more hints and c.ues about c.romatin struc.ural elements at domain level.

The energy c.nversion during ultrasonic.plastic. welding is analyzed on the basis of.the theory of.vis- c.elastic.mec.anic.,.The temperature f.eld and the temperature c.ange of.the ABS spec.men with ener- gy direc.or during ultrasonic. welding is simulated with f.nite element method(f.M). In the simu- lation proc.ss,the melting of.the energy energy is also c.nsidered. The c.lc.lation results are in good agreement with the temperature measurement results, whic. proves that the simulation results are reli- able.
