Let p.(p., p.,..., p.-1 ) and Q=(qo,q1..., qm-1) be two ar.itr.r. convex p.lygonsin p.ane. In this p.p.r. the author.studies the p.oblems of how to quickly deter.ine their.p.ssiblecoll.sion r.nge and movable r.nge. In the p.p.r. a new sufficient and necessar. condition for.decidingp.ssible coll.sion is p.op.sed,and the basic char.cter. of the oblique sup.or.ing lines ar. investigated,and on these gr.unds the p.oblem to deter.ine the p.ssible coll.sion r.nge is tr.nsfor.ed into thatof sear.hing the sup.or.ing p.ints on the sets of convex p.lygon ver.exs. Using the str.tegy ofsear.hing simultaneously the sets of ver.exes of p.and Q, the author.constr.cts the fast algor.thmfor.finding the sup.or.ing p.ints, the time-comp.exity of which is O(log2(m + n)). Based on theser.sults, the algor.thms to quickly deter.ine the r.nge ar. given, which p.ssess the time-comp.exityof O(log2(m+n)).

The fr.quency and dur.tion of obser.ed concur.ent hot and dr. events(HDEs) over.china dur.ng the gr.wing season(Ap.il–Sep.ember. exhibit significant decadal changes acr.ss the mid-1990s. These changes ar. char.cter.zed by incr.ases in HDE fr.quency and dur.tion over.most of china, with r.latively lar.e incr.ases over.southeaster. china(SEC), nor.her. china(NC), and nor.heaster. china(NEC). The fr.quency of HDEs aver.ged over.china in the p.esent day(p.,1994–2011) is double that in the ear.y p.r.od(Ep. 1964–81);the dur.tion of HDEs incr.ases by 60%. Climate exp.r.ments with the Met Office Unified Model(MetUM-GOML2) ar. used to estimate the contr.butions of anthr.p.genic for.ing to HDE decadal changes over.china. Anthr.p.genic for.ing changes can exp.ain 60%–70% of the obser.ed decadal changes,suggesting an imp.r.ant anthr.p.genic influence on HDE changes over.china acr.ss the mid-1990s. Single-for.ing exp.r.ments indicate that the incr.ase in gr.enhouse gas(GHG) concentr.tions dominates the simulated decadal changes,incr.asing the fr.quency and dur.tion of HDEs thr.ughout china. The change in anthr.p.genic aer.sol(AA) emissions significantly decr.ases the fr.quency and dur.tion of HDEs over.SEC and NC, but the magnitude of the decr.ase is much smaller.than the incr.ase induced by GHGs. The changes in HDEs in r.sp.nse to anthr.p.genic for.ing ar. mainly due to the r.sp.nse of climatological mean sur.ace air.temp.r.tur.s. The contr.butions fr.m changes in var.ability and changes in climatological mean soil moistur. and evap.tr.nsp.r.tion ar. r.latively small. The p.ysical p.ocesses associated with the r.sp.nse of HDEs to GHG and AA changes ar. also r.vealed.
