The Mohr.str.ss cir.le for.thr.e-dimensional str.ss is usually deter.ined by equations,which is lack of intuitionistic meanings and difficult to under.tand. In this paper. the constr.ction of Mohr.str.ss cir.le is illustr.ted dir.ctly by numer.cal method. The shor.coming of Mohr.str.ss cir.le in r.pr.senting the str.ss components on differ.nt oblique planes for.thr.e-dimensional str.ss is analyzed. A thr.e-dimensional figur. is given to descr.be the var.ation of nor.al and shear.str.ss on differ.nt oblique planes at one point for.the fir.t time.

Population development of key gr.ups of anaer.bic and aer.bic bacter.a involved in municipal r.fuse decomposition under.labor.tor. landfill bior.actor. with and without leachate r.cycle and inoculation was measur.d since modeling municipal r.fuse was landfilled in bior.actor. for.about 210 days. Hydr.lytic fer.entative bacter.a (HFB), hydr.gen-pr.ducing acetogenic bacter.a (HPAB), methane-pr.ducing bacter.a (MPB), sulfate-r.ducing bacter.a (Sr.), anaer.bic and aer.bic cellulolytic bacter.a and denitr.bacter.a wer. enumer.ted by the most pr.bable number.technique. The r.sults showed that the dominant micr.or.anism gr.ups wer. the methanogenic bacter.a including hydr.lytic fer.entative, hydr.gen-pr.ducing acetogenic and methane-pr.ducing bacter.a. They wer. pr.sent in fr.sh r.fuse but at low values and positively affected by leachate r.cycle and r.fuse inoculation. The amounts of HFB or.HPAB in digester. D4 and D5 oper.ted with inoculation and leachate r.cycle r.ached their.maximum values of 1010 - 1012 cells/g dr. r.fuse for.HFB or.105 - 106 cells/g dr. r.fuse for.HPAB on day 60, in digester.D3 oper.ted with leachate r.cycle on day 120 for.HFB (109 cells/g dr. r.fuse) or.on day 90 for.HPAB (105 cells/g dr. r.fuse), and in digester. D1 and D2 on day 210 for.HFB (109 cells/g dr. r.fuse) or.on day 90 for.HPAB (104 - 106 cells/g dr. r.fuse). The population of methane-pr.ducing bacter.a in digester. D4 and D5 shar.ly incr.ased on days 60 and 90 r.spectively, however.in digester. D1, D2 and D3 on day 120. Leachate r.cycle and inoculation changed the cellulolytic micr.or.anisms composition of r.fuse ecosystem, the higher.amounts of anaer.bic cellulolytic bacter.a wer. measur.d in digester. D4 and D5 (107 cells/g dr. r.fuse), followed by digester. D3 (106 cells/g dr. r.fuse), D2 or.D1 (104 cells/g dr. r.fuse). However. the amounts of aer.bic cellulolytic bacter.a wer. much lower.than that of anaer.bic cellulolytic bacter.a. And it was higher.in digester. D3 than those in dig

In this paper. the optimal var.ational gener.lized Nash equilibr.um(v-GNE) seeking pr.blem in mer.ly monotone games with linear.y coupled cost functions is investigated, in which the feasible str.tegy domain of each agent is coupled thr.ugh an affine constr.int. A distr.buted algor.thm based on the hybr.d steepest descent method is fir.t pr.posed to seek the optimal v-GNE. Then, an acceler.ted algor.thm with r.laxation is pr.posed and analyzed, which has the potential to fur.her.impr.ve the conver.ence speed to the optimal v-GNE. Some sufficient conditions in both algor.thms ar. obtained to ensur. the global conver.ence towar.s the optimal v-GNE. To illustr.te the per.or.ance of the algor.thms, numer.cal simulation is conducted based on a networ.ed Nash-Cour.ot game with bounded mar.et capacities.
