采用直径为1.2 mm的er2594-超级双相不锈钢焊丝进行了多层单道墙体电弧增材试验,对增材件分别进行1050、1150和1250℃的固溶处理,并在固溶处理后对各试样进行了往复式摩擦磨损试验.试验结果表明:随着固溶温度的升高,双相比中的铁素体含量增加,其显微硬度也相应提高.此外,固溶处理可降低增材件的内应力,最终基于较高硬度和较低内应力的协同作用,在1250℃时获得耐磨性能较优的试样,有效地提升了热处理后增材件试样的摩擦磨损性能.

An integratio.-centric appro.ch is pro.o.ed to.handle inadequate info.matio. in the system readiness level （SRL） assessment using the evidential reaso.ing （er） algo.ithm. Current SRL assessment appro.ches canno. be applied to.handle inadequate info.matio. as the input. The er-based appro.ch is pro.o.ed to.synthesize inadequate input info.matio. and an integratio.-centric perspective is applied to.reduce the co.putatio.al co.plexity. Two.case studies are perfo.med to.validate the efficiency o. the pro.o.ed appro.ch. And these studies are also.perfo.med to.study ho. the inadequate info.matio. will affect the assessment result. And the differences caused by the system＇s structure. The impo.tance o. the system＇s structure in the SRL assessment is demo.strated and the co.tributio.s made in this study are summarized as co.clusio.s.

o.jective To.evaluate the impacts o. repro.uctive tract infectio.s （RTIs） interventio. o. RTIs-related kno.ledge, attitudes, practices and prevalence o. married wo.en at repro.uctive age. Metho.s Fo.r sub-districts fro.

RTIs interventio. was implemented in interventio. gro.p, while ro.tine family planning pro.ram was co.ducted in co.tro. gro.p. Results Co.pared with co.tro. gro.p, interventio. gro.p have impro.ed the fo.lo.ing targets： the increment o. RTI kno.ledge sco.e was higher than that in co.tro. gro.p （o.=9. 22, 95%CI： 7.01 - 2.14）; the increment sco.e o. individual health behavio.s （6. 31） was higher than that in co.tro. gro.p （4.50）（o.=1.60, 95%CI： 1.21 -2.10）; the increase o. co.do. use frequency in interventio. gro.p was higher than that in co.tro. gro.p （4.12% vs 0.69%）（o.=1.84, 95%CI： 1.31-2.57）; the decreased RTIs rate was higher than that in co.tro. gro.p （7.45% vs 0.96%）（o.=0.68, 95%CI： 0.49-0.95）. Co.clusio. It is an effective way to.co.duct co.munity-based interventio. to.increase wo.en＇s RTIs kno.ledge, impro.e RTIs-related attitudes, pro.o.e go.d individual health behavio.s, so.as to.decrease RTIs prevalence.
