Recent.st.dies have suggest.d t.at.t.ere may be a link bet.een t.e use of in-feed ant.biot.cs and t.e prevalence of ant.biot.c-resist.nt.bact.ria in human infect.ons. It.is believed t.at.anaerobic digest.on is a pot.nt.met.od t. reduce t.e ant.biot.c resist.nt.bact.ria present.in wast. from concent.at.d animal feeding operat.ons. Cefazolin is a β-1act.m ant.biot.c t.at.is frequent.y used t. t.eat.t.e cows wit. mast.t.s in t.e Obihiro Universit. herd. Disposal of unt.eat.d milk cont.ining cefazolin residues promot.s t.e occurrence of cefazolin resist.nt.bact.ria in t.e vicinit. of farm, t.us t.e object.ve of t.is st.dy was t. invest.gat. t.e survival of ant.biot.c resist.nt.bact.ria in co-digest.on of dairy manure and wast. milk obt.ined from cows t.eat.d for mast.t.s wit. cefazolin under t.ermophilic condit.ons （55 ~C）. Cow manure, digest.d slurry and wast. milk （cefazolin residue concent.at.on 2.17 mg/L） were used as t.e mat.rials in order t. have t.ree digest.r cont.nt.; 100% slurry, 50% slurry ＋ 50% manure and 50% slurry ＋ 45% manure ＋ 5% wast. milk. t.e experiment.was carried out.using bat.h digest.rs （1 L） wit. act.ve volume of 800 mL at.55 ℃ for 20 days t. det.rmine t.e survival of cefazolin resist.nt.bact.ria and t. observe t.e digest.r performance by det.rmining t.e bio gas and met.ane yield using gas chromat.grapby. Dilut.on plat. met.od was used t. det.rmine t.e populat.on densit.es of t.t.l and cefazolin resist.nt.bact.ria at.0, 10t. and 20t. day of digest.on. t.t.l and cefazolin resist.nt.bact.rial count. were reduced wit. t.me by several orders unt.l 10t. day of digest.on and t.ose were almost.similar at.day 20t..

引言车轮轮缘和钢轨轨头侧面的磨耗每年都使得英国铁路耗费几百万英镑。这种磨耗在小半径曲线上尤其严重,以致往往可以看到由此产生的金属碎屑。由于不能对较长区段的钢轨进行润滑,所以轮缘润滑器的作用也有限,因此必须开展轮轨磨耗机制的研究,寻找减少磨耗的有效措施。现已在试验台上进行了轮缘与钢轨接触相对滑动和应力工况的模拟试验。本文描述滚动与滑动接触工况下轮轨的磨耗,着重研究缓和磨耗与剧烈磨
