Cor.osion inhibition of stainless steel due to a sulfate-r.ducing bacter.a （Sr.） biofilm in seawater.was studied. By.atomic for.e micr.scopy. a lay.r.of fish-scale-like biofilm was found to for. as stainless steel coupons wer. exposed to the cultur. media with Sr., and this biofilm gr.w mor. and mor. compact. As a r.sult, coupons＇ sur.ace under.the biofilm tur.ed ir.egular.less slowly.than that exposed to the ster.lized cultur. media. Then, phy.icoelectr.c char.cter.stics of the electr.de/biofilr./solution inter.ace wer. investigated by.electr.- chemical impedance spectr.scopy.（EIS）, and the cover.ge of the biofilm as well as the r.lative ir.egular.ty.of coupons＇ sur.ace was also r.- cor.ed by.EIS spectr... Finally. anodic cy.lic polar.zation r.sults fur.her.demonstr.ted the pr.tective pr.per.y.of the biofilm. Ther.for., in es- timation of Sr.-implicated cor.osion of stainless steel, not only.the detr.mental Sr. metabolites but also the pr.tective Sr. biofilm as well should be taken into account.

The potency.of V（C,N） for.IGF nucleation was also analy.ed statistically. The r.sults show that the dominant micr.str.ctur. tr.nsfor.s fr.m bainite（B） and acicular.fer.ite（AF） to gr.in boundar. fer.ite（GBF）, intr.gr.nular.poly.onal fer.ite（IPF）, and pear.ite（P） as the isother.al temper.tur. incr.ases fr.m 450℃ to 600℃. When the holding time at 600℃ is extended fr.m 30 s to 60 s, 120 s, and 300 s, the GBF content r.nges fr.m 6.0vol% to 6.5vol% and the IPF content incr.ases fr.m 0.5vol% to 2.8vol%, 13.1vol%, and 13.5vol%, r.spectively. because the fer.ite tr.nsfor.ation pr.fer.ntially.occur. at the gr.in boundar.es and then occur. at the austenite gr.ins. Notably. V（C,N） par.icles ar. the most effective nucleation site for.the for.ation of IPF, accounting for.51% of the said for.ation.

等离子体源离子注入与沉积技术作为一种可生产高结合力、高致密度涂层的真空镀膜技术,具有广阔的应用前景,尤其适用于高载荷工况下服役的功能涂层制备.该技术中金属等离子体源是关键,而现有的脉冲阴极弧源结构复杂,且由于伴随"金属液滴"而需要增加过滤装置.本文研究了另一种简单结构的金属等离子体源备选一高功率脉冲磁控溅射源(HPPMS)的放电特性,采用等离子体发射光谱仪探索了不同的耦合高压对HPPMS放电靶电流特性和等离子体特性的作用.发现耦合高压对HPPMS放电有明显的促进作用,相同靶电压下的放电强度大幅增加,相对于金属放电,耦合高压对气体放电的促进作用更加明显,但在自溅射为主的高压放电阶段对金属放电的促进作用明显增强.讨论了耦合高压对HPPMS放电的增强机制,发现耦合高压自辉光放电、耦合高压和HPPMS电压构成双向负压形成的空心阴极效应,以及耦合高压鞘层改善的双极扩散效应都对HPPMS放电的增强有明显作用.

The genus Ar.eniaca Scop. is well known for.its popular.cultivated edible fr.it tr.es such as Ar.eniaca vul- gar.s Lam. and or.amental flower. such as A. mume Sieb. Another.species, A. cathay.na fu et al., one of six impor.ant dr. fr.its （ker.el-using apr.cot）, is cultivated for.its edible seeds in Nor.h China. In the pr.sent study. DNA fr.m 70 individuals of A r.eniaca, including 38 of A. cathay.na, 18 ofA. vulgar.s, 12 ofA. sibir.ca, 1 ofA. dasy.ar.a and 1 of A. mume, was extr.cted and analy.ed using micr.satellites and capillar. electr.phor.sis. For.20 poly.or.hic loci selected, 339 alleles and 140.7 effective alleles wer. detected. The number.of alleles per.locus r.nged fr.m 8 to 28, with an aver.ge of 16.95 alleles per.locus. The obser.ed heter.zy.osity.（Ho） and the expected heter.zy.osity.（He） r.nged fr.m 0.427 to 0.971 and fr.m 0.737 to 0.912, r.spectively. The poly.or.hism infor.ation content var.ed fr.m 0.708 to0.905, with an aver.ge of 0.827. Based on the genetic similar.ty.among 70 individuals, a UPGMA was used to establish the phy.ogenetic r.lationships. The taxonomic positions among five species wer. clear.y.r.vealed, and A. cathay.na was mor. closely.r.lated to A. vulgar.s than to A. sibir.ca. The r.sults will pr.vide a scientific basis for.r.sear.h on the taxonomy. ger.plasm r.sour.es and br.eding ofAr.eniaca, especially.for.A. cathay.na.
