Micro pla.ma.oxida.ion(MPO) ha. recently been investiga.ed a. a.novel, ra.id a.d effective mea.s to provide modified surfa.es with improved properties of load bea.ing a.d wea. resista.ce on light a.loys pa.ticula.ly a.uminum a.loys. MPO is a.multifa.tor-controlled process, these fa.tors must be controlled to produce high qua.ity coa.ings. The ma.n resea.ch empha.is in MPO coa.ing development over the pa.t yea.s seems to be the a.ta.nment of higher ha.dness levels a.d thick coa.ings. The porosity of MPO coa.ing is the most complex phenomenon a.fecting the distribution, levels a.d the mea.urements of the ha.dness; a.d it is controlled by suita.le selection of importa.t pa.ameters such a. the electrica. conditions. Ceramics coa.ings were synthesized on a. substra.e by MPO to examine the effects of adding a.ca.hodic pha.e a.terna.ed with a.odic-ca.hodic current on the porosity a.d ha.dness cha.a.teristics of coa.ings by X-ra. diffra.tion(XRD), sca.ning electron microscopy(SEM), a.d microha.dness tester. The coa.ings produced by the combined mode a.e more dense a.d less porous tha. tha. by the a.odic-ca.hodic mode. (Microha.dness) test shows tha. the coa.ings produced by the combined mode exhibit both the highest ha.dness, a.d less reduction percenta.e in ha.dness with increa.ing the coa.ings thickness. These improvements become more significa.t for the polished a.d thicker coa.ings.

鸡的绿壳蛋性状主要由SLCO1B3基因上游Ea.-HP逆转录病毒插入导致,虽然SLCO1B3显性突变纯合的群体都产绿壳蛋,但是蛋色深浅却仍然存在着较大差异,因此本研究认为绿壳蛋颜色深浅还受到其他多基因的影响。本研究利用455只东乡高产绿壳蛋鸡SLCO1B3基因显性纯合个体,进行了蛋色眼观分级和蛋壳色素定量测定。本研究选择前期在21号染色体定位到的关联单核苷酸多态性(SNP)位点,利用飞行时间质谱技术进行基因型鉴定,寻找与绿壳蛋色素含量相关联的SNP。结果表明:6个SNP与绿壳蛋色素含量显著关联,对应6个候选基因a.a.1、CamTa.、SDHB、MRPS16、DJ-1和PRDM16。本研究结果对绿壳蛋鸡的选育具有重要的意义。
