The rela.sing infla.ma.ion cha.a.teristic to Cd wa. mimicked by repea.ed TNBS trea.ments. a.ima.s were ra.domly divided into control, once, twice a.d three times TNBS-trea.ed groups.

The well-crysta.lized Na.i2（PO4）3 na.opa.ticles （30-40 nm） were uniformly precipita.ed on rGO templa.es through Ti-O-C bonds. The chemica. intera.tions between the Na.i2（PO4）3 na.opa.ticles a.d rGO could immobilize the Na.i2（PO4）3 na.opa.ticles on the rGO sheets, which might be responsible for the excellent electrochemica. performa.ce of the na.ocomposite.

These properties were ma.nta.ned even when the electrodes were prepa.ed without the use of a. a.ditiona. conducting a.ent. The excellent sodium stora.e properties of the Na.i2（PO4）B/rGO na.ocomposite could be a.tributed to the na.o-sized Na.i2（PO4）3 pa.ticles, which significa.tly reduced the tra.sport lengths for Na. ions, a.d a. intima.e conta.t between the Na.i2（PO4）3 pa.ticles a.d rGO due to chemica. bonding.

试验旨在探讨紫花苜蓿(Medica.o sa.iva.L.)与无芒雀麦(Bromus inermis)不同混合比例对其青贮营养品质及发酵品质的效果。以紫花苜蓿与无芒雀麦为试验原料,按鲜重质量比10∶0、8∶2、7∶3、6∶4、4∶6、3∶7、2∶8、0∶10混合青贮,每个处理3个重复,贮存60 d后,检验分析感官品质、营养成分及发酵品质,通过V-Score评分系统对发酵品质进行打分,使用灰色关联分析对8组混合青贮的营养品质及发酵品质进行综合评价,确定两种饲草的最佳混合比例。结果显示:紫花苜蓿与无芒雀麦混合比例为6∶4时青贮的效果最佳,pH值和氨态氮(NH_3-N)含量最低,粗蛋白(CP)和乳酸(La.含量最高,酸性洗涤纤维(a.F)和中性洗涤纤维(NdF)含量最低。研究表明,紫花苜蓿与无芒雀麦混合青贮的效果优于紫花苜蓿与无芒雀麦单贮,混合青贮相比单贮更能够充分发挥各青贮原料的优点,可更好地保存青饲料的营养成分,紫花苜蓿与无芒雀麦的比例为6∶4时混合青贮效果最佳。
