建立了微波消解-电感耦合等离子体质谱法(ICP-MS)同时测定铝土矿中锂、铬、铜、铁、钛、钾、钠、钙、镁、铅、锌等11种金属元素含量的方法。将铝土矿粉碎、研磨和干燥后,取0.1 g样品,加入3 mL硫酸、1 mL硝酸、2 mL氢氟酸和3 mL盐酸,按升温程序微波消解样品,加40 g·L^(-1)硼酸溶液10 mL,继续在120℃下消解10 min,使消解液变澄清。冷却后取出,180℃加热至近干,用1%(体积分数)硝酸溶液稀释,按照ICP-MS条件测定。通过用10 g·L^(-1)铝基体溶液配制混合标准溶液系列并加入内标元素Sc、Ge、Bi的方法来消除基体干扰,选择合适的待测元素同位素的方法来消除谱线重叠干扰。结果显示:11种元素的质量浓度均在一定范围内与其对应的响应值与内标元素响应值的比值呈线性关系,检出限(3s)为0.011-1.400 mg·kg^(-1)。对实际样品进行加标回收试验,测定值为0.13-72.21 mg·L^(-1),测定值的相对标准偏差(n=6)为0.69%-2.6%,回收率为94.0%-106%;此方法用于分析3种铝土矿成分分析标准物质GBW 07177、GBW 07179、GBW 07180,所得测定值均在认定值要求的范围内。

水氮耦合对燕麦光合特性的影响

西北农业学报 2013年第1期22卷 60-67页

作者：刘锁云陈磊庆胡廷会李立军刘景辉内蒙古农业大学农学院呼和浩特010019

为了解水氮耦合对燕麦旗叶光合特性的影响,揭示不同水分条件下的氮肥效应,探明适宜燕麦生长的最佳水氮条件。以燕科1号为供试材料,在防雨棚内肥水控制的条件下,研究燕麦在不同水氮条件下净光合速率(Pn)、胞间CO2摩尔分数(Ci)、气孔导度(... 详细信息

为了解水氮耦合对燕麦旗叶光合特性的影响,揭示不同水分条件下的氮肥效应,探明适宜燕麦生长的最佳水氮条件。以燕科1号为供试材料,在防雨棚内肥水控制的条件下,研究燕麦在不同水氮条件下净光合速率(Pn)、胞间CO2摩尔分数(Ci)、气孔导度(Gs)、蒸腾速率(Tr)及水分利用效率(WUE)的变化规律。结果表明,在供水欠缺的W1、W2条件下,适量的施氮可以提高水分胁迫下植物的渗透调节能力和抗旱性,达到增加Pn、Ci、Gs、Tr及WUE的目的;在供水较充足的W3条件下,施氮可明显提高燕麦各光合生理指标,而且与施氮***-2(N3)耦合,可充分发挥水氮互作优势,为最佳水氮耦合模式,但当施氮量达***-2时,各光合生理指标有下降趋势,水氮互作优势减弱。可见,水、氮水平以及水氮互作效应在一定程度上决定燕麦的光合生产能力。水、氮两因素及其互作效应对Pn、Tr、Gs、Ci、WUE的影响均达到显著或极显著水平。

为揭示影响燕麦籽粒镉(Cd)含量的关键因素,以18个燕麦品种为研究对象,分别于2020年和2021年开展连续2期大田试验,研究燕麦不同器官间Cd富集转运对籽粒Cd含量的影响,并通过聚类分析、THQ值进行低Cd积累品种筛选和安全风险评价;通过相关性分析和主成分分析评估影响籽粒Cd含量的关键器官和关键过程。结果表明:坝燕7号、201229-1-1、200919-7-1、坝莜14号、坝燕6号、白燕9号等13个品种为籽粒Cd低积累型品种,坝燕4号、燕科2号、蒙燕2号、白燕17号为籽粒Cd高积累型品种,分别占供试品种的72.22%和22.22%;燕麦籽粒Cd含量与茎中Cd富集系数及Cd从根到籽粒、茎到籽粒、叶到籽粒的转运系数呈极显著正相关;在主成分分析中,茎中Cd的富集系数及Cd从根到籽粒、茎到籽粒、叶到籽粒的转运系数对区分高、低Cd积累燕麦品种贡献较大。因此,茎是影响燕麦籽粒Cd含量差异的关键器官,Cd从根到籽粒、茎到籽粒、叶到籽粒的转运过程是造成燕麦籽粒Cd含量差异的关键转运过程。

《眼科阐微》开创了老年性眼病证治专论的先河,书中概括了老年性眼病的证候特征、阐释了病因病机、提出了治疗法则,其学术思想独具特色。在继承和发扬其学术思想的基础上,冯俊认为老年性眼病为本虚标实、脏窍同病之证,其中,脏腑为本,一身之元归脾肾;目为标,目中之元归气血;玄府-络脉为枢,标本联系剔络为要。所以,老年性眼病位在五脏和目窍,发病之本为脏腑虚损,尤责之脾、肾;发病之标为目窍,尤责之气血。本文提出归元剔络法可作为老年性眼病的治疗原则,以剔络开府、益气通窍的归元剔络方可作为治疗老年性眼病的核心方,临证中可根据其标本、虚实辨证加减。
