The polarographic behavior of uranyl ion and oupferron in acetic buffer solution is studied by single-sweep polarography, cycle-voltammetry, stripping voltammetry and chemical preparation Refering to the other authors' works, it can be deduced that UO2(cupf)2 is adsorbed at the electrode,The reduction of UO2(oupf)2 is the common effect of both UO22+and cupferron. two electrons participate the reduction of U(Ⅵ) to U(Ⅳ),while the reduction of 2 cupferron ions needs 8e.So the sensitivity of determining uranium is higher than that without cupferron.

通过单扫描指示波极谱法、循环伏安法、溶出伏安法及化学制备研究了在乙酸缓冲介质中铀及铜铁灵的极谱性能。结合前人研究成果,推论吸附在电极表面的是UO_2(Cupf)_2螯合分子。在溶出阶段,此螯合分子中的U(VI)还原为U(IV),两个铜铁灵离子为8电子还原。此螯合分子的多电子还原导致测铀灵敏度极大提高。所拟定的不经分离直接测ppb级铀的吸附溶出伏安法经多种样品分析考验,特别是国际原子能委员会标准水样比对,结果一致。证明具有实用价值。

The values of 4 nutrient ingredients from the seed samples of different varieties of5 cereal crops and the moisture content and hardness of wheat were determined byboth the NIRDRSA method and the state standard(or conventional)methods.Theresults indicated that the Correlated coefficients between the corresponding values ob-tained by these 2 methods for all the quality traits studied were all higher than 0.968and the variation coefficients were lower than 3.2%.Result of t-test showed thatthere was no significant difference between the values obtained by these two methods(P=0.05).Thus,after calibration,the NIRDRSA method could make it possible to handlequickly large amount of seed samples without weighing or any chemical preparation,leading to great potential in the improvement of the efficiency of quality tests and thescreening for better parental and segregating materials.

以国家标准或常规测定法为参照方法,应用 NIRDRSA 测定了5种作物不同品种籽粒样品中4种营养成分和小麦的水分及硬度值。两种方法所测各组定标和预测样品数值间回归相关系数均大于0.968,变异系数圴小于3.2%。经 t 检验,NIRDRSA 与参照法之间无显著差异(P<0.05)。NIRDRSA 经定标后,即可快速鉴定和筛选勿需称量和任何化学预处理的大批育种材料。这对于提高作物品质鉴定效率、增强选配亲本杂交组合的预见性显示出很大的应用潜力。

In this paper, the development of ulthefine powder preparation techniques are summarind andthe evaluation methods for powder properties are also introduced. Chemical preparation techniquescan produce ultrafine powder with excellent properties and now they are researched extensively in theworld. It is urgent to lower the high costs of chemical preparation techniqucs today. From now on,ultrafine powder preparation by mechanical techniques should be rescarched and developedcontinuously.
