查询词典 Zn

Phytates,the salt form of PA chelating with cations such as K~+, Ca~(2+),Mg~(2+),Zn~(2+) and so on,are mostly accumulated in the aleurone and embryo part of cereal seeds.

植酸是作物种子中含磷最丰富的化合物，占种子干重的1%以上，种子全磷含量的65%-85%和酸溶性肌醇磷酸盐的90%以上，易与K~+、Ca~(2+)、Mg~(2+)和Zn~(2+)等金属离子螯合形成植酸盐，主要沉积在作物的糊粉层和胚中。

The contents of trace elements of Ag, Cu, Zn, Fe, Pb, Sb and Bi in gold foil were determined directly by ICP-AES method and the gold content of gold foil was calculated. The authors obtained optimal working parameters of the instrument and studied the selections of power in analytic conditions and analytic curve, the optimization of the pressure of nebulizer as well as the influence of lifting capacity of the sample.

摘 要：研究了ICP-AES法直接测定金箔中的Ag、Cu、Zn、Fe、Pb、Sb、Bi微量元素，通过差减法计算出金箔的含金量，确定了仪器最佳工作参数，研究了分析条件中功率的选取、分析线的选择、雾化器压力的优化、样品提升量的影响，并对金箔中Au基体可能存在的干扰等进行了探讨。

The content of mineral elements in ripe fruits of M.sieversii from 78 seedings at Mohe Town,Gongliu Country were analyzed using Atomic Absorption Spectrophotometer.The results indicated that M.sieversii seedings presented considerable genetic variations in content of mineral elements with the range of variation coefficients from 24.2% to 54.0%.So it has large potential for further selection.Four elite seedlings were selected,namely large fruit type,high Ca content type,high Zn content type and high damascenone content.As the predominant component of Ily wild fruit tree forest,Malus sieversii had occupied an area of 9300ha.But the inherent reproduction system of M.sieversii and genetic diversity of the species were destructed in different degrees,as a result of farming assart,over grazing and damage by Agrilus mali.

上述结果支持"新疆野苹果可能是栽培苹果祖先种"的结论；②对巩留县莫舍乡的新疆野苹果78个实生株系果肉组织Ca、Mg、Fe、Zn、Cu、Mn6种矿质营养元素进行测定的结果表明，每种矿质元素含量单株间差异显著，变异系数在24.2％～54.0％，遗传多样性丰富，进一步选择的潜力很大；③根据新疆野苹果果实形态、香味物质和矿质元素含量等的测定结果，初步筛选出了大果型、高钙型、高锌型和大马酮型等4个特异性状单株；④调查发现，由于农田开垦、过度放牧以及苹果小吉丁虫的蔓延危害，目前伊犁野果林面积逐年减少，野苹果固有的繁育体系和遗传多样性受到不同程度的破坏。

There are other metal arsenates, such as those of Fe,Zn,Cu, and Pb, which are less soluble and more stable in the neutral pH region than calcium arsenates or ferric arsenate, but these have not been seriously considered as disposal forms.

还有其他金属砷酸盐，例如那些 Fe、 Zn、 Cu和 Pb，比起砷酸钙或者砷酸铁来，这些物质在中性的 pH 值范围内很少是可溶并且更稳定的，但是这些物质没被以处理的形式认真慎重地考虑过。
