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。

In order to separate copper from Huili lead-zinc complex sulphide ore,ore properties and separation process were investigated.

The high temperature metallurgical properties of several burdens for Anyang steel were investigated. The results showed that RIof high basicity sinters was better than others, but the RDI(low temperature reduction degradation index) of it was the highest; the RDI and molten dripping property of pellets and lump ores were well, so we can get rational burden structure by combining sinters for blast furnace.

系统分析了安钢炼铁生产中几种常用炉料的高温冶金性能，结果表明，安钢自产高碱度烧结矿具有较好的还原性，但其低温还原粉化率却是最高的；酸性球团矿及块矿则有着较好的低温还原粉化指数及良好的熔滴性能，能够与高碱度烧结矿搭配形成合理的综合炉料结构，满足高炉冶炼要求。

A method for the analysis of zinc oxide phase content in sulfide ore was studied. On the basis of the characteristics of each phase component, the sulfide ore sample was leached twice with NaOH and acetic acid-ascorbic acid, respectively, so that the oxide mineral and zinc oxide were dissolved completely. The leaching rate of zinc oxide phase was up to 98 Vo. Moreover, the dissolution of zinc sulfide phase was effectively inhibited, solving the problems of selective leaching and determination for zinc oxide.

研究了硫化矿中氧化锌相含量的分析方法，根据硫化矿中各物相组分特点，提出了用氢氧化钠溶液和乙酸－抗坏血酸溶液二次浸取硫化矿，使锌氧化矿、氧化锌充分溶解，氧化锌相的浸取率达到98%以上，同时有效地抑制了硫化锌相的溶解，较好地解决了氧化锌相选择溶解测定的问题。
