The result ofpairwise Fst and Neutrality tests revealed significant genetic differentiation amongfour populations,and evolution of mtDNA COI gene incompliance with the Neutralitytheory.The genetic distance was the biggest between HEB and JXL,and was thesmallest between SDT and JXL among the 4 populations.

遗传多样性研究采用了线粒体DNA COI基因序列、RAPD和PCR-RFLP三种分子标记研究大猿叶甲4个地理种群的遗传结构和群体遗传多样性。1、对长约335bp的mtDNA COI片段进行序列分析，在4个群体64个个体中，共发现37个单倍型，总变异位点35个，多态位点29个，含量(63.68％)大于含量(36.32％)。4个地理种群的核苷酸多样性指数分别为，0.082、0.035、0.099、0.186。

During the actual production, that the oxygen contamination from the crucible material by heat composition increases the oxygen content of molten steel will result in melting losses of the alloys in the molten steel, and will results in more heavier melting losses of the alloys, incontrollable exact chemical content of molten steel, increment of oxide inclusions and bad processability and serviceability, especially in the high strength(σb≥1600MPa) steels and alloys with special performance used in aerospace industry, manufacturing industry for precision instruments and meters, military industry, nuclear industry etc. because these steels usually have a high content of some active alloys such as Ti, V, Nb, Al, RE, etc. and a nearly zero content of dissolved oxygen.

实际生产中，如果炉衬热分解向钢液供氧，势必会造成钢液中合金元素的烧损，尤其是在航空航天、精密仪器仪表制造、军工及核工业部门使用的某些具有特殊性能的高强度(抗拉强度σb≥1600MPa)合金或钢材，因它们通常需要具有较高的活泼合金元素(如Ti、V、Nb、Al、RE等)含量，且钢中溶解氧含量接近于零，炉衬热分解供氧将造成这些合金元素的大量烧损，其结果是钢液化学成分难以精确控制，并增加了氧化物夹杂含量，恶化了钢的加工和使用性能。

The lipid peroxidation of S. maxima cultured in the presence of 4 to 100mg Se/L analysed showed that the contents of free radicals by EPR and malondialdehyde increased, of which the latter was the products of lipid peroxidation. These resulted in the decrease of the contents of liposoluble matter and percentage of polyunsaturated fatty acids, and the increase of percentage of saturated fatty acids. Using dimethyl sulfoxide , which was oxidized by OH·to form the stable and nonradical compound, methane sulfinic acid , as a molecular probe, we found that the contents of MSA from S. maxima growing in the presence of selenium were higher than those without selenium added, i. e. selenium in vivo was able to scavenge OH. in this alga.

对4～100mg Se/L范围内培养的S.maxima进行脂质过氧化的分析结果表明，加硒条件下藻细胞EPR自由基的含量与脂质过氧化产物的含量增加，造成细胞脂溶性物质含量和不饱和脂肪酸百分含量下降，以及饱和脂肪酸的百分含量相对上升；使用DMSO作分子探针，用它与OH·的反应产物MSA来表示藻细胞OH·含量，发现加硒条件下藻细胞MSA含量低于未加硒的，即硒在藻细胞内具有清除OH·作用。
