Results: Of the slight keratoconus group: the above indexes significantly decreased(P＜0.05). Of the moderate group: the above indexes, except for the apex decentration distance significantly decreased at 12 months and more evidently at 18 months. Of the severe group, the K value significantly decreased at 12 months and other figures remained unchanged. However, all the indexes significantly decreased except that the apex decentration distance remained unchanged at 18 months.

Compare to K type no.1B/1R male sterile line KTSP3314A,homotypic maintainer line TSP3314B and 1B/1R male sterile line K3314A,homotypic maintainer line 3314B at different developmental stages of superoxide dismutase,catalase,peroxidase activity and variety of malondialdehyde content.

利用K型非1B/1R类型小麦雄性不育系KTSP3314A，其同型保持系TSP3314B，以K型1B/1R类型小麦雄性不育系K3314A、其同型保持系3314B为对照，分别对其叶片和穗子在不同发育时期的超氧化物歧化酶、过氧化氢酶、过氧化物酶的活性和丙二醛含量的变化进行测定。

So the contents of Na〓 and Cl〓 in all inoculative plants were lower, and the ion quantities of N, P, K〓 and Ca〓 were higher than the control. At the same time, all kinds of tissue biomasses of inoculative plants relatively ascended which diluted the salt concentration of the inner plant and increased the accommodating quantities of the root and stem tissues to salt ions such as Na〓 and Cl〓.

结果表明，随着盐胁迫强度的增加，无论接种与否，各品种植株根系、茎部、叶片内Na〓、Cl〓含量均呈上升趋势，N、P、K〓、Ca〓含量呈下降趋势，由于菌根的形成增加了离子选择吸收特性，接种植株各部位Na〓、Cl〓含量低于对照，而N、P、K〓、Ca〓含量则高于对照植株。

Firstly, the K-means clustering algorithm was improved by using the rough set theory to determine initial cluster centroids.
