In chapter 1, one type of maximal subgroups in symplectic groups overpolynomial rings are obtained. Let F be a field, R = F be a ring of polynomial in one variable over F, m be a positive integer, f eF and S be the ideal of R generated by -f, We define:, then G is a maximalsubgroups of Sp(2m,R).

In this dissertation, a theorem to describe the relationship between the quotient group Aut/H and the set F_f is presented. And a way to find the elements of F_f that are conjugate to f is proposed. Then we prove that the quotient group Aut/H is isomorphic to S_3, the symmetric group of order 3, and H is a semidirect product group of GL_(m/2)(4) with the classical binary simplex code S_m in the linear case.
本文刻画了商群Aut/H与集合F_f的关系,给出了一个确定集合F_f中那些与f共轭的元素的方法,还证明了在线性情形下,商群Aut/H与3阶对称群S_3是同构的,而且H是GL_(m/2)(4)与经典单形码S_m的一个半直积,并且推关广了Calderbank等人的一个结果。

Twenty-four sites were sampled over three different periods in three rivers of the plateau. At each site, a riffle and a pool were identified, in a stretch of about 100 m, as separate habitat units, and were sampled for fish and physical habitat. A preference index and logistic regression were used to determine the important habitat variables for each species.
分3个时期选择3条河流的24个地点进行取样,每个样点长100 m左右;分急流和回水湾两种生境类型作为独立的栖息地单元取样,据此观察研究对象和物理环境间的关系;用喜好指数和逻辑回归分析每种鱼重要栖息地是否稳定。

1 Self-threading or sheet metal screws may be used if threads are not stripped when the screw is tightened with a torque of 3.39 N·m (30 lb·in) and if the part or the assembly supported by the screw withstands for 1 min a force equal to four times the mass of the part or assembly, applied in a direction coincident with the axis of the screw.
测试方法:用3.39N.m(30lb.in)的扭力扭紧螺丝,并在装配表面的螺丝轴向施加于四倍于装配物重量,螺蚊应不受破坏。本文由tinson2008在安规网发表,如果提示附件不存在,点我进入备份站下载!

Calcium carbonate and soluble glass and so on were confected as alkaline antifouling agent. The Infrared Spectrometry results showed that 2275-2250 cm~(-1) diagnostic absorb wave crest in part A and 3390-3200 cm~(-1) in part B and 1730 cm~(-1) in coating film strongly proved polymers reacted just as the reacting mechanism, that means polysiloxane which offer low-surface-energy property linked Polyurethane system by —OH groups reacting with —NCO groups. Relative molar mass of part A and part B was determined by Gel Permeation Chromatography and the results were appropriate. Surface-energy was determined and results were between 33.6-47.17 mN/m and it increased when alkaline antifouling agent was put into the coating. Alkaline antifouling agent was releasing steadily when the coating film was dipped in seawater. As time gone, the pH value of seawater was increasing. Solubility parameter and results showed that there was no corrasive phenomenon between the polyethylene strand and the coating.
红外光谱分析结果表明,出现在A组分中的2275~2250cm~(-1)处的异氰酸酯特征吸收峰、B组分中的3390~3200cm~(-1)处硅羟基的特征吸收峰及出现在固化后涂膜中的1730cm~(-1)处氨基甲酸酯基团的特征吸收峰证明了涂料成膜物质交联固化符合本文的设计要求,即赋予涂膜低表面能特性的有机硅组分通过—OH基团与—NCO基团的反应已经链接到聚氨酯体系中;凝胶渗透色谱结果表明,成膜物质的A、B组分均为低分子量,符合预聚物的要求;涂膜表面能的测算结果表明,涂膜的表面能在33.6~47.17mN/m之间;加入碱式防污剂后涂膜的表面能略有升高;碱式防污剂的释放平稳,随着涂膜在海水中浸泡时间的增长,pH值有增加的趋势;用溶解度参数原则来评价涂料与网绳的涂装,结果表明,本试验研制的防污涂料对聚乙烯网绳无溶蚀作用。
