Our research showed that the genetic variation of raptors and nighthawks was abundant and that the number of transitions and transversions in 12S rRNA and 16S rRNA genes increased gradually with p-distance and appeared not to be saturated, which indicated the phylogenetic relationship made in this study was really reflected.

In the first part,two methods calculating the coefficients of nilpotentclass normal forms are proposed.one is the iteration search method based onrepresentation theory of Li-algebra,and another is a new matrixrepresentation method based on the adjoint operator concepts,both are ableto be used to analyse the normal form problems with high orders and largedimensions efficiently.

The inconsistencies of dimensional reduction and naive dimensional regularization in dealing withChern-Simons-matter theory are analyzed.The consistent dimensional regularization combiningwith higher covariant derivative regularization is adopted to consider Chern-Simons field theorycoupled to complex scalar and spinor field.All the local parts of one-loop two-point functionsand three-point functions are computed.Slavnov-Taylor identity is combined with these explicitcalculation results to give the one-loop local effective action.The finite gauge invariant quantumcorrection is shown and finite wave function renormalization constant for each field is defined.Thelocal part of one-loop three gauge field vertex is especially evaluated and it is verified that thereexists a renormalization choice compatible with BRST symmetry.

然后计算了所有的两点函数和三点函数单圈修正的定域部分，利用S-T恒等式给出了单圈定域有效作用量，定义了场的重正化常数，发现物质场和规范场都存在有限的规范不变的量子修正，并讨论了这些有限的规范不变的量子修正的物理意义，进而通过考察单圈三规范场顶角，表明存在与BRST对称性相容的重正化选择。5、在背景场方法的框架下，选择高阶协变导数正规化与维数正规化的杂化正规化方案计算了背景场两点函数的两圈量子修正，结果表明，标志紫外发散的极点项恰好抵消；进一步利用背景场方法中明显的规范对称性，证明背景场三点函数的两圈图贡献也是有限的。

Teachers should highlight the relationships among the three measures of Central Tendency in classroom teaching.3. Because it was found that students had difficulty in explaining their uses of measures of Central Tendency, teachers should pay more attention to cultivate students' communication abilities (including writing communication and oral communication) in math.4. Teachers should pay attention to students' errors and misconceptions, and provide pertinent teaching activities to deal with these errors and misconceptions.

注重统计知识在课堂教学中的有效实施。2、在教学中使学生进一步明确三种集中量数之间的关系和适用条件。3、由于在研究中发现高中生在解释选用集中量数的理由时有较大的困难，建立教师多注重培养学生数学交流的能力。4、教师平时应与学生多一点互动，多一点深入接触，从而能发现学生在理解集中量数中所发生的典型错误，并能及时帮助学生改正错误。
