Moreover, we we sequenced the entire mitochondrial DNA control region from 17 charadriiform species, and found that the base composition and distribution of the variable nucleotide sites within the control region were similar to other avian species, but a series of short tandem repeated motifs in the 3' end of domain III made A nucleotides and length increased significantly. Phylogenetic analysis showed that these sequences could not well resolve the relationship among genus in Charadriiformes, but within genera maybe has some valuable phylogenetic information.

此外，本研究测定了鸻形目17种鸟类线粒体调控区序列，发现在碱基组成和进化速率上与其它鸟类相似，但其3'末端的串联重复序列导致domain III长度且A含量显著增加；利用调控区序列未能较好的解决鸻形目属以上水平的分类，但对于解决属内物种间的进化关系具有一定的参考价值。

In the incontinuous cutting, the wave shape of milling can be looked as periodic function. When the milling wave shape with single-tooth was looked as impulse function, by the Fourier Transform, we can find out that it is composed of sine wave with a given frequency and a series of integer multiple frequency. Discussing on the power function is a major tache for studying on the cutting capability of the complex three-dimension groove milling inserts, so to know the facts that affect the single-tooth milling spectral value, and to observe the dynamic milling wave property from the composition of the power spectral, thus we can design and optimize grooves.
