For example, the phylogenetic trees constructed by NJ, ME, or MP methods basing on 12S rRNA complete sequence, indicated Falconidae branched off prior to the other avian, but the UPGMA tree placed Falco peregrine into a single branch and formed sister group with Accipitridae species and Strigiformes specie.

在基于12S rRNA全序列构建的NJ、ME和MP树中都支持隼科最早分化出一个单系群，而在UPGMA树中，隼科游隼单独形成一个分支，与鹰科、夜鹰目和鸮形目互为姐妹群。

60Co-γray was a useful mutagen in induced mutation breeding .After treated with 60Co-γray ,free-living conchocelis of wild Porphyra haitanensis were induced and represented in offsprings. Purple mutant and excellent practical characters strains were selected from a lot of gametophytic blades. Single cell clone and enzymolysis were used to propagate fast in pure strains of induced mutations.

Since the analytical solution was derived under the condition of an-infinitely wide slope, the shape of parabolic sections of general grassed channel needs to be considered. This work uses the results of Hey (1979) to build the shape factor, which can be used to design a grassed channel with a parabolic section.
