Here we clarify that areal-type of a genus is defined by concluding distributions of all species in the genus, therefore specific distribution types are not the same as their generic areal-types except monotypic genera. Similarities of composition of areal-types between compared regional floras do not necessarily represent their floristic similarities because the same generic areal-type can be composed by different genera from different plant families.
根据植物区系学理论,属的分布区是该属内所有物种的分布区的集合,除单种属外,不能直接套用属分布区类型作为该属内各个种的分布区类型;亲缘关系疏远的不同植物属可以有同样的分布区类型,若把不同地区植物区系各地理成分的比例关系的类似性解读成各地区间植物区系的亲缘关系,显然是不适合的。

In this study, 0.94(Bi0.5Na0.5)TiO3-0.06BaTiO3 is a composition within morphotropic phase boundary. It was prepared by solid state reaction method. The dense ceramics with various grain size distributions were prepared by adjusting process. And grain size effect on crystal structure, dielectric, ferroelectric and piezoelectric properties were studied in detail.

The average taxonomic distinctness Δ+ was the highest in the southern Yellow Sea and lowest in the central Yellow Sea; the spatial variations were largely caused by the different spatial distributions of species belonging to orders Perciformes, Pleuronectiformes, Clupeiformes and Scorpaeniformes, especially those of cartilaginous species.
在区域尺度上,分类多样性指数Δ,分类差异指数Δ+在黄海中、北部较高,南黄海较低;等级多样性指数Δ+为南黄海最高,中黄海最低,其区域尺度变化主要是由鲈形目、鲽形目、鲱形目和形目种类,特别是软骨鱼类的种类数的分布变化造成的。
