Most ovarian follicles undergo an involutional process called follicular atresia . 大多數(shù)卵泡都經(jīng)過退化變?yōu)殚]鎖卵泡。
From these - two forms , we determine the automorphism group aut ( h ) of the ( 2n + 1 ) - dimensional heisenberg lie algebra h ( see theorem1 . 1 ) . moreover , some subgroups of aut ( h ) are obtained , such as the inner automorphism group , the central automorphism group , the involutional automorphism group , the first and the second extremal automorphism group 第一部分安排如下:首先給出了heisenberg李代數(shù)的兩種定義形式,由這兩種定義形式,我們得到了( 2n + 1 )維heisenberg李代數(shù)h的自同構(gòu)群aut ( h ) (定理1 . 1 ) ;進(jìn)而給出了aut ( h )的一些子群:內(nèi)自同構(gòu)群,中心自同構(gòu)群,對(duì)合自同構(gòu)群,第一類外自同構(gòu)群,第二類外自同構(gòu)群。
