The solvable Lie algebra is corresponding to a cascade decomposition of the system and the semisimple Lie algebra is corresponding to a qasi-parallel decomposition such that the system has a parallel form of a cascade decomposition and a qasi-parallel decomposition.

任一李代数都可分解为一可解李代数与一半单李代数的半直和，可解李代数对应于系统的级联分解，半单李代数对应的是系统的准平行分解，将二者合并起来，就得到一般李群下的非线性系统的结构分解，这是一级联形式与一准平行形式的并联形式分解。

To eliminate common-mode voltage of cascaded multi-level inverter, three kinds of phase-difference SVM based on left and right bridge vectors are proposed firstly. From these three modulations, equivalent SPWM components are deduced, and the unipolarity and bipolarity of output waveforms are analyzed. 2π/3 PD-SVM (phase-difference space vector modulation) is testified be unipolar.

为消除级联型多电平逆变器的输出共模电压，首先提出了基于左、右桥臂矢量的三类相差空间矢量调制(space vector modulation，SVM)技术，数学推导出三类调制技术的等效正弦脉宽调制(sine pulse width modulation，SPWM)的调制波，并分析了其各自相电压输出波形的单、双极性，证明2π/3相差SVM必为单极性调制。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
