1.最小与非最小相位系统的概念 如果系统的传递函数在右半S平面上没有极点 和零点,而且不包含滞后环节,则称为最小相 位系统,否则,称为非最小相位系统。 只包含比例、积分、微分、惯性、振荡、一阶 微分和二阶微分环节的系统是最小相位系统。 而包含不稳定环节或滞后环节的系统则是非最 小相位系统

11. 4. The nucleolus The most prominent substructure within the nucleus during interphase is the nucleolus. 100 years ago, one found a big spherical structure, called nucleolus within the nucleus, but up until 1960s, it was not identified that the nucleolus is a ribosome production factory designed to fulfill the need for large scale transcription and processing
