光谱中的强发射线是活动星系核最显着的观测特征，通过发射线来研究活动星系核的物理性质是应用最广泛的方法，为理解活动星系核的本质提供了大量的信息。

Strong emission lines in spectrum is the prominent observation feature of ac-tive galactic nuclei ( AGNs ) . Using emission lines to study the physical properties of AGNs is the most widely used method , which provide numerous information to understand the nature of AGNs .

文中的表1包括100个发射线天体，其中的96个是发射线星系；其余的对象有3个行星状星云，1个发射线星。

We find a total of 100 emission-line objects , of which 96 are galaxies , the rest being 3 planetary nebulae and 1 star .
