英文摘要We present 206 unpublished optical spectra of 104 type II supernovae (SNe II) obtained by the Xinglong 2.16-m telescope and Lijiang 2.4-m telescope during the period from 2011 to 2018, spanning the phases from about 1 to 200 d after the SN explosion. The spectral line identifications, evolution of line velocities and pseudo-equivalent widths, as well as correlations between some important spectral parameters are presented. Our sample displays a large range in expansion velocities. For instance, the Fe II 5169 velocities measured from spectra at t similar to 50 d after the explosion vary from 2000 to 5500 km s(-1), with an average value of 3872 +/- 949 km s(-1). Power-law functions can be used to fit the velocity evolution, with the power-law exponent quantifying the velocity decline rate. We found an anticorrelation existing between H velocity at mid-plateau phase and its velocity decay exponent, SNe II with higher velocities tending to have smaller velocity decay rate. Moreover, we noticed that the velocity decay rate inferred from the Balmer lines (i.e. H alpha and H beta) have moderate correlations with the ratio of absorption to emission for H alpha (a/e). In our sample, two objects show possibly flash-ionized features at early phases. Besides, we noticed that multiple high-velocity components may exist on the blue side of hydrogen lines of SN 2013ab, possibly suggesting that these features arise from complex line-forming region.
