英文摘要	We examine chromospheric oscillations in both a coronal hole (CH) and a quiet Sun (QS) region, by employing Transition Region and Coronal Explorer (TRACE) and Big Bear Solar Observatory (BBSO) data on September 14 and 16, 2004. For the CH, the average oscillation periods of network magnetic field and non-magnetic field (NMF) regions are 257 and 222 s, respectively, and the average period of network field is longer than that of NIVIF region by 15.8%. In the QS, the average oscillation period is the 225 s for network field and 212 s for the NIVIF region. The average period of the network field is also longer than that of the NIVIF region by 6.1%. For the network region, we find that the average period in the CH is longer than that in the QS by 14.2%. This difference between CH and as is possibly caused by different magnetic configurations i.e. the open magnetic field in the CH and the close field in the QS.
