摘　　要：本文作者首次对暗云Ｌ１２１１的Ｃ^（１８）Ｏ（Ｊ＝１－０）分子发射谱线进行了观测，发现了暗云Ｌ１２１１致密核的Ｃ^（１８）Ｏ（Ｊ＝１－０）的宽翼发射谱线和它的结构，得到了核区Ｃ^（１８）Ｏ（Ｊ＝１－０）分子的谱线轮廓图、强度分布图、速度分段积分等高图、速度位置图。The C(18)O(J=1-0) emission of dark cloud L1211 was observed. The widewing spectra of C18O(J=1-0) emission and the structure of dense core of dark cloud L1211 were found. The spectrum profiles, integrated intensity map, contour maps integrated over a 0.5 kms(-1) velocity range from V(LSR)=-13kms(-1) to -8.0kms(-1),and velocity-position maps were also obtained.
