Strong [CII] emission has been ubiquitously detected all over the region between 1 = 30ﾟ and 51ﾟ, and the intensity distribution is rather smoot extended far from discrete luminous HII regions. Latitudinal and longitudinal pr the [CII] intensity distribution are quite similar to those of ^<12>CO(J = 1-0) resemble those of IRAS flux, while they are completely different from those of The diffuse [CII] emission probably comes from the C^+ regions (a part o photodissociation regions), which are illuminated by the general interstellar UV field and form as mantles of giant molecular clouds traced by ^<12>CO. The ext density ionized gas may also contribute to the diffuse [CII] emission. The mass resions is at least 40% of that of CO molecular gas. The total energy of the [emitted from the inner Galactic disk amounts to 2.8 x 10^7 times of the solar 1 which corresponds to 0.36% of the total far-infrared luminosity of the same regi

强[CII]发射在1 = 30 nm到51 nm之间的整个区域都被普遍检测到，并且强度分布相当平滑地延伸到远离离散的发光HII区域。[CII]的强度分布在纵、横向上与^<12>CO（J = 1-0）的强度分布相似，但与IRAS通量的强度分布完全不同。[CII]的漫射发射可能来自C^+区（光解区的一部分），这些区受到星际紫外光场的照射，形成被^CO示踪的巨分子云的地幔<12>。其质量分数至少为CO分子气体质量分数的40%。从银河系内盘发射的[]的总能量是太阳1的2.8 × 10^7倍，相当于同一区域远红外总光度的0.36%。
