摘要：

The edge-on spiral galaxy NGC4013 has been mapped in the J=2-1 and 1-0 lines of (CO)-C-12 with the IRAM 30m telescope (HPBW 13'' and 21''). CO emission is detected within a galactocentric radius, R similar to 100'' (5.5 Kpc), The radial molecular gas distribution consists of a ring-like source (of radius r(ring) similar to 1.5 kPc)) and a fast rotating nuclear disk (of radius r(nucl) similar to 500 pc).
