给出了银河面l=54°附近1°5×1°5区域的射电连续谱图，分辨率为100角秒×200角秒。壳源G54.4-0.3具有超新星遗迹的特征，第二大环状结构G53.9+0.3是由W52和几个小直径热源组成的Hn环。十二个小直径源中的一个(G54.73+0.61)的光谱指数为⇏-1.6。
A radio continuum map of a 1°5 X 1°5 region in the galactic plane nearl= 54° is presented at 49 cm with a resolution of 100 arcsec X 200 arcsec. The shell source G 54.4 - 0.3 has the characteristics of a supernova remnant while the second large ring structure G 53.9 + 0.3 is a Hn ring consisting of W 52 and several small-diameter thermal sources. One of the twelve small-diameter sources (G 54.73 + 0.61) has a spectral index⇏ -1.6.
