摘要：

The UK 1.2 m Shmidt telescope was used to obtain two objective-prism plates and one direct plate of the area around NGC 1097, centred on 244.2. --30°29′.0 （1950.0） 37 quasar candidates are found within a 9 square degree region. Adding 6 QSOs found before, the total number of QSOs found in this area is 43.We have analysed the distribution of the QSOs around NGC 1097. The preliminary results are as follows: （ⅰ） The surface density of QSOs is very high near NGC 1097 and decreases with distance, from 15.2 to 2.0 per square degree. The average density is about 4.8 per square degree, （ⅱ） There is an obvious correlation between the jets and the QSOs. （ⅲ） It is difficult to explain the distribution of the QSOs by accidental probability or other reasons. This is a good evidence to suggest that the redshifts are non-cosmological.
