INTRODUCTION In a previous paper we made a statistical analysis of the redshifts z and apparent magnitudes m_v of 946 QSOs. The main points are: dividing the redshifts of the QSOs into 36 intervals with a step length of 0.1 calculating the mathematical expectation (?)_(v(z)) of the QSO's apparent magnitudes and the standard deviation in each interval and discussing the cosmological model based on the relation between (?)_(v(z)) and z.

摘      要：Ⅰ. INTRODUCTION In a previous paper, we made a statistical analysis of the redshifts z and apparent magnitudes mv of 946 QSOs. The main points are: dividing the redshifts of the QSOs into 36 intervals with a step length of 0.1, calculating the mathematical expectation （?）v（z） of the QSO’s apparent magnitudes and the standard deviation in each interval, and discussing the cosmological model based on the relation between （?）v（z） and z.
