　　A new technique for estimating quiet day curve (QDC) was suggested.To validate the new approach, QDCs were derived from data acquired by the imaging riometer installed at the Chinese Zhongshan Station in Antarctic.The evaluation was performed by comparing the difference between the QDC derived by the new technique and those derived by Tanakas technique [17].The results were discussed in terms of the diurnal variation and discrepancy.Also, cosmic noise absorption (CNA) images were built using both techniques in order to evaluate the implications of the changes in the methods of QDC determination on the CNA that resulted from it.The influence of the multiplicative factor value on the QDC determination in Tanakas technique was evaluated and a proper value was suggested.
