摘　　要：本文利用我们所参与的1993年的国际联测光学资料，对NGC4151的BLR进行了后续ReverberationMapping分析，其中包括a）Monte-Carlo数值模拟检验谱线光变对连续谱光变响应的最可靠的延时时标，b）用正则线性化反演方法解出BLR的转移函数．我们分析并具体解释了对NGC4151的BLR尺度的最新测量结果同1988年的测量结果存在极其显著差别的原因．We applied the reverberation mapping (RM) technique to Seyfert galaxy NGC 4151 by using the optical monitoring data obtained in an international AGN wateh campaign in which we took part in 1993. The following tWo kinds of RM analysis were carried out: (1) to clarify how a specific continuum variation can affect the delay of emission lines by use of Monte Carlo simulation; (2) to solve the BLR transfer function, which describes the size and structure of the BLR in NGC 4151,with the regulalized linear inversion method. We have found that the tusfer function of NGC 4151 drastically changed from itS shape in 1988, and thes is explained and discussed in the last section of this paper.
