摘要
In the previous paper(Chin.Phys.lett.6(1989)233)the-amplification,luminosity distances and probabilities for lensing an the case of small optical depth were discussed.As the second part of this work,the present paper will deal with multiple images produced by pointlike lensing objects which are assumed to be the dominant contributors of inhomogeneities in the universe.The expectation values of image separations,the visual magnitude and solid angle of each image will be calculated.
