给出了统计引力放大效应对宇宙学红移体积检验影响的一般公式。这些公式被用来分析洛和Spillar（1986）的数据，他们测量了通量大于某个阈值通量的星系数目和这些星系的总通量，并得到了Omega（0）的值约为1。如何深入放大影响宇宙学参数的结果值进行了研究。发现引力透镜对观测宇宙学的影响是不可忽略的。参考文献24篇。
General formulations are presented for the effects of statistical gravitational amplification effects on the cosmological redshift-volume test. The formulations are used to analyze the data of Loh and Spillar (1986), who measured the number of galaxies with fluxes larger than some threshold flux and the total flux of these galaxies and obtained a value of Omega(0) roughly one. How deeply the amplification affects the resulting values of the cosmological parameters is studied. It is found that the gravitational lens effects on observational cosmology cannot be negligible. 24 refs.
