在左截断右删失下，本文讨论了一类广义Von－Mises泛函估计的渐近性质．在一定条件下，得到了此类泛函估计的强逼近和U-统计量表示，并由此得出它的强相合性、渐近正态性及重对数律．

This paper deals with the estimation of a general class of Von-Mises type functionals of the survival function based on left under truncated and right censored data. The strong approximation and an almost sure asymptotic representation are obtained under some conditions. In addition, the asymptotic normality, strong consistency and the law of iterated logarithm for the estimator are established.
