Sieve numbers 10mm to 0.063mm were used for the sieve analysis of the sand and the gravel used in this experiment [7].
Let A denotes the set of the odd sieve numbers. In this paper, we use analytic method to study the mean value properties of this sequence, and give two interesting asymptotic formulae.
