摘要
引入一种新筛法,通过在素数模的完全剩余系中划掉与起点同余的参数集,组合出经由n次筛减后的剩余数集。应用此法可直接寻找懦个区间内的素数、孪生素数、三生素数及任一偶数的"1+1"型式。
This paper introduces a new method of sieve, after deleting those parameter set from complete residue system of prime modulus which are congruent with starting points,combined to last residual set sifted n times. It is used to find prime, prime twins, prime three folds or different ways of '1+1' to an even integer in some interval.
