| 摘要: |
| q1,q2是小参数,对于寻找Ramsey数R(q1,q2)的下界,我们给出了一个新的方法,用这个方法,通过使用计算机,给出了包括R(5,15)≥ 242在内的13个新的下界。 |

| Abstract: |
| A new method of obtaining lower bounds for some Ramsey numbers R(q1,q2) with small q1,q2 was presented.13 new lower bounds,including R(5,15) ≥ 242,were established by the method with the aid of computer. |
| Key words: Ramsey number lower bound cubic residues mod p |
