The result indicated that 237 combinations amplified a total of 13 079 AFLP fragments with an average of 55 fragments, the average of 1.30 markers per 1 000 AFLP fragments were found to be linked to clubroot resistant gene; the amplified polymorphic fragments were 3 167 between the two parents, account for 24 percent of polymorphic frequency; the number of amplified fragments and the number of polymorphic fragments was in positive linear correlation; GC content of AFLP primer combinations significantly affects the number of amplified fragments and the number of polymorphic fragments, indicating negative linear correlation between them.

结果表明：平均每个组合检测到55条带，共扩增13079条带，平均每1000条带检测到1.30个根肿病抗性基因连锁标记；多态性带数为3167条，双亲间多态性频率约为0.24；扩增带数与多态性带数呈线性正相关，引物组合中的不同GC含量与扩增带数和多态性带数存在显著性差异，并表现出线性负相关。

Long ago there was a boy with bad temper.his father gave him a bag of nails and told him to knock in a nail into the fense around the yard when he got angry or quarreled with others.the first day the boy drove 37 nails into the fense.a couple of days later ,he learned to control himself so that he drove fewer and fewer nails as days past.he found it that it was easier to control his temper than knock in a nail.finally he nailed not even a nail a day ,he was so happy to tell his father.

Lanczos method is optimized in LDLT triangular decomposition 、 vector reorthogonalization and result judgement. At the same time a new method of result judgement is brought forward, and named mode compare method. The example proves the optimized results of the method.

在LDLT三角分解、向量重正交及丢根判断等步骤上，对Lanczos算法进行了多步优化，同时提出了新的丢根判断方法——模态比较法，并给出算例对优化效果进行了验证。
