decamerous

1. In the RAPD profiles generated by 13 random decamer primers, there were no RAPD bands sharing by all the 29 isolates of 17 species, which revealed the abundant polymorphism among the tested isolates.

13个随机引物对17种拟茎点霉共29个菌株的扩增图谱中，没有发现所有拟茎点霉菌株的共有带，同时表现出种间差异大于种内差异的相同趋势，表明了供试菌株间存在着丰富的多态性。

2. 20 primers were screened from 100 random decamer primers,and a total of 258 DNA bands were amplified,253 of which(98.1%) were polymorphic.

从100个10碱基随机引物中筛选出20个多态性高的引物,共扩增出258条DNA带,其中253条为多态带(占98.1%),平均每个引物扩增多态性带12.6条。

3. Using 23 primers of arbitrary decamer oligonucleotide sequences were screened from 100 primers for DNA amplification, random amplified polymorphic DNA (RAPD) were used.

利用从100个随机引物筛选出23个稳定性较好的10碱基引物，对来自单蒴果的7代无性繁殖种苗进行RAPD检测。

4. Abstract： In the paper,shrinkage cavity formation of a hub S.G.iron casting was simulated with DECAM(Dynamic Expansion and Contrac tion Accumulation Method).

摘 要： 本文使用了收缩膨胀动态叠加（DECAM）法，对球铁轮毂的缩孔形成进行了模拟和工艺改进。
