The allelic diversity in terms of number of alleles per locus and expected heterozygosities in cultured populations N=8.0-9.4, H(subscript e=0.754-0.787 was considerably lower than that found in the wild populations N=11.3-15.0, H(subscript e=0.821-0.866. Allele distributions at all seven microsatellites indicated that the cultured populations lost some rare alleles belonging to wild populations. The small number and the biased sex ratio of abalone for hatchery broodstock might be responsible for the remarkable reduction of genetic variation in the studied populations.

结果表明，从等位基因数与杂合度上分析，养殖群体(N=8.0~9.4， H=0.754~0.787)遗传多样性显著低于野生群体N=11.3~15.0， H(下标 e=0.821~0.866；等位基因频率分布揭示出野生群体中一些稀有等位基因在养殖群体中有所丢失；亲鲍选用数量少与性别比例不均衡可能是产生养殖群体中遗传多样性显著减少的原因。

In this paper, the quality of unstructured grids generated by Delaunay Triangulation Method and Bubble Packing method is compared by the classical lid-driven square cavity flow solved by SIMPLE algorithm on collocated unstructured grid. The velocity distributions on vertical and horizontal center lines are in good agreement with bench mark, which shows that both of the two grids can be used in CFD.
