比例分布

He remembers from his school days that the area of a circle is proportional to the square of its radius, and expects that in the case of a uniform distribution, the number of stations counted should increase like the sequence of number 1, 4, 9, 16, and so on.

他记得他学生年代的时候，一个圆形区域的面积和它的半径的平方是成比例的，所以他认为在均匀分布的情况下，汽油站的数目应该以1，4，9，16等等这种数列增加。

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。

如用肩胛下ST/(肩胛下ST+肱三头肌区ST)的比例表示的话，那么14—17岁时，相对骨龄早者与相对骨龄晚者相比，前者有较明显的向心型分布倾向。13—14岁时，早组的上述比值的年增长明显大于晚组。

It is shown that beams of reinforced average strain distributing accord with flat section assume; The method of strengthening intension of concrete structure with reinforced materials is a feasible way. The strength of beam can be increased with the number of reinforcement materials be added; The strength of beam is affected by percentage of flexural reinforcement and the compound proportion and fashion of reinforcement materials and the number of reinforcement materials; The capability of bend and stretch and price of inner hybrid fiber is better than sole fiber and exterior hybrid fiber.
