世代数 meaning in English
generation number
Examples
- Computational results reveal that the hybrid genetic algorithm can efficiently solve the considered problem and the reduction of makespan is related to the mutation rates and the number of generations
结果显示，混合式基因演算法可有效的求解测试问题，最大完工时间的降低和突变机率与世代数相关。 - The result showed that the factors of different germination levels and generation times did not affect the genetic integrity during the regeneration in the case of often cross - pollinated crops like cotton
本试验表明不同更新发芽率水平和繁殖世代数差异没有对棉花这种常异花授粉作物种质遗传完整性变化产生影响。 - The performance of the proposed hybrid genetic algorithm is evaluated by two real - world problems and the solution quality of the proposed approach is analyzed under five levels of mutation rates and four levels of number of generations
此混合式基因演算法的绩效将透过两个实务的问题的求解加以测试，并且根据五种突变机率与四种世代数进行分析。 - It showed that the differences of allele frequency among the populations regenerated from the accession samples with different germination level or the populations obtained from the accession samples with different generations were not significant , and there was no absence of rare alleles observed
结果表明，无论每一份不同更新发芽率水平繁殖后代的种质之间，还是每一份不同繁殖世代数种质之间，其等位基因频率差异不显著，也没有检测到稀有等位基因缺失的情况。 - The tiller - nodes of 6 species of rhizome grass , including leymus chinensis , hemarthriajaponica , arundinella hirta , calamagrostis epigeios , c . rigidula , hordeum brevisubulatum in songnen plain , can live at best for 2 to 5 years , and do 2 to 4 propagating generations which is the same as the age class of tiller in number . the age structure of population is an increasing model which the young tiller is more than the old at quantity and biomass . during the whole growing season , the age spectrum varies for each species
松嫩平原，羊草、牛鞭草、野古草、拂子茅、硬拂子茅和野大麦等6种根茎型禾草种群的分蘖节最多可以存活2 5个年度，可以进行营养繁殖2 4个世代，分蘖株的龄级数与分蘖节营养繁殖的世代数相同，在种群分蘖株的数量和生物量上，生长季的各个时期均以幼龄分蘖株占较大比例，呈现为明显的增长型年龄结构，各种类的年龄谱组成各异。
