变异比

He suggests that this variation contributes to inspanidual differences in social behaviour—in other words, some voles will be more faithful than others.

他提出，正是这一变异导致了社会行为的个体差异，换句话说，一些田鼠将会比另一些更加忠诚。

Mitochondrial cytochrome b sequence were used to study the molecular evolution and phylogeny of Anser cygnoides(15 breed of Chinese goose), Anser anser(2 breed of domestic European goose) and Anser albifrons(the lesser white-fronted goose, Genbank accession number AF363031). Sequence analysis revealed that there were 29 variable sites and 4 haplotypes in 45 sequences, nucleotide diversity and haplotype diversity were 0.0068,0.45 respectively, insertion/deletion or frameshift mutation were not found in Cyt-b gene sequences(1143bp).

本实验测定了中国家鹅15个品种、欧洲鹅2个品种共44个个体的细胞色素b基因全序列，与Genbank库中自额雁细胞色素b基因序列合并在一起比对分析，17个家鹅品种和白额雁细胞色素b基因全序列均为1143bp，序列中没有缺失、插入或移码突变，共检测到29个变异位点、4种单倍型，核苷酸多样度和单倍型多样度分别为0.00648和0.45。

Statistic analysis showed that soil temperature as the driving factor to the diurnal variation of soil respiration. Soil temperature and soil moisture were the dominant environmental factors affecting the seasonal variation of soil respiration and explained 87% of its variability. LAI and root biomass were positively related to soil respiration rate, indicating that biotic factors also affected the seasonal variation of soil respiration. However, soil properties such as soil organic content, total nitrogen content, and C/N ratio had poor correlations with soil respiration. Top-dressing nitrogen fertilizer increased soil respiration significantly.

统计分析表明：土壤温度是玉米生态系统土壤呼吸日变化的驱动因素；土壤温度和土壤水分是影响土壤呼吸季节变化的关键因素，二者可以解释玉米生长季土壤呼吸时间变异的87%；LAI和根系生物量与土壤呼吸速率呈正相关，说明生物因子对土壤呼吸季节变化也有影响；土壤有机质、全氮和碳氮比等土壤理化特性与土壤呼吸速率的关系较弱；玉米生长季追施氮肥明显促进土壤呼吸速率。

Output data were then used to do S/N ratio and ANOVA analysis, to investigate the contribution of each factor to bending stiffness, and the optimal combination of levels could be predicted. Verification experiment was then carried out to confirm the optimized sandwich beam.

将所得数据进行讯号杂讯比及变异数分析来探讨各因子对弯曲刚性之影响趋势，分析出最佳之因子组合，之后进行验证实验来确认最佳化之复材三明治梁。

A variant was made by dealers in New Zealand for motorsport which had larger valves, two twin 40DHLA carburettors, modified camshafts and a higher compression ratio to produce around 125 bhp.

阿变异了对赛车运动在新西兰的交易商拥有更大的阀门，两张40DHLA化油器，修改凸轮轴和更高的压缩比产生大约125匹马力。

The results of computations demonstrate that the path relinking algorithm can obtain better solutions than the standard genetic algorithm, the standard Tabu search procedure and the general path relinking algorithm, and prove that the solution update method of the reference set with diversification detection is very important to path relinking. Moreover, the decentralization mutation strategy can enhance the capacity of searching a better solution.

计算实例表明，该路径重连算法比标准遗传算法、标准Tabu搜索算法以及普通路径重连算法能够获得更好的解，证明了多样性检测对参考解集更新的关键作用以及分散性解变异策略在提高解的质量上的能力。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
