查询词典 variation factor

The result indicates that:(1) the coefficients of variation of all strains' quality character are different, so it is effective to select qualitative character from the descendants;(2) the content of fat and content of water-soluble protein are remarkably negative correlation among variation strains.

结果表明：(1)所有品系的品质性状的变异系数差别较大，说明在后代中进行品质性状筛选是有效的；(2)突变品系内脂肪含量与水溶性蛋白含量呈显著负相关。

The south and north of the windward side of the Annam Cordillera show great difference in the diurnal variation of rainfall, which is related to migration of rainfall. Rainfall over coastal areas of the Thailand Gulf in 01-04LST migrates to inland northeastwards and then heavy rainfall occurs over areas southwest of the Annam Cordillera in 16-19LST, after that heavy rainfall migrates northwestward along the Annam Cordillera to areas northwest of the Annam Cordillera in 01-04LST in the next day. The migration of rainfall results in different characteristics of diurnal variation on the windward side of Annam Cordillera.

长山山脉西侧迎风坡的一南一北两个区域，表现出明显不同的降水日变化特征，其原因与降水的传播有关。01-04LST，降水大值区出现在泰国湾东部沿海，并向中南半岛岛内传播，16-19LST在长山山脉西南侧形成降水大值区，之后降水进一步沿山脉向西北传播，并于次日01-04LST传到长山山脉西北侧区域，通过降水的这种传播特征从而导致长山山脉迎风坡一侧不同的降水日变化特征。

The results showed that the number of chromosome, which was from the cultured seedlings of meristem tip and the rank seedlings of meristem tip, was not altered, both the number were 2n=16,the hereditary stability of callus and regeneration plant was poor; and the variation percentage of chromosome in callus was 43.4%, among which haploid accounted for 6.7%, triploid accounted for 2.5%,tetraploid accounted for 10%,pentaploid accounted for 4.2%,hexaploid accounted for 3.3%,septuploid accounted for 4.2%,octoploid accounted for 3.3%,dysploid accounted for 9.2%;the chromosome variation percentage of differentiation seedlings derived from callus was11.7%,among which haploid was 6.7%,triploid accounted for 1.7%,tetraploid was 3.3%.

结果表明，茎尖分生组织培养的幼苗及丛生苗遗传稳定，其染色体未发生倍性变异，均为2n=16；愈伤组织及其再生苗遗传稳定性较差，愈伤组织染色体数变异率为43.4%，其中单倍体占6.7%、三倍体占2.5%、四倍体占10%、五倍体占4.2%、六倍体占3.3%、七倍体占4.2%、八倍体占3.3%、非整倍体占9.2%；愈伤组织分化苗染色体变异率为11.7%，其中单倍体占6.7%，三倍体占1.7%，四倍体占3.3%。

Regional variation difference was very large with more ice in the eastern Antarctic, obviously less ice in the west Antarctic, both sides of the Antarctic Peninsula, especially in the Weddell Sea and the Bellingshausen Sea. The sea ice variation trend in the eastern and western Antarctic is always in opposite phase.

研究表明20世纪70年代后期是多冰期；80年代是少冰期；90年代南极海冰属于上升趋势，后期偏多，区域性变化差别大，东南极海冰偏多，西南极海冰即南极半岛两侧尤其是威德尔海区和别林斯高晋海的冰明显偏少。

The book, third edition, introduces the principles of genetics and statistics that are relevant to population studies, examines the forces affecting genetic variation from the molecular to the organismic level, and descripts molecular methods used to study variation in natural populations, as well as explanes the relevant estimation theory using actual data.

该书第三版，介绍与种群研究有关的遗传学与统计学原理，检测从分子到生物体水平遗传变异的影响因素，以及描述用于自然种群变异研究的分子方法，和运用真实数据解释相关的估计理论。

This means that poorer countries with low income-variation can outscore richer ones with high variation.

这意味着在居民收入差异较小的穷国，人们的生活状态要好于收入差距大的富国。

Results show that the cooling capacity and the COP of the system vary with the variation of the operation conditions;system faults such as solution crystallization,overhigh working pressure, freezing of cooling water or chilled water will be caused if the variation of the operation conditions is out of range.

计算结果表明：系统的制冷量和COP随运转条件的变化而变化；运转条件的变化需要控制在一定范围内，否则将引发溶液结晶、工作压力过高、冷剂水或冷冻水结冰等系统故障。

Using the principle of tilt variation, this paper analyzed the structures in the eastern part of the Linqing Depression , and summarized the basic structural characteristics of caprock sequences in the Paleogene and the controlling function of tilt variation to deposit.

该文应用掀斜变动原理对临清坳陷东部的构造进行了分析，并总结了下第三系盖层层序的基本构造特征和断块掀斜变动对沉积的控制作用。

Chapter 4 is the central part of this dissertation, where the bayes bilateral integrated moment is established on the base of Bayes theory, downside risk and upside potential. According to the variation coefficient which is based on the M-V approach, we substitute lower partial moment for the numerator of variation coefficient, and use higher partial moment as the substitute of the denominator, then we got bilateral integrated moment. Subsequently, through Bayes method we can absorb new information, revise the return distribution from transcendental distribution to posterior distribution, so we got bayes bilateral integrated moment.

第四章是本文的核心部分，在简要介绍Bayes理论、下方风险和上行潜能的基础上，仿照来源于Markowitz的均值——方差理论的变异系数方法，以下偏矩取代其分子部分，以上行潜能取代其分母部分，设计了双侧综合矩方法，接着再引入Bayes方法，吸纳新信息，采用后验概率，设计了Bayes双侧综合矩方法，并在理论上说明了新方法的优越性。
