查询词典 variability

Uncertainties exist in either aleatory variability or epistemic uncertainty, but a weighted average of various alternatives in probabilistic seismic hazard analysis and the combination in methodology of PSHA and DSHA (deterministic seismic hazard analysis) should better prevent it from producing an extremely biased output of hazard estimates.

由于输入模型中不确定因素的存在，如输入参数的随机性和科学分析方法本身的不确定性，对分析结果的不确定性需审慎对待。通常对不同的模型或参量，包括地面衰减模型，进行加权平均可较为合理地减小结果的偏差。概率分析和确定性分析方法的结合亦为可取之有效途径。

In 10-20s period band, the sources of ambient seismic noise has a very clear seasonal variability.

由于短周期面波强烈的衰减和吸收效应，提取出的这一周期段的瑞利面波格林函数的信噪比较低。

The concentration variability of IPC with time from analog data coincided with the experimental data.

通过模型的模拟结果发现单体浓度、聚合物浓度随胶囊半径的变化规律。

Because of the non-linearity, time- variability, multi-parameter, intense coupling of the heating process and especially, the random interfere and anfractuosity of process, precision mathematics model is difficult to be established. The routine PID algorithm can not meet the requirement of control.

高岭土回转窑的加热过程中存在非线性、时变性、多参数强烈耦合这些问题，且随机干扰以及过程机理错综复杂，难以建立被控对象的精确数学模型，采用常规的PID算法很难达到控制要求。

Large variability of the monthly mean Angstrom exponent is also found in Miyun and Xinfeng, but there is no tendency with seasons.

密云和新丰的Angst rom指数也有很大的月际变化，但没有明显的季节倾向。

Fifty-four SRAP primers were selected to analyze genetic variability among 28 accessions of Arachis section from 11 species. A dendrogram and principal component analysis were constructed based on our data.

利用54对SRAP引物分析花生属花生区组11个物种28份材料间的遗传变异。

That indicated the availability of SRAP technique in studying genetic variability in Arachis. Estimates of genetic distance among the 28 accessions Arachis section ranged from 0.12 to 0.75 with average genetic distance of 0.42. A genetic distance clarified that A-genome A. duranensis was most closely associated with tetraploid germplasm, which could be A-genome donors. Dendrogram of cluster analysis classified 28 accessions Arachis section into two groups: one including tetraploid germplasm, and A.

聚类分析表明，28份花生材料间的遗传距离变幅为0.12~0.75，平均为0.42，A基因组物种Arachis duranensis与栽培种花生的亲缘关系最近，可能是栽培种花生的A基因组的供体。28份种质分为两大类，第一大类包含四倍体种质及A基因组的A。

The environmental effects of temperature variation and buoyancy variability due to barometric pressure fluctuation can be arithmetically tared out of the weighing values.

温度变化以及由于大气压变化引起的浮力变化的这些环境影响可以在称重数据中去除掉。

Objective To investigate the change of heart rate variability in patients with primary hypertension and its relationship with ventricular arrhythmia.

目的 探讨高血压病者24h心率变异性的变化及其与室性心律失常的关系。

We have limited budget let me know if you can do this competitively.

我们有限的预算让我知道如果你能做到这一点竞争力。

We don't know how other critters breathe--lizards, for example.
