查询词典 ratio

Here's two thing you may want to write down: The first is Aspect Ratio.

这里有两个你需要记住的东西：第一个是Aspect Ratio，要麼是16：9要麼是4：3

The proposed method is based on a higher order likelihood-based asymptotic procedure. The merits of the proposed method are numerically compared with the signed log-likelihood ratio statistic and the simple t-test method with respect to their expected lengths, coverage probabilities and type I errors.

我们所利用的方法是以概似函数为基础的高阶近似方法，并且我们利用模拟的方法去跟signed log-likelihood ratio及 simple t-test 两种方法比较所建构出的信赖区间的覆盖机率和平均宽度以及所对应检定的型I错误来检视我们所利用方法的优劣。

We also find that among the three investment strategies we discussed – the momentum strategy, buying the top or the bottom decile portfolio of funds, adopting the momentum strategy gets a better Sharpe ratio if the emerging market, energy, and mineral funds are not considered. For the portfolio of emerging market, energy, and mineral funds, it is with better performance for the strategies of buying the top or the bottom decile portfolio of funds.

最后，以Sharpe ratio为比较各投资策略在各投资分类的基准，采取动能策略操作基金，在移除新兴、能源、矿业基金之投资组合中有较高的报酬；又以买入形成期表现最好及买入形成期表现最差的基金为操作策略时，在新兴、能源、矿业基金这一分类出现较佳之绩效。

In mathematical terms, the Facing Ratio is the Dot Product of the angle rather than the angle itself.

在数学术语上，Facing Ratio是角度的数量积相当于角度本身。

In addition, the changes of evertor/invertor ratio after recurrent inversion sprains are not clear.

另外，外翻肌／内翻肌比值(evertor/invert ratio)在脚踝扭伤后的改变也仍不清楚。

The prevalence of diabetes in men significantly increased from the first quartile to the fourth quartile of BMI and the waist-hip ratio (4.48% to 9.21% in BMI, 3.67% to 13.61% in WHR), while the prevalence in women also significantly increased from the first to fourth quartile (2.45% to 11.76% in BMI, 2.04% to 13.49% in WHR).

依体质量系数和腰臂比(waist-hip ratio)来分为四分位，从第一分位在第四分的男性糖尿病盛行率有明显增加(体质量系数从4.48%至9.21%，腰臂比从3.67%至13.61%)，而女性糖尿病成行率，从第一分位至第四分位也是一样有明显增加(体质量系数从2.45%至11.76%，腰臂比从2.04%至13.49%)。

This retrospective study included three medical institutes and fifty-nine patients of Alzheimer's disease. Based on spectral analysis, we calculated and presented spectral profile、power ratio、interhemispheric alpha coherence and intrahemispheric alpha coherence of individual EEG.

本研究收集三个专科医疗机构、59 位阿兹海默病患的数位脑波资料，利用频谱分析计算并呈现 spectral profile、power ratio、interhemispheric alpha coherence 和 intrahemispheric alpha coherence 等指标。

At last, this study also takes the sensitivity analyses of input parameters for the prediction equations. The result shows that Bowen Ratio is the most influencing surface parameter for the development of the MH and the same with the potential temperature lapse rate in the layer above mixing height.

本文亦针对混合层预测式所需输入之各参数进行敏感度分析，结果显示Bowen Ratio为影响混合层发展最显著的地表参数，而混合层上方位温斜率值对於混合层高度的发展亦有相当程度之影响。

近来性能较为显著的基于PSO算法的改进算法有Thanmaya Peram[10]等人于2003年提出的基于粒子群优化的适应值-距离-比例算法(Fitness-Distance-Ratio based Particle Swarm Optimization， FDR-PSO)，在此算法中每个粒子根据一定的适应值-距离-比例原则，向附近具有较好适应值的多个粒子进行不同程度的靠近，而不仅仅只向当前所发现的最好粒子靠近。

The normal visual field and the normal C/D ratio did not mean that the nerve fiber layer was normal.

正常的视野及正常的C/D ratio均不能代表其网膜神经纤维层是正常的。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
